This study set out to investigate the relations between middle school students' perception of body image and their allowance for plastic surgery, to understand their perception of body image and desire for plastic surgery, and provide some data needed to warn against reckless plastic surgery and guide the students effectively. For those purposes, an examination was conducted of the relationships between the individual characteristics and perception levels of body image, the individual characteristics and allowance for plastic surgery, and perception levels of body image and allowance for plastic surgery. The subjects were drawn from sour middle schools located in two regions of Gyeonggi Province. Total 922 boys and girls were surveyed on a questionnaire, which was developed based on the pretest of previous literature, reviewed for appropriateness, and tested for reliability and reasonableness. The body image on the five scale was greater as the perception level was higher. The allowance for plastic surgery was also greater as the scores were more. The findings were as follows: First, the relationships between individual characteristics and perception levels of body image were examined. The third graders showed the highest perception level, being followed by the first and second graders. The girls were more perceptive than the boys, and those who were extrovert were more perceptive than those who were introvert. Those students whose parents earned 2 million won or more a month and who adapted themselves to the environmental changes had a higher perception level. In a word, the girls from the middle class that were well adapted, felt happy, and were extrovert had a higher perception level of body image. Second, the connections between individual characteristics and allowance for plastic surgery were investigated. The third graders were the most admissive of plastic surgery, followed by the second and first graders. That is, the upper graders were more admissive of plastic surgery. In addition, the girls were more admissive than the boys, and those who were extrovert were more than those who were introvert. There were no significant differences according to the monthly income of the parents, grades, adaptability to surroundings, and happiness, which results almost resembled the findings of a study conducted on adults. Third, there were negative correlations found between the perception levels of body image and the allowance for plastic surgery. To elaborate, the higher the perception levels were, the lower the allowance was, and vice versa. As for the items, the subjects showed more allowance for plastic surgery when they scored less in the item of caring about appearance, importance of looking pretty to others, and efforts to improve appearance. When they had a low value of body and easily felt tired, they were highly acceptive of plastic surgery. The allowance for plastic surgery was also great when their perception was much of how healthy they felt, how important they felt about their bodies, how they were satisfied with their current appearances, how they evaluated the appearance of others, how much they were satisfied physically, and how much demanding they were for physical changes. Meanwhile, there were no correlations between the allowance and physical attraction, the degree for one's activities to be hindered, and sickness. In short, the demand for plastic surgery was 41% for the girls and 20.2% for the boys. Just as the study on adults reported, those who had a low or negative perception of body image were more acceptive of plastic surgery. The middle school students were generally positive about their bodies with the lowest perception level at 2.91 and the highest at 3.21. Their individual allowance for plastic surgery was related to their individual body images, which were in turn affected by the mass communication, surrounding environments, and social values. Thus it's necessary for the entire society to try to improve or change the overall perception. Helping measures should be taken so that the students can form right sense of values about their bodies, avoid the obsession with appearance and appearance-based evaluation, and exercise righteous criteria against humans beings and things. In conclusions, the following suggestions were made: they need to develop such questionnaires or tools as can measure the body image of teens and fit the reality. Moreover, body image improvement programs should be more diverse and more applicable to teens. Despite the consistent reports that prove the correlations between body image and plastic surgery, there has been little effort to apply such factors as experience of the life of the disabled, volunteer activities for the disabled and at the hospitals, and others that can induce changes to body image to the body image improvement programs. In the future, comparative research should be carried out on body image and plastic surgery.

