Background : It is very common in Korea to take care of non-acute patients in an acute setting, due to the lack of long-term facilities. Long term hospitalization increase medical expenses and decreases the bed utilization, which can affect the urgent and emergent admissions, and eventually jeopardize the hospital financially. In this study, strategies for effective transfers to the lower levels of care, and to decrease the length of stay were presented by surveying and analyzing the patient's knowledge of the transfer needs, and the willingness to transfer those whose hospital length of stay was more than 30days. Method : The survey is subject to a group of 251 patients who have been hospitalized over 30 days in a general hospital in Seoul. Excluding those that were in the Intensive Care Unit and psychiatric ward, 214 in-patients were used as participants. They were surveyed from April 9, 2002 to April 17, 2002. One hundred and thirty seven out of 214 were responded which made the response rate 64%. Data were analyzed by SAS and SPSS. Result : Multi-variable Logistic Regression Analysis showed a significant effect in medical expenses, knowledge of referral system and the information of the receiving hospital. The financial burden in medical expenses made the patient 10.7 times more willing to be transferred, knowledge of the referral system made them 5 times more willing to be transferred, and the information of receiving hospital makes 6.5 times more willing to be transferred. Reasons for willing to be transferred to a lower level of care were the phase of physical therapy, the distance from home, the attending physician's advice and being unable to be treated as an out patient. Reasons for refusing to be transferred were the following. The attending physician's competency, not being ready to be discharged, not trusting the receiving hospital's competency due to the lack of information, or never hearing about the referring system by the attending physician. Conclusion : Based on this, strategies for the effective transfer to the lower levels of care were suggested. It is desirable for the attending physician to be actively involved by making an effort to explain the transfer need, and referring to the Healthcare Coordinating Center, which can help the patient make the right decision. Nationwide networking for the referral system is the another key factor that may need to be suggested as an alternative to decrease the medical expenses. Collaborating with the Home Health Agency for the early discharge planning and the Social Service Department for financial aid are also needed. It is recommended that the hospital should expedite the transfer process by prioritizing the cost and the information as medical expenses, knowledge of referring system and the information of the receiving hospital, are the most important factors to the willingness to transfer to a lower level of care.

Purpose - This study aims to (a) analyze local citizens' perception of a local company, the Gwangyang Steel and Iron Company (GSIC); (b) compare the perception toward the local company with that of national citizens' perceptions towards many other unspecified companies, which were surveyed biannually by The Korea Chamber of Commerce and Industry (KCCI); and (c) analyze how such companies evaluate perceptions towards them, in relation to citizens' socioeconomic position, such as their education status. Research design, data, methodology - The data were collected using a questionnaire, which was given to a sample of local citizens in cities. To test the hypotheses, factor analyses, a t-test, and an ANOVA were conducted. The total number of respondents was 1798. The data gathered from the respondents of the sample were analyzed using SPSS Win 19.0 software. Perception towards the company was evaluated on the corporate favorite index (CFI). The CFI index shows how positive citizens feel towards a company. It is calculated using five leading factors, consisting of the following: contribution to the economy, productivity, international competitiveness, social contribution, and ethical management. The higher the level of positive feelings exhibited, the closer the index will come to 100. Results - As a result of the analysis, the CFI index towards the GSIC stood at 67.3. The CFI index towards the company is 16.5 points higher than that of the index towards the many other unspecified companies, which were surveyed by the bi-annual KCCI study in the first half of 2011. The other five indexes stood as follows: contribution to the economy, productivity, social contribution, and ethical management was 69.2, 71.2, 64.6, and 58.6, respectively. These indexes are 18.3, 4.6, 27.6, and 35.6, respectively, higher than those found by the KCCI study. However, international competitiveness is 73.0 (9.8 points lower than that of the KCCI study). This survey thus shows that the CFI of the local citizens towards the global company GSIC is very high when compared with the CFI index towards the many other unspecified companies that was determined by the KCCI survey. Conclusions - This survey shows that local citizens have high expectations of economic activity, increasing working opportunities, and regional cooperation projects from the local company, GSIC. In addition, the CFI index towards GSIC evaluates results depending on the respondent's relationship with the company, and their educational status. Respondents, whose family or relatives were working as employees of GSIC, have relatively positive perceptions of GSIC, and respondents with a relatively higher educational status also share positive perceptions. Local citizens expect the profit-making of the company to operate in accordance with management activities, and at the same time, they expect that the wealth generated by the company will return to wider society.

