The purpose of this study was to examine the structural relationships among the motives on Social Networking Service(SNS) of restaurants customers, attitude toward SNS, and intention to use. Using a quota sampling method, data were collected from 273 residents of the whole country who were in their 10~50s. The PASW Statistics 18.0 and AMOS 17.0 statistical package were used for the analysis. The hypothesized relationships of the model were tested simultaneously using a structural equation model(SEM). The proposed model provided an adequate fit to the data, ${\chi}^2$=287.558(df=155) p<.000, CMIN/df=1.855 GFI=0.905 NFI=0.887, IFI=0.944, TLI=0.931, CFI=0.943, RMSEA=0.056, RMR=0.025. The results showed that recreational motive(${\beta}$=0.238) and functional motive(${\beta}$=0.467) had a positive effect on the attitude toward SNS. Attitude had a positive effect on the intention of using SNS. The results enable the marketers of restaurants to develop SNS marketing strategies that motivate customers.
Vinyl chloride (VC) and vinylidene chloride (VDC), which may be present in poly(vinyl chloride) (PVC) and poly(vinylidene chloride) (PVDC) food packaging, were analyzed by using a headspace-gas chromatograph (GC)/mass spectrometer (MS) equipped with a PLOT Q column. 1-Chloropropane (1-CP) was used as an internal standard. The determinations of VC and VDC were carried out by monitoring the characteristic ions for each compound: m/z=61, 62, 64 and m/z=61, 96, 98, respectively. The method validated in this study can be suitable for the compliance test of EU regulation. Among 103 food packaging samples, VC and VDC were not detected, except in one PVDC food package. However, the detected level of VDC in the sample was below the EU regulatory specific limitation.

The aims of this study were to compare genetic distances among 14 Phalaenopsis varieties using simple sequence repeat (SSR) and sequence-related amplified polymorphism (SRAP) marker systems and to determine the discrimination using SSR. A total of 111 SSR primers and 30 SRAP combinations were initially screened. Twelve SSR primers and thirty SRAP combinations showed high polymorphism among the 14 Phalaenopsis varieties including domestic breeding varieties, conserved in National Institute of Horticultural & Herbal Science (NIHHS). The amplified DNA fragments were separated by denaturing acrylamide gels and detected by silver staining method. A total of 474 polymorphic bands, including 55 by SSRs and 419 by SRAPs, were identified and used for genetic diversity analysis. Polymorphic bands were scored for calculating a simple matching coefficient of genetic similarity and cluster analysis with multi-variate statistical package (MVSP) 3.1. Fourteen Phalaenopsis varieties were classified into three major groups at similarity coefficient value of 0.683 and 0.66 using SRAP and SSR, respectively. Also we could discriminate these domestic breeding Palaenopsis varieties using only SSR 20 and SSR 22. The results indicate that SSR analysis is effective for discrimination among Phalaenopsis varieties and SRAP is useful for genetic diversity when there is no sequence information. These studied SSR and SRAP markers will be useful tools for genotype identification, germplasm conservation and genetic relationship study in Phalaenopsis.
This research was carried out to get the basic information on the current situation of personal computer utilization for poultry farm management, and the results obtained could be used in developing of the software system for the poultry farm management. Survey method by interview and mail was adopted to carry out the research, and the total number of data used to statistical analyses was k6 poultry farmers. 1. The ratio of the poultry farmers who had the personal computer(P/C) was about 25%, and the most of the layer farmers from age 30 to 40 who manage the flock size 20,000 or above had the P/C. 2. About 70% of the farmers who had P/C have bought the system after 1993, and 83% of those farmers had the P/C-486 or above level system. They bought the P/C with intent to apply it to farm management(39%) and education for children(31%). 3. About 50% of the farmers who had P/C obtained the relevant knowledge for operating computer system by themselves, and the 33% of the P/C-possessed farmers used P/C for word-processor. 4. About 35% of the farmers who had P/C applied their system to analyse the management analyses, and the sarne ratio of the farmers answered that they didn't apply the system to their farm management. 5. About 25% of the farmers who had P/C used package software, and the company which installed the automated cage system offered the software. 6. Most of the farmers considered the computerization of the farm management positively, and they answered that they will apply P/C to their management actively from now on. 7. About 56% of the farmers didn't think that they had sufficient knowledge for operating computer system, and a quarter of them pointed that the difficulty of the buying software for poultry farm management was the most biggest problem to spread out the computerization in the poultry farm. 8. Most of the poultry farmers didn't buy P/C because they didn't have the relevant knowledge for computer system, but they wanted to learn basic knowledge for computer, and they had the intention to apply computer to their management positively. In order to expand the computerization for poultry farm management, appropriate education system for the farmers from age 30 to 40 who manage the flock size 20,000 or above and the development of the software that could be applied to poultry farm management on the spot efficiently should be made.
In order to designate a present status necessary for establishment of preventive measures and guidelines of health education against hepatitis B in the course of secondary school education, knowledge and practice toward hepatitis B virus infection was surveyed by a questionnare method on total of 4,855 college entrants in the academic year of 1987 and analyzed the data collected using IBM PC(Trigem 88-II) with SAS package program. About two per cent of college entrants had past history of HBV infections not showing any difference between both sexes and geographical regions. About one third(33.7%) of total students had tested hepatitis B surface antigen(HBsAg), only 4% had tested hepatitis B surface antibody(HBsAb) and vaccination rate amounted to 24.6%, one fourth of total subjects. Both serological tests and vaccination were most commonly performed during adolescence, showing higher rates in female students than in male students. The rates also seemed to be higher in those from urban cities than those from rural cities. Students who had acquired correct knowledge that hepatitis B was infected by virus were amounted to 78.5% of college entrants, and remaining 21.5% had misunderstood that rickettsia, bacteria, fungi or parasites were causal agents. Female students were better aware of the causal agents than male students but there was no difference between places of growth. As for mode of transmission of HBV, 51.5% of male students and 47.7% of female students had correct knowledge. A very few student had known that fact that HBV was transmitted by body fluids such as tear(6.9%), nasal discharge(10.1%) and semen or vaginal secretion(19.2%) and majority(75%) of students had misunderstood that hepatitis B virus would be transmitted per os through food ingestion. Approximately one half(48.9%) of college entrants had knew correctly whom to be vaccinated. Approximately one half of the students knew that hepatr;ma(57.8%) and liver cirrhosis(57.4%) might complicate with hepatitis B virus infection, whereas 12.0% of the students responded that bronchitis was one of the complications of hepatitis B infection. In summary of the above results, we highly recommend that health education program for eradication of hepatitis B virus infection should be introduced in curricula of secondary school education in this country.

