The purpose of this study was to identify the factors that could overcome the crisis and adversity of the nursing care provider through understanding the effect of job adaptation on the turnover intention of the nursing care provider and to contribute to the various problems of the nursing care provider in the long term. In order to confirm this as an empirical research task, risk factors and protection factors, general characteristics of the survey subjects, job adaptation and turnover intention were selected, and the risk factors and protective factors of caregivers' As a mediator. So Seoul. The results of the questionnaire survey were as follows: 291 caregivers in the elderly medical welfare facilities in Gyeonggi area. First, as the relationship between the risk factors and protective factors of occupational caregivers and occupational adaptation were more severe, the higher the maladjustment of the workplace culture, the more the job satisfaction and organizational commitment were adversely affected. The emotional support, The higher the information support, the more satisfied and satisfied the job. Second, the relationship between the risk factors of the caregiver and the protective factors and the turnover intention, the higher the conflict of caregivers, the more unstable the workplace, the more difficult it is to adapt to work culture, Respectively. Finally, as a result of verifying the mediating effect of occupational adaptation on the relationship between risk factors and protective factors and turnover intention of caregivers, job satisfaction, which is a sub-factor of job adaptation, It is shown that they play mediating roles only in the relationship between stress and turnover intention, and do not play a mediating role in the relationship between protective factor self - efficacy and social support and turnover intention. In other words, if caregivers feel satisfaction about their job, they can be less stressed on their jobs, improve their self-efficacy, and have a positive attitude toward social support. Also, it was found that the more the caregiver 's immersion into the organization, the less job stress and turnover intention decreased, but the self - efficacy and social support perception were not influenced. Based on this, the director of the facility should strive to stabilize the operation of the facility and provide high-quality services by seeking ways to improve conflict resolution and adaptation to the workplace culture so that nursing care workers can adapt to their work. And it is required to develop active management strategies and institutional support for improving job satisfaction and organizational commitment of caregivers.

Objectives: This study examined the personal, interpersonal and community factors related to food sufficiency and variety among Korean adults using data from the 2017 Community Health Survey. Methods: A total of 228,310 adults aged ≥ 19 years were classified into three groups: food sufficiency with variety, food sufficiency without variety and food insufficiency. Personal factors included sociodemographic characteristics, health behavior and health status. Interpersonal factors included social networking and social activities, and community factors included safety, natural environment, living environment, availability of public transportation and health care services. The association of food sufficiency and variety with interpersonal and community factors was assessed using multivariable logistic regression analyses. Results: Of the total sample, the food-sufficiency-without-variety group and food insufficiency group accounted for 31.5% and 3.2%, respectively. The sociodemographic factors associated with food insufficiency and non-variety were women, ≥ 65 years of age, with low education level, low household income, unemployed, single, and living in areas of small population sizes. There were significant differences in health behavior and health status, interpersonal and community factors among the three groups. Multivariable logistic regression analyses conducted after adjusting for confounding factors showed that lack of social networking and social activities and lower satisfaction derived from community environments were associated with the risk of food insufficiency and non-variety. Conclusions: Our results showed that interpersonal and community factors as well as personal factors were related to food sufficiency and variety. Therefore, public policies to help build social networks and participation in social activities, and improve community environment are needed together with food assistance to overcome the problems of food insufficiency and non-variety.

Forecasting of box office performance after a film release is very important, from the viewpoint of increase profitability by reducing the production cost and the marketing cost. Analysis of psychological factors such as word-of-mouth and expert assessment is essential, but hard to perform due to the difficulties of data collection. Information technology such as web crawling and text mining can help to overcome this situation. For effective text mining, categorization of objects is required. In this perspective, the objective of this study is to provide a framework for classifying films according to their characteristics. Data including psychological factors are collected from Web sites using the web crawling. A clustering analysis is conducted to classify films and a series of one-way ANOVA analysis are conducted to statistically verify the differences of characteristics among groups. The result of the cluster analysis based on the review and revenues shows that the films can be categorized into four distinct groups and the differences of characteristics are statistically significant. The first group is high sales of the box office and the number of clicks on reviews is higher than other groups. The characteristic of the second group is similar with the 1st group, while the length of review is longer and the box office sales are not good. The third group's audiences prefer to documentaries and animations and the number of comments and interests are significantly lower than other groups. The last group prefer to criminal, thriller and suspense genre. Correspondence analysis is also conducted to match the groups and intrinsic characteristics of films such as genre, movie rating and nation.

