일반적으로 암반 구조물의 안정성에 심각한 영향을 미칠 수 있는 것으로 알려진, 암반 내의 rock bridges는 일종의 opening-mode fracture로 간주될 수 있다. 초창기에는 재료의 저항 특성을 고려하여 rock bridges 자체의 거동 특성에 대한 연구가 있었으나, 최근에 와서는 수치 해석적 연구를 통해 파괴역학의 개념을 적용하여 rock bridges의 분포특성이 암반 구조물의 안정성에 미치는 영향 등을 새롭게 연구하고 있다. 본 연구에서는 rock bridges가 수압파쇄 균열의 분포특성에 미치는 영향을 규명하고자, rock bridges의 분포형태에 따른 암반 내 응력 분포 특성과 균열의 bridge 현상을 먼저 살펴보았다. 즉 , 균열의 길이에 대한 균열의 간격의 비 (s/L 비) 균열의 길이에 대한 균열의 오버랩의 비 (d/L 비)를 변화시키면서 응력 분포 특성을 수치 해석적으로 살펴본 결과, 2개의 균열만으로도 여러 개의 균열 분포 특성을 대표할 수 있음을 알았고, s/L 비가 감소할수록 또는 d/L비가 증가할수록 암반 내 응력 집중은 커짐을 알 수 있었다. 이러한 수치 해석결과를 토대로, 수압파쇄 균열과 rock bridges의 상호 관계를 수치 해석적으로 연구한 결과, rock bridges가 없을 경우 탄성이론에 맞게 발전하던 수압파쇄 균열이, rock bridges의 존재에 의해 수압파쇄 균열의 전파 방향이 왜곡됨은 물론 수압파쇄 균열에 수직으로 작용하는 원거리 응력도 정확히 표현하지 못함을 알았다. 즉 , 수압파쇄 균열 선단에서의 mode I 응력집중계수는 s/L비가 감소할수록 또는 d/L 비가 증가할수록 커짐을 알 수 있었다. 이러한 연구결과로부터, 균열의 분포특성을 규명하기 위해 노두에서 일반적으로 실시되는 scanline 조사에서 얻을 수 있는 s/L 비와 d/L 비를 통하여 암반 내에 존재하는 응력의 평가 방법이 새로이 제안할 수 있을 것이다.로 제안하였다. 본 노천채탄장의 최종사면과 같이 장기적인 유지를 필요로 하는 사면은 사면의 변형거동을 감시하기 위해 보다 체계적인 계측을 필요로 하며, 또한 사면이 많은 비에 노출되기 쉽기 때문에 사면의 풍화와 침식에 대한 대책연구도 수행되어야 한다. 이 값이 감소할수록 Cox-Merz 법칙은 더욱 잘 성립한다.$_{TM4}$/$\bar{p}$$_{TM2}$, $\bar{p}$$_{TM4}$/$\bar{p}$$_{TM1}$, log($\bar{p}$$_{TM4}$/$\bar{p}$$_{TM3}$) 등과 상관이 높게 나타났다.이 소요되었고, 우리 나라 자연환경에서는 5일에서 7월에 주로 이 충체의 유충이 발육되고 전파되는 것으로 추측되었다.러 가지 방법들을 적극 적용하여 금후 검토해볼 필요가 있을 것이다.잡은 전혀 삭과가 형성되지 않았다. 이 결과는 종간 교잡종을 자방친으로 하고 그 자방친의 화분친을 사용할 때만 교잡이 이루어지고 있음을 나타내고 있다. 따라서 여교잡을 통한 종간잡종 품종육성 활용방안을 금후 적극 확대 검토해야 할 것이다하였다.함을 보이고 있다.X> , ZnCl$_{3}$$^{-}$같은 이온과 MgCl$^{+}$, MgCl$_{2}$같은 이온종을 형성하기 때문인것 같다. 한편 어떠한 용리액에서던지 NH$_{4}$$^{+}$의 경우 Dv값이 제일 작았다. 바. 본 연구의 목적중의 하나인 인체유해 중금속이온인 Hg(II), Cd(II)등이 NaCl같은 염화물이 함유된 시료용액에 공해이온으로 존재할 경우 흡착에 의한 제거가 가능하다. 한편 이같은 중금속이온의 흡착실험은 특히

The primary purpose of this study was to identify factors affecting health promoting lifestyles of college students on the basis of Pender's Health Promotion Model. The subjects were 1,159 students of one university in Seoul. These data were collected by self reporting questionnaire from April 19 to May 3, 1993. This study examined health promoting lifestyles, cognitive-percep-tual factors: perceived health status, perceived importance of health, health locus of control, and health conception, and modifying factors: sex, grade, major, residence type, and attendance at a health care course. The instruments used in this study were Health Promoting Lifestyle Profile by Walker et al. (1987), Health Value Scale by Wallston et al. (1976), Health Locus of Control by Wallston et al. (1978), and Health Conception Scale by Laffrey(1986). The data were analyzed by Cronbach's $\alpha$, mean, standard deviation, percentage, t-test, ANOVA, Pearson's Correlation Coefficient, and Stepwise Multiple Regression with SPSS PC+ Program. The results were as follows : 1. The means of health promoting lifestyles revealed total 3.33, self actualization 3.74, health responsibility 2.72, exercise 2.80, nutrition 3.55, interpersonal surpport 3.76, and stress management 2.96. Interpersonal support showed the highest score and health responsibility showed the lowest score. 