  • 본 연구는 구상나무림(Abies koreana Wilson)의 현지본전(現地保全)을 위한 종합적 연구의 일부분으로서, 지리산(智異山) 반약봉(般若峰) 지역의 구상나무림에서 식생유형별(植生類型別) 유수발생현황(維樹發生現況)을 파악하고, 타감작용(他感作用)을 통한 추수형성저해(推樹形成沮害) 효과(效果)가 존재(存在)하는지 확인(確認)하기 위해, 직생구성(植生構成)과 추수발생(推樹發生)과의 관계, 잎조직과 토양부식질(土讓腐蝕質) 중의 수용성(水溶性) 추출물(抽出物)이 구상나무의 종자발아(種子發芽)와 외생균근균(外生菌根菌)의 호흡활성(呼吸活性)에 미치는 타감효과(他感效果)를 조사하였다. 1996년 5월부터 8월까지 반야봉 해발 1400~1700m의 지역에서 20개의 $10m{\times}10m$ 크기의 방형구를 설치하여, 천연하종량(天然下種量)과 식생(植生)을 조사하였다. TWINSPAN을 이용하여 구분된 식생류형별(植生類型別)로 토양 부식질을 채취하고, 현지에 출현빈도(出現頻度)가 높은 5종의 목본식물의 잎을 채취하여 타감작용 시험에 사용하였다. 부식질 중의 수용성(水溶性) 추출물(抽出物)은 HPLC를 사용하여 수용성 phenol화합물의 양을 정량(定量)하였다. TWINSPAN에 의한 분류분석 결과 조사지역의 구상나무림은 구상-미역줄, 구상-신갈, 구상-철쭉, 구상-산철쭉 군락으로 분류되었으며, 이 중 구상-신갈군락과 구상 철쭉 군락은 조릿대의 유무에 따라 하부군락(下部群落)으로 분류되었다. 조사지역의 구상나무의 천연하종량(天然下種量)은 1995년 9월~10월 사이에 $230,000{\pm}90,0000$립/ha이었고, 발아율(發芽率)은 25%이었다. 1996년에 조사된 표고 5cm이하 유묘(幼苗)의 밀도(密度)는 평균 52,000본/ha이었으나, 묘고 5cm이상의 유묘의 밀도는 4,000본/ha로 감소하였다. 유묘의 밀도는 식생유형별로 큰 차이를 보여서 구상-신갈-조릿대 군락의 유묘의 수는 구상-신갈-철쭉 군락의 7%에 불과하여, 조릿대로 인하여 급격히 감소하였다. 털진달래와 조릿대의 잎 추출물은 구상나무의 종자발아(種子發芽)를 유의(有意)하게 저해(沮害)하였으며, 구상-신갈-조릿대 군락의 부식질 추출물도 구상나무의 종자발아(種子發芽)를 81%까지 유의하게 저해하였고, 조사지에서 분리배양된 두 종의 외생균근균(外生菌根菌)중에서 젖버섯 균사의 호흡속도(呼吸速度)를 유의하게 19% 감소(減少)시켜서 조릿대에 타감효과(他感效果)가 있다고 생각된다. 구상 신갈 조릿대 군락의 부식질에서 7가지 수용성(水溶性) phen이 화합물을 추출하여 동정하였는데, 추출물 중에서 수용성 페놀화합물인 p-hydroxybenzoic acid, vanillic acid, syringic acid가 유의하게 높았다. 특히 p-hydroxybenzoic acid는 조릿대 뿌리에 4.2ppm으로 존재하고, 조릿대 군락의 부식질에서 16.5ppm으로 발견되었으며, 종자발아 저해효과와 유의한 부(負)의 상관(相關)(r= -0.79, p<0.05)을 나타내어 주된 타감물질인 것으로 생각된다.

  • 목 적: 소아에서 혈액 및 종양질환 치료가 성장 및 신경정신기능에 미치는 영향을 알아보고자 본 연구를 시행하였다. 본 연구에서는 대조군을 일란성 쌍생아로 하여 여기에 영향을 주는 많은 인자들은 배제하였다. 방 법: 1995년 1월부터 2005년 6월까지 전남대학교병원 소아과에서 혈액 및 종양질환으로 치료받은 일란성 쌍생아 7명을 대상으로 하였다[급성 림프구성 백혈병, n=2; DBA, n=2; 중증 재생불량성 빈혈, n=3]. 이들의 진단 시 정중 연령은 5.2세(0.3-15세)이었고, 정중 관찰기간은 7.2년(4.9-10년)이었다. 대조군은 건강한 일란성 쌍생아 형제이었고, DBA를 가진 쌍생아는 1살 어린 동성의 동생을 대조군으로 사용하였다. 환자에게서 신장, 체중을 반복적으로 측정하여, 백분위수 통로를 평가하였다. 인지기능은 K-WISC III를 이용하였는데, 5쌍에서 비교가 가능하였다. 결 과: 성장은 환자와 건강한 쌍생아 간에 비슷한 양상을 보였다. 진단 시 3명의 환자에서 3-10 백분위수, 2명에서 25-50 백분위수, 그리고 나머지 2명에서는 50-75 백분위수를 보였다. 비만아가 된 1명을 제외하고 나머지 환자들은 추적관찰기간 동안 자신의 백분위수 통로를 유지하였다. IQ 검사 결과를 보면 행동성, 언어성, 전체 지능 지수의 평균치는 각각 88.0, 93.8과 89.8이었고, 대조군에서는 각각 92.2, 97.0과 91.8로 차이가 없었다. 하지만 급성 림프구성 백혈병으로 치료받은 두 명의 환아는 부분적 인지기능 저하가 나타났으며 그 중 방사선조사를 받은 환아에서는 인지기능 저하 외에도 심리적 장애인 주의력결핍 과다행동증후군이 나타났다. 결 론: 신장과 체중으로 본 성장은 환자나 일란성 쌍생아 형제나 비슷한 소견을 보였다. 환자의 IQ 지수는 쌍생아 대조군과 비슷하였다. 하지만 중추신경계 예방요법을 시행한 백혈병 환자에서는 IQ 지수가 낮아 질 수 있었다. 이러한 치료가 성장 및 정신신경 기능에 미치는 연관성을 정확히 알기 위해서는 더 많은 쌍생아에서의 전향적 연구가 필요할 것이다.