Purpose: This study aims to provide important methods to increase egg usage eggs in communal food services, based on the knowledge and awareness of the dietician. Methods: A survey on 200 dieticians in various aspects, such as egg purchase, utility, importance of egg dishes and allergy awareness was conducted. Result: Dieticians' highest consideration in purchasing eggs were cost (41.5%) and food safety certification (41.0%); the 88.6% of purchases were general egg. The most inconvenient issues in the purchase were inability to confirm freshness (42.0%), frequent breakage (23.5%) and inconvenience in shell disposal (18.5%). During the process of cooking, cracking egg shells (49.5%) and disposal of shells (14.0%) were marked as the major inconveniences. When questioned on intention to purchase liquid and powder eggs to overcome the shell disposal inconvenience, 64% answered no, with distrust in food safety (44.5%) being the major concern. The frequency of using eggs as the main ingredient was 1~2 times per week, with 49.0%. Food service customers favored rolled omelet (36.7%) and steamed egg (20.6%), and the most used utensil was the frying pan (56.5%). When important factors in egg dishes, namely diverse menu, taste, nutrition, consumer satisfaction and allergic reaction were surveyed, most answered that all 5 factors were important. Conclusion: For increasing egg dish inclusions in communal food service, the safety assurance, increase in liquid and processed egg use, and supply of cooking utilities are necessary.

For the past three decades, more than a thousand of genetic studies have been performed to find out the genetic variants responsible for the risk of asthma. Until now, all of the discovered single nucleotide polymorphisms have explained genetic effects less than initially expected. Thus, clarification of environmental factors has been brought up to overcome the 'missing' heritability. The most exciting solution is epigenesis because it intervenes at the junction between the genome and the environment. Epigenesis is an alteration of genetic expression without changes of DNA sequence caused by environmental factors such as nutrients, allergens, cigarette smoke, air pollutants, use of drugs and infectious agents during pre- and post-natal periods and even in adulthood. Three major forms of epigenesis are composed of DNA methylation, histone modifications, and specific microRNA. Recently, several studies have been published on epigenesis in asthma and allergy as a powerful tool for research of genetic heritability in asthma albeit epigenetic changes are at the starting point to obtain the data on specific phenotypes of asthma. In this presentation, we mainly review the potential role of DNA CpG methylation in the risk of asthma and its sub-phenotypes including nonsteroidal anti-inflammatory exacerbated respiratory diseases.

This study analyzes the regional industrial policies of Daegu based on previous discussions on the concepts and characteristics of regional industrial policies in Korea. Because of the institutional limitations of regional industrial policies in Korea, the industrial policies of Daegu are more government-led in planning and promoting industrial development. In addition, regional industrial policies have been established and executed not as regional policies but as part of sectional policies, and are not properly connected to other regional development policies. What is more, the step-by-step objectives of industrial policies are not defined clearly and, as a result, the means of the policies are not specific. In order to overcome these problems, there should be a paradigmatic transition in making regional industrial policies, which reflects not only economic factors but also the social and cultural factors of the region. Moreover, place-based policies should be planned and promoted that categorize areas subject to the policies through comprehended analysis of regional industrial environment and combine means by section.

Prior research on the fishery village tourism has mainly focused on the development and activities in the field, but lacking in strategic approaches. To overcome such a limitation, this study intends to measure visitors' authenticity on Gijang Anchovy Festival, test reliability and validity of the measurement items, and to identify the relationships among variables by a regression analysis of visitors' satisfaction. Authenticity means the value of existence. The types of tourism in fishing villages have been classified as fishery tourism, resource tourism and ecotourism and each of them has its own authenticity. Based on previous research, this study classified it into three factors such as objective authenticity, experiential authenticity and inauthenticity. To analyze the current situation of Daebyeon Anchovy Festival, measurement scales were developed and survey was conducted on the visitors for the three days from April 20 to 23, 2007. A total of 211 questionnaires were distributed and 208 were collected, The questionnaire contains 25 items on authenticity and 4 items on satisfaction and all the items were measured on the 7 Likert scale. It also has 8 items on demographic characteristics. On the test of reliability and validity of the authenticity, 24 items were used, Cronbach's was 0.7 and correlation was higher than 0.3. Factors of objective authenticity, experiential authenticity and inauthenticity were drawn from the factor analysis, which means that the 24 items may be used to measure authenticity of fishery festivals. The findings show that the evaluation score was 4.89 for objective authenticity, 4.36 for experiential authenticity, and 4.24 for inauthenticity. On the test of the hypotheses, the path coefficients were estimated 0.087 for objective authenticity, 0.202 for experiential authenticity and 0.503 for inauthenticity on the visitors' satisfaction. This suggests some meaningful marketing strategies for Gijang Anchovy Festival. First of all, the anchovy festival should focus on motivating visitors to revisit the festival by identifying individual traits, making a pleasant festival oriented toward family visitors, and providing more experience programs about anchovy.

