The purpose of this study is to investigate the effect of health behavioral factors such as general characteristics, lifestyle and disease characteristics on depression in patients with chronic diseases. To this end, among 7,359 people who participated in the 8th National Health and Nutrition Survey conducted from 2019 to 2020, chi-square test analysis between health behavior factors and depression for 1980 people aged 19 years or older with chronic diseases and no missing values in the basic survey items was performed. After that, binary logistic regression analysis was performed with the factors that were significant as independent variables. As a result of the analysis, depression was 1.49 times higher in women than men (CI: 1.086~2.044), and was 1.828 higher in smokers than in non-smokers (CI: 1.285~2.561). And the higher the income level, the lower the depression. In particular, the odds ratio was 28.034 (CI: 13.132~59.849) in 'not stressful' versus 'very stressed', which had the greatest effect when the intensity of stress was very high. And the influence of subjective health cognition and sleeping hours was also relatively high. This study is meaningful in that it identified the priority of health behavior factors that should be practiced to improve depression in patients with chronic diseases. And since the number of comorbidity was not significant in the occurrence of depression, it would be necessary to identify the extent to which each type of chronic disease affects depression and to suggest policy alternatives tailored to each patient group.

In recent years, turnover intention among employees in China's banking industry has surged due to internal and external environmental pressures. This surge surpasses those occurring in other sectors. This rising trend in employee turnover has resulted in reducing employee turnover becoming a critical priority for banks in their ongoing development. Traditional leadership styles have proven inadequate for addressing this issue, requiring a shift towards more effective management approaches. This study explores the potential of servant leadership, a management style that prioritizes employees' needs, supports their development, and motivates them to realize their potential, as a means to mitigate rising turnover intentions. The research focuses on employees in the Chinese banking sector so as to examine the impact of the servant leadership management approach on their turnover intentions. Job crafting is investigated as a mediating variable, while stress mindset is assessed as a moderating variable. Data were collected from 401 valid questionnaires across 62 teams, comprising 62 leaders and 339 employees. Hypotheses were tested using SPSS 26.0 and HLM 6.0. The findings reveal that: (1) servant leadership significantly reduces turnover intentions; (2) job crafting mediates the relationship between servant leadership and turnover intentions; and (3) stress mindset positively moderates the influence of job crafting on turnover intentions. This study provides empirical evidence supporting the relationship between servant leadership and turnover intentions. The study's findings offer valuable insights into how to enhance employee management practices. It also discusses the theoretical and practical implications of integrating servant leadership into the banking sector, highlights the study's limitations, and proposes directions for future research.

The purpose of this study was to investigate the demand and use of fresh-cut produce in school foodservice and restaurant industries. The subjects of this survey study were 200 school nutritionists and 70 cooks or managers in the restaurant industry nationwide. The data were collected by means of self-administered or e-mail questionnaires. Data analysis was completed using the SPSS window (ver. 12.0) program including frequency, $\chi^2$-test and t-test. Survey questions assessed the general characteristic of respondents, and the supply, use, and demand of fresh-cut produce in school foodservice and restaurant industries. Over 74% of the subjects have used fresh-cut produce. Most of the school foodservice (84.0%) kept fresh-cut produce for one day, while restaurant industry (28.3%) kept them up to three days. The nutritionists of school foodservice and managers of restaurant industry considered origin and date of production as the most important factor, respectively, when fresh-cut produce were being used. Fresh-cut root vegetable, such as potato and carrot was used mostly. The main reason not to use the fresh cut produce was due to the distrust of the fresh-cut produce safety in school foodservice and cost in restaurant industry. The main problem in fresh-cut produce use was the need of rewashing (29.9%) in school foodservice and irregular size (39.0%) in restaurant industry. These results indicate that the quality standard and size specification must be prepared with production guideline of safe fresh-cut produce.

