This study was conducted to identify the relationship between sleep quality, stress, depression, and eating attitudes of shift work nurses, and to determine the influencing factors of eating attitudes. Participants were 152 shift work nurses working at a university hospital and data collection was performed from July 1 to July 20, 2021. The collected data were analyzed by descriptive statistics, t-test, ANOVA, Pearson's correlation coefficient, and multiple regression. In this study, the prevalence of abnormal eating attitudes at clinical and sub-clinical levels was 7.9% and 19.1%, respectively. There was a positive correlation between eating attitudes and depression, and the influencing factors of eating attitudes were alcohol drinking(1 time/month) and depression. Therefore, it is necessary to find strategies to prevent depression in order to improve the eating attitude of nurses working in shifts, and repeated research on the relevance of alcohol drinking and eating attitudes is needed.

Purpose: To evaluate the impact of postoperative radiotherapy on loco-regional failure in patients with vulvar carcinoma and to determine the treatment strategy for inguinal lymph nodes. Materials and Methods: Sixty-six patients who received treatment for primary vulvar carcinoma at Seoul National University Hospital, from October 1979 through June 2004, were retrospectively analyzed. Sixteen patients were excluded from the analysis due to the following reasons: distant metastases in two patients; palliative intent for six patients; previous radiotherapy given to the pelvis in three patients; follow-up loss after surgery for four patient; insufficient medical records for one patient. Of 50 eligible patients, 35 were treated with surgery alone(S), ten were treated with surgery followed by radiotherapy(S+RT), and five were treated with radiotherapy alone. Results: The 5-year overall survival(OS) and disease-free survival(DFS) rates of all patients were 91% and 78%, respectively. Twelve patients(26%) experienced treatment failures and the sites of initial failure were as follows: a primary site in eight patients; regional lymph nodes in three patients; the lung in one patient. Although risk factors for failure were more common in the S+RT group than the S group of patients(p<0.05), the DFS rates were similar for the two groups(5-year DFS rates, 78% vs. 83%, p=0.66). The incidences of occult lymph node metastases was 10%. Ten of 31 patients with clinically negative lymph nodes did not received inguinal lymph node dissection, but no patient experienced regional failure. Conclusion: Postoperative radiotherapy may have a potential benefit for patients with risk factors for failure. The omission of inguinal dissection or elective radiotherapy to the inguinal lymph nodes may be considered in low-risk patients with clinically negative lymph nodes.

The focus of the research was on identifying the risk factors that may result in unprepared intercourse among the adolescent from an ecological systems prospective. A survey questionnaire was conducted from September through December 1999 to 2326 youths, ages from 13-18 years old. After eliminating thirty respondents from Unwed Mother's Home we found that 8.8% of the remaining respondents had experienced sexual intercourse. Of those, 5% of the female and 13.4% of male adolescents has had sexual intercourse, showing 2.7 times more for the male sample population. Broken down to age groups, 3.2% of the thirteen years old group and 19.2% of the eighteen years old group had experienced intercourse, an almost six fold increase in the older age group. To find out the differences between those who had and not had experienced intercourse the group was then divided into two comparative groups by same sex and age variables. Findings from comparative analysis identified five ecological system risk factors among the youth sample that had intercourse；First, individual factor：adolescents who thought less of themselves or didn't consider their potentials, those more exposed other risk behaviors such as drinking, smoking, drugs, runaway and come in contact with pornography, those who thought they knew more about sex and etc. Second, family factor：those who thought family was less important, had less supportive family, higher or lower income family and etc. Third, peer factor：Both groups thought friends were important and had their support. The group with intercourse experience seems to be think that more peers are experiencing other risk behavior. Fourth, school factor：Those in the group who had experienced intercourse seems to think school is less important and with lower academic achievements. Fifth, community factor：There were no statistical significant differences found between the two groups. The overall results from this study implies that if we want to prevent our youths from having unprepared intercourse during adolescence the significance of having meaningful emerging self, family relationship and school experience is important. This study identified the risk factors leading to adolescent sexual intercourse but further research is necessary in finding out about their predictability.