It has been believed that cancer is an omnious factor threatening the future and life itself. Patients having the disease experience anxiety, fear, feeling of weakness, depression and feelings of uncertainty and hopelessness. Most cancer patients, however, have expectations of possible recovery and a better future, very different from the patients who feel hopeless. Therefore. hope allows people to respond effectively to the fatal disease they have and prevents them from detoriorating physically and spiritually, positively influencing their survival, response to treatment and sense of security. Studies previously performed showed that hope is positively correlated with social and family supports, self-esteem, spiritual well-being, responsive action, health promotion behavior and quality of life. Thus, the study attempted to provide basic information on nursing cancer patients by investigating their levels of hope and determining predictive factors which influence hope. For the study 200 cancer patients in two university hospitals located in Pusan were sampled as subjects. Data were collected for twenty nine days from Feburary 1, 1999 to March 1. Instrumets for the study included 10 items from the self-esteem scale by Rosenberg (1965), 39 hope measurements by Kim and Lee(1965), 16 of the social support scale by Tae(1986) and 16 of the general characteristics scale, all of which totaled 81 items. The data were analyzed using the SPSS program. General characteristics of the investigated based on numbers and percentage. Hope, self-esteem and social support were analyzed using means, minimum, maximum and standard deviation. Relations among the foregoing three factors were analyzed using Pearson' correlation coefficient. Levels of hope in cancer patients were determined using t-test, ANOVA and Scheffe test. Predictive factors influencing hope were investigated using multiple stepwise regression analysis. Results of the study are summarized as follows: 1. An average level of hope was $185.55{\pm}23.39$ points(96 min. and 234 max.) 2. Levels of hope showed a significant difference among them according to sex (t=-3.69, P=.000), age(F=4.714, P=.000), job(F=3.247, P=.008), monthly income (F=6.113, P=.003), treatment charge (F=3.796, P=.011), supportive resources (F=10.554, P=.000), diagnosis(F=2.287, P=.029), perceived health status(F=22.184, P=.000), level of pain(F=3.334, P=.021), religion (F=4.911, P=.001) and religion's effect in life (F=11.706, P=.000), 3. For the subjects, self-esteem and social support were $38.32{\pm}7.21$(13 min, and 50 max.) and $52.97{\pm}8.49$points(28 min, 80 max.). Concerning social support, average levels of family support and medical support were found $35.95{\pm}6.05$(18 min, and 40 max) and $27.02{\pm}4.99$ points(20 min and 40 max). The hope the cancer patients showed significant correlations with self-esteem (r=.588, P=.000), family support(r=.224, p=.001) and medical support(r=.221, P=.002). 