People are nowadays creating a tremendous amount of data on Social Network Service (SNS). In particular, the incorporation of SNS into mobile devices has resulted in massive amounts of data generation, thereby greatly influencing society. This is an unmatched phenomenon in history, and now we live in the Age of Big Data. SNS Data is defined as a condition of Big Data where the amount of data (volume), data input and output speeds (velocity), and the variety of data types (variety) are satisfied. If someone intends to discover the trend of an issue in SNS Big Data, this information can be used as a new important source for the creation of new values because this information covers the whole of society. In this study, a Twitter Issue Tracking System (TITS) is designed and established to meet the needs of analyzing SNS Big Data. TITS extracts issues from Twitter texts and visualizes them on the web. The proposed system provides the following four functions: (1) Provide the topic keyword set that corresponds to daily ranking; (2) Visualize the daily time series graph of a topic for the duration of a month; (3) Provide the importance of a topic through a treemap based on the score system and frequency; (4) Visualize the daily time-series graph of keywords by searching the keyword; The present study analyzes the Big Data generated by SNS in real time. SNS Big Data analysis requires various natural language processing techniques, including the removal of stop words, and noun extraction for processing various unrefined forms of unstructured data. In addition, such analysis requires the latest big data technology to process rapidly a large amount of real-time data, such as the Hadoop distributed system or NoSQL, which is an alternative to relational database. We built TITS based on Hadoop to optimize the processing of big data because Hadoop is designed to scale up from single node computing to thousands of machines. Furthermore, we use MongoDB, which is classified as a NoSQL database. In addition, MongoDB is an open source platform, document-oriented database that provides high performance, high availability, and automatic scaling. Unlike existing relational database, there are no schema or tables with MongoDB, and its most important goal is that of data accessibility and data processing performance. In the Age of Big Data, the visualization of Big Data is more attractive to the Big Data community because it helps analysts to examine such data easily and clearly. Therefore, TITS uses the d3.js library as a visualization tool. This library is designed for the purpose of creating Data Driven Documents that bind document object model (DOM) and any data; the interaction between data is easy and useful for managing real-time data stream with smooth animation. In addition, TITS uses a bootstrap made of pre-configured plug-in style sheets and JavaScript libraries to build a web system. The TITS Graphical User Interface (GUI) is designed using these libraries, and it is capable of detecting issues on Twitter in an easy and intuitive manner. The proposed work demonstrates the superiority of our issue detection techniques by matching detected issues with corresponding online news articles. The contributions of the present study are threefold. First, we suggest an alternative approach to real-time big data analysis, which has become an extremely important issue. Second, we apply a topic modeling technique that is used in various research areas, including Library and Information Science (LIS). Based on this, we can confirm the utility of storytelling and time series analysis. Third, we develop a web-based system, and make the system available for the real-time discovery of topics. The present study conducted experiments with nearly 150 million tweets in Korea during March 2013.

Infantile hypertrophic pyloric stenosis(IHPS), which occurs three of 1,000 live births, is a major cause of nonbilious vomiting of early infancy but its etiology and pathogenesis are still obscure. The operation of pyloromyotomy as described by Ramstedt in 1912 remains the standard of care for the treatment of IHPS. From January 1993 to October 1996, 35 infants with IHPS were surgically treated and the following results were obtained. 1. Thirty-five patients comprised 32 males and 3 females, and the ratio of male to female was 10.7:1. 2. The most prevalent age group was between 2 weeks and 8 weeks. 3. Of 35 infants, first born babies were 23 cases(65.7%). 4. Breast feeding was in 23 cases(65.7%). 5. The body weight percentile at admission was lower than 50 percentile in all 35 cases. 6. Onset of symptoms was predominantly between 1week and 2 weeks in 11 cases(31.4%). 7. All had a history of nonbilious vomting, generally projectile in nature. 8. In the measured serum electrolytes, hypokalemia was noted in 9 cases(25.7%), hypochloremia was observed in 14 cases(40.0%). 9. In the preoperative ultrasonography, the average muscle thickness, diameter, and length of the pylorus were 6.2mm, 12.1mm, and 17.9mm, respectively. 10. Among 35 cases, significant sonographic criteria of IHPS, muscle thickness of 5mm or more, were noted in 26 cases(83.9%). 11. A total of seven associated anomalies were noted in six patients. 12. All 35 cases were treated with Fredet-Ramstedt pyloromyotomy. 13. There were postoperative complications of wound infection in 2 cases. Intermittent nonprojectile vomiting was presented in 8 cases(22.9%) after operation, but one of them was relieved in 13 days and the rest were relieved within one week by adjustment of oral intake.

