In this study, we analyzed determinant factors of leverage ratio and debt maturity for Korean firms in the simultaneous equation system using 2SLS (two stage least square) method under assumption that two variables are jointly determined in the capital structure decision. As a result of the analysis, we found that leverage ratio and debt maturity are positively related. Also, as for determinant factors of debt maturity, agency cost hypothesis, asset maturity matching hypothesis, signalling and liquidity risk hypothesis are all generally supported, and further leverage ratio are significantly positively related with firm size, but negatively related with default risk. However, when we divided samples into groups according to bank debt level and Chaebul affiliation, with contrast to existing study which worked on similar issues with OLS, we found no evidence supporting the argument that the information asymmetry problem is less severe in firms with more bank debt, whereas information asymmetry and financial constraint problems are more severe in non-Chaebul affiliated firms.

The purposes of this study were to understand how franchisor's influence strategies influenced franchisee's boundary spanning behaviors and how franchisor's entrepreneurship influenced franchisee's boundary spanning behaviors. This study also analyzed whether franchisor's entrepreneurship played a moderating role in the causal relationship between franchisor's influence strategies and franchisee's boundary spanning behaviors. Based on a total of 698 self-administered questionnaires obtained from franchisees(food-service unit owners or managers) in Korea, frequency analysis, exploratory factor analysis, reliability analysis and hierarchical regression analysis were conducted. The research findings showed results that firstly, promise (${\beta}$=0.292), threat (${\beta}$=-0.256), recommendation (${\beta}$=0.200), information exchange (${\beta}$=0.359), request(${\beta}$=-0.097) and legalistic plea(${\beta}$=-0.137) had a significant effect on franchisee's boundary spanning behaviors and secondly, franchisor's entrepreneurship had a significant positive effect on franchsee's boundary spanning behavior. In addition, the effects of franchisor's promise(${\beta}$=0.168) and threat(${\beta}$=-0.075) on franchisee's boundary spanning behaviors were found to be partially moderated by franchisor's entrepreneurship. Franchisees wanted franchisors to execute a high level of entrepreneurship and deliver a promise in an influence strategy. Limitations and future research directions were also discussed.

The purpose of this study was to look into the service quality of websites and the attributes of review information thereon as perceived by visitors thereto and to analyze the effect that the service quality of festival websites and informative usefulness of testimonials would have on the satisfaction with use, along with the effect that the satisfaction with use would have on behavioral intention. Based on the results of this study, we intended to present measures that could help strengthen the intention to spread positive word-of-mouth for festivals and to visit a festival through satisfaction with a festival's website. The festival selected to achieve the objectives of this study was the Yeongdeok Snow Crab Festival, which is one of the most renowned local food festivals in the Gyeongbuk region, having been held for 17 consecutive years, and has been selected as the top festival of Gyeongsangbuk-do for 4 consecutive years. We surveyed visitors to Yeongdeok Snow Crab Festival who had searched for information on the Yeongdeok Snow Crab Festival prior to its opening, as well as those who had participated in Yeongdeok Snow Crab Festival before. The results of this study showed that review information on a food festival website, service quality design, adequacy of substance, responsiveness to customers, and system capability were found to have a positive effect on behavioral intention through satisfaction with use. The findings suggest that it is crucial to manage the service quality of websites in order to stimulate interest in, and induce visits to, food festivals.

This study investigates perilla seed powder substituted for wheat flour in bread recipes with the amounts of 0%(control), 5%, 10%, 15%, and 20%. Perilla seed powder consists of 9.41% of moisture content, 9.14% of crude protein, 1.12% of crude fat, and 2.97% of crude ash. Sedimentation value and pelshenke value have decreased as the perilla content increased. The farinograph measurement result of the bread made with perilla seed powder showed that consistency, water absorption and tolerance index have increased as the perilla content increased. The amylograph measurement result of the bread made with perilla seed powder showed that T, P, H, F, P-H and F-H have decreased as the perilla content increased. Baking loss and specific loaf volume have decreased as the perilla content increased. The chromatic 'L' and 'b' values were reduced as more perilla was added to more pan bread, while the chromatic 'a' value increased. The texture measurement result showed that the hardness of bread have increased as the ingredient contents increased. Their cohesiveness, spinginess, and chewiness have decreased as the ingredient contents increased. Overall preference scores showed a high preference for the bread made with 15% perilla seed powder.

This study examined students' satisfaction with cyber education focused on the sections of consumer education in the University. The sample of this study was 94 students taking a 'Consumer Policy & Education' cyber course. The data were collected using structured questionnaires and analysed by descriptive statistics, frequency, percent, mean, SD, t-test and one-way ANOVA with Duncan test. The results of this study were as follows: First, the reason students took a cyber course was that it was easy to manage the course under "self-control". Second, they studied an average 1-2 hours for a one unit lecture at home on weekdays between 9 p.m. and midnight. Third, the students' satisfaction with cyber education showed a slight preference for the web based environment as opposed to the online lessons. Fourth, the biggest problem with taking a cyber course was that the students found it difficult to concentrate well on the lecture.

