According to "The Renewable Energy 3020 Implementation Plan", offshore wind power accounts for 12 GW of the total new capacity of 48.7 GW. Like the south-west 2.5 GW offshore wind farm case, government-led development has had difficulty in securing the residents' acceptability. This study contributes to the study of local acceptance by analyzing the perceptions of Maldo residents. To this end, in-depth interviews were conducted with the head of a village and fishing village chief, and the entire contents of the interview were revised and analyzed. The cognitive structure of the stakeholders could be confirmed using semantic network analysis, which analyzes the network structure among words. Based on the analysis results, focusing on the identity frames related to the compensation process from previous national projects, gain vs. loss frames act as the dominant frame in terms of profits from offshore wind turbines. To invigorate offshore wind farms, the policy implications as follows. First, a negotiation organization should be organized to deal with strategic opposition by fishes. Second, installing offshore wind farms on a public water body will result in demands for compensation from various actors, and a licensed fishing territory as an offshore wind farm installation site should be considered.

Hot water is used by having a wash, dishes, taking tub and drinking water in residential buildings, and the use objective is to raise comfort of human body sense, washing and sterilization effect and so on. Cold & hot water supply system is understanded simpler than HVAC systems relatively, so it is true that pace of performance improvement is slower than other systems for plan and technical development. In this study, the performance evaluations are conducted under the condition of composition ratio by 1:1 for cold & hot water supply manifold system using functionally complex valves such as constant flow regulating valve and 3-way mixing valve in the area of $105.6m^2$ apartment which consist of the largest part of the whole apartment. Also, flow rate related to simultaneous use of faucets and change of hot water temperature are compared with the existing method.

In order to secure the variability of long-life housing, dry walls are used. The composite gypsum board panel is the most frequently used infill system for the wall, and it is an excellent construction method in terms of constructability and economic feasibility. However, there are also problems such as the destruction of Ondol pipes at the bottom floor and being unable to fix the light weight steel frame (M-bar) when a variable composite gypsum board panel is used. To solve such problems, a wall with a method of fixing only the top part without fixing the bottom floor is developed, but it is difficult to identify the durability of ceiling frame according to the tensile force of stud and the safety according to the Stiffness and impact resistance (soft body) of ceiling frame. Therefore, this study verified the effectiveness of infill system for the wall by conducting experiment on the stiffness and impact resistance of composite gypsum board panel according to the reinforcement of ceiling frame (wooden frame, double saw-toothed bracket, Cross M-bar). As a result, it was possible to secure the safety of wooden frame while the impact resistance and the Stiffness of double saw-toothed bracket and cross M-bar were not secured.

The very definitions of posture and balance have changed, as has our understanding of the underlying neural mechanisms, In rehabilitation science, there awe at least two different conceptual theories to describe the neural control of posture and balance : the reflex/hierarchical theory and system theory. A reflex/hierarchical theory suggests the posture and balance result from hierarchically organized reflex responses triggered by independent sensory systems. The systems approach suggests that action emerges from an interaction of the individual with the task and environment. That is to say, the systems approach implies that the ability to control our body's position in space emerges from a complex interaction of musculoskeletal and neural systems, collectively referred to as the postural control system. The specific organization of postural systems determined both by the functional task and the environment in which it is being performed, The postural control system is divided into three basic functional components for assessment : 1) musculoskeletal components, 2) motor coordination components, and 3) sensory organization components. It is proposed that a systemic functional understanding of human balance is critical to effective programs for balance rehabilitation. Thus, this article briefly reviews the basic functional components to consider in designing treatment plan and for the benefit of the balance assessment.

The purpose of this study is to clarify the mechanical behavior of human lumbar vertebrae (L3/L4) with and without fusion bone under physiological axial compression. The author has developed the program code to build the patient specific three-dimensional geometric model from the computed tomography (CT) images. The developed three-dimensional model provides the necessary information to the physicians and surgeons to visually interact with the model and if needed, plan the way of surgery in advance. The processed data of the model is versatile and compatible with the commercial computer aided design (CAD), finite element analysis (FEA) software and rapid prototyping technology. The actual physical model is manufactured using rapid prototyping technique to confirm the executable competence of the processed data from the developed program code. The patient specific model of L3/L4 vertebrae is analyzed under compressive loading condition by the FEA approach. By varying the spacer position and fusion bone with and without pedicle instrumentation, simulations were carried out to find the increasing axial stiffness so as to ensure the success of fusion technique. The finding was helpful in positioning the fusion bone graft and to predict the mechanical stress and deformation of body organ indicating the critical section.

