Objectives: This study aimed to identify regional differences in the high-risk drinking rate among yearly alcohol users in Korea and to identify relevant regional factors for each quintile using quantile regression. Methods: Data from 227 counties surveyed by the 2017 Korean Community Health Survey (KCHS) were analyzed. The analysis dataset included secondary data extracted from the Korean Statistical Information Service and data from the KCHS. To identify regional factors related to the high-risk drinking rate among yearly alcohol users, quantile regression was conducted by dividing the data into 10%, 30%, 50%, 70%, and 90% quantiles, and multiple linear regression was also performed. Results: The current smoking rate, perceived stress rate, crude divorce rate, and financial independence rate, as well as one's social network, were related to the high-risk drinking rate among yearly alcohol users. The quantile regression revealed that the perceived stress rate was related to all quantiles except for the 90% quantile, and the financial independence rate was related to the 50% to 90% quantiles. The crude divorce rate was related to the high-risk drinking rate among yearly alcohol users in all quantiles. Conclusions: The findings of this study suggest that local health programs for high-risk drinking are needed in areas with high local stress and high crude divorce rates.

The Online business model for purchasing agent service is getting more popular. However, consumers perceive more risk when buying products from foreign online purchasing agents (FOPA) than from common online sellers (COS). This study focuses on finding out how consumers manage risk when they perceive risk and what different risk-reliever strategies they use when buying from high-risk FOPA and low-risk COS. This study has proved the following two. First, when consumers perceive risk at online purchasing, they tend to select risk-reliever strategies, such as the use of communication media, online assurance mark, seller's record, and secure payment to mitigate risk. With the application of those risk-reliever strategies, they built trust with the seller. Second, risk-perception of FOPA influences usage of communication media and check of online assurance mark more strongly than that of COS. On the contrary, risk-perception of COS influences the check of seller record more strongly than that of FOPA. This study helps to explain why FOPA is proliferating, despite its inherent high risk due to the fact that buyers and sellers are separated in time and space and that buyers and sellers have different social and cultural backgrounds. This study also helps managers of E-commerce to relieve consumer's risk-perception and to build trust.

In the current era of low-birth rate in Korea, it is important to improve our neonatal intensive care and to establish an integrative system including a regional care network adequate for both high-risk pregnancies and high-risk newborn infants. Therefore, official discussion for nation-wide augmentation, proper leveling, networking, and regionalization of neonatal and perinatal care is urgently needed. In this report, I describe the status of neonatal intensive care in Korea, as well as nationwide flow of transfer of high-risk newborn infants and pregnant women, and present a short review of the regionalization of neonatal and perinatal care in the Unites States and Japan. It is necessary not only to increase the number of neonatal intensive care unit (NICU) beds, medical resources and manpower, but also to create a strong network system with appropriate leveling of NICUs and regionalization. A systematic approach toward perinatal care, that includes both high-risk pregnancies and newborns with continuous support from the government, is also needed, which can be spearheaded through the establishment of an integrative advisory board to propel systematic care forward.

Purpose: The purpose of this study was to develop a tool to assess the severity of illness in high risk newborns. Method: The research design was a methodological study. The tool was developed in 4 stages: first, preliminary items were developed based on a questionnaire about the severity of illness index that was given to 8 health professionals in Neonatal Intensity Care Units (NICU) second, a panel of specialists reduced the preliminary items using 3 validity tests; third, final items were selected from the results of a pre-test. Finally, from July 2005 to May 2006, reliability and validity were tested with a sample of 160 high risk newborns admitted to the NICU. Results: The final tool to identify the severity of illness index in high risk newborns consisted 39 items and Cronbach's alpha coefficient for internal consistency was .922. Using factor analysis, 4 factors were extracted and these factors explained 54.451% of the total variance. Conclusion: The instrument for assessing the severity of illness in high risk newborns developed in this study was identified as a tool with a high degree of reliability and validity. In this sense, this tool can be effectively utilized for assessing and implementing care for high risk newborns.

Piracy cases have been increasing globally since 2007. Recently, the waters of West Africa including the Gulf of Guinea, emerged as the most dangerous areas in the world. To prevent piracy damage to ships and crew, the Korean government amended the Piracy Damage Prevention Act on August 17, 2021 to newly define the risk area and the high-risk area for piracy. It also established the legal framework for restricting the entry of ships into such high-risk areas. This study aims to discuss and present a plan for establishing risk areas and high-risk areas for piracy to be noticed by the government in accordance with the amended Act. In this study, international piracy trends, international response measures and the status of international high-risk areas were investigated and analyzed, the matters to be considered to designate high-risk areas were identified. It is expected that the resulting information on high-risk areas for piracy can be utilized not only for the development of government policies on the prevention of piracy, but also as basic academic data.