4. The five variables related to hope (self-esteem, religion's effect in life, perceived health status, social support and age) accounted for 54.2 percent of the hope level; especially, self-esteem was the highest at 34.6%. As shown in the above results, predictive factors which most influence hope in cancer patients were self-esteem and religion's effect of life. Therefore, nursing interventions to increase self-esteem should be developed. Regarding religion's effects, studies on spiritual aspects should be carried out in a way that contributes to promotion of hope.

결정질 암반내에 발달하는 단열은 지하수유동의 주요 경로가 되므로, 유동성 단열의 특성 규명은 유동체계를 해석하는데 매우 중요하다. 암반 내 단열 중 유동성 단열을 추출하기 위해 편마암 지역내 폐광산을 대상으로 단열특성을 파악했다. 연구지역내 지표 노두와 항내에 발달하는 단열 중, 단층은 방향성, 단층폭, 연장성, 운동감각, 충전물질, 절리의 경우는 방향성, 길이, 간격, 틈(aperture), 충전물질, 조도(roughness), 타 절리들과의 교차 및 연결성을 조사했다. 한편, 지표 하에 발달하는 단열특성 파악을 위해 연구지역내 5개 지점에 시추를 실시하여 이를 통해 회수된 코아시료를 정밀 로깅했다. 그 중, 3개 시추공을 대상으로 초음파주사검층을 실시하여 단열의 방향성과 단열종류를 구분하고 획득한 자료를 처리.분석하였다. 조사결과에 따르면 지표상에 발달하는 대표 단열군은 GSet 1: N50-82$^{\circ}$E/55-90$^{\circ}$SE, GSet 2: N2-8$^{\circ}$E/56-86$^{\circ}$SE, GSet 3: N46-72$^{\circ}$W/60-85$^{\circ}$NE, GSet 4:Nl2-38$^{\circ}$W/15-40$^{\circ}$SW 단열군으로 나타났다. 이에 대응되는 지표하 단열군은 HSet 1: N50-90$^{\circ}$E/55-90$^{\circ}$SE, HSet 2: N10-30$^{\circ}$E/50-70$^{\circ}$SE, HSet 3: N20-60$^{\circ}$W/50-80$^{\circ}$NE, HSet 4: N10-50$^{\circ}$E/$\leq$40$^{\circ}$NW로 분류되었다. 이 단열군들 중 GSet 1 및 GSet 3, 그리고 HSet 1 및 HSet 3은 연구지역내 가장 우세하게 발달하는 단열군이다. HSet 1은 평균 단열간격이 30~47 m이며, 이 단열 중 등급(code) 1 단열(단층, 열린단열) 등이 21.0~42.9%를 구성한다. HSet 3은 55~57 cm의 평균 단열간격을 보이고, 등급 1 단열이 15.4~26.9%를 차지한다. HSet 4는 239 cm의 평균 단열간격을 보여 연구지역내 우세 단열군 중 가장 넓은 단열간격을 가지나, 등급 1 단열의 비율이 54.5%에 이른다. 등급 1 단열과 유사한 특성을 갖는 단층이나 열린단열은 다른 성질의 단열에 비해 상대적으로 수리전도성이 큰 것으로 알려져 있음을 통해, N55-85$^{\circ}$E/50-80$^{\circ}$SE 단열군과 N20-60$^{\circ}$W/50-75$^{\circ}$NE 단열군, 그리고 N10-30$^{\circ}$E/$\leq$30$^{\circ}$NW 단열군이 연구지역 내에서 지하수 유동성이 가장 높은 단열군으로 추정된다. 이러한 사실은 3개 시추공을 대상으로 실시한 시추공 내 물리검층과 정압주입시험에서도 확인된다.

폐기물 및 기타물질의 투기로 인한 해양오염을 방지하기 위해 1972년 정부간 회의에서 런던협약이 체결되었고 1996년 국제해사기구 본부에서 개최된 특별회의에서는 폐기물 처리 처분 기술과 해양환경에 대한 인식의 변화를 반영하여 동 협약을 전면 개정해 런던의정서를 채택하였다. 런던의정서는 런던협약보다 구체적으로 해양투기 관리 체제를 마련하고 조약의 법적 실효성을 확보하기 위해 준수절차와 메커니즘을 채택하도록 하고 있다. 동 의정서는 2006년 3월에 발효되었으며 2007년에는 준수절차와 메커니즘을 채택하고 준수그룹이 설치되었다. 런던의정서 준수그룹은 유엔 지역그룹 별로 선출된 각 3명의 위원들로 구성되며 우리나라는 2009년 10월에 아시아 지역 국가들의 동의를 얻어 준수위원을 배출하였다. 지리적 정치적으로 동일한 정체성을 지니는 지역그룹체제의 도입으로 런던의정서 당사국들은 의정서 관련 회의들에서 지역그룹별 투표 블록을 형성하거나 정보 교환 등을 할 수 있을 것으로 전망된다. 서유럽 및 기타 국가 그룹의 국가들로 구성된 북동대서양해양환경보호조약 (OSPAR)에서 1992년에 채택한 심의 허용 품목 이외의 포괄적 투기 금지 방식을 런던의정서에서 도입한 사례는 이러한 측면에서 주목할 만하다. 특히 런던의정서는 최근에 모든 오염원으로부터 해양환경을 보호하는 방향으로 물적, 인적 관할범위를 확대하고 있으며, 이에 따라 지역그룹의 역할은 더욱 중요하게 될 것이다. 따라서 본 소고에서는 유엔 지역그룹체제의 성격을 파악하고 런던의정서 회의들에서 지역그룹체제의 영향에 대한 검토를 통해 향후 우리나라의 대응방안을 제시하고자 한다.