Infantile hypertrophic pyloric stensosis(IHPS) occurs in three of 1000 live births, and is a major cause of nonbilious vomiting of early infancy. It's etiology and pathogenesis however are still obscure. The operation of pyloromyotomy described by Ramstedt in 1912 remains the standard treatment. From January 1990 to July 1997, 64 infants with IHPS were treated at the Department of Pediatric Sursery, Yeungnam University Hospital. The ratio of male to female was 7:1, and the most prevalent age ranged from 2 weeks to 8 weeks(81.2 %) of age. Fifty-seven infants were first born (57.8 percent). The body weight of all patients at admission was below the 50 percentile. Age of onset of symptoms was between 2 and 4weeks of age in 23 cases(35.9 %). All infants had a history of nonbilious vomting, generally projectile in nature. Hypokalemia was noted in 14 cases(21.9 %) and hypochloremia in 26 cases(40.6 %). In the preoperative ultrasonography, the average muscle thickness, diameter, and length of the pylorus were 6.3 mm, 12.3 mm, and 17.8 mm. A total of 13 associated anomalies were noted in 12 patients. All cases were treated with Fredet-Ramstedt pyloromyotomy. Postoperative wound infection occured in 3 cases. Thirteen cases(20.3 %) presented intermittent nonprojectile vomiting after operation. With control of oral intake vomiting subsided within one week in 63 patients, and in thirteen days in another.

This study is to reveal the overall level of loneliness, depression and social supports of the elderly in rural area of Korea. The interview survey was performed in February 2001 with structured questionnaires to 486 respondents of 65 years or more of age who lived in Muan-gun area. The questionnaire was the revised translation of Japanese Elderly Study Which was composed of general characteristics, Japanese Loneliness Scale, abridged General Depression Scale(GDS) and Duke University social support Inventory. The following analyses adopted the analysis of covariate, t-test, and Chi- squire were used for some of the cross- sectional analyses. Average age of 486 respondents was 73.9 years old. 58.0% of the respondents noticed their partner or son as the primary consultant for the stressful situation. 56.2% of the respondents experienced the loss of their marital partner, health and/or friends. Average score of loneliness, GDS and social supports of the respondents that was each $35.54{\pm}8.38$, $7.23{\pm}2.21$ and $26.01{\pm}.90$. The overall level of depression seemed to be low as the 'pleasure to be alive' and 'happiness' scored high while the 'state of anger' and 'ominous presentiment' scored low. The level of loneliness and depression was positively correlated while the relationships were negative between loneliness and support and between depression and social support. These results suggested that social and health promotional programmes be necessary for the elderly of rural area. Further research would be required to specify the necessities.

This study concern with the pattern of Pusan Station shopping district within Pusan City, Korea, one of the special functioned shopping district within Pusan City. This paper will serve as a part of series studies which attempt to clarify the internal structure of Pusan as a whole. Part(II) of this study deals with the functions including living related, restaurants and others. The pattern of floors, size of shops, street corners and widths of streets were also analysed. The results are as follows: 1. In terms of numbers of firms in living related function, Pusan Station shopping district is the $7{\sim}8th$ ranked central place among nine the highest centers within Pusan City. Pusan Station shopping district has not much promoted vertical spatial differentiation comparatively, and also it's intensity of land use is the lower among nine the highest centers. It is presented that intimate relationship between intensity of vertical land use and classes of central places within the city. The ratio of inns and hotels in Pusan Station shopping district is third ranked in Pusan City. And the size of inns and hotels in this area is the most largest among the nine highest ranked central places within Pusan City. These presented that the traditional characteristics of station area as a special functioned shopping district. Inns and hotels mainly located along the narrower and back street. And it forms agglomerated areas or 'an alley of inns' at the inner parts of blocks, some like a 'hidden flower'. In Korea, 'alley' means that an area of specialization gains the prestige, traditionally. 2. Restaurants mainly locate along the narrower and back streets. And agglomerated areas of restaurants coincide with the agglomerated area of drinking places. It shows that these two kinds of functions need the same locational conditions. The ratio of Chinese restaurants is the highest in the Pusan Station shopping district. It's due to the agglomerated area these kinds of restaurants at the 'China town'. 3. Pusan Station shopping district has been formed along the streets within the residential areas. It's means that this shopping district now at the initial or middle growth era in development stage of shopping areas. 4. In general, wholesales and light manufacturing are located at peripheries within shopping district. But in Pusan Station shopping district, it dose not appear these spatial pattern. It shows that this area is lower ranked central place and not much progressed in spatial differentiation. 5. Particular firms which customers and workers have stayed more longer period of time are located at the far from the first floor. This vertical spatial differentiation is similar to the horizontal sequences. 6. Firms which have more ability of rental payment are located at street comers such as banks and pharmacies. In Pusan Station shopping district commercial facilities could not invade into the second third floors at narrower streets and first floor of back streets, still now.