2. No significant differences between sex, grade, major, and residence type, and health promoting lifestyles Were founded(p>.05). Attendants at a health care course showed a significant higher score than nonattendants (p<.001). Male showed a significant higher score in exercise subscale, female showed significant higher scores in health responsibility, nutrition, interpersonal support, stress management subscales(p<.001), residence type showed a significant difference in nutrition subscale(p<.001). 3. No significant differences between perceived health status and sex, grade, major, residence type, and attendance at a health care course were founded(p>.05). Perceived importance of health showed no differences among sex, grade, major, and residence type(p>.05), showed only in attendance at a health care course (p<.001). Attendants at a health care course showed a significant higher score than nonattendants(p<.001). No significant differences between health conception and sex, grade, major, and residence type were founded (p>.05), only significant difference between health conception and attendance at a health care course was founded(p<.05). Nonattendants showed a significant higher score in clinical health conception, attendants showed a significant higher score in wellbeing health conception(p<.05). 4. A significant positive correlation between health promoting lifestyles and perceived health status was founded(r=.2415, p<.001). A significant positive correlation between health promoting lifestyles and perceived importance of health was founded (r=.1475, p<.001). The health promoting lifestyles revealed significant positive correlations in internal and powerful others locus of control (r=.3187, p<.001: r=.1475, p<.001), but revealed a significant negative correlation in chance locus of control(r=-.997, p<.001). A significant positive correlation between health promoting lifestyles and clinical health conception and wellbeing health conception were founded (r=.1241, p<.001 : r=.3047, p<.001). 5. Perceived health status was the highest factor predicting health promoting lifestyles of college students(R=.3415, $R^2=11.62$). Perceived health' status, perceived improtance of health, internal locus of control, wellbeing health conception, powerful others locus of control accounted for 28.19% in health promoting lifestyle patterns. In conclusion, college students who reported more helath promoting lifestyles evaluated their health positively, perceived importance of health highly, perceived their health as affected by theirselves, powerful others but not by chance or luck, and accepted health as high level wellness rather than merely the absence of illness. Those who attending at a health care course had healthier lifestyle patterns. And attendance at a health care course had significant. correlations in these cognitive-perceptual factors. Further studies are required to identify reasons of attending a health care course, and to compare health promoting lifestyles pre-post attending a course related to health care.