Purpose: FLAIR image is beneficial for the diagnosis of various bran diseases including ischemic CVS, brain tumors and infections. However the border between the legion of brain metastasis and surrounding edema may not be clear. Therefore, this study aims to investigate the practical benefits of delayed imaging by comparing the image from a patient with brain metastasis before a contrast enhancement and the image 10 minutes after a contrast enhancement. Materials and methods: Of the 92 people who underwent MRI brain metastases in suspected patients 13 people in three patients there is no video to target the 37 people confirmed cases, and motion artifacts brain metastases in our hospital June-December 2013, 18 people measurement position except for the three incorrect patient (male: 11 people, female: 7 people, average age: 60 years) in the target, test equipment, 3.0T MR System (ACHIEVA Release, Philips, I was 8ChannelSENSE Head Coil use Best, and the Netherlands). TR 11000 ms, TE 125 ms, TI2800 ms, Slice Thickness 5 mm, gap 5 mm, is a Slice number 21, the parameters of the 3D FFE, T2 FLAIR variable that was used to test, TR 8.1 ms, TE 3.7 ms, Slice number 240 I set to. The experiment was conducted by acquiring the FLAIR prior to contrast enhancement (heretofore referred to as Pre FLAIR), and acquiring the 3D FFE CE five minutes after the contrast enhancement, and recomposing the images in an axial plane of S/T 3mm, G 0mm (heretofore referred to as MPR TRA CE). Using the FLAIR 10 minutes after the contrast enhancement (heretofore referred to as Post FLAIR) and Pi-View, a retrospective study was conducted. Using MRIcro on the image of a patient confirmed for his diagnosis, the images before and after the contrast media, as well as the CNR and SNR of the MPR TRA CE images of the lesion and the site absent of lesion were compared and analyzed using a one-way analysis of variance. Results: CNR for Pre FLAIR and Post FLAIR were 34.35 and 60.13, respectively, with MPR TRA CE at 23.77 showing no significant difference (p<0.050). Post-experiment analysis shows a difference between Pre FLAIR and Post FLAIR in terms of CNR (p<0.050), but no difference in CNR between Post FLAIR and MPR TRA CE (p>0.050), indicating that the contrast media had an effect only on Pre FLAIR and Post FLAIR. The SNR for the normal site Pre FLAIR was 106.43, and for the lesion site 140.79. Post FLAIR for the normal site was 107.79, and for the lesion site 167.91. MPR TRA CE for the normal site was 140.23 and for the lesion site 183.19, showing significant difference (p<0.050), and post-experiment analysis shows that there was a difference in SNR only on the lesion sites for Pre FLAIR and Post FLAIR (p<0.050). There was no difference in SNR between the normal site and lesion site for Post FLAIR and MPR TRA CE, indicating no effect from the contrast media (p>0.050). Conclusions: This experiment shows that Post FLAIR has a higher contrast than Pre FLAIR, and a higher SNR for lesions, It was not not statistically significant and MPR TRA CE but CNR came out high. Inspection of post-contrast which is used in a high magnetic field is frequently used images of 3D T1 but, since the signal of the contrast medium and the blood flow is included, this method can be diagnostic accuracy is reduced, it is believed that when used in combination with Post FLAIR, and that can provide video information added to the diagnosis of brain metastases.

