This study is a descriptive study designed to identify the relationships among self-leadership, positive psychological capital, and learning flow, and the mediation effect of positive psychological capital between self-leadership and learning flow. The participants for this study were 218 nursing students following a four-year curriculum in J city and the data was collected from April 1st to April 15th, 2016, and analyzed using descriptive statistics, the t-test, one way ANOVA, Pearson's correlation and multiple regression with the SPSS 22.0 Program. There were significant correlations among self-leadership, positive psychological capital, and learning flow. In the multiple regression analysis, the main factor affecting learning flow was self-leadership, which explained 44.1% of the variance in learning flow. Moreover, of 4 the components of positive psychological capital, self-efficacy and hope had a partial mediating effect between self-leadership and learning flow. Self-leadership, positive psychological capital, and learning flow relationship were positive relevant. To enhance the learning flow ability of the nursing students, it is necessary to develop a training program to increase their self-leadership and positive psychological capital.

The purpose of this study was to investigate psychological separation, depression and antidepressive coping behaviors and to examine the relationship between psychological separation, and depression in Korean university students. The subjects were 131 students who were in 4 university in Chungcheong-do, Korea. The data were collected through self reported structured questionnaire using the psychological separation index, beck depression inventory and antidepressive coping behaviors instrument. The level of depression was classified into; not depressed, 54.2%; mildly depressed, 22.9%; moderately depressed, 16.8%; severely depressed, 6.1%. Among antidepressive coping behaviors, cognitive activity-oriented behaviors was the one with highest percentage(30.8%). Depression was negatively related to functional independence, attitudinal independence, emotional independence from father and conflictual independence from mother. And depression was positively related to conflictual independence from father. These results suggest that it is necessary to develop nursing intervention to strengthen psychological separation form parents and to be able to help desirable antidepressive coping behaviors for the psychological health of university students.

Fungi which were capable of producing gluconic acid were isolated from soil and tree leave samples, which had been collected in Seoul ana its vicinity. Among the 19 strains isolated, a strain named arbitrarily KUF-O4 was selected as a test strain chiefty because of its efficiency in gluconic acid production. The strain was identified as an Aspergillus sp. through its morphological properties. Optimum conditions for the gluconic acid production of KUF-O4 were investigated. The results obtained are as follows. 1. An incubation period of at least 30 hours was required for a good yield of gluconic acid. 2. A medium containing 10％ glucose needed at least 3 ％ CaCo$_3$to maintain the optimum pH for the production of gluconic acid during fermentation. 3. As a carbon source, glucose was the most effective one among the carbon sources tested. 4. As a nitrogen source, an ammonium salt was more effective than any other form of nitrogen compounds. 5. As mineral source, a small amount of both KH$_2$PO$_4$and MgSO$_4$was found to be necessary to increase the efficiency of the gluconic acid production.

It is well known that the exercising and stimulating of fingers have an important bearing on the brain. We take note of the fact and develope a game device for improving one's health and brain ability in respect of the education and training. Especially, we develope the device focused on the balanced exercising of five finger for improving brain function. The game device is possible to used in two-ways, namely online and off-line mode. In online mode, the device is connected with other visual devices such as smart phone and smart TV and communicated with Bluetooth and it is used as a MMI(multi-modal interface) device. Whereas, in off-line mode the game device works independently and it makes possible to enjoy auditorial and tactual games without video images for promotion of brain activity and emotional cultivation. For certification of the device, we implement two games(a fishing game for off-line mode and a shooting game for online mode) for people of all age, especially good for the elderly. It is usable as a game device to offering the elderly a great help for preventing impairment of the cognitive functions.

The purpose of this study is to provide basic data for the oral health and obesity management of adults by grasping the relationship between obesity and oral health. Among the patients who visited the dental clinic, 229 patients who agreed to fill out questionnaires were analyzed by self - filling questionnaire. Body mass index and waist circumference were used for the study of obesity. Body mass index and poor periodontal health status were significantly higher(33.3%) and abdominal obesity and poor periodontal health status were 10.9%.Abdominal obesity was significantly higher(28.6%) in the group with less than 20 teeth. Body mass index and abdominal obesity were higher in body pain, psychological discomfort, physical abilities, psychological abilities, social disadvantage, and oral health than in normal subjects. As a result of correlation analysis with obesity index, it was found that the more period of obesity, the more periodontal disease and mucosal state related symptoms appeared(p<0.05). Therefore, in order to solve health problems such as obesity, it is necessary to recognize the importance of oral health and to make efforts to induce positive oral health behavior.