The purposes of the study are to examine the relationship amongst adolescents' internet usage, fandom activities, sense of community and their mental health in the digital era and to probe into the effect of internet usage, fandom activities, sense of community on adolescents' mental health. The results are as follows: First, there were statistically significant correlations among those four factors. Secondly, it shows that the effect of internet usage, fandom activities and sense of community on the adolescents' mental health have a difference by gender. In the case of female adolescents, there is no effect of internet usage on their mental health. But, the study reveals that adolescents' internet usage and fandom activities which now are accepted as a part of their culture, could be combined with the sense of community and could have an effect on the adolescents' mental health. Furthermore, the study casts a light on the possibility to build a strong point on adolescents' activities, education, counseling and policy making for the purpose to enhance adolescents' mental health in the future.

In buildings on the street, indiscriminate redevelopment are being made by overlooking the relationship with surrounding landscape to create their own unique meaning, due to industrialization progressed rapidly with human needs of longing for something constantly. Selection and methods of two plans, conservation and utilization should be required, considering heritage values on industrial buildings which are being lost and aged in this redevelopment higher. The attempt for the use of modern industrial heritage becomes a hot topic, and several experimental challenges are being made. However, there are rather many cases of causing industrial buildings' depreciation and one-size-fits-all reproduction performance as it applies other examples as standards by recognizing the reproduction of modern industrial heritage as one trend, not focusing on the trend of the times or paradigm, what the times want. To minimize these problems, we focus on how to utilize industrial buildings beyond the importance of industrial buildings' reproduction, considering the quality of local residents' life as well as the expected effect obtainable due to security of local identity and reproduction of buildings, focusing on the concept of community design that offers and forms a way of community life as the design of shares based on unspecified individuals' common life. Community design's core can be called to have diversity rather than undifferentiated unity by pursuing whole unification, since local residents become those who plan design and all people participate in it. In addition, community design achieves integration with other fields as an enlarged design area without limiting in an environmental area, by making indigenously natural characteristics combined with cultural factors in one context so that people may understand the flow of the place. The importance of effects acquired from modern industrial heritage's reproduction has well-known, and the attempt for utilizing aged heritage as a new value and a function has constantly been made. Now, it's time to focus on how long it lasts through this method, rather than modern industrial heritage's reproduction itself. There can be a significance in this study in proposing methodological solutions on modern industrial heritage's reproduction, not to cause depreciation of industrial buildings by recognizing contemporary trends and uniform regeneration performance, multifaceted research is needed for creative, effective development on modern industrial heritage which will occur constantly.

This study was conducted to investigate the bark production from a top branch(Woojuk) of lacquer tree(Rhus verniciflua) that collected Rhus lacquer in summer, analyzing a relationship between several factors - diameter, tree weight, weight of Woojuk and bark. The weight of Woojuk averaged was made up $48\%$ of the tree on average. As the weight of the tree increased, however, the Woojuk showed the rising trend. It was turned out that the tree size for making 1kg of dry bark must be at least DBB 8cm. The result on Woojuk's bark was that $43.3\%$ of total trees produced a green bark of 1.1kg to 1.5kg, and most of them put out 1.5kg and less. Also the rate of trees to make 0.6kg to 1.0kg of dry bark was highest in $50.8\%$, but its production in most trees was 1.0kg and below. As the moisture content of a green bark averaged $39\%$, it is estimated that the production of 1kg in dry bark requires at least 6kg of top branch in lacquer tree.

The purpose of this study is to identify the effects of involvement in temple food on overall satisfaction, recommendation, and revisit intention. From June 15 to August 30, 2014, for those who have participated in temple stay at four temples in South Korea, the self-administered survey was conducted. Of a total of 400 questionnaires, 289 were employed for the analyses, which accounted for 72% of response rate. Results shows that the involvement in temple food positively influenced experience driven by motivation in temple stay. Considering a particular research topic of temple stay, it implies that the involvement in temple food plays a key role in affecting emotional and social value relating to experience in temple stay. Entertaining, educational, aesthetic, deviated factors created by this experience will contribute to making special memories and feeling great enjoyment. In addition, emotional and social value by temple food have a positive effect on recommendation and revisit intention through experience satisfaction. Furthermore, experiential factor was significant to overall satisfaction, revisit and recommendation intention. Social and emotional value according to involvement in temple food, in terms of conclusions in this study, influenced a reduction of stress and improvement of enjoyment. These values relating to involvement in temple food, therefore, are assumed to be the causal relationship with experiential factor and satisfaction in temple stay and subsequently will be regarded as determinants in defining temple food as a heathy dish.