Main machinery in the factory have various digital indicator to display its operating data for the manager. It is useful to control these datum at the remote office for factory automation in order to increase machine productivity. It is easy to use Ethernet infrastructure for remote communication. But most of all machinery in domestic factories still support RS232c or RS485 serial communication way. In this case to control machinery datum on the ethernet base, it is need to change RS232C or RS485 data to ethernet base. In this paper, in order to develop a remote progress management system through the wireless Internet, we show a design method to make easy maintenance by developing the system with both the JAVA language and RxTx Package for RS232c serial communication. For the system implementation, we added the digital indicator connect with a thermo couple to a machine which provide the real time status data of temperature. To connect machines management server program, we set up a convertor to change the RS485 data to the RS232c and also another convertor to change the RS232c data to wireless ethernet.

The survey was conducted between October 1 to October 15, 2011 among 294 male and female adults aged 19 years and over in Seoul and Gyeonggi-do areas. The gender distribution of the subjects was 33.3% males and 66.7% females. For a perception on traditional dietary life, the degree for enjoying meals with cooked rice as the staple food revealed that 32.3% of the subjects responded 'strongly agree'. The intake frequency of traditional soy sauce and soybean paste products in the subjects of the study showed that in the case of doenjang, 49.7% of the participants consumed it twice a week and 21.4% consumed it once a week. For gochujang, 59.9% consumed it twice a week and 19.0% consumed it once a week. The perception on the preparation method for traditional soy sauce and soybean paste products showed a low level for traditional soy sauce and soybean paste products. The reason for purchasing traditional foods showed that 77.6% of the subjects made purchases for convenience and 8.2% purchased it for its small package. For the subjects, the priority for purchasing traditional soy sauce and soybean paste products was as follows: in the first rank, ingredients & origin made up 33.7% and price comprised of 26.2% of the priority. Regarding satisfaction for soy sauce and soybean paste products in the market, the degree of satisfaction was high for gochujang. With regard to gender difference, female subjects showed a significantly lower satisfaction for cheonggukjang and kuk-ganjang, and a significantly higher satisfaction for chin-ganjang, compared to the male subjects. The results of the study depicted that consumer's requirement was high for traditional soy sauce and soybean paste products in the market, particularly for the safety of the products in the market. Consumer satisfaction was relatively positive yet, some efforts are needed in order to improve the quality of cheonggukjang and kuk-ganjang.

The purpose of this study was to understand clothing condition of elderly men focusing on somatotype variation and satisfaction with ready-to-wear and to provide basic data in designing ready-to-wrar for the elderly men. The questionnaire method was used and one-to-one interviews were held for the elderly residents in Seoul, Deajon, Jonju, and Yeosu areas. The total of 275 questionnaires (from 148 elderly men in the 60's, 99 in the 70's and 28 in the 80's) were collected and used for statistics. SAS package was used for the statistics and the statistics were based on frequency, X2-test, ANOVA, Duncan's multifle range test. The results of the study were as follows; 1) Height (p< .05), weight (p< .001) and Rohrer index (p< .05) decreased significantly with ageing 2) The somatotypes of 75.6% were changed and the 70's 8t the 80's showed significantly (p< .05) higher changing rate compared to the 60's and more changes took place significantly (p< .001) with ageing. 3) The most preferred out wear was suit & tie and next was jumper or shirt. 4) For the mode of getting suit, the highest number 55.3%) purchased ready-to-wear, next (32.0%) was tailored and the least (12.7%) neither purchased nor tailored. The percentage of buying ready-to-wear significantly (p< .01) decreased with ageing. The main reason for getting tailor-made was not well fitting of ready-to-wear (20.7% out of 32.0%). And for the mode of getting suit, there was significant differance with income (p< .001) and pocket money (p< .01). 5) The most important factors in suit and shirt werefirst, size (fitness) and second, comfort in movement. 6) For the wearing feeling of suit, 55.3% showed discomfort. There was significant difference according to the age (p< .05) and pocket money (p< .05). The Discomfort increased with ageing and less pocket money. 7) 62.4% answered it uneasy to Pick out well fitting If comfortable suit. This showed their dissatisfaction with ready-to-wear. 8) As for the items of not well fitting, 64.4% answered in jacket, 60.8% in trousers, 46.0% in shirt. The above result shows that elderly men's somatotype changes as they age, suit is found uncomfortable and it's not easy for elders to pick out comfortable ready-to-wear. So, they seem to have a certain dissatisfaction in ready to wear. Therefore, there is a need for reorganization of size and developing pattern design according to measurement of elderly men.
