This, an association research for design-improvement and model-development of exhibition shops at rural tourism communities, is to secure objective data by analyzing customers' awareness-tendency of and demand for agricultural-specialty exhibition shops. Survey-questions for finding out consumers' awareness-tendency and demand were determined through brainstorming of a professional council, 30 rural communities of which visit-rate by consumers is considerably high were selected for the recruit of 200 consumers. For investigation and analysis, survey and in-depth interview were carried out at the scene with the application of frequency analysis and summarization of their opinions, which revealed that they have a strong will to visit the rural tourism communities for the purchase of agricultural specialties along with the experience of learning-program and on-the-scene direct dealing and that their viewpoint on the direct dealing at the scene was very positive. Also it was confirmed hat their satisfaction with the purchase of agricultural specialties by on-the-scene direct dealing, their pleasure at the purchase, their satisfaction with services and their intention for re-purchase of them were very high while their satisfaction with the exhibition shops was very low. With on-the-scene survey, the consumers' opinions could be listened to in depth. Almost all of them said their satisfaction with the trip to those rural tourism communities was considerably high since they could go to those communities themselves to relieve the stress from their modern life, to experience healing and to see the goods on the scene. Their satisfaction also was attributed to the fact that they have enough trust in purchase along with feeling the warm-heartedness of rural residents. As to their awareness of exhibition shops, they showed a positive response to the on-the-scene direct dealing at rural communities while they, thinking that the space in those exhibition shops was not sufficiently wide, demanded for more systematic counters in more accessible and affordable exhibition shops so that they might be more satisfied with the exhibition shops. Their demand for the necessity of exhibition shops selling agricultural specialties was found to be over 80%, which indicates that the necessity is very high. As to the suitability of function, they have the opinion that the business at those shops had better be focused on sales since they have the understanding of information when they take a trip to the rural communities, while there was another opinion: since agricultural products are seasonal items they should be exhibited and sold at the same time. More than 90% of the respondents had a positive viewpoint on direct dealing of agricultural specialties on the scene, which showed that their response to it was very high. They preferred the permanent shops equipped with roll-around table-booths. In addition, it was revealed that they want systematic exhibition shops in rural communities because they frequent those communities for on-the-scene direct purchase. The preferred type and opinion resulting from estimation of consumers' demands have been reflected for development of practical designs. The structure of variable principles has been designed so that the types of display-case and table-booth might be created. The result of this study is a positive data as a design model which can be utilized at rural communities and will be commercialized for the verification of its validity.

A review has been made of mortality trends in Korea from 1958 to 1967 analyzing the data by sex, age and cause of death. The crude death rates and age specific death rates were estimated by the model of N. Keyfitz life table which had been developed by the data of the 1960's national census. The cause specific death rates shown in this article are based on the following: all deaths occurring in the death-registration are expressed as a numberator, while the denominator was estimated from the regular national census data by interpolation method. It is estimated that only an average of about 40% of deaths which occurred during a year were registered during 1958 to 1967. The validity and the reliability of the diagnosis of causes of death seem to be extremely poor in this country. Therefore the cause specific death rates in this article are aimed to reveal trends of causes of registered death ana not for the actual level of death rates. For 10 years very interesing mortality trends were observed : 1. The trend in the crude death rates was downward slowly. 2. The estimated death rate for the infant in 1960 was still high up to 100 per 1,000. 3. The rates for mortality attributed to such infectious diseases as pneumonia, bronchitis, gastroenteritis and measles decreased an average 40-60%. 4. The death rates for over-all tuberculosis decreased only 9.8%. 90% of the decrease was contributed by those in the less-than-15 year age group. 5. The death rates for chronic diseases, such as vascular diseases affecting the central nervous system, malignant neoplasm, major heart diseases and all accidents rose about 40-60%. 6. The rank order of the 10 leading causes of death showed large changes over the years, except for pneumonia and tuberculosis which occupyed 1st and 2nd places respectively. Vascular diseases affecting the central nervous system moved from 5th to 3rd place and malignant neoplasm from 6th to 4th place, The major heart diseases moved from 10th to 6th place and all accidents from 10th to 7th place. On tile other hand, gastroenteritis moved from 3rd to 5th place and influenja from 4th to 8th place.

