This paper intends to propose the direction for improving the welfare space in crew accommodation of fishing vessels engaged in coastal and inshore fishery business in order to solve the phenomenon which young fishers trend to avoid working on fishing vessels. Coastal and inshore fisheries are defined as permitted fisheries business under the Fisheries Act and classified into coastal fisheries and inshore fisheries based on a gross tonnage of 10 tons. Fisheries Act also stipulates the upper limit tonnage regulation and the restrictions on bottoms of fishing vessels permitted for coastal and inshore fisheries to protect fishery resources and to prevent overfishing. It is difficult to increase the welfare space in crew accommodation of fishers under such restrictions because the welfare space in crew accommodation could be secured by reducing the space for the strength of fishing. Therefore, this paper compares the revision trend of the international convention(The Work in Fishing Convention, 2007) and domestic laws on welfare space in crew accommodation of fishing vessels engaged in coastal and inshore fishery business to find out the problems and improvement points in securing the welfare space in crew accommodation of fishing vessels. As a result, it is proposed to revise the Enforcement Ordinance of the Fisheries Act so as to secure the welfare space in crew accommodation of coastal and inshore fishing vessels within the scope of maintaining the maximum allowable tonnage limit regulation by adding an exemption provisions of the restrictions on bottoms of fishing vessels in which case the gross tonnage is increased for securing the spaces for crew accommodation and sanitary facilities of fishers without increasing net tonnage where the bottoms of fishing vessels is increased by renovating or replacing the fishing vessels bigger than the bottoms of fishing vessels permitted within the scope of maintaining the maximum allowable tonnage limit regulation.

Purpose: This study has developed economical and environmentally friendly storage type infiltration facilities that securing storage space inside the infiltration facility. It focused on preventing flooding rainfall as well as securing more groundwater through rainwater infiltration that is valuable for the dry season. In addition, this study compares the installation cost of the storage-type infiltration facility to the cost of the conventional rainwater management facilities to demonstrate the economic efficiency of the storage-based infiltration facility. Method: Unit infiltration of this facility is calculated and when it was applied to a certain capacity, the amount of countermeasures are proposed in case study. Result: Unit infiltration of it is $0.2541m^3/hr$ and un it Temporary storage of it is $1.054m^3/m$. As a result, the infiltration effect of this facility is $1.306m^3/hr$. The cost was approximately 30% reduction in time to apply the storage type infiltration facility as compared with the case to apply the existing penetration of the facilities. Since the penetration of the existing facilities is smaller than that and it has much securing volume to process the same the amount of countermeasures. Therefore, it is determined that the cost significantly increases in material cost part. On the other hand, storage type infiltration facility is installed a small quantity because Unit Temporary storage and infiltration are bigger than that. So, it occurred to reduce material and installation costs.

Problems in regard of ecological stability of urban ecosystem ensue from climate change and urbanization. Particularly, urban ecological conditions are deteriorating both quantitatively and qualitatively to a great extent. The present study aims to assess the current condition of selected sites (i. e. urban green zones and parks) in terms of preset assessment components; to find out problems and relevant solutions to improve the quality and quantity of parks and green zones; and ultimately to suggest some measures applicable to coping with climate change as well as to securing the ecological attributes of urban green zones and parks. According to the findings of this study, from quantitative perspectives, ecological attributes and responsiveness to climate change are high on account of the large natural-soil area(80%). By contrast, from qualitative perspectives including the planting structure (1 layer: 47%), the percentage of bush area(17%), the connectivity with surrounding green zones (independent types: 44%), the wind paths considered (5.6%), the tree species with high carbon absorption rates (20%), water cycles (17%), energy (8%) and carbon storage capacities(61%), ecological attributes and responsiveness to climate change were found very low. These findings suggest that the ecological values of urban parks and green zones should be improved in the future by conserving their original forms, securing natural-soil grounds and employing multi-layered planting structures and water bodies, and that responsiveness to climate change should be enhanced by planting tree species with high carbon storage capacities and obtaining detention ponds. In sum, robust efforts should be exerted in the initial planning stages, and sustained, to apply the methodology of green-zone development along with securing ecological attributes and responsiveness to climate change.

Research and conservation of plant species for the nation arboretum, collection and securing of the plant species for both public and private arboreta and education for the arboreta which is affiliated to the university are overall management goal of the arboreta in Korea. Most of the arboreta in Korea run the programs and events for guide and interpretation of forest, but the programs and events are not well specified by the arboreta. Regarding the reasonable level of entrance fee should be discussed further as the lack of information and understanding. But the specified entrance fee between public and private arboreta should be considered. An eighty three percent of arboreta in Korea has been properly managed the species information. The reasonable management should be considered in case of unusual management of collected plant genetic resources. Although the overall impending difficulties for the management of arboreta in Korea is the lack of trained or qualified staffs, securing tasks independently for the public arboreta and relatively low salary for the private arboreta are main difficulties. Most of the difficulties are derived from the lack of its mission of the arboreta. The management of arboreta by the mission statement is one of the core targets including the characters such as climate or region should be considered. The securing qualified or trained staffs should be considered in the development of arboreta in Korea including the modification of relevant regulations or law.

This study has been carried out to provide data for the workforce by analyzing personnel status of medical device manufacturers, level of difficulty in securing human resource, reason for difficulty in securing human resource, resignation rate, and recruitment methods. Results, medical device manufacturers are required overseas sales personnel responsible for international certification and exported, regardless of the production item. And the company is located in the metropolitan area did not facilitate a secure workforce. Medical device manufacturers have difficulties in securing personnel, regardless of the employees and sales. In particular, Class 3 production company was more difficult. The reason that it is difficult to secure the human resources is attributable to the poor working conditions of the private companies and there is a few possible employees equipped with the job competency demanded by corporate entities. With respect to the analysis on the retirement rate, the larger the company scale and the more the employee number, more difficulty is experienced in the human resource management. Therefore, for any medical device manufacturers with large organization scale, it would be critical to introduce appropriate human resource management program.

The pressure safety valve is very important device for securing the safety in the facilities which is operated by high pressure gases. The performance test should be periodically inspected by relate law because the failure of pressure safety valves might be main causes of serious accidents in the industrial fields. Shop test is mainly use for inspecting the performance test of pressure safety valves but the test method is not to be a solution for securing the safety. So, the development of alternative method is required. In this paper, there is a limit to securing the safety if the performance test is with just shop test. The limitation is checked from analysis result based on performance test results of pressure safety valves. The necessity for introducing the in-service test is reviewed to surmount the limitation. As a result, in-service test method should be developed and introduced to improve the inspection efficiency and economical loss. Also, it can be reduce the risk level.
