This study aimed to identify how social contact, depression, and anxiety influence suicidal ideation of the elderly related to general characteristics. The objects were 198 elderly living in Mungyeong-si, Gyeongsangbuk-do. The data were collected from 2, March to 15, April 2021. Collected data were analyzed by t-tests, ANOVA, Pearson's correlation coefficient, and multiple stepwise regression analysis using SPSS 24.0. Findings revealed 1) Pearson's correlation coefficient indicated significant association among social contact, depression, anxiety, and suicidal ideation 2) Multiple regression analysis showed that the influencing factors have 44.9% of explanation power in suicidal ideation of the elderly: depression(β=.430, p< .001), perceived financial status(β=-.198, p<.001), psychiatric treatment history (β=-.182, p=.002), and social contact (β=-.155, p=.007) in order. The conclusion of this study indicates that we need to pay interdisciplinary attention to the mental health of the elderly in the Covid-19 pandemic. Based on the findings, health professionals should provide elderly persons with comprehensive and appropriate management to prevent suicidal ideation upon factors. Additionally, there should be establishing a system to access and ensure social contact for the elderly.

The purpose of this study is to provide fundamental information for the development of new sex education image media through the analysis of those tools produced by Planned Parenthood Federation of Korea. Twenty three video tapes related to the sex education were analysed. The data were sampled on the basis of the sex education instructions for primary and secondary schools published by the Seoul Office of Education in 1996 and the list of sex education information composed by the Planned Parenthood Federation of Korea with the following requirements. 1) The education materials are oriented to the middle and high school students as well a juveniles and are being used in public health centers and schools. 2) The education materials are not confined to the single subject such as AIDS or contraception. Because this study is focused on the analysis of image media, an analysis method widely and effectively used in public media study was chosen. The frequency analysis and percentage treatment were done by an SAS program. The results of the study are as follows : 1. An analysis of the material structure type showed that the frequency of the following subjects in 15 video tapes, composed as drama and cartoon, had this decreasing orde : sex behavior, sex relation ships, sex health, human development, personal technique, and society and culture. 2. The eight tapes of explanation and counseling showed a different sequence from that of the drama and cartoon material, primarily treating human development with 5419 seconds (47.9%) of type. The following were also considered in decreasing order: at 2000seconds (17.6%) sex behavior, at 1366 seconds (12.1%) sex health, at 1240 seconds (11.0%) society and culture, at 667 seconds (6.0%) relation ships, and at 611 seconds (5.4%) personal technique. 3. In a thematic analysis those education materials dealing with human development show this frequency sequence: anatomic physiology, reproduction, and adolescence. In relation, ships the sequence is dates, love, marriage and vows, and family. For personal technique, it is expressed as asking for help, and an empnasis on moral values. For sex behavior, they focus on abstinence, the co-responsibility of sex behavior, the sexual response of the human, and sexual nightmares. For the sex health area, the focus is contraception with abortion and reproductive health following that. In society and culture diversity is considered. 4. An analysis of the differences in production and content between 1980s and 1990s was also done. For materials produced in the 1980s the frequency of the subjects follows this order: sex behavior, human development, relation ships, sex health, personal technique, and society and culture with sub subjects such as abstinence, dating, adolescence, anatomic physiology, reproduction, calls for help, and the sexual response of a human being. For materials produced in the 1990s, highest frequency was sex behavior, the same as the 1980s. The rest of the material follows this decreasing order: relationships, human development, sex health, society and culture, and personal technique with sub subjects such as dating, co-resposibility in sex behavior, abstinence, and love frequently considered.

Statement of problem : Today's market economy has been changed more and more to consumer concerned. It is owing to not only consumers ' rising standard of living and education, but also purchasers' easy accessibilities to products through various mass media. The consumer centered market system, where customer can choose items with diverse alternatives to satisfy their self esteem, is also applied to the field of medical business, and accelerated by an increasing income level of shoppers and introducing the whole nations' medical insurance system. Today, the medical industry has become competitive due to increasing number of medical institutions and medical personnel, and this offers wide choices to consumers in the medical market place. At this point of time, it is essential to survey on the primary factor of gratification for the patient in the Dental clinic, as well as on the problems and suggestions in medical service. Purpose : The analysis in this study shows essential factors and expected influential elements in satisfaction of the patient in the Dental Hopsital, and strategic suggestions for the provider of dental service, which can be of benefit to the prospective customer as well as can make improvement in the quality of dental treatment service. Material and method : This study had been researched by collecting and analyzing the organized questionnaires, which were filled in directly from 784 patients, who visit Dental Hospital, Yonsei University in Seoul, from January 23rd to April 15th. Result : It can be summarized like the followings. 1. The social and demographical peculiarities of respondents are as follows. Samples of gender and marital status are adequately extracted, but data on occupation and treatment are are under a bias toward students, undergraduates and graduate students, and orthodontics. 2. 74% of patients who answer the questionnaire were highly satisfied with the service of dental clinic in the section of overall satisfaction. 3. The survey result about specific service of dental treatment, within sections of independent variables, is like the followings; Patients are highly gratified with service system, kindness, explanation, explanation on expected waiting hours, reservation system, emergency measures, expert treatment, existence of knowledge of dentistry, size of hospital, disinfection, equipment and parking, but lowly satisfied with expense of treatment, preparatory hours for treatment, waiting hours, treatment hours and the period of subscription. 4. The correlation analysis showed that there is no significant linear relationship between the independent variables. 5. The probit regression analysis showed that 8 out of 34 independent variables explained the dependent variables at the level of 0.01. 6. It shows that 8 independent variables, which can affect customers 'satisfaction, are clearing up of inconvenience, service system, kindness, explanation, treatment hours per attendance, reservation system, existence of knowledge of dentistry, and contentment of equipment in the hospital. Conclusion : The consumer's satisfaction totally relies on subjective evaluations of customers. Providing appropriate service, which can meet the criteria for the customer who demands various wares, pursues luxury goods, and expects high quality of medical service, is essential to fulfill patients' satisfaction. Many medical institutions do their best to satisfy their customer, touch their consumer, and offer patience centered services, and it is also applied to the field of dentistry. Establishing brand new strategic managements and elevating the quality of dental service based on this survey are required to improve the satisfaction of patience in the Dental Hospital.