Purpose: The purpose of this study is to identify immunohistochemical evidence of lymph-node micrometastasis in histologic node-negative gastric cancer patients and to evaluate the prognostic significance of lymph-node micrometastasis.Materials and Methods: A retrospective study of 50 gastric cancer patients who underwent curative resections from October 1990 to November 1994 was performed. Two consecutive sections were prepared: one for ordinary hematoxylin and eosin staining, and the other for immunohistochemical staining with Pan cytokeratin antibody (Novocastra, UK). In the univariate analysis, the survival rate was calculated using the Life Table Method, and the multivariate analysis was determined using a Cox Proportional HazardsModel. The statistical analyses of the relationships between the clinicopathologic factors and micrometastases were performed by using a Chi-square test. Results: Of 2522 harvested lymph nodes, 81 ($4.1\%$) nodes and 19 ($38\%$) of 50 patients were identified as having lymphnode micrometastases by using immunohistochemical staining for cytokeratin. The incidence of lymph-node micrometastases was significantly higher in diffuse type carcinomas ($54\%$, P=0.024) and in patients with serosal invasion ($52.2\%$, P=0.05). For patients with lymph-node micrometastases (n=19), the 5-year survival rate was significantly decreased ($73.7\%$, P=0.015). The Lauren's classirication (P=0.021) and the depth of invasion (P=0.035) were shown by multivariate analysis to have a significant relationship with the presence of micrometastases. Multivariate analysis revealed that lymph-node micrometastasis was independently correlated with survival in histologic node-negative gastic cancer patients. Conclusion: The presence of cytokeratin detected lymphnode micrometastases correlates with the worse prognosis for patients with histologic node-negative gastric cancer.

This study is designed to facilitate the creation of home environment conducive to the family taking care of chronic bed-ridden patients with more effective method. The need for this study has emerged against the background of marked changes in the structure of ailments and causes of death, resulting in the number and plights of chronic bed-ridden patients as well as of a rapid increase in demand for medical care and resulting premature discharge. Keeping these in mind, this study focused on home-wards where the majority of chronic bed-ridden patients are being cared for. Despite. their overriding importance, home-words are less than efficient in caring (or chronic bed-ridden patients. These circumstances require the designing of home-wards that can offer greater comfort to patients and at the same time make things easier for caregivers, on the basis of an overall analysis of patients' life and home - ward situation. According1y this study adopted a Participant Observation Method derived cultural anthropology, Toward this end, 3 patients were chosen as subjects of this study for intensive interviewing and participant observation. In the process of this field re-search efforts were made to collect emprical data, that is, to faithfully record the words of the subjects and their caregivers for analysis and interpretation. The findings of these analyses are as follows. Firstly, the chronic bed-ridden patients are mostly being taken care by close family members. Secondly, a room for the exclusive use of the patient, floor, kitchen, bathroom and multipurpose space were found to be necessary for proper caring of the patient. These spaces were respectively used with a view to 1) accomodating the patient as well as caregivers' activities, 2) keeping general and medical supplies and other appliances for patient's care and drying the patient's washing, 3) preparing and keeping the patient's foods and beverages, 4) keeping the supplies necessary for cleaning the patient's body and treating the patient's eliminations, 5) washing the patient's clothes, underwears and bedclothes. The patient's room in turn is subdivided into six portions in terms of uses : specifically the places for accomodating 1) the patient, 2) medical supplies, 3) medicines, 4) linens St clothes, 5) bedclothes and, 6) diapers. Thirdly, the activities of the caregiver are subdivided into seven key areas : hygiene, exercise, diet, elimination, therapeutic nursing, prevention of sore, and other activities. Each area is further classified into several different activities of caring. These activities we mainly carried out in the patient's room. Fourthly, the supplies for caring the chronic bed-ridden patient is divided into two large domains : medical and general supplies. Finally, three main problems areas were found in this study on the part of caregivers, that is, sore prevention, hygiene problem related frequent urination / defecation, the caregiver's physical, psych ological and emotional burden. In consideration of the aforesaid problem areas, a model home-ward was developed in this study. The newly-developed model has been found to have the following six advantages. Firstly, the time and effort required for maintaining the patient's hygiene are reduced, thus relievins the caregiver's physical and psychological bur-den. Secondly, the patient's hygiene can be maintained in satisfactory conditions, because the patient's eliminations are more easily removed. Thirdly, skin irritations caused by the patient's eliminations were remarkably reduced and so were the patient's sores due to moisture and bacteria. Fourthly, the home-ward have a tilt-table ef-fect thanks to the inclining room floor. This improves the patient's cardiovascular function as well as constantly changes pressed skin areas and thus prevents sores. Fifthly, improved shelf arrangements help make the best use of patient's supplies. Sixthly, the trouble of continuously changing clothes, underwears, diapers & bedclothes is remarkably reduced simply by covering the patient with cotton sheets when laid in bed. This is espected to cut down expenses by reducing the comsumptions of diapers and other disposable supplies.