Background: Cardiac arrest is one of the most critical diseases which can likely lead to severe cerebral disability or brain death when the cases can not recover their circulation within 10 minutes. Saving out-of-hospital cardiac arrest cases is a recent concern in Korea. Resuscitation has become an important multidisciplinary branch of medicine, demanding a spectrum of skills and attracting a plethora of specialities and organizations. The best survival can be achieved if all the following links have been optimized : rapid access, and early CPR, defibrillation and ACLS, Since the "Utstein Style" was advocated in 1991, many reports about out-of-hospital cardiac arrest have been published based on this guideline. These differences prevent valid inter-hospital and international comparisons. However, it is not known how effective resuscitation has become to the patients. In other words, there are no guidelines for reviewing, reporting, and conducting research on resuscitation in Korea. This dissertation aims to provide the basic data for a unified reporting guideline of resuscitation in Korea and evaluating the out-of-hospital factors associated with survival discharge of out-of-hospital cardiac arrest. Methods: As for this study, uses the collected data about Out-of-hospital cardiac arrests at 4 area, from January, 2005 to April. 2005. With a retrospective study, 174 cases were analyzed. The data was recorded based on the Out-of-Hospital Utstein Style. Results: Resuscitation was performed on 174 out-of-hospital cardiac arrest cases at the 4 area 14 patients(8.1%) recovered their spontaneous circulation. Overall, the ROSC of the out-of-hospital cardiac arrest patients was 8.1%, which was poorer than that of western countries. Gender distribution was 50 females(28.7%) and 124 males(71.3%), approximately twice as many males as females. ROSC of witnessed arrests was found out to be 97.7%. The ratio of the witnessed arrest groups showed higher results than that of unwitnessed arrest groups in the above-examined cases. Cardiac etiology consisted of cardiac(33.5%), non-cardiac(45.7%), trauma(20.1%), and unknown(6.0%). Cardiac was the best performance. Initial rhythm showed Ventricular Tachycardia/pulseless Ventricular Fibrillation in 8 patients(6.0%), asystole in 100(75.2%) and unknown in 25(18.8%). The results of the Ventricular Tachycardia/pulseless Ventricular Fibrillation showed higher results than the others cases, The proportion of the cardiogenic cause was 33.5%, which was only half of western countries. Ventricular Tachycardia/pulseless Ventricular Fibrillation is relatively rare. These differences were due to the prevalent pattern of Out-of-hospital cardiac arrest as well as prematurity of the EMSS. Bystander CPR was practiced on 13 patients(7.52%). ROSC was shown in 46.2% cases. CPR by EMT was carried out on 167 cases(96.5%). ACLS by EMf was rare. From collapse, 4 cases(2.6%) arrived to ED within 6 minutes. 13 (8.6%) within 10 minutes, and 49(32.5%) over 31 minutes. The sooner the patients arrived, the greater the ratio of ROSC and discharged alive became, and the same with collapse time to ROSC. As the results of the logistic regression analysis, ROSC was found out to be highly influenced by the time of ED arrival from collapse and Ventricular Tachycardia/pulseless Ventricular Fibrillation. Therefore, the ratio of ROSC depends on not any single factor but various intervention factors. Conclusion: This dissertation presents the following suggestions and directions of the study hereafter. First, the first step for a chain of survival should be taken to activate EMSS early with a phone as soon as cardiac arrests are witnessed. Second, it is keenly needed that emergency medical technicians should be increased through emergency education for living. Third, it is necessary to establish the emergency transportation system. Fourth, most of the Koreans have little understanding of EMT and the present operation systems have many problems, which should be fundamentally changed. Fifth, it is required to have an active medical control over Out-of-hospital CPR, And proper psychological supports should be given not only to patients themselves and their family but also individuals who are engaged in emergency situation. Finally, through studies hereafter on nationwide, comprehensive, and standard forms, it is needed to examine into the biological figures of human body, causes and trends of cardiac arrests, and then, to enhance the survival rate of Out-of-hospital cardiac arrests. Korean guidelines for Cardiopulmonary resuscitation need to be made.

이 연구는 전라북도를 사례로 부모-자녀 세대에 걸쳐 진행되는 단계적 이동이 비수도권 중소도시 인구 성장에 미치는 영향을 탐색하는 것이다. 이를 위해 부모 세대를 베이비 부머, 자녀 세대는 에코 부머로 설정하였고, 거시자료를 이용하여 이들의 출생, 분포 변화와 선별적 이동과정을 추적하였다. 그리고 단계적 이동을 분석하기 위해 전라북도 시부, 군부 및 타 시도를 각각 출발지와 도착지로 설정하였다. 연구의 주요 결과는 다음과 같다. 첫째, 베이비 부머 세대는 전라북도 시부보다 군부에서 출생아수가 약 7배 이상 많았던 것으로 추정된다. 둘째, 부모 세대가 성장하여 선별적 이동을 진행할 때, 전라북도 시부와 군부 모두에서 타 시도로, 특히 수도권과 대도시로 이출이 탁월하게 나타났다. 하지만 전라북도 군부 출생자 상당수는 시부로도 이동하였고, 그 이동량은 전라북도 시부에서 타 시도로 이출한 양을 채워주는 수준이었다. 셋째, 자녀 세대에서는 전라북도 군부보다 시부에서의 출생아수가 더 많은데, 이것은 부모 세대가 농촌에서 도시로 단계적 이동을 했던 것에 기인한다. 넷째, 자녀 세대의 20대 연령 선별적 이동에서도 부모 세대와 유사하게 수도권과 대도시 등으로 이출이 압도적인 비율을 차지하였다. 그러나 전라북도 군부에서 시부로 이입되는 이동량이 부모 세대에 비해 현저하게 줄어들었고, 결과적으로 전라북도 도시들에서 음(-)의 순이동자 수가 해마다 누적되고 있다. 마지막으로 단계적 이동은 인구의 사회적 성장요인이자 동시에 이동자 생애경로의 결혼, 출산, 양육 등과 결부되어 자연적 성장요인에도 영향을 주었다. 따라서 부모-자녀 세대에 걸쳐 진행되는 단계적 이동은 비수도권 중소도시 인구의 증가와 감소를 결정짓는 주요한 요인이라고 할 수 있을 것이다.

