Dahoejangs in the Joseon Dynasty were craftsmen who belonged in the Gyeonggongjang in Hansung government office. Out of 2,841 craftsmen who specialized in 129 types of work, 1 of them were Dahoejangs. Dahoejangs were craftsmen who made cords. However it was not passed down and currently Maedeupjangs are making cords and making Maedeup with the cords they have made. In the Uigwes the composition of Dahoejangs number and types of tools used in creating good for ceremonies are indicated. This study has found records of Dahoejangs from 50 Uigwes. The tools used were indicated as Haesagee, Hapsagee, Hapseongee, Yeonsagee, Sangsagee, Dahoegee, Yungjapan and some others. Haesagee is a tool that winds thread from a skein to a spool. Hapsagee is a tool that combines more than two yarns together. Hapseon is for combining thicker threads. Yeosagee is not a process of scouring for refining, but is assumed to be a tool to twisting yarn. There are no information left about the shape or working methods of Sangsagee but it is considered to be a tool for doubling several threads together. Based on the existing artifacts and painting of Dahoe, it is assumed that threads were woven on usually a round plate or bowl. Youngjapan is considered to be a tool for making tassels. This shows that Dahoejangs made tassels and it was completely separate from making Maedeups. There, it is evident that Dahoejangs made cords as well as tassels but the work of Maedeupjang were constricted to only making Maedeup with the cords given to them.
The purposes of this study were to identify customer expectation, perception and satisfaction of foodservice quality to analyze the influencing factors on foodservice quality and finally to provide basic information for the improvement of foodservice quality. A survey of 4 factory foodservices was undertaken and detailed information was collected from 675 respondents. Statistical data analysis was completed using the SPSS package program for descriptive analysis, t-test and one-way ANOVA. Male had higher scores than female in perceptions of foods and services, and the differences were statistically significant. As analysis of expectation, perception and satisfaction result of age, expectation and perception were statistically significant, and mostly expectation and perception increased according as age increased. Expectation and perception showed statistical differences by marital status. Married people had higher scores in expectation and perception of food and service than single. According to family type, respondents living alone showed lower scores in expectation and perception of food and service than those living with family or relatives. Conversely, living alone had high expectation on service. As analysis of work type, office workers showed higher scores of service expectation, food and service perception than production workers. As education level increased, food and service expectation and perception increased mostly. As analysis of work post, food and service expectation and perception increased as work post raised. Meanwhile, married people had higher scores in service quality of satisfaction than single. Result of the study can be summarized as follows the analysis of expectation, perception and satisfaction of foodservice quality, the Quadrant of food and service quality expectation and perception according to demographic variables. Expectation, perception and satisfaction scores of foodservice attributes according to work type. The distribution of attributes with satisfyingly significant difference in grid.
New occupational types, suitable for the elderly, have been developed in order to extend job opportunities for that demographic. However, it was mainly done from the perspective of the urban elderly and did not take into account the rural elderly's needs and the special conditions in rural areas. Especially, as 53.4% of the rural elderly 60 years old and over has engaged in economic activities and 88.7% of them are working in the field of agriculture or forestry, the development on the new kinds of job for the rural elderly is more meaningful as secondary jobs rather than as new occupations. Therefore, this study aimed at developing the new kinds of occupation suitable for the rural elderly. For this purpose, data were collected from 279 elderly farmers 60 years old and over working currently or have ever worked in something other than farming work. Questionnaires were composed to measure preferences for jobs by work characteristics and evaluations on the appropriateness of the jobs for the elderly selected by the Ministry of Labor in Korea. The results showed that the rural elderly preferred work doing at home, together with the elderly, in groups, and light physical labor to technical or office work that must commute regularly. Also, they evaluated that most of the occupations suitable for the elderly announced by the Ministry of Labor were more suitable for the male than the female elderly. Based on these findings, this study selected 18 kinds of individual and 11 common jobs by sex. It may contribute to creating job opportunities for the rural elderly by applying it to the policy or extension, and to revitalizing the rural elderly's lives and increasing their incomes.

