The aging process is multifactorial and results from the combined effects of inherited(genetic) and acquired factors including life style, food habits, physical activity, and diseases. That give rise to the various approaches in aging. We are trying to study biological changes with aging, In detail we are focused on gene and protein function accompanied by normal or abnormal aging process, especially our efforts are aimed at revealing the functional relationship of proteins in aging as a final product of gene. We expect that proteomic approach to the study of protein function involved in aging should give us variety of integrated data to understand biological changes of long lived lives, We have applied expression proteomics to rat liver bred in dietary restriction or in at libitum to elucidate the effects of food habit on aging. Expression proteomics shows us protein profile in a selected tissue or cells as a whole and gives us the information about protein expression level, posttranslational modification and degenerative modification of expressed proteins. Comparative analysis of young and old rat liver by two dimensional gels shows that gene expression of several proteins was down regulated in old rats and some protein expression level is increased with aging. Dietary restriction slows down these changes of gene expression and in some proteins there's no difference in protein expression level at same ages in comparison with rats bred in at libitum. About forty protein was identified by peptide mass fingerprint with MALDI-TOF and rest of the protein of interest is in the course of identification, Also we are trying to make mitochondrial and cytosolic proteom reference map. These suborganelle proteom map will gives us the information about low abundance proteins and cellular localization of proteins. Proteomics is a growing methodology to study biological system. High throughput qualitative and qualitative aspect of this approach will gives us large amount of integrated information and speed up our understanding about biological system

Objective: Microscrew implants (MSls) offer many advantages, but some complications are known to occur during their insertion. One of the most commonly reported complications is root injury. Our aim was to identify factors associated with root injury and to evaluate their qualitative and quantitative values. Methods: Thirty-five orthodontists placed MSls (AbsoAnchor$AbsoAnchor^{(R)}$, Dentos Co. Ltd, Daegu, Korea) in the upper jaw of typodonts, labially between the second premolar and the first molar, in low and high vertical positions. Root contacts were counted, and distances between MSI apices and roots were measured. Fear level of the orthodontists was surveyed before and after the experiment. Wilcoxon's test, chi-square test, and Mann-Whitney test were used for statistical analysis. Results: Overall root contact rate of MSI insertion was 23.57%. The root contact rate was significantly higher in MSls inserted at $90^{\circ}$ (45.71%) than at $30^{\circ}$ (1.43%). The distance between the dental root and MSI also increased significantly in MSls inserted at $30^{\circ}$. Mean fear level before MSI insertion (4.6) significantly decreased after insertion (3.2); the causative factors were risk of injury to dental root and maxillary sinus or mandibular canal. Conclusions: Root injury is relatively rare, and oblique angulation reduces the risk of root and MSI contact.

The purpose of this research was conducted to formative processes and to interpret premarital adult's sexuality meaning. The interviews have been executed based upon ethnography approach and method of interview in depth within the framework of the Weis's sexual script theory (1998) and parent-children relation. The interview in depth has been conducted with unmarried 7 males and 8 females inclusive of college students, total 15 persons who were born 1974-1980 and living in Seoul and nearby suburban areas. A period of interviews were carried out from September until December 2003. Each interview was executed for 2 to 4 hours apiece, and each person had 2 to 4 interviews during the period. The result of analysis of the sexuality scripts theory from three different views indicates that the female informants appeared to rationalize the fact that traditional concept of the chastity as defined by the socio-cultural level has been changed. It also indicated that there were very few sex educations in the society at large except for the public medias including the Internet. The interrelation level indicates that positive interaction with the opposite sex has affected them in the course of their building up desirable personal relationship in the society and uplifting their sense of self-esteem. The internal level of sexuality, it is much dependent on the extent of individual inner recognition of sexuality. The parent-children relation view of sexuality, the most influential factor for their communication on sexuality lies in the extent of their realization on how positively their parents recognize their children.

Family dissolution and economic difficulties of the grandchild's parents are the most prevailing reason for an increase of grandparent-headed families in rural Korea. However, there is a lack of empirical research looking at the experiences of custodial grandmothers, social support, and their psychological well-being. In this regard, this study examined the effect of social support (formal & informal) on the psychological well-being of custodial grandmothers in rural Korea. For this purpose, quantitative and qualitative research methods were conducted. Quantitative data were gathered, using structured questionnaire, from 311 grandmothers who were raising their grandchildren in rural Korea as primary care-givers. Statistical methods used for data analysis were descriptive statistics and hierarchical regression analysis with SPSS WIN 19.0 programs. Qualitative data were collected by in-depth interviews to 10 custodial grandmothers in rural area. The results of this study are as follows. First, almost half of the parents of the grandchild didn't visit and didn't call anymore. Some relatives -aunt, uncle, etc.- support the grandparent-headed family economically and emotionally. 3/4 of the grandparent-headed families were supported by the government and community. This was not small numbers, but the amount of economic support was low. Second, grandmothers in the study showed quite a high level of depression while their happiness level was relatively low. There were differences in the factors influencing the level of happiness/depression of these rural grandmothers. Overall, the study's results showed the importance of formal & informal support for psychological well-being of the custodial grandmothers in rural Korea. Policy and theoretical implications are discussed.