무인항공기는 조종사를 탑승하지 않고 지정된 임무를 수행할 수 있도록 제작한 비행체로서 독립된 체계 또는 우주 지상체계들과 연동시켜 운영 하는 기체이다. 이 같은 무인항공기의 경제발전의 가능성으로 인하여 정부는 무인항공기가 세계 항공기 시장에서 우리나라가 항공 선진국으로 진입할 수 있도록 적극 지원 중이다. 무인항공기는 항공산업 발전의 블루오션이지만 이에 따르는 법적 분쟁 요소도 만만치 않다. 소형으로 제작된 무인항공기는 고성능 카메라 및 센서에 기록되는 이착륙 및 운항노선 주변의 기록들을 피찰영자의 동의 없이 마음 것 촬영할 수 있는바 이에 대한 사생활 침해에 대한 우려가 있다. 또한 무인항공기가 민간상용화 된다면 무분별한 사용으로 사생활 침해 발생이 예상된다. 무인항공기로 인해 국민이 원치 않는 사생활 노출이 발생한다면 무인항공기 운영자들에게 손해배상책임이 발생할 수 있고, 이는 무인항공기산업 발전을 위해 고려되어야 하는 요소이다. 현재 무인항공기 산업을 주도하고 있는 미국에서도 무인항공기 사생활 침해 관련 정책은 개발 중이며, 효율적인 대책 마련을 준비하고 있다. 무인항공기에 관련한 법이 시행되고 있지 않기 때문에 무인항공기 사생활 침해에 따른 모든 법적 대책을 마련하는 것이 필요하다. 미국과 같이 무인항공기 사생활 보호를 도모하기 위해 무인항공기 사생활보호법(안)을 제시하였다. 현재 시행 중인 법이 많기 때문에 새로운 법안을 제시하는 것은 법적 안정성을 해할 수 있지만 국민들의 안전한 삶을 위해서 법을 제정하는 것은 피할 수 없는 일이다. 개인정보보호법이 시행 중이지만 무인항공기 관련 사생활 침해가 발생했을 때 무인항공기의 특수성에 대한 개인정보보호법을 적용하기기 녹록치 않을 것이기 때문에 미국 입법안과 개인정보보호법을 참고하여 무인항공기의 사생활 침해를 대비한 사생활보호법(안)을 제시하였다.