  • The purpose of this study was to identify the degree of sexual adjustment and quality of life in married men with spinal cord injuries and to furnish primary data to sexuality rehabilitation nursing practice which can lead to ideal sexual life and quality of life those men with SCI. Seventy married men with SCI were conveniently sampled in Kwangju, Suncheon, Mokpo and Seoul for responding the questionnaire, which was based on this research. With the research scale, SIS (Sexual interest and satisfaction) by Siosteen et al.(1990) and SB(Sexual behaviour) by Kreuter et al.(1996) were used for the measurement of sexual adjustment. And, for measuring quality of life was used SCI QL-23(Spinal cord injury of life-23) scale by Lundqvist et al.(1997). Data were collected from January 20 to March 20, 1999, using a structured questionnaire. A hundred volumes of questionnaire were used. and 85 volumes were collected, 70 volumes were used as research data after excluding 15 volumes unsuitable to data analysis. The obtain data were analysed using percentage, t-test, ANOVA, Duncan test, and Pearson's correlation by SAS PC+ program. The results were as follows: 1. The mean score of sexual interest and satisfaction of the subjects was 8.42. out of 18. The ways of their sexual behavior after spinal cord injuries were embracing and caressing (62.9%), kissing(58.6%), caressing breast with hands (55.7%), caressing breast with hands (52.9%), caressing genitals with hands (37.2%), caressing genitals with mouth(30.0%) and sexual intercourse (18.6%). The mean score of quality of life was 52.53 out of 100. 2. Age(F=3.24, p=.045) and caregiver (F=4.02, p=.022)were major variables which reveals significant differences in terms for sexual interest and satisfaction. The later results on Duncan's test showed that subjects who were in their 30s or 40s were significant higher than subjects whose age were in their 50s in their sexual interest and satisfaction. Also subjects with their spouse's care or mother's care were higher than those with other's care. 3. Subjects with incomplete paraplegia were higher than those with the complete paraplegia in sexual interest and satisfaction (F=3.01, p=.036). 4. Variables that showed the significant differences in the quality of life were education(t=2.860, p=.007) and period of marriage(t=2.125, p=.037). and occupational status(t=-2.161, p=.034). High school graduates, those who married before spinal cord injuries and those who didn't have occupation were higher than the other subjects. 5. Variables that revealed significant differences in the quality of life were time passage after spinal cord injuries(F=8.72, p=.001) and injured level of spinal cord(F=3.32, p=.042). Duncan's test showed that subjects who had lived for less than 4 years were higher those with time passage of 5-9 years and 10 years. Also subjects with lumbar injuries were higher than those with thoracic injuries in terms of quality of life. 6. There was negatively correlated between sexual interest and satisfaction and quality of life(r=-.256, p<.05). As a result of these findings sexuality rehabilitation for individuals with SCI was very important issue for their quality of life. Thus, registered nurses who care clients with SCI should activily participate in the client's sexual needs. Also, various sexual behaviors as well as sexual intercourse should be encouraged for the sexual adjustment of client's with SCI.