In this study, the shutdown system of the fuel gas supply system is designed based on the Safety Integrity Level of IEC 61508 and IEC 61511. First of all, the individual risk($10^{-4}$/year) and the risk matrix which are the risk acceptance criteria are set up for the qualitative risk assessment such as the HAZOP study. The natural gas leakage at the gas supply pipe is identified as the highest risk among the hazards identified through the HAZOP study and as a safety instrumented function the shutdown function for leakage was defined. SIL 2 and PFD($2.5{\cdot}10^{-3}$) for the shutdown function are determined by the layer of protection analysis(LOPA). The shutdown system(SIS) carrying out the shutdown function(SIF) is verified and designed according to qualitative and quantitative requirements of IEC 61508 and IEC 61511. As a result of SIL verification and SIS conceptual design, the shutdown system is composed of two gas detectors voted 1oo2, one programmable logic solver, and two shutdown valve voted 1oo2.

Objectives: To prevent the spread of coronavirus disease 2019 (COVID-19), behaviors such as mask-wearing, social distancing, decreasing mobility, and avoiding crowds have been suggested, especially in high-risk countries such as Indonesia. Unfortunately, the level of compliance with those practices has been low. This study was conducted to determine the predisposing, enabling, and reinforcing factors of COVID-19 prevention behavior in Indonesia. Methods: This cross-sectional study used a mixed-methods approach. The participants were 264 adults from 21 provinces in Indonesia recruited through convenience sampling. Data were collected using a Google Form and in-depth interviews. Statistical analysis included univariate, bivariate, and multivariate logistic regression. Furthermore, qualitative data analysis was done through content analysis and qualitative data management using Atlas.ti software. Results: Overall, 44.32% of respondents were non-compliant with recommended COVID-19 prevention behaviors. In multivariate logistic regression analysis, low-to-medium education level, poor attitude, insufficient involvement of leaders, and insufficient regulation were also associated with decreased community compliance. Based on in-depth interviews with informants, the negligence of the Indonesian government in the initial stages of the COVID-19 pandemic may have contributed to the unpreparedness of the community to face the pandemic, as people were not aware of the importance of preventive practices. Conclusions: Education level is not the only factor influencing community compliance with recommended COVID-19 prevention behaviors. Changing attitudes through health promotion to increase public awareness and encouraging voluntary community participation through active risk communication are necessary. Regulations and role leaders are also required to improve COVID-19 prevention behavior.

본 연구에서는 지질자원 분야 연구개발 수월성을 제시할 수 있는 평가방법인 계량서지학(Bibliometrics)의 SCI논문 분석을 통해 질적평가 지표를 제시하고, 이를 KIGAM의 6개 세계수준 후보 연구실의 기술수준 분석에 적용했다. Heo et al. (2008), Cho (2013)에서 제시되었던 표준화된 순위보정 영향력 지수(mrnIF)를 연구수월성 지표로 활용하였다. 2012년 편당 IF는 희유자원활용 분야 KIGAM 연구실이 가장 높았으나 순위(position) 지수 및 표준화된 순위보정 영향력 지수(mrnIF)는 지하수(최고순위 적용 position/mrnIF), 자원탐사개발(평균순위 적용 position/mrnIF) 분야가 제일 높게 나타났다. 시계열 분석 결과 표준화된 순위보정 영향력 지수(mrnIF)는 지하수 분야 연구실이 2009년, 2011년 실적이 월등이 좋으나 타년도의 경우 도시광산 및 자원탐사개발 분야 연구실이 우수한 실적을 보이는 것을 알 수 있다. 수월성 지표로 전체 게재논문 중 표준화된 순위보정 영향력 지수(mrnIF)가 80 이상인 비율 및 90 이상인 비율로 비교한 결과, 2011년의 경우 지하수 분야 연구실이 가장 우수하였으나 다른 연도의 경우 지표별로 다른 순위를 보여 가장 우수하다고 보기 어려웠다. Cho (2013)의 최고등급 연구수월성 지표인 90 이상 논문 비율 20% 이상을 도시광산 분야 연구실이 만족하고 있으며 지하수 분야 연구실은 평균순위를 적용한 2010년을 제외하고 만족하고 있었다. 이와 같이 양적인 논문 수 뿐 만 아니라 논문의 질적 분석을 통해 해당 연구실의 기술수준을 비교할 수 있었다. 세계 수준의 연구실이 되기 위해서는 양적인 SCI 논문 수의 확대 뿐 만 아니라 논문의 질적 향상을 위해 노력해야 할 것이다.