Health education, as the most fundamental concept for national health promotion, alms for developing the self-care ability of the general public. High school days are regarded as the period when most important physical, mental and social developments occur, and most health-related behaviors are formed. School health education is one of the major learning resources influencing health potential in the home and community as well as for the individual student. High school health education in Korea has a fundamental systemic flaw in that health-related subjects are divided and taught under various subjects areas at school. In order to achieve the goal of school health education, it is essential to make a systematic assessment of the learner's concerns connected with his health and life, and the factors affecting them. So far, most of the research projects that had been carried out for improving high school health education were limited in their concerns to a particular aspect of health. Even though some had been done in view of comprehensive school health education, they failed to Include a health assessment of the learner. Therefore, in this study the high school students' concerns related to health and life were investigated in the first place on the basis of the PRECEDE model, developed by Green and others for the purpose of a comprehensive diagnostic research on high school health education. This study was done in two steps : one was the basic study for developing research instrument and the other was the main one. The former was conducted at five high schools in Seoul and Cheongju for 2 months-beginning in March, 1996. The students were asked to respond to questions related to their health and lives in unstructured open-ended question forms. On the basis of analysis of the basic study, the diagnostic instruments for the quality of life, health problems, health behavior and educational factors were constructed to be used for the collection of data for main study. An expert panel and the pilot study were used to improve content validity and reliability of the instruments. The reliability of the instruments was measured at between .7697 and .9611 by the Cronbach $\alpha$. The data for this study were collected from the sample consisted of the junior and senior classes of twenty general and vocational high schools in Seoul and Cheongju for two months period beginning in July, 1996. In analyzing the data, both t-test and $X^2$-test were done by using SAS-$PC^+$ Program to compare data between the sexes of the high school students and the types of high school. A canonical correlation analysis was carried out to determine the relationships among the diagnostic variables, and a multivariate multiple regression analysis was conducted by using LISREL 8.03 to ascertain the influences of variables on the high school students' health and quality of life. The results were as follows : 1) The findings of the hypothesis tests (1) The canonical correlation between the educational diagnosis variables and behavioral, epidemiological, social diagnosis variables was .7221, which was significant at the level of p<.001. (2) The canonical correlation between the educational diagnosis variables and the behavior variables was .6851, which also was significant (p<.001). (3) The canonical correlation between the behavioral diagnosis variables and the epidemiological variables was 4295, which was significant (p<.001). (4) The canonical correlation between the epidemiological diagnosis variables and the social variables was .6005, which was also significant (p<.001). Therefore, the relationship between each diagnosis variable suggested by the PRECEDE model had been experimentally proven to be valid, supporting the conceptual framework of the study as appropriate for assessing the multi-dimensional factors affecting high school students' health and quality of life. Health behavior self-efficacy, the level of parents' interest and knowledge of health, and the level of the perception of school health education, all of which are the educational diagnostic variables, are the most influential variables in students' health and quality of life. In particular, health behavior self-efficacy, a causative factor, was one of the main influential variables in their health and quality of life. Other diagnostic variables suggested in the steps of the PRECEDE model were found to have reciprocal relations rather than a unidirectional causative relationship. The significance of this research is that it has diagnosed the needs of high school health education by the learner-centered assessment of variety of factors related to the health and the life of the students. This research findings suggest an integrated system of school health education to be contrived to enhance the effectiveness of the education by strengthening the influential factors such as self-efficacy to improve the health and quality of the lives of high school students.

