Recently, the global financial crisis and the increasing number of unsold houses in Korea are construction companies to assess their efficiency. The most important factor in analyzing the efficiency of a company is the input-output variable. However, systematic stud the core input-output variables, which have a great influence on the efficiency analysis. Thus, to the core input-output variables for efficiency analysis of construction companies, this study propose a model that includes all combinations of input-output variables and to find the core input-output variables using the Data Envelopment Analysis(DEA) model and Principal Component Analysis(PCA). Existing research and theories were studied variables and 21 models were established to measure efficiency. were obtained that the core input and output variable in 2006 the number of employees and sales. For 2008, the core input variable was capital stock and the core output variable was quarterly net profit. For 2010, the core input variable was fixed asset and the core output variable was sales. Through obtaining the variables that greatly affect the efficiency of construction companies, it is considered that individual construction companies will be able to prepare a priority strategy to enhance efficiency.

This paper aims at analyzing the practice of job rotation in the Korean government and putting forward policy suggestions. The Korean government is often accused of low capacity and weak competitiveness, which mainly result from the low expertise of public officials. Considering the high quality of human resources flowing into the public sector in Korea, solutions should be found from the structure of the system. This paper regards frequent position changes due to excessive job rotation as a key factor undermining the accumulation of expertise and conducts in-depth analyses. The current practice of frequent rotation shows that the average tenure period of government officials at director level and above is only about one year, far shorter than those in major developed countries, which causes many problems such as low efficiency, lack of accountability and policy consistency, and low opportunity for accumulating expertise. Simple models are set up to analyze job rotation and other alternative personnel management systems. Analyses find that it would be desirable to have each individual experience various positions during the initial rotation period to find his/her own aptitude, and then accumulate expertise by settling in at a certain specialized field for a prolonged period of time based on the revealed aptitude in mid and high positions. This turns out to be in line with the structure of the Career Development Program which is being introduced. The model-based analysis of this paper distinguishes this study from preceding ones conducted in the traditional framework of personnel management study. Practical measures to mitigate the problems of frequent job rotation include rotating within the area of specialty, narrowing the scope of transfer, and reinforcing the minimum tenure period. However, since the current frequent rotation is fundamentally attributable to the rank system based on seniority, the present civil service classification system needs to be converted into a position classification system in the long run.

Through this literal study, we have endeavored to provide korea's unique nursing intervention methods based upon Lee Je-Ma's Sasang Constitutional Theory which is a unique korean medical science. The Sasang Constitution Theory lay great emphasis upon health caring medicine to promote health according to self Constitution at normal times, preventive medicine to manage byself body and mind in everyday life, and eventually, ethical medicine to love benevolence and kindness but to dislike jealousy.A variety of methods has been introduced to diagnose a person's Constitution. And yet, appearance, mind and pathological signs are three major criteria. In appearance, comprehensive features such as figure (the shape of the human body), countenance, behavior, mood, and posture are observed. In mind, nature (character), talent, steadiness, personality, and greed are investigated. In pathological signs, physiological conditions when healthy and peculiar symptoms when being ill are diagnosed. By these three criteria, each Constitution is categorised into Taiyang Person, Soyang Person, Taieum Person or Soeum Person. Different healthcaring methods exist for each Constitution such as mind and body healthcaring, diet healthcaring, knowledge and behaviour leathering, age group healthcaring, regional healthcaring, social life hralthcaring, everyday life healthcaring, and materia medication healthcaring. An independent and unique healthcaring method for each person according to self Constitution could be an important nursing intervention strategy, and can product a new nursing theory. To enjoy longevity by inducing positive caring methods, I believe that individual nursing may be the most desirable nursing approach. Lee Je-Ma's Sasang Constitution caring method is not only a general nursing theory but also expected to be an important landmark/milestone/factor in Korean nursing, preventive nursing, developing new nursing intervention methods and forming new nursing theories. Therefore, it is required to conduct thorough, practical and theoretical researches in the field of nursing.

