In succession of the previous works, seismo-acoustic analysis was conducted to collect ground truth events and to discriminate surface explosions from natural earthquakes in the Korean Peninsula for 2004. In this period, total 510 seismo-acoustic events corresponding to 10.8 percent of total seismic events occurred in and near the Korean Peninsula were analyzed and discriminated as artificial surface explosions. Events distribution of the seismo-acoustic events in 2004 is similar to the previous results of 1999-2003. And newly determined seismo-acoustic events were added to the surface explosions database. To extend infrasound detection capability, Korea Institute of Geoscience and Mineral Resources (KIGAM) and Southern Methodist University (SMU) installed new seismo-acoustic array (BRDAR) in Baekryoung Island last November, 2004. The array configuration and design is nearly same to previous seismo-acoustic arrays CHNAR, KSGAR, a triangular 1 km aperture. BRDAR consists of 5 short period vertical seismometers (GS-13) in seismic vaults and 13 microbarometers (Chaparral Model 2). Preliminary analysis using data collected from BRDAR shows an extension of infrasound detection capability to western part of the Korean Peninsula. Also, multiple observations of infrasound at BRDAR and other arrays gave an opportunity to localize sound source regions.

Stochastical independence is separated into two. One can be intuitively judged and the other is not. Independence is a concept based on assumption. However, It is defined as multiplication rule and it has produced extension of concept. Analysis on this issue is needed, assuming the cause is on the intersection sign which is used for both simultaneous events and compatible events. This study presented the extension process of independence concept in detail and constructed twofold interpretation of simultaneous events and compatible events which use the same sign $P(A\cap{B})$ with Pierce Semiotics.

This study aims to examine the properties of using bakeries based on demographic variables and repurchase intention and recommendation intention according to participation rates in promotional events. First, demographic characteristics and frequency of using bakeries were analyzed. Second, crosstabulation analysis on usability was conducted according to demographic variables. Third, effects of participation rates in promotional events on repurchase intention and recommendation intention were examined. This study could provide the reasons why bakeries should do promotional events, showing their effects on sales. Surveys were conducted with the students of the culinary department and bakery customers to investigate the influence on repurchase intention and recommendation intention according to participation rates in promotional events. As a result, both repurchase intention and recommendation intention showed a significant result. Also, the study aims to improve understanding by analyzing demographic variables on the properties of using bakeries(frequency in use of bakeries, purchase type, bakery type that is preferred, a time slot being made a purchase, objects of purchase, and purchasing price per person) and create data to help the management of a bakery.

The purpose of this study was to investigate the trend of the room where activities of daily living and family events(activities of non-daily living) were performed with time. Research data was collected in 1992 and 2002 from households living in Seoul that have university student by using questionnaire surveys. Data was analyzed using the SPSS package program. The major findings of this study were as follows: 1) Living room was a multi-purpose space for various activities: receiving guests, family communication, ironing, sewing and dining as well as a kitchen. Anbang(master bed room) is the place where the couple sleeps. The room's purpose has changed from a multi-purpose space to a private space. 2) Most of the families performed the majority of the family events in the living room and Anbang. In the past, traditional events and birthday parties were performed in Anbang, but currently the trend has changed. This would mean that with time the majority of the family events were held in the living room. 3) Space planning is required to meet the dwellers' use of living room and Anbang.

This study was on low-income female earners, and focused on family life events, social support, and support from children which low-income female easers had experienced. It also examined how family life events, social support, and support from the children affected the level of life satisfaction of the low-income age in the Seoul metropolitan area. The analysis of the data showed the following results: 1. The low-income female roamers experienced finance and business strains more than other family life events. The significant family life events that affected their life satisfaction were intra-family strains, finance and business stains, and illness and family care stains. 2. The level of social support was average. The low-income female earners reported that their relatives had provided the largest amount of support among their social network; however, only support from their friends affected their life satisfaction. Emotional support was the common support type which low-income female easers had received. 3. The perceived level of support from children was high, and it was the most significant variable that affected the life satisfaction of the low-income female eamers.