  • 본 연구는 회화자료의 분석을 통해 조선시대 취병의 특성과 제요소를 고찰한 것으로서 다음과 같은 결과를 도출하였다. 첫째, 조선시대 회화자료 25종에 대한 분석 결과, 취병은 주로 사생활 보호를 위한 차폐시설과 부지의 공간을 분할하는 구획시설로 기능하였으나, 내적으로는 정원에 품격과 아취를 부여하는 소품으로 설치되었다. 특히 취병 주변으로 학, 사슴등의 동물상 및 소나무, 파초, 대나무, 오동나무 등의 식물상과 괴석, 연못, 정자 등의 다양한 정원요소들이 나타났는데, 이것들은 이상적인 문인정원에 구비되어야 하는 일련의 조합으로 파악되었다. 둘째, 취병은 중국 고사(古事) 속 문인문화를 표상하는 관념적인 물상으로 인식되었다. 그러한 이미지는 고스란히 정원문화 속에 투영되었는데, '인물고사도 속 원림'을 모방 재현하는데 있어 취병은 중요한 경물로 사용되어 왔다. 셋째, 형태 기능 측면에서, 조선시대 회화 속에 나타난 취병들은 기본적으로 차폐 및 구획의 기능이 주요하였다. 사람 키를 웃도는 담장이나, 심지어 중국 대문 앞뒤에 설치되는 영벽의 높이까지 솟아 있기도 하여 공간적 필요에 따라 다양한 형태의 취병이 설치되었음을 알 수 있다. 넷째, 취병은 특정한 기능이나 입지상황 때문에 설치된 것보다는 당시 국내에 유행한 명대 문인문화의 유행과 밀접한 관련이 있다. 특히 중국에서 전해진 서원아집도 등에 나타난 취병의 도상은 한양을 중심으로 부유층의 저택에서 재현되었는데, 취병을 통해 부귀와 문인의 기상을 표현하려 했던 초기양식이 궁궐 및 상류층의 주택에서나 조성될 수 있는 고급 정원요소로 전화되었다. 또한 19세기 중엽 이후 취병의 활용은 평민의 주거양식으로 확산되는 이른바 저변화의 양상을 보였으며, 이는 취병이 토착화된 전개로 간주된다.

  • 본 연구는 우리나라의 고속도로 기본구간에서 기상조건에 따른 도시고속도로 교통류의 특성을 분석한 것이다. 본 연구의 주요 결과를 요약하면 다음과 같다. 첫째, 비가 올 경우 속도-교통류율간의 관계는 길어깨쪽 차로를 제외하고 차로별로 큰 차이가 없이 유사한 패턴을 보이는 것으로 나타났다. 둘째 교통류율-점유율간의 관계식은 비가 올 경우 그 관계성은 더 분명해지지만, 서비스교통류율이 약 200대/시/차로 정도 감소하는 것으로 나타났다. 셋째, 비가 올 경우 도로의 관측된 서비스교통류율은 맑은 날에 비해 약 10-20% 정도 감소하는 것으로 나타났으며, 이러한 결과는 1998 HCM에서 제시한 결과 및 교통류율-점유율 관계식의 기울기 감소 패턴과 일치한다. 넷째, 비가 올 경우 전체 차로의 소통능력은 맑은 날에 비해 감소하고 전반적으로 중앙분리대쪽 차로의 소통 능력이 길어깨쪽 차로에 비해 높은 것으로 나타났으나, 기상변화에 따른 차로별 임계속도와 임계점유율은 큰 변화가 없는 것으로 나타났다. 본 연구는 도시고속도로 기본구간의 1개 지점에서 나타난 특성으로서 공간적 분포 특성을 고려하기 위해서는 향후 연구에서 다양한 조건을 갖는 도로지점에 대해 분석해야 할 것이다. 또한 비 뿐만 아니라 안개나 눈에 의 한 영향을 고려한 상세한 분석이 필요하다. 본 연구의 결과는 그간 일반적으로 알려졌던 내용과 큰 차이는 없지만 실제로 고속도로를 설계하거나 운영하는데 근거자료로 활용할 수 있는 자료를 제공하는 측면에서 의미가 있다고 판단되며, 도로용량편람을 개정 및 수정하는 과정에서 명확히 명시해야할 기초자료를 제공하고 있다.Bayesian pooling technique for estimating the dynamic link travel time of networks.

  • The Sembilan Archipelago is famous for its great biodiversity, in which the humphead wrasse (Cheilinus undulatus) (locally named Napoleon fish) is the primary commodity (economically important), and currently, the environmental degradation occurs due to anthropogenic activities. This study aimed to examine the eco-environmental parameters and assess their influence on the abundance of humphead wrasse and other coral reef fish compositions in the Sembilan Archipelago. Direct field monitoring was performed using a visual census throughout an approximately one km transect. Coral cover data collection and assessment were also carried out. A coastal water quality index (CWQI) was used to assess the water quality status. Furthermore, statistical-based analyses [hierarchical clustering, Pearson's correlation, principal component analysis (PCA), and canonical correspondence analysis (CCA)] were performed to examine the correlation between eco-environmental parameters. The Napoleon fish was only found at stations 1 and 2, with a density of about 3.8 Ind/ha, aligning with the dominant composition of the family Serranidae (covering more than 15% of the total community) and coinciding with the higher coral mortality and lower reef fish abundance. The coral reef conditions were generally ideal for supporting marine life, with a living coral percentage of about > 50% in all stations. Based on CWQI, the study area is categorized as good and excellent water quality. Of the 60 parameter values examined, the phytoplankton abundance, Napoleon fish, and temperature are highly correlated, with a correlation coefficient value greater than 0.7, and statistically significant (F < 0.05). Although the adaptation of reef fish to water quality parameters varies greatly, the most influential parameters in shaping their composition in the study area are living corals, nitrites, ammonia, larval abundance, and temperature.