This paper focused on providing the groundwork for the development of proper nursing interventions to enhance the quality of life for the elderly by identifying the factors that may affect their health beliefs and behaviors. A survey was conducted on a group of people aged between 60 and 86 years residing in S and K cities from January to March of 2003, who agreed to participate in the research. Data was collected using instruments measuring health beliefs and health behaviors, and was analyzed by using SPSS. The results of this study are as follow. 1) Those in the group were aged between60 and 86 years, and the average age was 66.94 years old. Most of them were living together with their spouses. From the survey, 83.5% replied "above average" on the question regarding their current health condition, whereas, 46.0% mentioned that they had some sort of diseases. 2) Overall average score of the health belief was 516.05, with a mean $3.71{\pm}4.07$. This indicates that the studied group held a high level of health belief, which affects their attitude and intention to lead a healthy life by placing the present life under control in harmony with nature. 3) Overall average score of the health behaviors was 392.24 with a mean $2.82{\pm}.52$. For health purposes, the behaviors that the elderly people were taking were mostly static ones requiring a low level of activity. The analysis showed that they generally were involved in self-trained, individualized health care. Thus, the elderly place a higher priority on regular dietary behaviors than on physical activity. 4) The correlation between health belief, a cognitive aspect on health, and health behaviors, a behavioral aspect showed a very high linear relationship (r=.520, p<.000). Consequently, it is found that those who have higher cognitive health belief are involved in higher level of behavioral health practice. These findings concluded that the Korean elderly have good health beliefs, well controlling their minds and being harmonious with nature. Health behaviors that they are engaged in are mostly static, requiring low level activity, while they place higher priority on regular dietary habits and conducting self-trained individualized health care. Important factor affecting their health beliefs and health behaviors was found to be their health practice. Since higher health belief is highly related with good health behaviors, development of health activity programs is in need as a means for an efficient health improvement, where motivating environment may be established to enhance the health belief of the elderly and to satisfy individual values.

Wished to examine closely effect that SoPungDoJeokTang-KaMi (SPDJTK) medicines used to atopy dermatitis disease patient get in atopy eruption control experimentally. SPDJTK medicines controlled $CD4^+/IFN-\gamma$, and $CD4^+/CD25^+/foxp3^+$ revelation that an experiment that motive allergy immune reponse because an in vitro experiment stimulates T cells of a NC/Nga mouse same time by anti-CD40/rmIL-4, and interleukin-$1{\beta}$, IL-6, TNF-$\alpha$, and TGF-$\beta$ mRNA outturn that bear in T and B cells decreased remarkably by SPDJTK medicines. Intracellular staining of splenocytes anti-CD40/rmIL-4 plus rmIL-4 stimulated as described in a, assessed after 24 h, SPDJTK exerts a mainly immunosuppressive effect that acts at least partially through suppression of the transcription factor GATA3 expression in $CD4^+$ T cells. Atopic dermatitis (AD) usually develops in patients with an individual or family history of allergic diseases, and is characterized by chronic relapsing inflammation seen specially in childhood, association with IgE hyperproduction and precipitation by environmental factors. However, the exact etiology of AD has been unclear. To further explore the pathogenesis and treatment of AD, a suitable animal model is required. We found that skin lesions, which were clinically and histologically very similar to human AD, mite antigen-induced dermatitis on the face, neck, ears and dorsal skin of inbred NC/Nga mice. Result that Th1 cell and Th2 cell observe to be shifted by cytokine expression with $CD4^+/CD25^+/foxp3^+$ Treg cells induction by SPDJTK medicines could know that SPDJTK medicines can use usefully in allergy autoimmnune diease.

Purpose - This study is to propose a creative idea for constant business growth and development by examining characteristics of business outcomes by phase, which are "growth" and "erosion and stagnation," respectively. Research design, data, methodology - It is necessary to identify an occurrence of crisis and its diffusion with a dynamic model in order to identify a success and failure of businesses in an organic way, not on a binary structure. The static perspective is to understand a crisis as a simply one-time event or as a linear causation. Thus, it has a limited understanding of the overall situation and has limits to investigating a foundational cause and developing long-term countermeasures. On the contrary, the dynamic perspective is to understand the crisis as circulation process of the overall system. Thus, it divides elements of the crisis as external and internal ones to understand it as the causal relationship of each element. Results - During the growth period of Burger King, the company promoted its brand very successfully with aggressive and creative marketing activities. However, due to the founder's disposal of management rights and the following changes in the management, the company had no choice but to lose focus on its business philosophy and brand management, and eventually it had to face the big crisis (resonance) which was delisting from the stock market because of the external threat; well-being trend. However, Burger King resumed lifting on the stock exchange by making great efforts to clearly identify the current issues and seek solutions. Under the spirit of "perseverance" and its slogan "Have it your way" the company is now going head to head with McDonald's in the North American region and emerging countries. Conclusions - Then, what is the most crucial factor in the success and failure of businesses? Answers may vary, however, as learned from the case study of Burger King, corporations should inspect the present and focus on developing a long-term strategy for the future and actively fulfill the actions. McDonald's may not be able to innovate by itself in the future as it may become routinized to the growth. There will be chances of winning if we change conditions of individuals or organizations to an organic system in terms of being creative. There is a hopeful message here that an individual or small business may have more advantages in the era of the idea and innovation.