In this paper, we use the ECMA-392 standard, the first cognitive radio networks to meet the demand for IT services in the ship. And, we investigate about the conflicts of devices that support multi-hop network based on the ECMA-392. Therefore, we propose the resolution scheme of CRP reservation conflicts to solve this. The current CRP reservation approaches does not solve the CRP reservation conflicts of ECMA-392 between devices that move at a distance of three hops. Therefore, it is not possible to guarantee the QoS of real time services such as multimedia streaming. So, we provide a new CRP reservation scheme to avoid conflict through a new 2-hop CRP Availability IE and the change of CRP Control field. From the simulation results, we know that the proposed method of 3 hops CRP reservation conflicts resolution improves the throughput of device.

The purpose of this study is to examine how Korean dance affects middle-aged women by acting as a cultural mediator. A qualitative approach was taken in order to best achieve the purpose of this study. The data used in this study were collected from Feb 10th to April 1st, 2016, using in-depth interviews. The results are as follows; firstly, on an emotional level, the middle-aged women participating in Korean dance as a cultural mediator, feel a sense of self-achievement and social belonging, as well as experiencing an improvement in their psychological stability by resolving their depression. Those who had lost their sense of autonomy and productivity were able to recover some of their self-esteem through this activity. Secondly, in terms of their activity, the Korean dance enabled the ladies to exercise their poorly used muscles by strengthening their gross and fine motor skills through the movements associated with the Korean traditional music. This allowed them to ease their chronic physical pain and it can be considered that their overall exercise function was increased by expanding their exercise radius. Third, in the cognitive area, it was possible for them to revive their happy memories by listening to the music which was loved by their preceding generations. This is because the melody of familiar Korean music provides them with the chance to remember their former days. Lastly, in the social area, the Korean dance allowed the middle-aged women to accept themselves through music and movement, as well as playing the role of a mediator which enabled them to overcome their isolation and the conflicts they face in their social relations. In addition, they achieved self-realization by reconnecting with the regional community through the Korean dance performances, which they learned as social community members.

This study was conducted to identify the factors affecting the quality of life of cancer patients based on demographic characteristics, health status, and mental health using the results of the 6th National Health and Nutrition Survey. The research tool used the demographic characteristics, health status, mental health, and quality of life of the KNHANES VI-2. Data analysis was conducted using SAS 9.3 version. There were significant differences in the quality of life in the study results by age, gender, economic activity, individual income quartile, subjective health status, mental health status, activity limitation, stress perception, and experience of depression symptoms. Factors influencing the quality of life of cancer patients included age, sex, income quintiles(individual), subjective health status, activity limitation, and experience of depression symptoms, which together explained 39.1% of the quality of life. To improve the quality of life of cancer patients, comprehensive management is required from diagnosis to treatment to return to society. It is also necessary to develop and apply long-term programs including multidimensional approaches and improvement of quality of life, early screening of cancer and cancer prevention education, management of depression symptoms, and social support.

This study carries out to evaluate the value of introducing the road guard system that merges the function of a fence that induces wild animals and a grass inhibitor to an existing guard rail that acts as road safety facilities. For this purpose, we surveyed that road user's willingness-to-pay and recognition characteristics for road safety facilities using contingent valuation Method. By establishing a willingness-to-pay assumption model, the average willingness-to-pay was 5,018 won, which was higher than the average proposed amount of 3,883 won and shows that the road guard system is an appropriate alternative facility to increase road safety and reduce road kills. Therefore, it would be prudent to review the introduction of the road guard system to newly constructed roads or current roads in operation as a way of reducing road kills. In the future, the road guard system must be tested in areas that are highly susceptible to road kills after consulting with the relevant highway managing authorities to conduct a comparison study on the before and after installation effect of the road guard system to investigate its operation and the current status of road kills to clearly identify its effectiveness.