Background: Several risk factors leading to malignant transformation of hydatidiform moles have been described previously. Many studies showed that prophylactic chemotherapy for high risk hydatidiform moles could significantly decrease the incidence of malignancy. Thus, it is essential to discover a breakthrough to determine patients with high risk malignancy so that prophylactic chemotherapy can be started as soon as possible. Objectives: Development of a scoring system of risk factors as a predictor of hydatidiform mole malignant transformation. Materials and Methods: This research is a case control study with hydatidiform mole and choriocarcinoma patients as subjects. Multiple logistic regression was used to analyze the data. Odds ratios (OR), attributable at risk (AR : OR-1) and risk index ($ARx{\beta}$) were calculated for develoipment of a scoring system of malignancy risk. The optimal cut-off point was determined using receiver operating characteristic (ROC) curve. Results: This study analyzed 34 choriocarcinoma cases and 68 benign hydatidiform mole cases. Four factors significantly increased the risk of malignancy, namely age ${\geq}35$ years old (OR:4.41, 95%CI:1.07-16.09, risk index 5); gestational age ${\geq}$ 12weeks (OR:11.7, 95%CI:1.8-72.4, risk index 26); uterine size greater than the gestational age (OR:10.2, 95%CI:2.8-36.6, risk index 21); and histopathological grade II-III (OR:3.4, 95%CI:1.1-10.6, risk index 3). The lowest and the highest scores for the risk factors were zero and 55, respectively. The best cut-off point to decide high risk malignancy patients was ${\geq}31$. Conclusions: Malignant transformation of hydatidiform moles can be predicted using the risk scoring by analyzing the above four parameters. Score ${\geq}31$ implies high risk patients so that prophylactic chemotherapy can be promptly administered for prevention.

Objectives: In Korea, the proportion of deaths due to alcohol is estimated at 8.9%, far exceeding the global estimate of 3.8%. Therefore, this study was performed to examine the factors associated with low-risk, moderate-risk, and high-risk drinking patterns in Korean adults and to identify target populations for prevention and control of alcohol-related diseases and deaths. Methods: We analyzed data from 230 715 Korean adults aged 19 years and older who participated in the 2009 Korean Community Health Survey. Multinomial logistic regression analysis was used to examine associations between socio-demographic and health-related factors and patterns of alcohol use. Results: A substantially larger proportion of men than women engaged in high risk (21.2% vs. 3.4%) and moderate-risk alcohol use (15.5% vs. 8.2%). In both sexes, moderate- and high-risk uses were associated with younger age, higher income, being currently employed, smoking, being overweight/obese, and good self-rated health. Conclusions: Given the large proportion of the population that is engaging in moderate- and high-risk drinking and given the social norms that support this behavior, public health policies and campaigns to reduce alcohol consumption targeting the entire population are indicated.

Purpose: The incidence of high-risk pregnancies is increasing in Korea as the birth age increases due to late marriage. Maternal-fetal attachment is an important factor that affects children even after childbirth, but it is difficult for high-risk pregnant women to form maternal-fetal attachment. The current study aimed to explore whether taegyo practice (i.e., pregnant women's efforts for fetal good growth and development), self-esteem, and social support influenced the degree of maternal-fetal attachment in women with high-risk pregnancies. Methods: The participants included 226 pregnant Korean women at ≥20 gestational weeks, hospitalized with 15 high-risk pregnancy conditions as defined by the Ministry of Health and Welfare. Recruitment via convenience sampling was done at four sites in Busan, Korea. Surveys were distributed and collected from February 1 to 28, 2022. Data analysis was conducted using descriptive statistics, the t-test, one-factor analysis of variance, Pearson correlation coefficients, and hierarchical multiple regression. Results: On average, participants were 33.97±4.23 years of age and at 31.65±6.23 gestational weeks. Preterm labor (35.4%) and gestational diabetes (21.0%) were the most common high-risk conditions. Maternal-fetal attachment was positively correlated with taegyo practice (r=.70, p<.001), self-esteem (r=.53, p<.001), and social support (r=.53, p<.001), all with statistical significance. Taegyo practice (β=.50, p<.001) and social support (β=.17, p=.030) explained 53% of variance in maternal-fetal attachment in women with high-risk pregnancies. Conclusion: Nurses caring for women with high-risk pregnancies during hospitalization can use these findings by promoting taegyo practice and enhancing social support to increase maternal-fetal attachment.

Since the 1980s, the number of large space buildings in Korea has consistently been increasing due to large scale international competitions such as the Olympics and the World Cup, demands for environmental improvement, and development of structural systems. Due to these reasons, this paper conducted a comparative analysis on terrorism risk factors of large space structure and skyscrapers in Korea. The results suggest that the total risk level of high-rise and large space structure was "medium level risk" and that the terrorism risk level for large space structure was as high as that for high-rise buildings. As it relates to the risk levels depending on scenarios, terrorism risks to large space structure were higher than high-rise buildings in the "internal explosion" and "internal intrusion" categories. And the results of analyzing explosion-related scenarios except for CBR suggest that terrorism risks to large space structure were highest when it comes to Internal-Explosive followed by Internal-Intrusion and Explosive-Zone I; and the results showed a regular pattern. On the other hand, in the case of high-rise buildings, terrorism risks were highest in Internal-Explosive followed by Explosive-Zone I and Explosive-Zone II; and the results showed an irregular pattern.