Recent years have seen an explosion of interest in interactive agents motivating human learners to engage in edutainment systems which are designed to be entertaining and educational at the same time. Especially, work on socio-emotional processes has focus on understanding of human's social behavior in training and entertainment a applications. In contrast with work on social emotion, where research groups have developed detailed models of emotional processes, models of personality have emphasized shallow surface behavior. Here, we build on computational appraisal models of emotion to better characterize dispositional differences in how people come to understand social situations. Known as explanatory style, this dispositional factor plays a key role in social interactions and certain socio-emotional disorders, such as depression. Building on appraisal and attribution theories, we model key conceptual variables underlying the explanatory style, and enable agents to exhibit different explanatory tendencies with respect to their personalities. Furthermore, we developed an interactive AR agent based on our framework and applied it into an interactive teaming system that allows participants to explore individual differences in the explanation of social events, with the goal of encouraging the development of perspective laking and emotion-regulatory skills.

The purpose of this study was to investigate the factors affecting the actual condition and effectiveness of orthodontic treatment among some dental hygienists and students. This study was carried out from September to December, 2016 to describe the purpose of the study and the method of writing the questionnaire for some dental hygienists and students. The final 430 sections were analyzed and analyzed using PASW Statistics 18.0. First, the duration of orthodontic treatment was 34.4% for college students, 36.9% for orthodontic treatment for less than 2 ~ 3 years, and 62.3% for internal motivation. The factors affecting the orthodontic treatment effect were the patient's cooperativeness and the hospital's scale was the lowest. The higher the grade level, the more the clinical experience and dental part-time experience were, the higher the correlation between dental specialty and dental hygienist's medical service, education and counseling was .521(P<0.001). The higher the level of cooperation, the higher the grade level, the more dental treatment and orthodontic treatment experience, the lower the level of family co - operation. Therefore, it is important to emphasize the importance of cooperation of orthodontic patients and to develop a strategic program for each individual patient.

Objectives: Korean elderly people are known to consume diets high in carbohydrates low in vegetables compared to other age groups. This study evaluated the chronic disease risks and nutritional status in this group based on the percentage of energy from carbohydrates and the frequency of vegetable intake. Methods: Using the 2007~2009 Korean National Health Nutrition Examination Survey data, except those who were undergoing treatment for chronic disease, final 1,487 subjects aged 65 and older were divided into 4 groups: moderate carbohydrate energy ratio of 55~70% and low frequency of vegetable intake defined as less than 5 times per day (MCLV), moderate carbohydrate ratio and high frequency of vegetable intake more than 5 times (MCHV), high carbohydrate energy ratio above 70% and low frequency of vegetable intake less than 5 times (HCLV), and high carbohydrate ratio and high frequency of vegetable intake more than 5 times (HCHV). All data were analyzed after the application of weighted value, using a general linear model or logistic regression. Results: More than half of Korean elderly consumed diets with HCLV, and this group showed poor nutritional status and lower frequency of intake of most food items, but with no risk of chronic disease such as diabetes, obesity, hypertension, cardiovascular disease or anemia probably due to low intake of energy. On the contrary, MCHV group with a high percentage of energy from fat and protein showed the highest intake of energy and most nutrients, the highest frequency of intake of most of food items and a tendency of high risk of abdominal obesity, being followed by the MCLV group. Meanwhile, HCHV group showed a tendency of high risk of hypertension, followed by HCLV group with low frequency of intake of vegetables compared with the two moderate carbohydrate groups. Conclusions: The results suggested that the percentage of energy from carbohydrate and the frequency of vegetable intake affected the nutritional status, but not significantly affected the risk of chronic disease in Korean elderly. Further studies using more detailed category of % energy from carbohydrates and of type and amount of vegetables with consideration of individual energy intake level, excessive or deficient, are needed to confirm the results.