  • 본고에서는 1795년 화성 행궁에서 정조의 어머니 혜경궁 홍씨의 회갑을 맞아 열린 봉수당진찬의 의례와 악무를 "원행을묘정리의궤(園行乙卯整理儀軌)" 및 "정조실록", "홍재전서(弘齋全書)"등의 봉수당진찬 의례기록과 <화성능행도병>등의 도상자료, 일기체의 한글가사 작품인 이희평(李羲平)의 <화성일기(華城日記)>등의 자료를 중심으로 분석하여 무대와 공연요소 중심으로 고찰하였다. 잔치의 주인공에게 충(忠)과 효(孝)의 의미를 담은 음악과 춤, 꽃과 음식, 술과 글을 예를 갖춰 올리는 궁중연향은 예악(禮樂)의 원리에 바탕을 둔 국가의례로서 조선왕조 500년 동안 고유한 음악문화를 형성해왔다. 그러나 조선왕조가 막을 내리면서 '예'라는 상징적이며 총체적인 틀 안에서 상호 유기적인 관계에 놓여있던 연례의 음악과 춤들이 개별 악곡과 춤으로 해체되어 '작품화'되었고. 궁중음악과 춤의 철학이나 원리, 시공간에 대한 이해는 현저히 축소된 채, 음악과 춤의 전통은 형식과 예술적 표현 중심으로 변화해왔다. 1990년대 이후, 궁중의례 전통의 재현(再現)을 목적에 둔 연구와 행사가 추진되면서, 이와 연관된 공연예술 활동도 점차 증가하고 있는 추세이며, 특히 봉수당진찬은 다양한 방식으로 현대무대화 하고 있다. 그러나 원전(原典)의 재현(再現) 및 복원(復原) 문제, 완성도 및 예술성에 대한 문제는 과제로 남아있으며, 지금까지는 "원행을묘정리의궤"에 수록된 의주의 외형적 재현에 관심을 두었을 뿐, 무대조건이나 공연요소에 중점을 둔 심도있는 분석은 부족하였다고 판단하였다. 이에 본 연구에서 무대구성과 공연요소 중심으로 분석해 본 결과, 조선시대 궁중연향 중에서 유일하게 '행궁'에서 개최된 봉수당진찬은 '예악의 정치'를 의례와 악무로 구현하는 궁중연향의 기본적인 면모를 보여주면서도 '군신동락(君臣同樂)'의 친화의 비중이 높은 연향이었음을 밝혔다. 내연과 외연의 성격이 섞인 봉수당진찬에서는 가림막을 최소화하여 신분의 차서(次序)와 남녀유별(男女有別)의 원리를 충족시키면서도 삼면에 둘러친 휘장 안에 외빈의 자리를 마련함으로써 술과 음식, 음악과 춤을 다 같이 공유하도록 배치되었다. 또한, 연향공간의 상징성을 내포한 차일을 백관들의 공간에 치고, 임금이 솔선하여 선찬(膳饌)과 산화(散華)를 명함으로써 군신동연(君臣同宴)의 의미와 범위를 확장시킨 점을 알 수 있었다. 이는 봉수당진찬이 '예악의 원리'가 강하게 드러나는 여느 궁중 연향에 비해 '정(情)'을 나누는 화친(和親)에 기반을 두었음을 알 수 있었다. 또한, 봉수당진찬에서는 여느 내연에서보다 임금의 역할과 비중이 높았으며, 특히 의주 외의 기록으로 전하는 여러 가지 상황 - 7작 이후에 정조가 신하들을 가까이 불러 나눈 대화, 신하들에게 음식과 꽃을 내림, 잔치를 주제로 직접 시를 짓고, 신하들에게도 이에 화답하게 한 일 등-은 의주에 따른 단선적인 연향의 진행에 변화를 주고, 연향의 의미를 확장시키는데 한 몫 하였다. 이밖에, 봉수당진찬의 주악과 정재의 구성을 분석해 본결과 연향에서 여러 인물들의 대화와 움직임이 매우 절제된 것은 여느 궁중연향과 비슷하지만, 춤과 음악을 통해 구현된 소리와 색채감은 매우 다채로웠다는 점을 알 수 있었다. 봉수당진찬에서는 정조 이전에 치러진 내연에 비해 다양한 종류의 정재를 상연하였고, 이 중에는 새롭게 초연된 레퍼토리도 있었으며, 또 기존의 공연을 새롭게 재구성한 것도 포함되어 있었다. 특히 <선유락>이나 <검무> 등, 지방 관아 및 민간의 레퍼토리를 궁중연향으로 수용한 점, 풍류방에서 즐겨 연주되기 시작한 생황을 <학무> 와 연계한 것은 전통적인 규범과 관습에 매이지 않고 새로운 것을 받아들이는 궁중연향의 '열린구조'를 보여준다는 점에서 시사하는 바가 크다.