모든 디자인 행위의 근본은 인간의 가장 바람직한 삶을 위해 헌신함으로써 풍요로운 생활을 실현시키는데 그 목적이 있다. 여기에 디자인의 참뜻이 숨어 있고, 또한 이것은 디자인이 인간의 가치 있는 삶을 위해 매진해야 한다는 뚜렷한 반증이기도 하다. 이러한 관점에서 볼 때 모든 디자인에 대한 논란은 어떻게 가치 있는 디자인을 창출할 수 있느냐에 그 관심이 집중된다. 한편 고도로 발전된 정보사업 사회에서 우수한 제품의 개발을 촉진할 수 있는 디자인이 기업의 성패를 좌우한다는 것은 이미 상식이 되어 있다. 그러나 디자인이 추구하는 가치는 생존을 위한 도구를 창출하는 것이다. 따라서 이와 같은 도구창조 행위가 모든 디자인 가치창출의 근본적인 배경이 된다는 것에 대해서는 재론의 여지가 없다. 이러한 사실은 모든 디자인이 자연원리에 기반을 둔 바이오 디자인(bio-design)을 철저히 연구해야 만 보다 나은 디자인을 창출할 수 있다는 것을 의미한다. 왜냐하면 자연은 모든 디자인의 원초적인 모델이며 자연의 원리는 모든 디자인 원리의 모태가 되기 때문이다. 특히, 오늘날 디자인은 하이테크(hi-tech)를 더욱 중요시하고 있다. 또한 지역적인 특성에서 발생되는 여러 가지 문제점을 파악하고 고유한 문화적인 아이덴티티를 가미하지 않으면 성공적인 디자인을 기대하기는 어렵다. 다시 말해서 디자인은 더욱 다양화되고 특성화되기 때문에 휴먼터치(human-touch)를 근간으로 한 바이오 디자인은 날로 그 중요성을 더해가고 있다. 이와 같은 상황에서 디자인의 본질적인 가치를 파악하고 실제적인 응용방법을 모색하여 시대상황의 변화에 대처할 수 있는 디자인이 새로운 가치를 창출할 수 있는 근간을 마련하는 것은 매우 유익한 일일 것이다.서 주변 관련 분야들의 접근 방법을 분석하여 사용자의 특성과 행위에 대한 다각적인 해석 방법을 탐색하여 (1) 물리적 환경 요소 분석- 사용자의 공간에 대한 물리적 감각을 토대로 하는 건축의 규모와 비례의 상관성 분석 접근 방법 (2) 사용자의 욕구와 필요에 의해 한 공간의 의미 결정 요소- 형태 언어를 표집 분석 접근 방법 (3) 인간의 행동 요소- 형태 반응 분석 접근 방법을 선택 조사하여 이를 통해 디자인 프로세스에 있어서 관련 분야와의 합리적 접합 통로를 마련하고 이를 활용, 설정된 목적에 도달하는 협동 작업의 체계화를 제안하였다.류의 유기 염소계 잔류 농약이 sharp하게 검출되었고 높은 감도를 나타내었다).미치는 영향을 종합적으로 분석하였다.ine은 다른 성분(成分)들과 비교(比較)해 볼 때 가장 높은 조성(組成)의 차이(差異)를 나타내었다. 7. 야생(野生)더덕과 재배(栽培)더덕의 정유성분수율(精油成分收率)은 자생지재배(自生地栽培)에서는 모두 0.004% 였고 재배지(栽培地)에서는 야생(野生)더덕이 0.005%였다. 8. 더덕의 재배장소(栽培場所)에 따른 향기성분(香氣成分)은 총(總) 21종(種)이었으며 自生地(自生地)에서 야생(野生)더덕은 16종(種), 재배(栽培)더덕은 18종(種)이었고, 재배지(栽培地)에서 야생(野生) 더덕은 14종(種), 재배(栽培)더덕은 20(種)이었다. 9.

Information systems (IS) have become ubiquitous and changed every aspect of how people live their lives. While some IS have been successfully adopted and widely used, others have failed to be adopted and crowded out in spite of remarkable progress in technologies. Both the technology acceptance model (TAM) and the IS Success Model (ISSM), among many others, have contributed to explain the reasons of success as well as failure in IS adoption and usage. While the TAM suggests that intention to use and perceived usefulness lead to actual IS usage, the ISSM indicates that information quality, system quality, and service quality affect IS usage and user satisfaction. Upon literature review, however, we found a significant void in theoretical development and its applications that employ either of the two models, and we raise research questions. First of all, in spite of the causal relationship between intention to use and actual usage, in most previous studies, only intention to use was employed as a dependent variable without overt explaining its relationship with actual usage. Moreover, even in a few studies that employed actual IS usage as a dependent variable, the degree of actual usage was measured based on users' perceptual responses to survey questionnaires. However, the measurement of actual usage based on survey responses might not be 'actual' usage in a strict sense that responders' perception may be distorted due to their selective perceptions or stereotypes. By the same token, the degree of system quality that IS users perceive might not be 'real' quality as well. This study seeks to fill this void by measuring the variables of actual usage and system quality using 'fact' data such as system logs and specifications of users' information and communications technology (ICT) devices. More specifically, we propose an integrated research model that bring together the TAM and the ISSM. The integrated model is composed of both the variables that are to be measured using fact as well as survey data. By employing the integrated model, we expect to reveal the difference between real and perceived degree of system quality, and to investigate the relationship between the perception-based measure of intention to use and the fact-based measure of actual usage. Furthermore, we also aim to add empirical findings on the general research question: what factors influence actual IS usage and how? In order to address the research question and to examine the research model, we selected a mobile campus application (MCA). We collected both fact data