In this paper, we propose health risk management using feature extraction and cluster analysis considering time flow. The proposed method proceeds in three steps. The first is the pre-processing and feature extraction step. It collects user's lifelog using a wearable device, removes incomplete data, errors, noise, and contradictory data, and processes missing values. Then, for feature extraction, important variables are selected through principal component analysis, and data similar to the relationship between the data are classified through correlation coefficient and covariance. In order to analyze the features extracted from the lifelog, dynamic clustering is performed through the K-means algorithm in consideration of the passage of time. The new data is clustered through the similarity distance measurement method based on the increment of the sum of squared errors. Next is to extract information about the cluster by considering the passage of time. Therefore, using the health decision-making system through feature clusters, risks able to managed through factors such as physical characteristics, lifestyle habits, disease status, health care event occurrence risk, and predictability. The performance evaluation compares the proposed method using Precision, Recall, and F-measure with the fuzzy and kernel-based clustering. As a result of the evaluation, the proposed method is excellently evaluated. Therefore, through the proposed method, it is possible to accurately predict and appropriately manage the user's potential health risk by using the similarity with the patient.

The specific muscular structure of the tongue greatly affects margin shrinkage and tumor invasion, making the optimal surgical margin controversial. This study investigated surgical margin correlated prognosis of TSCC (tongue squamous cell carcinoma) according to margin location and its value, and the histopathologic factors which are suggestive of tumor invasion. And we would like to propose defining of the surgical margin for TSCC via prognosis according to location and margin values. We reviewed 45 patients diagnosed with TSCC who visited Seoul National University Dental Hospital (SNUDH) (Seoul, Republic of Korea) from 2010 to 2019, who were managed by a single surgical team. Patient clinical and pathological data of patients were retrospectively reviewed, and in 36 out of 45 patients, the pathologic parameters including the worst pattern of invasion (WPOI) and tumor budding were investigated via diagnostic histopathology slide reading. When standardized with as 0.25 cm anterior margins, as 0.35 cm deep margin, there was no significant difference in disease specific survival (DSS) or loco-regional recurrence-free survival (LRFS). Additionally, there was a non-significant difference in DSS and LRFS at the nearest margin of 0.35 cm (P_DSS=0.276, P_LRFS=0.162). Aggressive WPOI and high tumor budding showed lower survival and recurrence-free survival, and there were significant differences in close margin and involved margin frequencies. In TSCC, the value and location of the surgical margin did not have a significant relationship with prognosis, but WPOI and tumor budding suggesting the pattern of muscle invasion affected survival and recurrence-free survival. WPOI and tumor budding should be considered when setting an optimal surgical margin.

Purpose: With the development of the Internet, consumers can quickly access the electronic word-of-mouth. Consumers seek to reduce uncertainty by referring to the opinions of other consumers about products and services when making purchase decisions. In the food service industry, evaluating a restaurant before an actual visitation is difficult. Therefore, electronic word-of-mouth is important to interact with the customer in restaurants. as it can be used as an exchange of information in which consumers participate and interact with other customers. This study was conducted to verify how online word-of-mouth characteristics (Consensus, Vividness, Neutrality) on attitudes and visit intention from the perspective of social exchange theory. And it was performed to verify the structural relationship between short-term visit intention, mid-term visit and long-term visit intention. Research design, data, and methodology: A survey was conducted on customers who have visited restaurants. Of a total of 312 responses, 306 responses were used, excluding insincere responses and missing values for factors analysis. SPSS 25.0 and AMOS 25.0 were used for statistical analysis, and hypothesis testing was conducted after verifying the validity and reliability of the questionnaire items. Result: The result of the analysis showed that, consensus and neutrality have a positive effect on attitude but not much on vividness. In addition, consensus, vividness, and neutrality have no effect on the short-term visit intention. Finally, the short-term visit intention has a positive effect on mid-term visit intention, and mid-term visit intention has a positive effect on long-term visit intention. Conclusions: Based on the results, this study suggested that it is necessary to have practical implications for marketing and monitoring restaurant reviews in consideration of the characteristics of electronic word-of-mouth. When managing electronic-word-of-mouth, it is necessary to manage the consensus and neutrality is essential to provide sufficient information about the restaurant. The focus should not only be on vividness, such as photos and videos. In addition, restaurants should also provide a good experience for first-time visitors as the short-term visit intention positively affects mid-term and long-term visit intention.
