The aims of this study is to analyze the purchasing behavior of customers purchasing seafood using internet shopping mall based on the sales data of Suhyup Shopping Mall in 2016. The research shows three facts. First, 46.1% of those customers marine products in Suhyup Shopping Mall are purchasing less than 2 times a year and 62.7% of them are purchasing less than 5 times a year. Seconds, The amount of purchases of marine products using Suhyup Shopping Mall is very small. The proportion of purchasers with less than ￦100,000 per year is 48.5%, and the proportion of customers with annual purchases of less than ￦300,000 is 68.2%. Last, Relatively strong items were found by region and age. Abortion was a relatively strong item in the 20s, and In the 30s, the aquatic product set was a relatively strong item. In the 60s are seashells / scallops / shellfish and other fish, 70s are dried yellow croaker, abalone, tile fish and other fish. In the 60s and 70s, the other fishes showed strong relative strengths in terms of quantity and amount. But There were no relatively strong items due to regional differences according to the metropolitan area and nonmetropolitan area.

In this study, we examined elementary school teachers' needs for environmental education (EE) in order to effectively implement EE in the elementary school. The participants were 113 elementary school teachers in Chungcheongnam-Do. Twenty items were adapted from the Environmental Education Needs test, and the teachers were asked to respond to each item on a 5-point Likert scale. For the items of the subcategory of EE training, teachers' preferences between the on-site and the online training were also asked. Although the teachers showed relatively strong needs for most items of both the subcategories of EE service and EE training, they exhibited stronger needs for the items related to the services and/or the content of training readily applicable to EE classes. Teachers preferred the online training to the on-site training in most items whereas their preferences to the on-site training tended to be relatively high in the items such as the use of local nonformal EE site, the development and the use of outdoor EE site, and the EE teaching strategies. Educational implications for the effective EE are discussed.

Quantitative association rules apply a binary association to the data which have the relatively strong quantitative attributions in a large database system. When a domain range of quantitative data which involve the significant meanings for the association is too broad, a domain requires to be divided into a proper interval which satisfies the minimum support for the generation of large interval items. The reliability of formulated rules is enormously influenced by the generation of large interval items. Therefore, this paper proposes a new method to efficiently generate the large interval items. The proposed method does not lose any meaningful intervals compared to other existing methods, provides the accurate large interval items which are close to the minimum support, and minimizes the loss of characteristics of data. In addition, since our method merges data where the frequency of data is high enough, it provides the fast run time compared with other methods for the broad quantitative domain. To verify the superiority of proposed method, the real national census data are used for the performance analysis and a Clunix HPC system is used for the parallel processing.

Objectives : The purpose of this study was to develop an employee's stress response scale (ESRS) and examine its validity and reliability. Methods : The study was conducted as follows : item generation, and test of validity and reliability. Items were developed via literature review, review of instruments, and data acquired from email-survey of counselors in the field of Employee Assistance Program (EAP). In order to test validity and reliability, data were collected from 400 employees. Results : The result of exploratory factor analysis of ESRS suggested 4 factor structures (work-related, anger, somatization, depression & anxiety) with a total of 25 items. ESRS showed a relatively strong positive correlation with Hospital Anxiety-Depression scale (HAD), Perceived Stress Scale (PSS), and Psychological Wellbeing Index (PWI), which showed ESRS had high convergent validity. Cronbach's ${\alpha}$ and test-retest reliability was .95 and .610 respectively. Conclusion : The ESRS is reliable and valid brief scale for measuring stress responses of employees. This scale would be useful in quantitatively evaluating job stress in workplace.

The purpose of this descriptive study was to assess sexual orientation and Knowledge and attitudes with regards to AIDS in military personnel, and to provide basic data for developing a further sex education program for them. The data were collected in June 2002 on 242 service members of A Branch of the Ground Army located in Chung-Chung Do Region. They responded to a survey questionnaire that consisted of 68 items: 14 items on sexual orientation. 39 items on knowledge about AIDS, and 15 items on attitudes toward AIDS. The data were analyzed using SAS program. The study results are as follows: 1. Sexual orientation of the military personnel 1) In terms of sexual orientaion, harassment and assault, only $26.4\%$ of the subjects responded as, 'know well'. Appropriate awareness of the legal liability was reported by $21.6\%$ of the subjects regarding sexual harassment and $78.1\%$ of the subjects regarding sexual assault. 2) Pre-marital cohabitant was supported by $89.2\%$ of the subjects. 3) The Korean military personnel showed liberal attitudes toward sexuality as $46.4\%$ of them reported having sexual-relationship with the dating partner is acceptable. 4) The attitudes of the most subjects toward homosexuality was found to be unfavorable. 5) Subjects were m the need of appropriate sex education. of which substantial knowledge on sexual intercourse was the most needy area. 2. Knowledge and attitudes toward AIDS of the military personnel 1) The subjects' level of knowledge on AIDS was relatively low, showing the average score of $22.31\pm7.23$ points (range: 0-39 points). The higher level of knowledge was reported by those who had high level of education, father alive. and less number of brothers in their family. 2) The subjects' attitudes toward AIDS was relatively positive. The attitude toward AIDS was also found to be more positive in those who had high level of education and less number of brothers. 3) There was a positive but weak correlation between knowledge and attitude toward AIDS. The study finding showed that the sexual orientaion of the Korean military personnel was moderately positive and liberal. However, their awareness of sexual harassment and assault and AIDS was still found to be low. As Korean enlisted military service men are likely to be in the ages with strong sexual desire, it may be important for them to have appropriate sexual orientation and attitudes toward AIDS. Therefore, it is recommended to develop further practical and sound sex education programs within the military unit in order to meet their education needs as well as to utilize sex education specialists as the instructors of those programs.