and survey data. For fact data, we retrieved them from the system logs such information as menu usage counts, user's device performance, display size, and operating system revision version number. At the same time, we conducted a survey among university students who use an MCA, and collected 180 valid responses. A partial least square (PLS) method was employed to validate our research model. Among nine hypotheses developed, we found five were supported while four were not. In detail, the relationships between (1) perceived system quality and perceived usefulness, (2) perceived system quality and perceived intention to use, (3) perceived usefulness and perceived intention to use, (4) quality of device platform and actual IS usage, and (5) perceived intention to use and actual IS usage were found to be significant. In comparison, the relationships between (1) quality of device platform and perceived system quality, (2) quality of device platform and perceived usefulness, (3) quality of device platform and perceived intention to use, and (4) perceived system quality and actual IS usage were not significant. The results of the study reveal notable differences from those of previous studies. First, although perceived intention to use shows a positive effect on actual IS usage, its explanatory power is very weak ($R^2$=0.064). Second, fact-based system quality (quality of user's device platform) shows a direct impact on actual IS usage without the mediating role of intention to use. Lastly, the relationships between perceived system quality (perception-based system quality) and other constructs show completely different results from those between quality of device platform (fact-based system quality) and other constructs. In the post-hoc analysis, IS users' past behavior was additionally included in the research model to further investigate the cause of such a low explanatory power of actual IS usage. The results show that past IS usage has a strong positive effect on current IS usage while intention to use does not have, implying that IS usage has already become a habitual behavior. This study provides the following several implications. First, we verify that fact-based data (i.e., system logs of real usage records) are more likely to reflect IS users' actual usage than perception-based data. In addition, by identifying the direct impact of quality of device platform on actual IS usage (without any mediating roles of attitude or intention), this study triggers further research on other potential factors that may directly influence actual IS usage. Furthermore, the results of the study provide practical strategic implications that organizations equipped with high-quality systems may directly expect high level of system usage.

기업 혹은 조직 거버넌스의 하위개념인 비즈니스 거버넌스와 IT 거버넌스는 학계에서 주요 연구과제가 되어 왔다. 그러나 비즈니스와 IT 도메인의 매개적 구조체로서 프로세스의 중요성에도 불구하고, 프로세스 거버넌스(PG)의 연구는 상대적으로 미흡하였다. PG는 비즈니스 전략을 IT시스템 구현과 연계하는 활동에 집중하며, 기업의 본원적 가치 창조 활동을 설명한다. 본 논문은 정치학, 사회학, 행정학에서의 기본적인 거버넌스 개념을 연구하고, 거버넌스 유형을 6개의 카테고리로 분류했다. 그리고 PG에 대한 일련의 메타모델을 제안한다. 예를 들면 전통적인 핸더슨과 벤카트라만의 SAM모델을 수정한 neo-SAM 모델, 조직 거버넌스 네트워크 모델, 조직거버넌스 순차모델, 조직 거버넌스 메타모델, 프로세스 거버넌스 큐브 모델, COSO와 프로세스 거버넌스의 비교 모델, 마지막으로 프로세스 거버넌스 프레임워크 등이다. SAM모델과 neo-SAM 모델의 주요한 차이점은 비즈니스 거버넌스와 IT 거버넌스 사이에 프로세스 거버넌스 도메인을 포함한 것이다. 여러 개의 메타 모델 중에서, 프로세스 거버넌스 프레임워크가 핵심 개념 모델로서 이는 4개의 활동차원 - 전략연계, 권한강화, 직능향상, 자율조직 - 으로 구성된다. 연구자는 각 활동차원 별로 5개씩 총 20개의 변인을 설계했다. 4개의 활동차원 외에도 프로세스 거버넌스 사이클을 움직이는 6개의 순환 동력 - 탈규범력, 미시권력, 활력, 자기조직력, 규범력, 센스메이킹 - 이 있다. 4개의 활동차원과 6개의 동력으로 조직은 내외부의 환경 변화에 대한 프로세스 거버넌스의 융통성을 유지할 수 있다. 본 연구는 프로세스 거버넌스 역량 모델과 프로세스 거버넌스 변인을 제안하는 목적을 가진다. 업계환경은 기능 중심 조직관리에서 프로세스 중심 관점으로 변화하고 있다. 연구자가 제안하는 프로세스 거버넌스 프레임워크가 향후 프로세스 거버넌스 도메인의 연구 확산을 위한 맥락적 참조모델과 아울러 프로세스 거버넌스 측정도구의 개발을 위한 조작적 정의의 틀을 제공할 것이다.