This study was conducted to reflect on the 30th anniversary of the Korean Home Economics Education Association(hereafter KHEEA) and to put forth a vision and a mission statement. To meet this purpose, first, reflection points were including the achievements of KHEEA for the last 30 years, the status of home economics education, themes of the bi-annual conferences of the Association, and the social contribution of home economics teachers. It was revealed that research and instruction in home economics education thrived by addressing social needs through its efforts in its 30 years of history. Second, a vision and a mission of home economics education were proposed in order to explore the prospective role of home economics education. The sharing of vision and mission functions as an ideal value and goal that home economics education as a profession should pursue, and it leads home economics professions to the direction that it should pursue. From this study, acting on a vision and a mission of home economics education, will lead to the development of a free individual, free society and sustainable environment, ultimately achieving the total well-being of individuals and families, society, and environment. This study reached the conclusion that the role of home economics education will become more prominent in the future society.

Morphological and population characteristics of the Cottus koreanus were investigated at Hoam stream from October 2015 and April 2016. This is the first record on C. koreanus not only from Hoam stream (the upstream region of Daejong stream, Gyeongsangbuk-do Gyeongju-si Yangbuk-myeon Hoam-ri) but also from the stream flowing into the Samcheogosip stream, in the southern part of East Sea, Korea. The distribution of C. koreanus ranged from Girim temple to Yongyeon waterfall, about 1.2 km, and the water surface were about $3,600m^2$. The population size was assumed to 1,656 individual number, 46 object per $100m^2$. The morphometric characteristics of C. koreanus in the Hoam stream and the Han river are very similar except that the population at Hoam stream shorter head length, ventral fin ray length, pectoral fin ray length and mouth width when compared with the population at Han river. Other than that, the two populations showed the same meristic characters. Frequency analysis of total length indicated that the group with 40~59 mm in total length was one year old, the 60~79 mm was two years old, and the group over 80 mm was three years old. The average number of eggs in the ovaries was estimated as 361 (239~468) per matured female. The number of matured eggs size in ovaries was $2.6{\pm}0.21$ (23.~3.1) mm and this species was large eggs type. Calculation of the length-weight relation of C. koreanus showed the value of constant a as 0.00001 and b as 3.01, and the Condition factor (K) was 1.26 an on average.

In this study, laboratory experiments and numerical simulations were conducted to test the performance of resonance power buoy system proposed by Kweon et al.(2010). The system is composed of a linear generator and a mooring buoy. The mover of the linear generator mainly has heave motion driven by vertical oscillation of the buoy. In this system, the velocity discrepancy between the mover and the buoy makes electricity. However, ocean wave energy as a natural resource around Korean peninsula is comparatively small and the driving force for producing electricity is not enough for commercialization. Therefore, it is necessary that the buoy motion be amplified by using resonance characteristics. In order to verify the resonance effects on the test power buoy, the experimental investigations were conducted in the large wave flume (length of 110 m, width of 8 m, maximum depth of 6 m) equipped with regular and random plunger wave generator. The resonance draft of test power buoy is designed for the corresponding period of incident wave, 1.96 sec. Regular wave test results show that the heave response amplitude operator(RAO) by a test buoy has the amplification of 5.66 times higher compared to the wave amplitude at the resonance period. Test results of random waves show that the buoy has the largest spectrum area of 20.73 times higher at the point of not the resonance period but the shorter one of 1.85 sec. Therefore this study suggests the resonance power buoy for wave power generation for commercial application in the case of the coastal and oceanic area with smaller wave energy.

Objectives: As suicide among the elderly population has been a critical issue in Korea, this study aimed to evaluate correlations of suicidal ideation with protective and risk factors among elderly who reside in a rural community. Methods: A total of 157 elders from Gyeongju city, who had attended senior centers in, were enrolled to answer questionnaires including the Geriatric Depression Scale Short Form-Korea and the Scale for Suicidal Ideation. Data were analyzed using SPSS 18.0K for Windows, and included t-test, Pearson correlation, and a three-step hierarchical multiple regression analyses. Results: Using the hierarchical regression analyses for predicting the elderly's suicidal ideation, male gender and social group variables were entered as predictors in the first step(adjusted $R^2$=0.107, P<0.05). Pain, ADLs, family support variables were not entered in the second step. Depression variable was the only predictor in the third step(adjusted $R^2$=0.384, P<0.001). Conclusions: Although this study confirmed the impact of depression on the suicidal ideation, elderly with risk factors including male gender and social isolation should receive a special attention from community health care professionals.
