Purpose: This study aimed to investigate the effects of a program for increasing self-care with activities of daily living among the elderly living at home. Methods: The study adopted a non-equivalent control group pretest-posttest design. The number of participants were 30 in the experimental group and 30 in the control group. Participants were persons aged 65 years and above in Busan. The experimental group was provided with for 16 different types of self-care behaviors by family nurses who made weekly home visits to these participants. Each visit lasted for more than 30 minutes, and the visits were conducted for 12 weeks. The research instrument used in this study was a scale developed by Shimanouchi et al. (2003) which assessed self-care behavior, activities of daily living, and depression. Results: The experimental group showed an increase in self-care behavior compared to the control group. Time and group variables were also found to have an interaction effect on the daily living activity level. The experimental group showed an increase in the activities of daily living compared to the control group. Depression scores dropped from 9.4 to 5.8 in the experimental group and from 8.6 to 7.0 in the control group. Conclusion: We found that the self-care behavior program improved the levels of independence and activities of daily living among the elderly living at home.

The objective of this study is to investigate actual conditions of terrestrial vegetation part in Environmental impact statement, and to prepare a proposal for the efficiency of Environmental Impact Assessment. 13 E.I.S.s made out during 1996.6-1997.5. have been chosen and analysed with respect to scope of survey, item of survey, method of survey, and result of survey. Actual conditioins of terrestrial vegetation part in E.I.S. are summarized as follows : 1. The mean number of total participants in drawing up E.I.S. is 26.0 persons, that of participants in terrestrial vegetation part is 2.3 persons. 2. In case of planar project, the mean of scope of survey is 16.1 times as large as area of project . In case of linear project, the scope of survey has been determined arbitrarily. 3. The most part of survey has been dependent on literature, and field survey has been practically neglected. 4. Results of survey mostly missed the point that E.I.A. pursues. And proposals are as follows : 1. Participants in terrestrial vegetation part in drawing up E.I.S should be increased. 2. It is necessary to subdivide scope of survey in view of difference between planar project and linear project. 3. As for item and method of survey, field survey should be specially reinforced. 4. Several sheets of map as results of survey should be included in E.I.S. The vegetation map, the D.G.N. map, and the planting map should be included and drawn by smaller scale as possible.

In 1992, the quality control program was introduced in Republic of Korea to improve the reliability of the work environment monitoring, which was introduced in the 1980s. The commission entrusted by the Ministry of Employment and Labor, the Occupational Safety and Health Research Institute has conducted the program for industrial hygiene laboratories including designated monitoring institutions and spontaneously participating agencies. The number of institutions that participated in the program has increased from 30 to 161. The initial conformance ratio in the participants was 43% (organic solvents) and 52% (metals). Thereafter, the conformance ratio increased rapidly and it has remained in a stable state at more than 89% since 1996. As subject materials, 13 kinds of organic solvents and 7 kinds of metals were used. To improve the capability of measurement and analysis of private institutions, educational courses were conducted annually. An assessment at the actual sites of participants was additionally introduced into the program in 2013. Thus, the program turned into a system that administrates the overall process of participants. For the future, the scope of target materials will be extended through additional items. Thus, the reliability of the results of the work environment monitoring is expected to increase accordingly.

At present the electric power industry in Korea is going through a major restructuring process. The restructuring is motivated by a desire to reduce electricity supply costs, to attract new in-vestment in modern generation, transmission and distribution facilities, and to stimulate innovation in the wholesale production and the retail supply of electricity. The experience to date shows that restructuring of electric power industry in the US, however, is marred with a number of problematic market performances including unreasonably high prices at wholesale. This paper investigates the important role of Power Exchange for stabilizing electric power industry in transition by offering various financial products. These financial products are used for risk hedging by the market participants. The paper focuses on the risk hedging by an individual supplier and derives an explicit decision rule that incorporates the attitude towards the risks. In addition to providing the financial products for risk hedging by market participants, the Power Exchange plays another very important role of financial safeguard system. Because of its unique characteristics, the Power Exchange is well suited for financial surveillance where it performs the early detection of unsound financial (and to a large extent operational) practices on the part of any system users and protect the system integrity and the market participants from the consequences of a default in the clearing structure.

Timely access to quality healthcare information during an outbreak plays an important role in curtailing its spread. The aim of this study was to investigate the information needs and seeking behavior of the general public in Singapore during the H1N1 pandemic. A pre-tested questionnaire was used for data collection. The convenience snowball sampling method was used and 260 working adults and tertiary-level students participated in this study. The most crucial information needs of a majority of the participants were: symptoms of H1N1, causes of the infection, preventive measures, and possible treatments. Data analysis also revealed that mass media such as television, newspapers, and radio were most frequently used for seeking the needed information. The use of human information sources was also quite high while only a small number of the respondents accessed online news and healthcare websites. About three-quarters of the participants indicated that the gathered information helped them to stay vigilant and take necessary precautionary measures. A major problem identified by the participants in using H1N1 information was the lack of understanding of certain terms used in public communications. This paper suggests certain measures for strengthening health information communication during future outbreaks.