본 연구는 전라남도지역 대학급식의 서비스 품질에 대한 인식 및 고객의 태도를 파악하고 대학급식의 운영전략을 제안하고자 수행하였다. 2011년 8월 30일에서 11월 30일 사이에 설문조사를 진행하였고, 총 600부의 설문지를 배포하여 총 580부가 회수되었으며, 부적절한 응답을 한 것을 제외하고 571부를 최종분석에 사용하였다. 대학급식 이용 실태조사 결과, 대학급식을 전혀 이용하지 않고 있는 비율이 21.9%로 조사되었고, 48.7%가 1주일에 1~2회 정도만 대학내에 급식을 이용하고 있는 것으로 나타났고, 1주일에 3~4회 이용은 20.4%로 나타나 대학급식의 이용횟수가 비교적 좋지 않은 것으로 나타났다. 서비스 품질에 대한 평균 수행도는 3.01점으로 중간 수준을 보였다. '편이성' 점수가 3.25점으로 '서비스 품질' 점수(2.93)와 '음식 품질' 점수(2.94)보다 높은 수행도 인식을 가지고 있는 것으로 조사되었다. 13개의 항목 중에서 '식당위치의 편리성(3.31)'이 가장 높은 수행점수로 나타났고, 그 다음으로 '신속한 배식(3.23)', '식사 가격(3.22)'으로 조사되었다. 반대로 '메뉴선택의 다양성(2.60)'은 가장 낮은 수행도로 조사되었다. 대학급식에서 우선적으로 개선해야할 품질속성을 제언하기 위하여 서비스품질 속성에 대한 인식도와 중요도를 기초로 IPA 수행한 결과, 대학급식에서 우선적으로 개선이 필요한 속성으로는 '음식의 맛', '메뉴선택의 다양성', '음식의 질(재료의 신선도)'로 분석되었다. 중요도 수행도 모두 높은 항목은 '위생 및 청결', '식사가격'으로 분석되었다. 이에 비해 중요도 수행도 모두 낮은 항목으로는 '편안하고 조용한 식사분위기', '쾌적한 환경', '고객 불만에 대한 신속한 처리'로 분석되었고, 중요도 대비 수행도가 높은 항목으로는 '식당위치의 편리성', '신속한 배식서비스', '음식의 양', '종업원의 서비스', '영양적으로 균형 있는 식사'로 조사되었다. 서비스 품질이 전반적인 만족도에 미치는 영향 분석결과, 대학급식의 전반적인 만족도에 영향을 미치는 회귀계수에는 '음식(p<0.001)'과 '편이성(p<0.05)'으로 분석되었고, 서비스 품질이 가치에 미치는 영향을 분석한 결과, 대학급식의 가치에 대한 인식에 영향을 미치는 독립변수는 '음식(p<0.001)'과 '서비스(p<0.05)'로 분석되어 가치에는 '음식'이 가장 큰 영향을 미치고 '서비스'가 그 다음 순으로 분석되었다. 서비스 품질이 재방문의도에 미치는 영향분석결과에서는 재방문의도에는 '음식'이 가장 큰 영향을 미치고 '서비스'가 그 다음 순으로 나타났다. 서비스 품질이 추천의도에 미치는 영향 분석결과에서는 '음식(p<0.001)'만 유의적인 정(+)의 영향을 미치는 것으로 분석되었다. 이상의 결과를 종합하여 볼 때 대학급식의 고객인 대학생들이 인식하는 대학급식은 대학 내에 편리한 장소에 위치하여 신속하게 양껏 먹을 수 있는 편이성과 종업원들에 대한 서비스는 상당히 만족하는 것으로 분석된 반면에 음식의 맛과 다양성, 그리고 음식의 질에 대해서는 상당히 불만족한 요인으로 분석되었다. 이에 대해 음식의 맛과 메뉴 선택의 다양성 개선을 위한 실질적인 운영전략을 세우고 노력해 나가야 할 것이다.

The purpose of this study was to examine factors influencing the meaning of life for middle-aged women. The subjects for the study were 190 middle-aged women who live in Busan. Data were collected from May 25 to June 20, 1999. The instruments for this study were as follows : the meaning of life scale developed by Jung D. R(1978) ; the self-esteem scale developed by Ro, E. Y, Kwon, J. H.(1997) ; the volunteer activity scale developed by Park G. J.(1999), the marital satisfaction scale developed by Choi G. Y.(1999) ; and the health status scale developed by Kim S. Y. (1991). SPSS PC+ was utilized for data analysis. Data were analysed according to frequency and percentage, mean and standard deviation, t-test, ANOVA, Sheffe' s test and Pearson' s correlation coefficients and stepwise multiple regression. The reliability of the tools was tested by Cronbach's $\alpha$ : and it showed reliability scores of 0.88(for the meaning of life tool), 0.81(for the self-esteem tool), 0.94(for the marital satisfaction tool) and 0.78(for the health status tool). The results were as follows: 1) The scores showed that middle-aged women had a moderate level of meaning of life, with a mean of 30.31 and standard deviation of 6.24 (with values ranging from 12.00 to 48.00). The scores showed that middle-aged women had a moderate levels of self-esteem, with a mean of 28.92 and standard deviation of 4.67 (with values ranging from 10.00 to 40.00). The scores showed that middle-aged women had a very low level of volunteer activity, with a mean of 0.87 and standard deviation of 0.93(with values ranging from 0.00 to 1.00). The scores showed that middle-aged women had a moderate level of satisfaction in their marriages, with a mean of 31.99 and standard deviation of 7.84(with values ranging from 12.00 to 48.00). The scores showed that middle-aged women had a moderate level of health status, with a mean of 6.63 and standard deviation of 1.57(with values ranging from 3.00 to 9.00). 2) There was a statistically significant difference of the meaning of life of middle-aged women according to their religion(F=8.930, p=.000), christian ($31.94{\pm}5.96$) had more meaning th life than buddhists ($28.40{\pm}6.23$). 3) There was a statistically significant correlations between the subject' s self-esteem and the her meaning of life(r=0.477, p=0.000), the subject' s level of volunteer activity and meaning of life(r=.428, p=.000), her level of marital satisfaction and meaning of life(r=.417, p=.000), and her level of health status and meaning of life(r=.261, p=.000) among these middle-aged women. 4) Self- esteem was the highest factor influencing the level of meaning of life in middle-aged women. 40.0% of the total variance of levels of meaning of life by was dependent on self-esteem, volunteer activity, marital satisfaction and health status. In conclusion, the higher the self-esteem and levels of volunteer activity, marital satisfaction, and health status of middle-aged women, the higher the meaning of life for them. Therefore, it is necessary to elevate levels of the self-esteem and volunteer activity, marital satisfaction and health status in order to help middle-aged women have more meaning of life.