This study aims to examine developmental trajectories and predictor variables of problem behaviors and school adjustment trajectories among children from low-income families using latent growth modeling. The data was collected from the 2nd year to the 4th year (2012-2014) of a community child center child panel survey conducted by the National Youth Policy Institute. The major findings are as follows. First, as the grade went up, the problem behaviors of children from low-income families increased while school adjustment decreased. Second, multi-level domains, such as individual, school, and family variables influenced school adjustment trajectory, while only individual variables, such as depression, isolation, and motivation for achievement influenced problem behavior trajectory. Third, common protective factors between problem behaviors and school adjustment trajectories were motivation for achievement in and satisfaction of the community child center. Common risk factors between problem behaviors and school adjustment trajectories were isolation and aggression. Based on the results, the implications for child welfare practices were discussed.

Research on elderly suicide has increased since 2000. It indicates that elderly suicide is receiving a great attention as a part of elderly problems, and policy efforts are needed. However, most of existing research on elderly suicide focused on factors of elderly suicide. Therefore discussion about suicidal prevention measures is staying on general and suggestive level. As a result, this study is trying to seek effective prevention strategies of elderly suicide through systematic analysis of suicidal factors and sporadic policy proposals presented in existing research. To achieve this, the relevant research papers among academic journals registered with Korea Research Foundation are analyzed. According to the results, while the ordinary elderly tended to require macro level of intervention, the potential-risky elderly were inclined to need all of micro and moderate level of prevention efforts. Above all, secondary prevention must be more emphasized in moderate level. In the future direction of research, based on prevention strategies as stated above, it is recommended to entail discussion of what kind of a specific program and policy should be invented and how it should be operated.

This research will mainly focus on security issues in a university campus and delve into the risk factors and its characteristics due to the extreme polarization growth, and ultimately conduct research on legislative issues regarding safety & security management. A university campus is a miniature of the society, concentrated with human resources, material resources and knowledge information resources. It is also a region in which various underlying risk factors threaten these resources. However, due to the insensibility of danger and carefree indolence, these risk factors have been ignoring, leaving university campus amidst a "dead zone." Currently, a systematic and synthetic measures not only for safety inside the laboratory but also for the new type of crimes such as cyber crimes and motiveless crime due to extreme polarization, stress, uneasiness about the future, increase of mental illnesses, and drug abuse are urgently required. Therefore, I would like to introduce a legislative program in a crisis management perspective that can prevent universities from danger and protect the resources which would ultimately create a new security system.

Cronobacter muytjensii is an important foodborne pathogen as a potential risk in infant formula powder (IFP). To develop a new and sensitive method for the detection of Cronobacter spp. in IFP, an immunoglobulin G (IgG) specific for C. muytjensii (formerly known as Enterobacter sakazakii ATCC 51329) was developed. Further, an indirect noncompetitive enzyme-linked immunosorbent assay (INC-ELISA) was developed by using the anti-C. muytjensii IgG. As a result, this newly developed INC-ELISA method was found very sensitive for C. muytjensii with detection limit of $6.5{\times}10^3CFU/ml$ in pure culture and 1 cell/25 g of IFP. This INC-ELISA method also displayed excellent specificity for C. muytjensii showing no cross-reactivity with other strains of Cronobacter genus and 11 other foodborne pathogenic strains. These results show that the developed INC-ELISA method was very sensitive, efficient, and rapid for the detection of C. muytjensii. Hence, this method could be applied to the development of diagnostic kits for the rapid and easy detection of C. muytjensii.

The hazard assessment in which the potential hazard factors in the buildings are investigated and the scale of the hazard is analysed should be performed first in order to prevent personal and material damages due to building fire. In this study, the building fire hazard are assessed using 822-item checklist, for the qualitative evaluation of which the main factors are classified into 10 items, yielding 100 scale points with some weighting. It is shown that present model is applicable for the assessment model by actual assessment of existing building. Also the checklist is prepared in itemized questionnaire from easy assessment of building fire hazard. Therefore, the present model will be helpful for those working in fire prevention, who are suffering from the lack of manifest evaluation model for the fire prevention assessment so far in Korea.