With the results of calculation for natural frequencies the reponses of forced coupled vibration of propulsion shafting system were investigated by the modal analysis method. For the forced vibration response analysis, the axial exciting forces, the axial damper/detuner, propeller exciting forces and damping coefficients were extensively considered. As the conclusion of this study, some items are cleared as follows.-The torsional vibration amplitudes are not influenced by the radial excitation forces of the crank shaft. -The axial vibration amplitudes are influenced by the tangential exciting forces as well as the radial exciting forces of the crank shaft. The increase of the amplitudes is observed in the speed range at the neighbourhood of any torsional critical speed. 1The closer the torsional and axial critical speed. the larger coupling effect becomes. -The axial exciting force of propeller is relatively strong comparing with axial exciting forces of cylinder gas pressure and oscillating inertia of reciprocating mechanism. Therefore, the following conclusions are obtained. -Torsional vibration calculation with the classical one dimensional model is still valid. -The influence of torsional excitation at each crank upon the axial vibration is improtant. especially in the neighbourhood of a torsional critical speed. That means that the calculation of axial vibration with the classical one dimensional model is inaccurate in most of cases.

As the conclusion of this study, some items are cleared as next. - The torsional amplitudes are not influenced by the radial excitation forces. - The axial vibrational amplitudes are influenced by the tangential exciting forces. An increase of amplitude is observed for the speed range in the neighbourhood of any torsional critical speed. - The coupling effect becomes larger if torsional and axial critical speed are closer together. - The axial exciting force of propeller is relatively strong, comparing with those of axial forces of cylinder gas pressure and oscillating inertia of reciprocating mechanism. Therefore, as a resume one can say, that- Torsional vibration calculation with the classical one dimension model is still valid. - The influence of torsional excitation at each crank upon the axial vibration is impotent, especially in the neighbourhood of a torsional critical speed. That means that the calculation of axial vibration with the classical one dimension model is insufficient in most of cases. - The torsional exciting torque of propeller can be neglected in most of cases. But, the axial exciting forces of propeller can not be neglected for calculating axial vibration of propulsion shafting.

In this review quality improvement, new products and processing of ginseng are discussed. Ginseng products are generally classified into two types; the dried product without significant change in original shape of fresh ginseng and various processed ginseng products in liquid or solid types prepared by addition of either ginseng extract of ground powder. The dried ginsengs are generally made 4 years old fresh ginseng roots for production of white ginseng and 6 years old ones for red ginseng. The processed ginseng products, such as ginseng drinks, extracts, teas, powders, capsules or tablets are prepared by addition of extract or powder of the ginseng roots which contain relatively high amount of saponin. At present, more than 200 items of 40 types of products are commercially available in over 70 countries in the world, Since consummers preference on the quality of ginseng products as an health food differs with their cultural background of each country, new products development and quality improvement should be investigated with concerning the particular preference of the consummers of various country. It has been generally found that the Orientals has higher product acceptance on strong ginseng flavor while the Westerners generally prefers the products having mild ginseng odor and taste. Recently consummers are asking for supplemented type of ginseng products with various medical herbs and vital materials instead of ginseng alone. Therefore future work on product development should be emphasized to meet the consummers demand and preference.

According to a recent survey, the sales amount of luxuries and imitations is getting larger. Especially young consumers in 2,30's have a strong desire to own luxuries, so I tried to build a theoretical base on the 20's consuming trend. Meanwhile, targeting university students who represent consumers in 20's, I investigated the recognition of luxuries, shopping experience, main shopping items, monthly spending money, and future purchase intention. I also investigated shopping experience of imitation, main shopping items, purchase reasons, and future purchase intention. I tried to suggest lots of academic and practical implications in marketing strategy building of luxury brand, aiming young consumers in 20's. On the social-psychological view point, young generation have relatively weak sense of control or self-efficacy. So, they are easily submerged in conspicuous consumption by the atmosphere around. As a result of empirical research, I found that Korean students recognized luxuries as excellent in quality, or the world famous brand. In particular, statistically significant gender difference was shown in the luxuries characteristics as the high-quality brand for male students and the world famous brand for female students. Most respondents have experience buying luxuries. And more monthly spending money, more experience they have. Respondents' purchased items were in order of fashion goods, clothing, watches/jewelry, cosmetics/perfume. And the statistically significant differences between gender and monthly spending money were shown. Not many respondents purchased luxuries imitations, and main purchased items were fashion goods. Most of purchase motives are price over quality and economy reason. The phenomena that the respondents of relatively high levels of monthly spending money had lots of luxuries imitations shopping experiences is interesting. Female students showed higher purchase intention for luxuries and imitations than male students. There was no statistically significant difference in grade level, but was found something interesting in monthly spending money. As monthly spending money increased, the purchase intention of luxuries increased, but the purchase intention of luxuries imitations decreased. However, non-linear trend was shown in the specific allowance level. This is replicate of the luxuries imitations purchase experience. Following studies will be needed for the exact interpretation for this. This study is an exploratory and descriptive, but can provide lots of fruitful academic and practical implications in formulating luxuries marketing strategies.
