Amid the rapid transitions in both local and international markets, the Korean dental industry is facing more challenges than at any time in its history. This paper tried to address some of the key issues faced by the industry as well as the policy issues and I direction of implementation that the Korean Dental Association (KDA) is expected to tackle. First, the direction of reforming the country's health insurance system was examined with emphasis on the expected changes in and improvement of the fee-for-service reimbursement system (FFSRS) and medical reimbursement system (MRS). With FFSRS, the most urgent issue would be ameliorating the current lop-sided, unreasonable reimbursement system that prevents suppliers from voicing their opinions. To help achieve that goal, the limited authority and responsibility of the president of National Health Insurance Corporation (NHIC) as one of the contract-making parties must be clarified. In addition, the functions of NHIC's Health Insurance Finance Committee must be restricted; at the same time, the panel organization of the Health Insurance Policy Review Committee needs to be reformed to embrace greater democracy. As with MRS, the government is considering a block budget bill to help promote efficiency in employing and managing the health insurance fund. Policymakers must understand that the implementation of such proposal could exacerbate an already dire situation. Improving MRS requires meeting the following preconditions: (a) the structurally vicious cycle of small charge-small salary needs to be resolved, and a certain percentage of fee raise must be guaranteed on a yearly basis to help adjust the fee system to a more realistic level; (b) the supply-and-demand balance in producing health care professionals must be improved including the prevention of oversupply of doctors, nurses, etc., and; (c) institutional strategies must be provided to enhance the quality of medical care and ensure academic advancement in health care disciplines.

Objective: This research investigates how to increase the quality of medical service and supply high quality of medical service to patients. By using Kano Model theory we examines what medical service attributes the hospital would be conducted preferentially for patient's satisfaction and provides informations of management strategies for hospitals. Method: To study patients' perception of medical service quality, first we performed pilot test to derive 30 medical service attributes. With 30 medical service attributes, we conducted survey of 300 subjects who have experienced medical services in 6 months. To examine patients' conception of medical services, a modified Kano's questionnaire using 5 scale is applied. Finally we calculated SI(Satisfaction index) and DI(Dissatisfaction index) and PCSI(Potential Customer Satisfaction Improvement) index with Kano's Model analysis results. Key Findings: We found that the quality of medical service categorized in 15 one-dimensional elements, 9 must-be elements and 6 indifferent elements. Moreover the attribute of gives prompt services and have patient's best interest at heart scored the highest SI, whereas the attributes of accurate and precise medical service, exact records, enough explanation and polite attitudes are the highest score of DI. And also good explanation of the bill scored the highest PCSI. In this study findings indicate that while medical service providers try to increase patients' satisfaction by improving hospital's environments, patients' perception of trust and good interpersonal relationships with medical service providers have strong and positive impact on patients' satisfaction.

Product Lifecycle Management (PLM) is an integrated business approach to manage the creation and distribution of product information throughout the product development process. From the product perspective, PLM encompasses a holistic approach to product development and product information management. It supports the integrated product information in conjunction with the efficient product structures and BOM (Bill Of Material), user interfaces, proper functions, design processes and enterprise integration. Therefore, PLM should not only satisfy required functions as an enterprise software but also offer a systematic method for the efficient application from the initial stage of its development. Recently, many shipyards have been considering the PLM as a strategic solution to get the efficient management of product information such as 3-D models, BOM, drawings, documents, and the other product data. Though many studies on PLM are performed, most of them are performed in a function-based approach adequate for mass productive assembly industries. It could not help having limitations on applying the proper PLM system to the shipbuilding business since the requirements of shipbuilding PLM are too diverse and huge to design the architecture. This study presents the PLM framework which effectively reflects the diverse requirements of shipbuilding PLM. In order to get the macroscopic architecture of shipbuilding PLM, authors suggest the four-tier architecture model which considers the various requirements collected from shipyards. Entities of ship design data are modeled BOM in terms of product structure and hierarchical class diagram. Applicable functions of shipbuilding PLM are also investigated by analysis of issues of ship design. Finally, by reflecting the design process of shipbuilding, To-Be ship design procedure cooperated with the suggested PLM framework has been summarized.

Bill of material (BOM), which structurally represents the relation among parts constructing a product, is usually created when enterprises start to develop a new product. And it is shown as various types of BOM according to business needs and usage such as eBOM (engineering BOM), gBOM (green BOM), mBOM (manufacturing BOM), pBOM (process BOM), etc. eBOM, generally called BOM and created in the design stage of the new product, includes the drawing information of parts in the view of product function. eBOM is extended to gBOM adding the material information of parts to cope with international regulations for environment. eBOM is transformed to mBOM, which includes manufacturing sequence of parts and adds some parts required to fabricate parts and to assemble the product. mBOM is also extended to pBOM adding the process information of each part and additional assembly processes. This study introduces the concept of multi-BOM covering eBOM, gBOM, mBOM and pBOM, and proposes an advanced way to manage product data using multi-BOM system. The multi-BOM system proposed is to manage their relations using transformation function of BOM and master information of all BOMs.

The completion of the Bakun Diversion Tunnel is subsequently to the Main Dam construction. Therefore, the completion date is very important for the Bakun Hydroelectric Project. Generally, the tunnel lining work as a finishing phase of the tunnelling project occupies a important portion as well as an excavation and a support work of the tunnels in respect to the construction cost and period. Internal section of Bakun Diversion Tunnel is designed circular shape to reduce the roughness of the water flow with 12 meters in diameter of total length 4314.6 meters of 3 tunnels. The lining thickness is varied between 500 mm and 700 mm depending on the structural condition. From the original Tender design of the Bakun tunnels, the required quantity of steel bars was 5,985 ton designed by Reinforced Concrete (RC) through the entire tunnel linings. During the detail design stage by the consideration of the rock conditions and various load conditions, we could suggest five kinds of RC lining type including plain concrete lining type. Through the detail design modification, we could reduce the required amount of steel bars to 2,178 ton, as a half of original Bill of Quantity. Finally, this design modification give us the time and cost saving effect to catch up the construction progress in time.

This study was carried out to investigate the effects of climatic conditions on the budding of buds and the growth of shoots of mulberry (Morus alba L.) at Suwon for the period of six years from 1978 to 1983. The results are summarized as follows. 1. The period that influenced most greatly on mulberry budding and foliating of it's buds was from late part of March to middle part of April in the district of Suwon, Korea. 2. Temperatures in soil 20cm deep during the period from late part of March to middle part of April had high correlations with budding dates. 3. It was disclosed that the budding date had high correlations with the date of bud shaped swallow-bill (r=0.9861**), date of the third leaf(r=0.97**), and date of the fifth leaf(r=0.96**), respectively. 4. The higher the average temperature of April became, the longer the length of shoots became. 5. The earlier the budding date and foliating date came, the larger the leaf yield became. However, with excessive amount of precipitation after early budding and foliating, the leaf yield was not increased in proportional. 6. The longer the growing period of the shoots became, the larger the leaf yield became.