  • Today most developed countries provide modern medical care for most of the population. The rural area is the more neglected area in the medical and health field. In public health, the philosophy is that medical care for in maintenance of health is a basic right of man; it should not be discriminated against racial, environmental or financial situations. The deficiency of the medical care system, cultural bias, economic development, and ignorance of the residents about health care brought about the shortage of medical personnel and facilities on the rural areas. Moreover, medical students and physicians have been taught less about rural health care than about urban health care. Medical care, therefore, is insufficient in terms of health care personnel/and facilities in rural areas. Under such a situation, there is growing concern about the health problems among the rural population. The findings presented in this report are useful measures of the major health problems and even more important, as a guide to planning for improved medical care systems. It is hoped that findings from this study will be useful to those responsible for improving the delivery of health service for the rural population. Objectives: -to determine the health status of the residents in the rural areas. -to assess the rural population's needs in terms of health and medical care. -to make recommendations concerning improvement in the delivery of health and medical care for the rural population. Procedures: For the sampling design, the ideal would be to sample according to the proportion of the composition age-groups. As the health problems would be different by group, the sample was divided into 10 different age-groups. If the sample were allocated by proportion of composition of each age group, some age groups would be too small to estimate the health problem. The sample size of each age-group population was 100 people/age-groups. Personal interviews were conducted by specially trained medical students. The interviews dealt at length with current health status, medical care problems, utilization of medical services, medical cost paid for medical care and attitudes toward health. In addition, more information was gained from the public health field, including environmental sanitation, maternal and child health, family planning, tuberculosis control, and dental health. The sample Sample size was one fourth of total population: 1,438 The aged 10-14 years showed the largest number of 254 and the aged under one year was the smallest number of 81. Participation in examination Examination sessions usually were held in the morning every Tuesday, Wenesday, and Thursday for 3 hours at each session at the Namchun Health station. In general, the rate of participation in medical examination was low especially in ages between 10-19 years old. The highest rate of participation among are groups was the under one year age-group by 100 percent. The lowest use rate as low as 3% of those in the age-groups 10-19 years who are attending junior and senior high school in Taegu city so the time was not convenient for them to recieve examinations. Among the over 20 years old group, the rate of participation of female was higher than that of males. The results are as follows: A. Publie health problems Population: The number of pre-school age group who required child health was 724, among them infants numbered 96. Number of eligible women aged 15-44 years was 1,279, and women with husband who need maternal health numbered 700. The age-group of 65 years or older was 201 needed more health care and 65 of them had disabilities. (Table 2). Environmental sanitation: Seventy-nine percent of the residents relied upon well water as a primary source of dringking water. Ninety-three percent of the drinking water supply was rated as unfited quality for drinking. More than 90% of latrines were unhygienic, in structure design and sanitation (Table 15). Maternal and child health: Maternal health Average number of pregnancies of eligible women was 4 times. There was almost no pre- and post-natal care. Pregnancy wastage Still births was 33 per 1,000 live births. Spontaneous abortion was 156 per 1,000 live births. Induced abortion was 137 per 1,000 live births. Delivery condition More than 90 percent of deliveries were conducted at home. Attendants at last delivery were laymen by 76% and delivery without attendants was 14%. The rate of non-sterilized scissors as an instrument used to cut the umbilical cord was as high as 54% and of sickles was 14%. The rate of difficult delivery counted for 3%. Maternal death rate estimates about 35 per 10,000 live births. Child health Consultation rate for child health was almost non existant. In general, vaccination rate of children was low; vaccination rates for children aged 0-5 years with BCG and small pox were 34 and 28 percent respectively. The rate of vaccination with DPT and Polio were 23 and 25% respectively but the rate of the complete three injections were as low as 5 and 3% respectively. The number of dead children was 280 per 1,000 living children. Infants death rate was 45 per 1,000 live births (Table 16), Family planning: Approval rate of married women for family planning was as high as 86%. The rate of experiences of contraception in the past was 51%. The current rate of contraception was 37%. Willingness to use contraception in the future was as high as 86% (Table 17). Tuberculosis control: Number of registration patients at the health center currently was 25. The number indicates one eighth of estimate number of tuberculosis in the area. Number of discharged cases in the past accounted for 79 which showed 50% of active cases when discharged time. Rate of complete treatment among reasons of discharge in the past as low as 28%. There needs to be a follow up observation of the discharged cases (Table 18). Dental problems: More than 50% of the total population have at least one or more dental problems. (Table 19) B. Medical care problems Incidence rate: 1. In one month Incidence rate of medical care problems during one month was 19.6 percent. Among these health problems which required rest at home were 11.8 percent. The estimated number of patients in the total population is 1,206. The health problems reported most frequently in interviews during one month are: GI trouble, respiratory disease, neuralgia, skin disease, and communicable disease-in that order, The rate of health problems by age groups was highest in the 1-4 age group and in the 60 years or over age group, the lowest rate was the 10-14 year age group. In general, 0-29 year age group except the 1-4 year age group was low incidence rate. After 30 years old the rate of health