Recently, in the process of developing, verifying, and upgrading the e-Navigation service and autonomous navigation system, there is an increasing demand for inter-working with a ship-handling simulator that can simulate actual maritime traffic conditions. In this paper, to develop a ship-handling simulation system based on actual maritime traffic conditions, a simulation server was built, received information on the actual maritime traffic conditions from the e-Navigation linkage system, and changed to information for operating the ship-handling simulator. In order to provide simulation images to users, 3D shape modeling for trade ports, coastal ports in Korea and major type of ship were performed. The developed system will be used for the advancement of e-Navigation service, development and verification of autonomous navigation systems, by enabling simultaneous processing of more than 10,000 ships and allowing users to simulate actual maritime traffic conditions in the desired area.

The actual working time of jobs, in general, is different to the standard time of jobs. In this paper, in order to analyze the actual working time of each job in production, we use the total production amount and the encessary total working time. The method which analyzes the actual working time is as follows. In this paper, we propose the interval regression analysis for obtaining an interval linear regression model with constraint conditions with respect to interval parameters. The merits of this method are the following.1) it is easy to obtain an interval linear model by solving a LP problem to which the formulation of proposed regression analysis is reduced, 2) it is easy to add constraint conditions about interval parameters, which are a sort of expert knowledge. As an application, within a case which has given certain data, the actual working time of jobs and the number of workers in a future plan are estimated through the real data obtianed from the operation of processing line in a heavy industry company. It results from the proposed method that the actual working time and the number of workers can be estimated as intervals by the interval regression model.

Depending on the progress of the industrial advances, the use of the thermal oil system in the utility system has been increased, which became an important part in the operation of the plant. However, fire or explosion have occurred due to lack of risk awareness and safety management, more frequently than we know. In this study, by using a questionnaire, actual conditions of safety management in thermal oil system is surveyed and analyzed, it is composed of general, a safety status of the thermal oil system component and the stage of recognition and management in the thermal oil system. These results of this study can be used as basic data to the safety management and the accident prevention of fire or explosion in the workplace.

This study provides basic reference data for brassiere wearing conditions, design preferences of new silver women (50s-60s) and development of brassiere products. We compiled and compared 163 pieces of brassiere (considering of 105 domestic general brassieres and 58 foreign silver brassieres) analyzed using SPSS Statistics 21 program. A survey was then conducted on the actual wearing, purchasing conditions, design preferences for 176 females (50s-60s). The result of this study are as follows: First, comparing actual product conditions (domestic general products and foreign silver products), the ratio of full cup in cup height, V-shape type in neckline shape, long type in front-end length, wide type in wing width, U-shape type in shoulder strap form, wide type in shoulder strap width, no-wire brassieres in breast wire type, all-in-one type in shoulder strap separation, back type in closure type appeared higher than other types of brassiere in domestic general product. Second, a study also showed that 60s women's wearing time is lower than 50s women's; however, 60s women expressed a higher figure and preference for the purchasing ratio in the department store, full cup in cup height, short type in length of brassieres, wide type in wing width, U-shape in shoulder strap form, small type in shoulder strap width, back type in closure type and no-wire brassieres than those in their 50s. It was found they prefer fabric with a high natural content, nude tone color without decoration & pattern and camisole brassieres.

Purpose: In Japan, the Long-Term Care Insurance Act has stipulated visiting rehabilitation since 2000. This study aimed to identify the actual conditions of visiting rehabilitation in Japan through a literature review of reports published by the Japanese government. Methods: This literature review was conducted on eight articles among various government reports on the topic of the actual conditions of visiting rehabilitation. These reports were published by the Ministry of Health, Labor and Welfare of Japan based on their own investigations or reports from an external agency entrusted with the task, and were issued between 2000 and 2021. Results: The characteristics of the visiting rehabilitation offices, their number, manpower allocation, the number of users, and their visits to each office were identified. Also, the characteristics of the users, number of users, age and required degree of long-term care, causative disease, and required medical care were identified. To evaluate the actual status of the visiting rehabilitation service, the service use time, frequency, period of use, intervention by doctors and the degree of such intervention, therapist's service content, visitors' address before the use of the service, reason, and timing of the service introduction, evaluation of the service effectiveness, combination of services and transfer destination after termination, and status after service termination were checked. Conclusion: Based on the Japanese experience where visiting rehabilitation was introduced and applied to long-term care insurance, it would be meaningful to review the factors that required benchmarking among the Japanese service models while designing a similar model in Korea.

The purpose of this study was to provide basic reference data for the development of slim-fit dress shirts patterns for a variety of body somatotypes. For this study, a survey was conducted on the actual product conditions of slim-fit dress shirts of domestic brands(Actual wearing and purchasing conditions, fit, design preferences). The survey was conducted on 135 men in their 20s~30s. PASW Statistics 18 was used for data analysis. The result of this study are as follows : Analysis of the actual wearing conditions of dress shirts indicates that consumers own an average of 1~2 classic-fit shirts and 1~4 slim-fit shirts. These are normally worn once or twice a week, and purchased mainly at department stores, agencies, direct sales markets or outlets. With respect to the purchasing factors, price and style were the main priorities. Surveyed consumers had the greatest preference for designs with a non-darted front and a darted back, a semi-wide collar and the color white. By classifying the surveyed by somatotype, Type B preferred designs darted on both front and back, Type A preferred designs with a non-darted front and a darted back, while Type Y preferred designs non-darted on both front and back. All somatotypes displayed a preference for semi-wide collars and the color white.

This research has a purpose to examine the actual conditions of natural dyeing program as a personal learning experience, participants' characteristics and common people's interest on natural dyeing nowadays. To examine the actual conditions of natural dyeing center and programs, many web sites and newspapers dealing with natural dyeing were used as main resources. As common people's interest on natural dyeing increased, there were a lot of natural dyeing centers in around country. To examine the interest on natural dyeing and the participants' characteristics of natural dyeing program, the data was obtained from a convenient survey of 326 respondents over 15 years old during 15th, May~30th, July in 2006. Almost 40% of respondents were interested in natural dyeing, but only 19% of respondents had ever participated in natural dyeing experience program. The participants' characteristics such as motivation, participating time, dyeing sources and materials, etc. were examined. Almost 65% of respondents were satisfied with natural dyeing experience. As long as people have interest on natural dyeing, Industrialization of natural dyeing will be advanced.