출산기술연구소 대관령지소에서 출생한 한우 암소로부터 시간적인 간격을 두고 조사된 체중측정 기록에 대해 비선형의 성장곡선 모형을 적용하여 한우 암소의 개체별 성장곡선 모수를 추정하고 개체별로 추정된 모수를 이용하여 한우 암소의 정확한 성장형태를 추정하기 위해 실시하였다. Gompertz 모형으로 추정한 개체별 성장 곡선 모수 A, b 및 k의 평균치는 각각 383.42${\pm}$97.29kg, 2.374${\pm}$0.340 및 0.0037${\pm}$0.0012였으며, 개체별 변곡점의 평균은 255.63${\pm}$109.09일, 변곡점에서 체중의 평균은 141.05${\pm}$35.79kg, 변곡점에서의 일당증체량의 평균은 0.500${\pm}$0.123 kg이었고, 성장곡선 모수 A, b 및 k의 변이계수는 각각 25.3, 14.3 및 32.4%이었다. von Bertalanffy 모형으로 추정한 개체별 성장곡선 모수 A, b 및 k의 평균치는 각각 410.47${\pm}$117.98kg, 0.575${\pm}$0.057 및 0.003${\pm}$0.001이었고, 개체별 변곡점의 평균은 211.02${\pm}$105.53일, 변곡점에서 체중의 평균은 121.62${\pm}$34.94kg, 최대 증체율의 평균은 0.504${\pm}$0.124kg이었으며, 성장곡선 모수 A, b 및 k의 변이계수는 각각 28.7, 9.9 및 33.3%로 추정되었다. Logistic 모형으로 추정한 개체별 성장곡선 모수 A, b 및 k의 평균치는 각각 347.64${\pm}$97.29kg, 6.73${\pm}$0.34 및 0.006${\pm}$0.0018이었고, 개체별 변곡점의 평균은 324.47${\pm}$3.87일, 변곡점에서 체중의 평균은 173.82${\pm}$1.13kg, 최대 증체율의 평균은 0.508${\pm}$0.003kg이었으며, 성장곡선 모수 A, b 및 k의 변이계수는 각각 27.9, 5.0 및 30.0%이었다. Gompertz 모형, von Bertalanffy 모형 및 Logistic 모형에 의해 추정된 생시체중의 평균치들은 각각 36.40${\pm}$0.33, 31.59${\pm}$0.34 및 49.09${\pm}$0.88kg으로 추정되어 실제체중 23.73${\pm}$0.10kg 보다 컸으며 36개월 체중의 경우 세 모형이 각각 349.73${\pm}$2.01, 356.41${\pm}$2.07 및 336.18${\pm}$1.91kg으로 실제체중 363.67${\pm}$2.08kg보다 작았다. 그러나 세 모형으로 추정된 변곡점이 한우 암소의 실질적인 변곡점인지에 대해서는 좀더 검토가 필요한 부분인데, 최(2001)는 한우 암소의 경우 3개월령에서 4개월령 사이의 일당증체량이 0.590으로서 이 시기에 최대의 성장이 이루어지며 3개월령 체중과 4개월령 체중은 각각 79.31 및 98.91kg이라고 보고하고 있으며, 본 연구에서 Table 4에 제시된 결과를 봐도 3개월령과 6개월령 사이 90일 동안에 50.89kg의 증체가 이루어져 일당증체량으로 환산하면 약 0.56kg이 되어 다른 어느 시기보다도 가장 증체속도가 빠른 시기인 것으로 나타났다. 변곡점이 일당증체량이 최대인 시점으로 해석한다면 각 모형에서 고정되어 있는 변곡점의 위치들인 성숙체중의 38.6%(Gompertz 모형), 29.6% (von Bertalanffy 모형) 및 50%(Logistic 모형)는 한우 암소의 실질적인 변곡점보다 늦는 것으로 판단할 수 있는데, 실제로 세 모형 중 변곡점의 위치가 제일 빠른 von Bertalanffy 모형의 적합도가 제일 좋은 것도 이러한 이유 때문일 수 있다. 따라서 한우 암소의 정확한 성장특성을 파악하기 위해서는 변곡점의 위치가 고정되어 있지 않은 기존의 모형들을 이용하는 방안과 아울러 본 연구에 이용된 모형들을 변형시켜 활용하는 방안에 대한 연구가 필요한 것으로 판단된다.