problems increases gradually with aging. Eighty-three percent of health problems that occured during one month were solved by primary medical care procedures. Seventeen percent of health problems needed secondary care. Days rested at home because of illness during one month were 0.7 days per interviewee and 8days per patient and it accounts for 2,161 days for the total productive population in the area. (Table 20) 2. In a year The incidence rate of medical care problems during a year was 74.8%, among them health problems which required rest at home was 37 percent. Estimated number of patients in the total population during a year was 4,600. The health problems that occured most frequently among the interviewees during a year were: Cold (30%), GI trouble (18), respiratory disease (11), anemia (10), diarrhea (10), neuralgia (10), parasite disease (9), ENT (7), skin (7), headache (7), trauma (4), communicable disease (3), and circulatory disease (3) -in that order. The rate of health problems by age groups was highest in the infants group, thereafter the rate decreased gradually until the age 15-19 year age group which showed the lowest, and then the rate increased gradually with aging. Eighty-seven percent of health problems during a year were solved by primary medical care. Thirteen percent of them needed secondary medical care procedures. Days rested at home because of illness during a year were 16 days per interviewee and 44 days per patient and it accounted for 57,335 days lost among productive age group in the area (Table 21). Among those given medical examination, the conditions observed most frequently were respiratory disease, GI trouble, parasite disease, neuralgia, skin disease, trauma, tuberculosis, anemia, chronic obstructive lung disease, eye disorders-in that order (Table 22). The main health problems required secondary medical care are as fellows: (previous page). Utilization of medical care (treatment) The rate of treatment by various medical facilities for all health problems during one month was 73 percent. The rate of receiving of medical care of those who have health problems which required rest at home was 52% while the rate of those who have health problems which did not required rest was 61 percent (Table 23). The rate of receiving of medical care for all health problems during a year was 67 percent. The rate of receiving of medical care of those who have health problems which required rest at home was 82 percent while the rate of those who have health problems which did not required rest was as low as 53 percent (Table 24). Types of medical facilitied used were as follows: Hospital and clinics: 32-35% Herb clinics: 9-10% Drugstore: 53-58% Hospitalization Rate of hospitalization was 1.7% and the estimate number of hospitalizations among the total population during a year will be 107 persons (Table 25). Medical cost: Average medical cost per person during one month and a year were 171 and 2,800 won respectively. Average medical cost per patient during one month and a year were 1,109 and 3,740 won respectively. Average cost per household during a year was 15,800 won (Table 26, 27). Solution measures for health and medical care problems in rural area: A. Health problems which could be solved by paramedical workers such as nurses, midwives and aid nurses etc. are as follows: 1. Improvement of environmental sanitation 2. MCH except medical care problems 3. Family planning except surgical intervention 4. Tuberculosis control except diagnosis and prescription 5. Dental care except operational intervention 6. Health education for residents for improvement of utilization of medical facilities and early diagnosis etc. B. Medical care problems 1. Eighty-five percent of health problems could be solved by primary care procedures by general practitioners. 2. Fifteen percent of health problems need secondary medical procedures by a specialist. C. Medical cost Concidering the economic situation in rural area the amount of 2,062 won per residents during a year will be burdensome, so financial assistance is needed gorvernment to solve health and medical care problems for rural people.

  • The interplay between hedonic and utilitarian attributes has assumed special significance in recent years; it has been proposed that consumption offerings should be viewed as experiences that stimulate both cognitions and feelings rather than as mere products or services. This research builds on previous work on hedonic versus utilitarian benefits, regulatory focus theory, customer satisfaction to address two question: (1) Is the shopping goal at the point of purchase different from the shopping value? and (2) Is the customer loyalty after the use different from the shopping value and shopping goal? We surveyed 345 peoples those who have bought the electronic-goods within 6 months. This research dealt with the shopping value which is consisted of 2 types, hedonic and utilitarian. Those who pursue the hedonic shopping value may prefer the pleasure of purchasing experience to the product itself. They tend to prefer atmosphere, arousal of the shopping experience. Consistent with previous research, we use the term "hedonic" to refer to their aesthetic, experiential and enjoyment-related value. On the contrary, Those who pursue the utilitarian shopping value may prefer the reasonable buying. It may be more functional. Consistent with previous research, we use the term "utilitarian" to refer to the functional, instrumental, and practical value of consumption offerings. Holbrook(1999) notes that consumer value is an experience that results from the consumption of such benefits. In the context of cell phones for example, the phone's battery life and sound volume are utilitarian benefits, whereas aesthetic appeal from its shape and color are hedonic benefits. Likewise, in the case of a car, fuel economics and safety are utilitarian benefits whereas the sunroof and the luxurious interior are hedonic benefits. The shopping goals are consisted of the promotion focus goal and the prevention focus goal, based on the self-regulatory focus theory. The promotion focus is characterized into focusing ideal self because they are oriented to wishes and vision. The promotion focused individuals are tend to be more risk taking. They are more sensitive to hope and achievement. On the contrary, the prevention focused individuals are characterized into focusing the responsibilities because they are oriented to safety. The prevention focused individuals are tend to be more risk avoiding. We wanted to test the relation among the shopping value, shopping goal and customer loyalty. Customers show the positive or negative feelings comparing with the expectation level