The purpose of this longitudinal case study is to shed light on the reliability problems of IS performance evaluation by analyzing the discrepancy between ex ante evaluation in 2011 and ex post evaluation in 2012. Through an information system development project of a public enterprise, the gap between ex ante and ex post evaluation was ascertained and the causes as to why such gap occurs and the success factors that can solve the problems were derived. The ex ante evaluation of IS performance was performed based on both IS success model and BSC model and the ex post evaluation was carried out at the time after the target system has been built up by applying the evaluation measures and process that are similar to the ex ante evaluation. In the ex ante evaluation the business performance improved by the target system was estimated to 18.2%. On the other hand, it was seen as being low at 15.2% in the ex post evaluation and the differences were found to be statistically significant in 6 out of 10 measures. The reasons as to why such gap occurs were diagnosed as being of 2 types : (1) changes in the evaluation psychology according to the differences in the evaluation objectives; and (2) excessive expectation levels of the target system that is formed at the time of the ex ante evaluation. In other words, the users who have excessive expectations tend to overestimate in the ex ante evaluation and, in the ex post evaluation, tend to underestimate lower than the actual performance mainly due to disappointment on the results that do not meet the early expectations. As solutions to overcome the reliability problem of ex ante evaluation, 3 factors were derived : (1) the temperance of excessive expectation levels of the users; (2) a clear definition of the scope and functionality of the target system; and (3) actual commitments for the evaluations of IT performance.

Objectives Many studies have suggested different neurobiological findings and clinical courses in alcoholism. Recently, subtyping in alcohol dependence has become essential to overcome the heterogeneity of patients. Among several criteria of subtypes, Lesch's typology is proposed to integrate biological, social, and psychological factors. This review provides neurobiological findings and treatment-responses of alcohol dependence according to Lesch's typology. Method We searched the international published medical literature using the search terms 'Lesch's typology' and 'alcohol dependence' and using the limits 'human'. Results We identified 17 studies with subjects of alcohol dependence according to Lesch's typology. Conclusion They indicated that each subtype of Lesch's typology can have specific neurobiological factors and different clinical responses as follows. Lesch's subtype 1 is characterized by severe withdrawal symptoms and associated with elevated glutamate and homocysteine. Lesch's subtype 2 is defined by individuals who drink alcohol as self-medication for anxiety. Their craving has significant positive correlations with prolactin, leptin level, or intake-volume (vasopressin). Lesch's subtype 4 is related to cerebral dysfunction and associated with increased glutamate and left-handedness. Clinical trials showed that naltrexone was effective in Lesch's subtype 3 and 4 patients, while acamprosate was effective in the subtypes 1 and 2.

In recent times, fuel economy enhancement and environmental regulation compliance have become the main topics of interest in the automobile industry. Electric vehicles are desirable alternatives to the existing cars that employ internal combustion engines. Specifically, electric vehicles are equipped with inverters, motors, and a gearbox instead of engines and transmission mechanisms. The gearbox is a key component, used to transmit power from the electric motor to the wheel. Therefore, the design of the gearbox is critical. However, most engineers design gears based only on their experience because no standards pertaining to the design factor exist, other than those for the gear ratios. To overcome this problem, the structural stabilities must be examined considering the design factors of the gears. In this study, we considered the module and number of teeth as the main factors. The constraints corresponded to the final gear ratio and fixed distance between each axle of the shafts. Moreover, a structural analysis was conducted, and the variation trend of the maximum equivalent stress against changes in the gear module and number of teeth was examined. By performing such an analysis, the structural stability in the design of a gear system could be effectively investigated.