Anaplastic carcinoma of thyroid gland account for no more than 10% of thyroid cancer, but it shows extremely poor prognosis. The purpose of this study is to review the outcome of patients with anaplastic carcinoma over the span of 5 years and to determine the patterns of clinical presentation, age, sex and other possible prognostic variables. We analyzed 30 cases of anaplastic carcinoma retrospectively from 1991 to 1995. There were 14 men and 16 women. There age ranged 33 to 75 years with a mean of 61.0 years. Sixteen patients presented with transformationqr of well differentiated carcinoma to anaplastic carcinoma, 1 with rapid in-crease in the size of long standing goiter, 8 with rapidly growing neck mass and 4 with meta static disease. Twenty-eight patients(93.3%) showed cervical lymphnode metastasis at presentation and twenty three patients(76.6%) showed laryngotracheal invasion. Nine patients (30.3%) showed distant metastasis. Treatment modalities included surgical resection, external irradiation, radioactive iodine and systemic chemotherapy. At decision making of treatment plan, we considered completeness of initial surgery, uptake rate of whole body radioactive io-dine scan, locoregional progression and distant metastasis. The median survival was 6.8 months and three cases survived beyond 12 months.

Since IMF relief financing, domestic economy has been rapidly cooled down. At this point that we predict an overall decrease of production and sale of industries, cooperative marketing activities of the whole dairy industry are required to promote milk consumption. As everyone knows, advertisement is only one of the various factors that affect sales. Other factors include price, distribution, package, promotion, and consumer's needs and taste. The objectives of the cooperative advertising campaign should be trial purchase of new consumers, maintenance of brand loyalty of existing consumers, more positive experience of using the product, and increase of frequency of purchase. Long term analysis is essential to making these kinds of behaviour changes. Also the objectives of the communication program should be a shift of awareness of milk from 'a basic health food for children' to a substitute to the beverage even for adults. To share database of consumers among companies, we need to find ways to use interactive on-line services, the internet, D.M. events and so on as well as the mass media. It should be a precondition that the main body of the cooperative advertisement includes the milk processing board, dairy companies, livestock cooperations, farmers and the Government. To assure continuous, activities to promote milk consumption, the Government should take the lead in legislating 'An enforcement ordinance for milk promotion and research', and seek complementary measures and support to establish the ordinance.

Objective: The aim of this study is to investigate the effect of workload on musculoskeletal degeneration. Background: It is important that workers maintain a health body for a long time as a measure of aging workers. In order do so, it is necessary to find out if workload can effect on musculoskeletal degeneration. Method: Epidemiological studies on workload or occupation and disc degeneration, osteoarthritis of knee were identified through database and bibliography searches. Results: Epidemiological studies showed that workload certainly effect on musculoskeletal degeneration. But we couldn't know which of individual factors and occupational factors further contribute to the musculoskeletal degeneration. And we could find that studies on workload and genetic factors were very few. In addition, there was also very few studies that it was possible interaction between individual factors as obesity and occupational factors as heavy manual lifting. Conclusion: Our reviews suggest that it need to conduct study between workload and genetic factors for musculoskeletal degeneration. This further study can identify attributable risk of workload for musculoskeletal degeneration, and contribute to the measure of aging workers. Application: This paper can help to establish research plan for the measure of aging workers.

The first Pagoda of Korea was introduced from China, and adapted from the wooden multi-storied pavilion. Also in Bronze one, multi-storied type of wooden pagoda was adapted. Bronze pagoda was used to buddhist ossuary and a kind of metalwork. Metalworks were made of gold, silver, copper, or iron by one of the methods of production-casting or hammering and decorated design of incision, raise, openwork, gold- plating or inlaying with gold and silver. Sometimes it was used as the easy carriage of Buddha image by guess. In most cases, the plan of Bronze pagoda was square and podium was one story. but in the advance of podium two-storied platform appeared. Column appeared in a symbol, so it didn't appear in a square and circular form. It means that the column was vertical member which only divided the wall. In koryo period, Gabled roof and Half-hipped roof was spreaded in public but Bronze pagoda was used to square Hipped roof. Vertical shaft over roof(上輪部), apart from body of pagoda(塔身部), was inserted on the hole above the Bokbal(覆鉢) for the balance of pagoda. And a thick iron bar put in the roof to the platform. It was sustained the balance of pagoda. The stories of pagoda were various from 3rd stories to 9, the lower stories was larger scale and the higher was smaller one.

Although papillary carcinoma of the thyroid generally follows an indolent course characterized by slow growth and the absence of distant metastases, several available reports suggest that metastasis to bone and/or lung parenchyma may occur infrequently. But pleural metastases are known to be very rare, so there have been only two case reports about the pleural metastases of papillary thyroid carcinoma in the literatures. Even the case of occult papillary thyroid carcinoma presenting as a metastatic pleural effusion has been never been reported. Recently we experienced a case with the chief complaint of dyspnea due to massive pleural effusion, the cytologic examination of which revealed the papillary carcinoma with psamomma bodies. The examination of the thyroid revealed no definite primary tumor. The total thyroidectomy was done with the plan of post-operative radioactive iodine treatment and the pathologic result confirmed the occult papillary microcarcinoma as expected. With the present case report, the extension of the clinical spectrum. of metastatic papillary carcinoma of the thyroid is expected.
