There are some studies about user's participation to reflect their desire and value on the planning of house by this time. These were constitution of unit space focused on the apartments, which is mostly theoretical. In architectural planning process, it takes time for continuous discussion and revision between architects and users. Also changes of plan must of necessity be so because of in or outside conditions. So, user's participation has its meaning that they take part in each step and portion of process faithfully on whole architectural processes. In this case, tenants of single houses were decided and they already buy building site and lay out rules jointly. With this circumstance I've researched a kind of test the reflection on various desires and its acceptance in each steps through completion of a construction work, which is based on their participation.

Thermal behavior of dickite was studied by thermal analysis, X-ray diffraction analysis, electron microprobe analysis, and scanning electron microscopy, Dickite has an endothermic peak at about$ 650^{\circ}C$ and an exothermic one at $960^{\circ}C$ in the differential thermal analysis. The endothermic reaction is assigned to the decomposition of dickite to meta-dickite. Hydroxyl radicals are removed from dickite structure by the reaction, resulting in the weight loss about 10.5~14.5% and appearance of a 14$\AA$ phase different from other kaolin minerals. The reaction slowly proceed in the range of $200^{\circ}C$. As the completion of decomposition, aciclular mullite forms at the expense of meta-dickite plates with random crystallographic relationship. Mullites have diverse silica versus alumina ratio. The exothermic reaction without weight loss seems to be due to the formation of spinel and amorphous silica. The spinel phase shows cryptocrystalline globular morphology accompanying a little amount of silica. From spinel phase shows cryptocrystalling globular morphology accompanying a little amount of silica. From this work, it is suggested that mullite is formed from meta-dickite much lower temperature than the reported one in the previous works.

A mega project such as an international airport construction generally consists of a number of sub-projects. Successful completion of this mega project requires project management information system(PMIS) because control and link of a number of component sub-projects is inevitable. Therefore, the role of PMIS should be more emphasized as the project is processed and managed by fast track concept where the design and construction work is performed concurrently. This study investigates and analyzes the present PMIS developed for the construction project of Inchon International airport. Based on this study, we can suggest the direction of PMIS for a mega project management and how to improve this kind of management information system.

Restorative effect of forest settings is an emerging issue in the field of forestry. It is also the central question facing those currently engaged in the psychotherapeutic interventions is which treatments work. This study was performed to investigate the efficacy of forest experience on alcoholics' depression. Among 531 participants in forest healing camps, 47 alcoholics who participated all three sessions of the camps were selected for this study. Using pre-test and post-test group design with Beck Depression Inventory (BDI), mean changes in alcoholics' depression by completion of the camp was measured. The result of this study indicated that the 3-session of forest camp played significant role in reducing participants depression levels (i.e., positive changes in depression scores).

Thyroid nodules are less common in children than in adults and their management is still controversial. The clinical presentations, operations, complications, histopathologic findings, and postoperative progressions of 34 pediatric patients that underwent thyroidectomy for palpable thyroid nodule at the Department of Surgery, Seoul National University Children Hospital between 1986 and 2003 were studied retrospectively by reviewing medical records and telephone interviews. The mean age of the patients was 11.8 years old. There were 23 females (67.6 %) and 11 males (32.4 %). Surgical indications were clinical need of histological confirmation (n=15), unresponsiveness to thyroxin replacement therapy (n=10), suggestion of the carcinoma on fine needle aspiration cytology (n=5), cosmetic purpose-a huge benign nodule (n=2), completion thyroidectomy for medullary thyroid carcinoma (n=1), and prophylactic thyroidectomy in a MENIIpatient (n=1). Unilateral Lobectomy was performed in 20 patients (57.1 %), subtotal thyroidectomy in 8 (22.9 %), total thyroidectomy in 5 (14.7 %), and completion thyroidectomy in 1 (2.9 %). Lymph node dissection was performed in 9 cases. Benign tumor was found in 23 patients (67.6 %), adenomatous goiter (n=18) and follicular adenoma (n=5). Malignant tumor was found in 11 children (32.4 %), 9 papillary carcinomas (26.5 %), and 2 medullary carcinomas (5.9 %). Of the 9 papillary carcinomas, 7 cases (77.8 %) had lymph node metastasis. No lymph node metastasis was found in 2 medullary carcinomas. Complications developed in 5 cases - transient hypocalcaemia (n=2), and temporary hoarseness (n=3). There was no mortality. Median follow-up period was 7.4 years (0.5-18 years). One patient showed recurrence in cervical lymph nodes 10 years after surgery and modified radical neck dissection was performed. Because of the high incidence of malignancy and advanced stage at initial presentation, more meticulous diagnostic work up is necessary for children with thyroid nodule, and more radical surgical treatment should be performed when malignant nodule is suggested.

A two-dimensional numerical experiment and field observations were conducted to evaluate changes in sea water movement and the water quality environment related to comprehensive projects of waterfront development around Kwangyang Bay on the south coast of Korea. Tidal flow velocities, especially in the western part of the bay, were considerably slower as a result of the development projects. Accordingly, the seawater exchange ratio reduced from 38.7% to 26.3%. The impact of dredging work on the water quality environment was much stronger than expected. Furthermore, after the completion of the industrial parks and container-exclusive wharfs, COD from the waste water treatment plant will be dispersed extensively into the adjacent water at a level of less than 0.1 mg/l for up to 142.5 $\textrm{km}^2$. Therefore, consistent monitoring and management of the water quality environment is strongly recommended.

This paper considers a single facility scheduling problem for the fabrication of components supporting the subsequent assembly into products. Each product consists of two types of components, one is common to all products and the other is unique to itself. The unique components are processed individually and the common components are processed in batches, and a distinct setup is incurred for the production of a batch of common components. Under the so-called “batch availability” environment, we propose an efficient dynamic programming(DP) procedure for the optimal sequencing and batching schedule with minimum total completion times of products in the situation that each product is said to be complete if both common and unique components of the product are finished. Computational results show that the proposed DB procedure is more efficient than the previous work which has considered the same problem as this paper.