Objectives: The purpose of this study was to evaluate the characteristics of worker exposure to hazardous chemical substances and propose the direction of work environment management for protecting worker's health in the semiconductor assembly process. Methods: Four assembly lines at two semiconductor manufacturing companies were selected for this study. We investigated the types of chemicals that were used and generated during the assembly process, and evaluated the workers' exposure levels to hazardous chemicals such as benzene and formaldehyde and the current work environment management in the semiconductor assembly process. Results: Most of the chemicals used at the assembly process are complex mixtures with high molecular weight such as adhesives and epoxy molding compounds(EMCs). These complex mixtures are stable when they are used at room temperature. However workers can be exposed to volatile organic compounds(VOCs) such as benzene and formaldehyde when they are used at high temperature over $100^{\circ}C$. The concentration levels of benzene and formaldehyde in chip molding process were higher than other processes. The reason was that by-products were generated during the mold process due to thermal decomposition of EMC and machine cleaner at the process temperature($180^{\circ}C$). Conclusions: Most of the employees working at semiconductor assembly process are exposed directly or indirectly to various chemicals. Although the concentration levels are very lower than occupational exposure limits, workers can be exposed to carcinogens such as benzene and formaldehyde. Therefore, workers employed in the semiconductor assembly process should be informed of these exposure characteristics.
This study was conducted to investigate the consumers' Dining-out preference and behavior for the chilled meat consumption strategy . A total of 328 persons in Seoul, Kyunggi areas were selected by stratified random sampling method and were responded to this study questionnaire which was composed of six parts with 65 statements about chilled meat consumption. 1. The frequency of Dining-out is characterized that 'once a month' is the highest pattern of consumers(46.3%) : In that cases, the married people showed 'once a month'(52.7%) and 'once biweekly'(23.3%), but the unmarried people showed the more frequent pattern as 'once a week'(27.3%) and 'twice a week'(27.3%). And the frequency of Dining-out in relation with the education level revealed that 'the graduate people' are the highest (37.5%). 2. Generally the first food for the Dining-out is 'Kalbi'(26.2%), and the others were 'pork grilling','chilled meat grilling','fish sasimi','chinese foods','pizza' etc.... But there were some variation in relation with incomes and housing types: For the agriculture/physical labor class, they prefers the 'pork griling'(25.0%), the office work class prefers the 'Kalbi' For the house-owner group, they prefers the 'Kalbi', but the house-renting/lodging group, they prefer the 'chinese food' or 'pork grilling' etc.... 3. In choosing the Dining-out place,'quality of food'(54.3%) and 'hygiene'(21.0%) were rated as the first important factor. 4.'Soups', 'Noodles' and 'Cooked rice in casserole' were chosen as good lunch menu : for male, they prefer the 'Soups', but females prefer 'Cooked rice in casserole'. 5. People with commercials/services(44.7%) and agriculture/physical labor(50.0%) ate their lunch in private restaurant, but peoples in the office work(57.0%)/public service personnel(70.4%) and industry use refectory; and it showed significant difference. 6. Consumers prefer the chilled meat as a Dining-out menu, but they didn't recognize the difference between chilled meat and frozen meat 7. For Dining-out menu, many people proper the beef, but the price of beef was so high than pork, agriculture/physical labor class choose the pork grilling instead of beef : commercials/services/office worker prefer the beef chilled meat . 8. The first admirable cooking method for chilled meat is direct radiation grilling with charcoal and many of consumers prefer tender, marbling, some chewy and juicy, flavor, soft as a quality of meat but physical labor class prefer the some tough and chewy texture.
Many domestic users complain about severe pain to the waist, neck, and shoulder as well as work performance because the domestic chair design was developed with western anthropometry dimension and design criteria. Ergonomic design standards are needed for office chair design to reduce stress and poor physical posture for various user body types. In this study, we have suggested design dimensions recommended from previous studies and Korean anthropometry data. We also have reviewed users' preference dimension through measured subjects and analyzed differences between users' preference dimension and the previous design criteria to verify physical appropriateness. We evaluated general office chairs and adjustable chairs which can adjust to fit each person. we also analyzed how each design dimension was reached and affected the human body by evaluation of physical discomfort and comfort. We have found seat height is very important in a workstation. If the seat height is high, it effects the thigh. If width, height, and angle of the backrest are wrong, fatigue to the shoulder, neck, and waist, etc.. As a result of this experiment, we suggested that the height of a seat for Koreans be 425mm for the fixed type and 365-484mm for the adjustable type. Also other design recommendations were suggested in the thesis. In conclusion, our research will be very important in the database because it provides adjustable ranges to fit user's body types in the various design fields.

In respond to the demand of an open, fair, transparent, and efficient environment for procurement, many governments have incorporated the use of internet in their procurement systems with online procurement (e-procurement). Given the different policies and laws which have to be complied with, the practice of government e-procurement system varies from one country to another. Thus, experiences in running e-procurement will vary as well. The achievements and obstacles of one country's experience will be a constructive reference for other countries in establishing e-procurement system. In this regard, government e-procurement system practices in two Southeast Asia countries i.e., Thailand and Indonesia particularly in public works are consecutively presented and finally compared in this paper. The government of Thailand has applied Online Auctions (e-Auctions) as the national procurement practice since 2005 and performed the e-Auctions in two types: Reverse Auction and Sealed Bid Auction. Contrary to the common practice of e-procurement, the Thai government, with some rationales, runs the bid documents obtaining manually as well as qualification and technical documents submission and holding the e-Auctions at bidding office. Whereas Indonesian government runs Online Sealed Bid Bidding (e-Procurement) and most of the bidding stages are performed electronically except bid evaluation for both technical and financial. The advantages and drawbacks of these two e-procurement practices are discussed as well as improvements that have to be made for successful of e-procurement.

Ball reducer (HERB Drive: High Efficient Wave Rolling Ball Drive) with waved grooves has many advantages over other types of reducers for high-reduction ratio, low noise and low energy loss, etc. The mechanism of force transmission is very similar to that of cam and follower in automobile valve train system especially in contact behaviors. In this study, we have investigated the traces of contact between ball and outer ring, and the dynamic contact behaviors of elastohydodynamic lubrication(EHL) with a certain reduction ratio. In order to verify the contact behaviors between ball and outer ring for the critical endurance lift, the contact velocity and load are computed for a cycle. During some intervals of a cycle, the contact velocity reverses its direction very suddenly. It is expected that changing the contact direction causes undesirable endurance performance because EHL film frequently col lapse at the moment of velocity reversal. From the computational investigation in this work, we hope to predict similar contact damages in other machinery due to this kind of contact behaviors, which is very typical in many contact phenomena.