It is well understood that a paired comparison (paired t test) provides better precision than a group comparison (two-sample t test), when the pairing is effective (the variation within a pair is small). However, when the variation among the pairs is sufficiently small, the group comparison is likely to yield a better result. To get a statistical explanation of this, we examine the two methods through an analogy to one-way and two-way analysis of variance. We introduce a new measure, R statistic, which is the ratio of their confidence interval lengths, as a quantitative criterion for comparing the two methods. The distribution of the Rf statistic is described by t and F distribution functions. Through this characterization, we show that the paired comparison can be better than group comparison when the variation among the pairs is statistically significantly large.

The study used GIS methods to analyze a business district consisting of traditional markets and large-scale stores, to determine the level of support needed for small enterprises in an urban area of Changwon-si, Gyeongsangnam-do. Data gathered on the area was analyzed using GIS tools such as Kernel density, Network analysis, and Huff modeling. Traditional markets are concentrated in areas where large-scale stores are located, and data analyses show that the number of consumer'use of large-scale stores (157,071) was three times that of traditional markets (59,953). One explanation for these results is that the large-scale stores are located either in densely populated areas or are adjacent to the traditional markets. Therefore, standards and regulations are needed to support small enterprise business districts. In the future, the results of this study can be used as a reference for planning and supporting traditional market business districts.

In planning phase of Public Multi-Housing Projects, it is required to develop the methodology and criteria for fair cost prediction with influencing power from planning phase to occupancy phase. Many studies still have focused on the prediction of cost by multiple regression. However, there is no logical explanation about the influence of nonmetric variables for the prediction of cost in planning phase. Accordingly, this research pursues a cost prediction model including nonmetric variables for use in planning phase. There are 3 steps of this research : 1) Finding the factors influencing construction cost and assigning variables for a multiple regression. 2) Conducting a dummy regression analysis with nonmetric variables and model validation by comparing actual cost data. 3) Developing the ratio of RC structure cost to wall structure cost by using cost predection model. The results could establish cost prediction process including the influence of nonmetric variables and the ratio of RC structure cost to wall structure cost.

For effective conceptual teaching (or teaming) of physics, it needs to know more information about students＇ ideas related to specific topics. The purpose of this study was to investigate 6th grade students＇ various ideas about the actions of force, especially＇ the situation where force is being acted＇, and＇ the situation where force is not being acted＇, through the analysis of their ＇Typically-Perceived-Situation (TPS)＇. The TPSs of 152 6th grade students were collected with a drawing-and-explanation type questionnaire, and their TPSs about the action of force were categorized by the background, the subject, the object, the action, and the result of action, etc. It was found that most of students＇ ideas about ＇force is being acted＇ were related to the situation where the impact by or on human body caused to the change of position in familiar everyday life scene. Thus their ideas were strong related to human body, including sensual factors such as ＇pain＇. And it also was found that most of students＇ ideas about ＇force is not being acted＇ were in a strong relation to familiar everyday life situations there is no change of position because force was not given by a human body, or energy was not supplied. Most students thought that force is similar to energy which should be supplied from outside or generated by itself. These results suggest that the teaching strategies focused on familiar everyday life background including sensual factors and human body need to be explored in conceptual loaming of physics.

The purpose of this study was to identify the trends and risk of bias of research using time series analysis on health and welfare in Korea and to suggest a direction for future health and welfare research. The database searches identified 6,543 papers. Following the process for screening and selecting, a total of 91 papers were included in the systematic review. There has been a steady increase in the number of articles using time series analysis from 1987 to 2013. Time series analysis was applied in medicine and health science journals. The main goals were explanation and description. Most of the subjects were heath status and utilization of healthcare services. The main model used in the time series analysis was ARIMA followed by time series regression. The data were gathered from various sources, including the national statistical office and government agencies. For assessing risk of bias, some studies were found to have inadequate sample sizes or showed no time series graphs and plots. These findings suggest greater widespread utilization of time series analysis in the field of health and welfare and to use the appropriate analysis methods and statistical procedures to obtain more reliable results to improve the quality of research.

This study attempted to test the causal effect of structural characteristics of metropolitan neighborhoods on crime, based on the ecological model of crime explanation. To this end, a Negative Binomial Regression analysis was performed for Seoul's 424 Dong Districts. Results showed that the incidence of homicide increases as much as the scales of economic disadvantage, family disruption, and commercial land use go worse. It suggested that family integrity is one of the most strong and consistent factors that could deter crime in neighborhood's contexts. Economic disadvantage and commercial land use were also critical targets as crime-generating factors. Reasoning with the results of past studies implied that neighborhood-specific approaches need to be developed for effective crime prevention. Although a few limitations could raise a caveat against such interpretation of the results, the value of this research would not be simply denied as the first attempt to utilize all Dong districts of Seoul. It is expected that this study contributes to activating Dong level research and developing effective crime control policy.