which customers have at the point of the purchase. If the result were bigger than the expectation, customers may feel positive feeling such as delight or satisfaction and they would want to share their feelings with other people. And they want to buy those products again in the future time. There is converging evidence that the types of goals consumers expect to be fulfilled by the utilitarian dimension of a product are different from those they seek from the hedonic dimension (Chernev 2004). Specifically, whereas consumers expect the fulfillment of product prevention goals on the utilitarian dimension, they expect the fulfillment of promotion goals on the hedonic dimension (Chernev 2004; Chitturi, Raghunathan, and Majahan 2007; Higgins 1997, 2001) According to the regulatory focus theory, prevention goals are those that ought to be met. Fulfillment of prevention goals in the context of product consumption eliminates or significantly reduces the probability of a painful experience, thus making consumers experience emotions that result from fulfillment of prevention goals such as confidence and securities. On the contrary, fulfillment of promotion goals are those that a person aspires to meet, such as "looking cool" or "being sophisticated." Fulfillment of promotion goals in the context of product consumption significantly increases the probability of a pleasurable experience, thus enabling consumers to experience emotions that result from the fulfillment of promotion goals. The proposed conceptual framework captures that the relationships among hedonic versus utilitarian shopping values and promotion versus prevention shopping goals respectively. An analysis of the consequence of the fulfillment and frustration of utilitarian and hedonic value is theoretically worthwhile. It is also substantively relevant because it helps predict post-consumption behavior such as the promotion versus prevention shopping goals orientation. Because our primary goal is to understand how the post consumption feelings influence the variable customer loyalty: word of mouth (Jacoby and Chestnut 1978). This research result is that the utilitarian shopping value gives the positive influence to both of the promotion and prevention goal. However the influence to the prevention goal is stronger. On the contrary, hedonic shopping value gives influence to the promotion focus goal only. Additionally, both of the promotion and prevention goal show the positive relation with customer loyalty. However, the positive relation with promotion goal and customer loyalty is much stronger. The promotion focus goal gives the influence to the customer loyalty. On the contrary, the prevention focus goal relates at the low level of relation with customer loyalty than that of the promotion goal. It could be explained that it is apt to get framed the compliment of people into 'gain-non gain' situation. As the result, for those who have the promotion focus are motivated to deliver their own feeling to other people eagerly. Conversely the prevention focused individual are more sensitive to the 'loss-non loss' situation. The research result is consistent with pre-existent researches. There is a conceptual parallel between necessities-needs-utilitarian benefits and luxuries-wants-hedonic benefits (Chernev 2004; Chitturi, Raghunathan and Majaha 2007; Higginns 1997; Kivetz and Simonson 2002b). In addition, Maslow's hierarchy of needs and the precedence principle contends luxuries-wants-hedonic benefits higher than necessities-needs-utilitarian benefits. Chitturi, Raghunathan and Majaha (2007) show that consumers are focused more on the utilitarian benefits than on the hedonic benefits of a product until their minimum expectation of fulfilling prevention goals are met. Furthermore, a utilitarian benefit is a promise of a certain level of functionality by the manufacturer or the retailer. When the promise is not fulfilled, customers blame the retailer and/or the manufacturer. When negative feelings are attributable to an entity, customers feel angry. However in the case of hedonic benefit, the customer, not the manufacturer, determines at the time of purchase whether the product is stylish and attractive. Under such circumstances, customers are more likely to blame themselves than the manufacturer if their friends do not find the product stylish and attractive. Therefore, not meeting minimum utilitarian expectations of functionality generates a much more intense negative feelings, such as anger than a less intense feeling such as disappointment or dissatisfactions. The additional multi group analysis of this research shows the same result. Those who are unsatisfactory customers who have the prevention focused goal shows higher relation with WOM, comparing with satisfactory customers. The research findings in this article could have significant implication for the personal selling fields to increase the effectiveness and the efficiency of the sales such that they can develop the sales presentation strategy for the customers. For those who are the hedonic customers may be apt to show more interest to the promotion goal. Therefore it may work to strengthen the design, style or new technology of the products to the hedonic customers. On the contrary for the utilitarian customers, it may work to strengthen the price competitiveness. On the basis of the result from our studies, we demonstrated a correspondence among hedonic versus utilitarian and promotion versus prevention goal, WOM. Similarly, we also found evidence of the moderator effects of satisfaction after use, between the prevention goal and WOM. Even though the prevention goal has the low level of relation to WOM, those who are not satisfied show higher relation to WOM. The relation between the prevention goal and WOM is significantly different according to the satisfaction versus unsatisfaction. In addition, improving the promotion emotions of cheerfulness and excitement and the prevention emotion of confidence and security will further improve customer loyalty. A related potential further research could be to examine whether hedonic versus utilitarian, promotion versus prevention goals improve customer loyalty for services as well. Under the budget and time constraints, designers and managers are often compelling to choose among various attributes. If there is no budget or time constraints, perhaps the best solution is to maximize both hedonic and utilitarian dimension of benefits. However, they have to make trad-off process between various attributes. For the designers and managers have to keep in mind that without hedonic benefit satisfaction of the product it may hard to lead the customers to the customer loyalty.