목 적: 소아 만성 B형간염의 치료제로 interferonalpha(IFN)가 널리 이용되어 왔으며 약 30~40%에서 치료효과가 나타나는 것으로 보고되어 왔다. 그러나 우리나라에서 소아를 대상으로 IFN 치료를 시행한 후 장기 추적관찰을 통한 연구는 충분히 이루어지지 않은 상태로, 본 연구에서는 소아 만성 B형간염에서의 IFN 치료 효과와 그에 영향을 미치는 요인들을 장기 추적하여 분석하고자 하였다. 방 법: 1982년 5월부터 2002년 7월까지 약 20년 동안 연세의대 세브란스병원 소아과에 내원하여 HBsAg, HBeAg 및 HBV-DNA가 6개월 이상 양성 소견을 보여 만성 B형간염으로 진단받은 환아 378 명 중 IFN 치료를 시행받은 113명을 대상으로 하였으며, 남녀 비는 2.3 : 1이었고, 진단 당시의 평균 연령은 $11.1{\pm}4.1$세이었다. IFN은 300만 unit를 주 3회 근육 주사하였으며, 주기적으로 외래에서 B형 간염 표지자와 간기능검사를 시행하였다. 치료받은 환아는 4~114개월($48.1{\pm}33.4$개월) 동안 추적 관찰하였으며, IFN 치료 후 재발한 경우는 lamivudine 또는 IFN 재치료를 시행하였다. 결 과: IFN 치료에 대한 반응은 HBeAg과 HBV-DNA의 음전 및 ALT값의 정상화로 정의하였으며 반응군은 82례(72.6%), 비반응군은 32례(28.3%)로 두 군 간에 임상적으로 유의한 차이는 없었다. IFN 치료 후 HBeAg은 총 113례 중 87례(77%)에서 음전 되었고, anti-HBe는 79례(70%)에서 양전, HBV-DNA는 84례(74.3%)에서 음전되었다. HBeAg, HBV-DNA 모두 음전 된 환아는 82례(72.6%), HBV-DNA 만 음전된 환아는 2례(1.8%)였으며, HBeAg만 음전된 환아는 5례(4.4%)였다. HBsAg은 6례(5.3%)에서 음전, anti-HBs는 11례(9.7%)에서 양전되었다. ALT 값은 91례(80.5)에서 정상화되었다. IFN 치료 후 HBeAg 및 anti-HBe, HBV-DNA, HBsAg 및 anti-HBs의 음전 및 양전이 일어나는 기간을 생명표를 이용하여 통계 분석한 결과 HBeAg의 5년 음전율은 78%, 10년 음전율은 90%로 최고조를 보였으며, anti-HBe는 5년 양전율이 77%, 10년 양전율이 84%로 최고조를 보였다. 또한 치료 후 HBV-DNA의 5년 음전율은 80%였고, 10년 음전율은 88%로 최고조를 이루었다. 또한 HBsAg의 음전율과 anti-HBs 의 양전율은 5년 후 각각 6.7% 및 13%로 최고조를 이룬 후 계속 추적 관찰하는 동안 변화가 없었다. IFN 치료 후 HBeAg의 음전 및 anti-HBe의 양전은 각각 평균 $14.1{\pm}17.0$개월 및 $16.1{\pm}17.7$개월 걸렸고, HBV-DNA의 음전은 평균 $14.2{\pm}14.1$개월이 소요되었다. HBsAg은 단지 5%의 환아에서만 음전되었으며 평균 $14.2{\pm}12.1$개월이 걸렸다. 치료 후 혈청 ALT값이 정상화 되는 데는 평균 $11.1{\pm}14.4$개월이 걸렸다. 시간의 경과에 따른 치료 전 혈청 ALT값, HBV-DNA값, 치료 전 환아의 연령이 B형 간염 표지자의 반응에 미치는 영향을 Cox model로 분석한 결과, 치료 전 ALT값이 높을수록 HBV-DNA가 통계학적으로 가장 의미 있게 음전되었다(p=0.027). HBeAg과 anti-HBe는 통계학적으로 의미는 없었으나 치료 전 혈청 ALT값이 높을수록 음전(p=0.18) 및 양전(p=0.079)이 증가되는 경향을 보였다. 기타 치료 전 혈청 HBV-DNA값과 연령은 B형간염 표지자의 반응에 미치는 영향은 통계학적으로 의미가 없었다. IFN 치료 후 총 82례의 반응군 중 11례(13.4%)에서 재발하였다. 이중 3례에서 lamivudine 치료를 시행하였으며, 2례에서 치료에 반응하였다. 3례에서는 IFN를 재치료하여 이 중 1례에서 치료 효과가 있었으며, 나머지 3례는 특별한 치료 없이 표지자들이 혈청변환(seroconversion)되었다. IFN 치료에 반응을 보이지 않거나 재발된 총 9례에서 lamivudine 치료를 시행하였으며, 이 중 3례(33%)에서 혈청변환이 있었다. 결 론: 소아 만성 B형간염에 대한 IFN의 치료효과를 10년간 장기 추적한 결과 B형간염 표지자의 혈청 변환율이 72.6%로 높은 치료 반응률을 보이고, 또한 재발률이 13.4%로 비교적 낮은 훌륭한 치료제로 확인되었다. 그러나 HBsAg 음전율은 5.3%에 불과하기 때문에 향후 IFN 치료가 소아 만성 B형간염의 간질환 합병증, 간세포암 발생률 및 생존율에 미치는 영향에 대한 장기적인 연구가 필요할 것으로 사료된다.