Smartphone and its applications (i.e. apps) are increasingly penetrating consumer markets. According to a recent report from Korea Communications Commission, nearly 50% of mobile subscribers in South Korea are smartphone users that accounts for over 25 million people. In particular, the importance of smartphone has risen as a geospatially-aware device that provides various location-based services (LBS) equipped with GPS capability. The popular LBS include map and navigation, traffic and transportation updates, shopping and coupon services, and location-sensitive social network services. Overall, the emerging location-based smartphone apps (LBA) offer significant value by providing greater connectivity, personalization, and information and entertainment in a location-specific context. Conversely, the rapid growth of LBA and their benefits have been accompanied by concerns over the collection and dissemination of individual users' personal information through ongoing tracking of their location, identity, preferences, and social behaviors. The majority of LBA users tend to agree and consent to the LBA provider's terms and privacy policy on use of location data to get the immediate services. This tendency further increases the potential risks of unprotected exposure of personal information and serious invasion and breaches of individual privacy. To address the complex issues surrounding LBA particularly from the user's behavioral perspective, this study applied the privacy calculus model (PCM) to explore the factors that influence the adoption of LBA. According to PCM, consumers are engaged in a dynamic adjustment process in which privacy risks are weighted against benefits of information disclosure. Consistent with the principal notion of PCM, we investigated how individual users make a risk-benefit assessment under which personalized service and locatability act as benefit-side factors and information privacy risks act as a risk-side factor accompanying LBA adoption. In addition, we consider the moderating role of trust on the service providers in the prohibiting effects of privacy risks on user intention to adopt LBA. Further we include perceived ease of use and usefulness as additional constructs to examine whether the technology acceptance model (TAM) can be applied in the context of LBA adoption. The research model with ten (10) hypotheses was tested using data gathered from 98 respondents through a quasi-experimental survey method. During the survey, each participant was asked to navigate the website where the experimental simulation of a LBA allows the participant to purchase time-and-location sensitive discounted tickets for nearby stores. Structural equations modeling using partial least square validated the instrument and the proposed model. The results showed that six (6) out of ten (10) hypotheses were supported. On the subject of the core PCM, H2 (locatability ${\rightarrow}$ intention to use LBA) and H3 (privacy risks ${\rightarrow}$ intention to use LBA) were supported, while H1 (personalization ${\rightarrow}$ intention to use LBA) was not supported. Further, we could not any interaction effects (personalization X privacy risks, H4 & locatability X privacy risks, H5) on the intention to use LBA. In terms of privacy risks and trust, as mentioned above we found the significant negative influence from privacy risks on intention to use (H3), but positive influence from trust, which supported H6 (trust ${\rightarrow}$ intention to use LBA). The moderating effect of trust on the negative relationship between privacy risks and intention to use LBA was tested and confirmed by supporting H7 (privacy risks X trust ${\rightarrow}$ intention to use LBA). The two hypotheses regarding to the TAM, including H8 (perceived ease of use ${\rightarrow}$ perceived usefulness) and H9 (perceived ease of use ${\rightarrow}$ intention to use LBA) were supported; however, H10 (perceived effectiveness ${\rightarrow}$ intention to use LBA) was not supported. Results of this study offer the following key findings and implications. First the application of PCM was found to be a good analysis framework in the context of LBA adoption. Many of the hypotheses in the model were confirmed and the high value of $R^2$ (i.,e., 51%) indicated a good fit of the model. In particular, locatability and privacy risks are found to be the appropriate PCM-based antecedent variables. Second, the existence of moderating effect of trust on service provider suggests that the same marginal change in the level of privacy risks may differentially influence the intention to use LBA. That is, while the privacy risks increasingly become important social issues and will negatively influence the intention to use LBA, it is critical for LBA providers to build consumer trust and confidence to successfully mitigate this negative impact. Lastly, we could not find sufficient evidence that the intention to use LBA is influenced by perceived usefulness, which has been very well supported in most previous TAM research. This may suggest that more future research should examine the validity of applying TAM and further extend or modify it in the context of LBA or other similar smartphone apps.