Purpose: The purpose of this study was to verify the validity and reliability of the Type D Scale-14 (DS14). Methods: The participants were 288 patients who were diagnosed with angina pectoris, myocardial infarction, and hypertension. DS14 was developed by Denollet(2005) and consists of two domains, 7 items on negative affectivity (NA) and 7 items on social inhibition (SI). The Korean version of DS14 was developed through translation-reversed translation and a preliminary test. Data were collected using a self-report questionnaire. Cronbach $\alpha$ and Guttman split-half were used to test reliability and item analysis and factor analysis for validity. The SPSS program was used. Results: 35.8% of the participants were classified as Type D. Mean score for NA was 16.80 and for SI, 14.10 in Type D participants. For reliability of NA, Cronbach $\alpha$=0.771, and for SI, 0.707. Factor analysis on 12 items(numbers 1 & 3 were excluded as the corrected item-total correlations were below r=0.3) yielded two factors for NA (6 items) and SI (6 items). Number 7 in the NA domain was sorted into the SI domain. Conclusion: The results indicate, the cultural differences were between Europeans and Koreans. Repetition of the research is needed for generalization of DS14.

As information technology is more actively incorporated into automobiles, the role of IVIS (In-Vehicle Infotainment System) is becoming increasingly important for providing convenience and entertainment for drivers. However, using the infotainment systems while driving requires task switching and attending to two visual resources simultaneously. We simulated a setting where participants have to drive while interacting with the infotainment system and examined how task difficulty and motor cues impact driver task-switching and driving performance, specifically whether the effects of motor cues differ depending on task difficulty. For the infotainment display, we used two types of number array depending on the congruency between the digit repetition and the chunking unit, while task difficulty was manipulated by the size of the touch-keys. Participants were instructed to dial two numbers on the screen while we recorded the dialing time, lateral position, inter-key press intervals, and steering wheel control. We found that dialing time and lateral position were affected by task difficulty, while the type of number array had no effect. However, the inter-key press intervals between chunked numbers and steering wheel movement both increased when participants had to use an incongruent number array, which indicates that, if number digits are repeated, chunking is ignored by the drivers. Our findings indicate that, in a dual-task condition, motor cues offset the effect of chunking and can effectively signal the timing for task switching.

This study is to identify how the social support influences the impaired fasting glucose and type 2 diabetes as structural equation analysis reflects the health behavior and psychological path. It investigates participants who give consents to participate in the Korean Health Examine Cohort (KOEX), which collects surveys and biological samples at eight university hospitals nationwide. Of the 53,767 adults over 30 years of age enrolled in the 2nd to 7th KOEX study from 2004 to 2010 (1st to 7th), 18,618 participants with a history of chronic diseases related to type 2 diabetes, the main variable, were excluded. The number of participants were 34,316 with enough data on social support and diabetes, which are the main variables. The results show that social support affects health behaviors and lowers fasting blood sugar. Therefore, not only the management of risk factors of individuals, but also the practice of healthy behavior with the attention of social relations such as social support, etc., can prevent type 2 diabetes.

Objectives: The purpose of this study was to examine health information seeking behavior of people with cancer in terms of information seeking or avoiding behavior and the differences of the two groups in demographic and disease variables. Methods: Data were collected from October 21 to December 5 in 2013 from out-patient clinics of a university affiliated hospital in Suwon, Korea. One hundred (100) patients with cancer were participated in this study. Health Information National Trends Survey Questionnaires (National Cancer Institute, 2007) was used. Results: Three quarters (n=77) of the participants were in health information seeking group while 23% were in health information avoiding group. Participants who were female, higher education were more likely to seek health information than their counter parts. Among participants, a considerable number of cancer patients intentionally avoided information due to either the lack of accessibility of information source or the lack of credibility of information from the sources. Conclusion: Significant differences in gender and educational level were found in the two groups. Different approaches for both groups were necessary to increase information seeking behavior. And barriers of the information avoiding group should be considered in designing interventions to fill the gap between seekers and avoiders.

Background: In terms of physical performance, elastic tape (ET) is known to contribute to injury prevention and performance enhancement. Objects: This study aimed to compare and analyze the effect on lower extremity muscle activity of young adult women with and without ET during squats. Methods: In this study, six healthy, young women were recruited as participants in a university laboratory. Participants were allocated to two groups of three after measuring muscle activity in a pre-test, and the experiment was conducted for a total of two weeks (two sessions). First, 10 half squats were taped once in the first week, and 10 half squats were performed without taping in the second week. The other group did this in reverse and measured muscle activity after the squat was over. Results: As a result of this study, there was no significant difference in the quadriceps with or without ET (Z = -0.11, p > 0.05). Similarly, no significant difference was found in hamstring (Z = -0.31, p > 0.05). Conclusion: No beneficial effect was found on changes in muscle activity following ET application during squats. Further studies require randomized controlled trials that increase the number of participants and the intensity of the intervention, and measure pain, function, and performance rather than muscle properties depending on the biomechanical lifting mechanism.