  • 발파(發破)에 있어서 천공배치(穿孔配置)는 발파효과에 영향(影響)을 미치는 가장 중요(重要)한 요소중(要素中)의 하나다. Burn-cut 의 폭발(爆發)의 여러 요소(要素)에 관(關)한 연구(硏究)는 Brown, Cook에 의(依)해 발표(發表)된 바 있으나 본연구(本硏究)에 있어서는 Burn-cut 와 Pyramid-cut의 천공배치(穿孔配置)의 대비(對比)와 폭원(爆源)과 자유면(自由面)사이의 역학적(力學的) 응력해석(應力解析)에 중점(重點)을 두어 이등교수(伊藤敎授)가 전개(展開)한 이론(理論)에서 다루지 않은 주정천공배치(週正穿孔配置)에 의(依)한 Burn-cut의 효과을 연결(連結)시켰다. 종래(從來)의 이론(理論)에 의(衣)하면 단일자유면발파(單一自由面發破)에 있어서는 압축응력외(壓縮應力外)에 자유면(自由面)에서 반사(反射)되는 인장응력(引張應力)의 영향(影響)을 추가(追加)로 받는다. 본(本) 신천공(新穿孔) 배치(配置)에 의(依)한 Burn-cut는 자유면수(自由面數)의 증가(增加)와 거리(距離)의 축소(縮少)를 꾀하므로서 이효과(效果)는 더욱 증대(增大)된다. 이와 같은 효과를 위(爲)해서는 다음 두가지 점(點)을 고려해야 한다. 첫째 심기공(心技孔)의 무장약공(無裝藥孔)은 보조응력(補助應力)을 크게 하기위(爲)해 가능(可能)한 대구경(大口徑)으로 깊게 천공(穿孔)해야 한다. 둘째 각 심기공간(心技孔間)의 거리(距離)를 접근(接近)시켜 완전(完全) 발파(發破)를 기(期)해야 한다. 그 까닭은 구경(口徑)이 증가(增加)됨에 따라 2차(次) 자유면(自由面)은 넓어지고 거리가 가까울수록 장약공(裝藥孔)과 무장약공(無裝藥孔)사이의 인장응력(引張應力)은 더욱 발달(發達)되기 때문이다. 선진국(先進國)에서는 심기공(心技孔)사이의 거리(距離)를 4"로 함이 이상적(理想的)이라고 알려지고 있으나 본실험(本實驗)에 의(依)하면 더 욱 근접(近接)될수록 파괴암석(破壞岩石)이 증가(增加)되고 굴진장(掘進長)도 깊어짐이 밝혀졌다. 나아가서는 굴진장(掘進長)을 더욱 증대(增大)시키기 위(爲)해 Burn-cut로 부터 Large hole Burn-cut를 개발(開發)하여 발파회수(發破回數) max 7회(回)/일(日)로서 1발파당(發破當) 3.1m까지 시도(試圖)함으로서 고속도굴진(高速度掘進)의 기원(起源)을 마련했다. 또한 대구경(大口徑) Burn-cut에서는 큰 저항(抵抗)을 극복하기 위해 금속초유폭약(金屬硝油爆藥)을 사용(使用)함이 더욱 효과적(效果的)임이 입증(立證)됐다. 최근(最近)에 와서 저렴(低廉)한 가격(價格)과 취급안전(取扱安全)으르 각광을 받고있는 AN-FO는 비료용 또는 공업용(工業用) 초안(硝安)에 연료유(燃料油)를 혼합(混合)한 것으로서 외관(雷管)만으로는 순감(純感)하여 폭발(爆發)하지 않으나 Gelatin Dynamite등(等)의 폭발성(爆發性) 예감제(銳感劑)에 의(依)해 발파공내(發破孔內)에서 일단 기폭(起爆)되면 종래(從來)의 초안폭약(硝安爆藥)에 상당(相當)한 위력(威力)을 발휘(發揮)케 한다. AN-FO 폭제(爆劑)의 성능(性能)에 관(關)해서는 많은 보고(報告)가 있었으나 본(本) 실험(實驗)에 의(依)하면 초유혼합비(硝油混合比)는 분상(粉狀)은 93.5:6.5, prill상(狀)은 94:6이 최적(最適)이며 분상(粉狀) AN-FO는 prill상(狀) AN-FO보다 항상(恒常) 폭속(爆速)이 높다. 또한 기폭감도(起爆感度), 충격감도(衝擊感度), 진거감도(塵據感度) 등(等) 제감도(諸感度)는 타화약(他火藥)에 비(比)해 몹시 경감(鏡感)하며 전폭성(傳爆性)은 prill상(狀)이 분상(粉狀)보다 우수(優秀)함을 얻었다. 발파후(發破後) Gas도 양호(良好)하며 AN-FO는 제조후(製造後) 7일(日) 전후(前後)가 최대효과를 갖는다. 종래(從來) AN-FO는 지난 여러해 동안 로천굴(露天掘)에만 사용(使用)하여 왔으나 필자(筆者)는 AN-FO의 기초성능시험(基礎性能試驗)을 토대(土臺)로 이를 이용(利用)한 신종폭제(新種爆劑)로서 금속초유폭약(金屬硝油爆藥)과 수중폭약(水中爆藥)을 발전(發展)시켰다. 금속초유(金屬硝油)의 폭약(爆藥)은 AN-FO와 Al 금속분말의 혼합물(混合物)이며 수중폭약(水中爆藥)은 종래폭약(從來爆藥)과 AN-FO로 제조(製造)한 바 이에 관(關)해서는 다른 논문(論文)에 기술(記述)했다. 본(本) 연구(硏究)에 있어서는 단일자유면(單一自由面) 발파(發破)에 있어서 격유폭약류(隔油爆藥類)를 사용(使用)한바 그 효과(效果)가 매우 양호(良好)하였음을 확인(確認)하였다.