With the continual development of genetically modified (GM) crops, it has become necessary to develop detailed and effective molecular characterization methods to select candidate events from a large pool of transformation events. Relative to traditional molecular analysis methods such as the polymerase chain reaction (PCR) and Southern blot hybridization, next generation sequencing (NGS) technology for whole-genome sequencing of complex crop genomes had proven comparatively useful for in-depth molecular characterization. In this study, four transformation events, including one in Bacillus thuringiensis (Bt)-resistant rice, one in resveratrol-producing rice, and two in beta-carotene-enhanced soybeans, were selected for molecular characterization. To merge NGS analysis and Southern blot-hybridization results, we confirmed the transgene insertion sites, insertion construction, and insertion numbers of these four transformation events. In addition, the read-coverage depth assessed by NGS analysis for inserted genes might provide consistent results in terms of inserted T-DNA numbers in case of complex insertion structures and highly duplicated donor genomes; however, PCR-based methods can produce incorrect conclusions. Our combined method provides an effective and complete analytical approach for whole-genome visual inspection of transformation events that require biosafety assessment.

Purpose : The purpose of this study was to identify the moderating effects of emotional intelligence on the relationship between traumatic events and turnover intention among nurses working in intensive care units (ICUs). Method : In this predictive correlation study, the convenience sample included 133 ICU nurses. Data were collected using an online, structured self-report survey. The collected data were analyzed by descriptive statistics, an independent t-test, an analysis of variance, Pearson's correlation coefficient, and a hierarchical multiple regression analysis using SPSS/WIN 25.0. Results : The most frequently experienced traumatic events in ICUs were "nursing patients with abnormal behavior, including shouting and delirium," "end-of-life care," and "nursing patients with a risk of disease transmission, including AIDS and tuberculosis." The moderating effect of emotional intelligence was found to be statistically significant on the relationship between traumatic events and turnover intentions (𝛽=-0.15, p =.029). Conclusion : Intervention to improve the emotional intelligence of ICU nurses can be a salient strategy to reduce turnover intention resulting from traumatic events.

In general, an internal fire events probabilistic safety assessment (PSA) model is quantified by modifying the pre-existing internal event PSA model. Because many pieces of equipment or cables can be damaged by a fire, a single fire event can lead to multiple internal events PSA initiating events (IEs). Consequently, when the fire events PSA model is quantified, inappropriate minimal cut sets (MCSs), such as duplicate MCSs, may be generated. This paper shows that single quantification of a hypothetical single-top fire event PSA model may generate the following four types of inappropriate MCSs: duplicate MCSs, MCSs subsumed by other MCSs, nonsense MCSs, and MCSs with over-counted fire frequencies. Among the inappropriate MCSs, the nonsense MCSs should be addressed first because they can interfere with the right interpretation of the other MCSs and prevent the resolution of the issues related to the other inappropriate MCSs. In addition, we propose a resolution process for each of the issues caused by these inappropriate MCSs and suggest an overall procedure for resolving them. The results of this study will contribute to the understanding and resolution of the inappropriate MCSs that may appear in the quantification of fire events PSA models.

Purpose: The present study investigated experiences of traumatic perinatal events, the provision of related education, and educational needs of nurses working in the labor and delivery room (LDR). Methods: Nurses working in the LDRs of six institutions and two nurse portal sites were invited to participate in the survey, delivered on paper or online. The data were collected from October 1 to November 25, 2022. Data from 129 nurses were analyzed using frequency, the chi-square test, the Fisher exact test, the t-test, and analysis of variance. Results: Virtually all participants (98.6%) reported having experienced at least one traumatic perinatal event (dystocia, postpartum hemorrhage, neonatal congenital anomalies, severe maternal or neonatal injury, stillbirth, and maternal or neonatal death) while working in the LDR. The most shocking traumatic perinatal event experienced was the maternal or neonatal death (40.3%), but 24.8% of participants did not recall ever receiving education on the topic. About 63% of participants experienced traumatic perinatal events within a year of working in the LDR. The average score for education needs regarding traumatic perinatal events was 3.67±0.37 out of 4, and participants preferred simulation education as the most effective educational method. Conclusion: Since most of the participants had experienced various traumatic perinatal events in the early stages of working in the LDR and expressed a high level of need for education on traumatic perinatal events, it is necessary to provide more effective stimulation education programs in the early period of work in the LDR.
