The purpose of this study is to create the program for efficient inventory management and reduction, investigating the present conditions and factors of the inventory throughout current apparel industry. The research method applied in this study is to survey 92 domestic companies which were randomly selected with respect to the kinds of goods produced : men′s wear, women′s wear, and unisex wear. The research can be summarized as follows : 1. The seasonal stock rate of current apparel industry was 28.75%, and the rate of men′s wear companies was higher than that of women′s and unisex wear companies. 19.43% of stock cost reflection rate was applied, and the stack cost of men′s and women′s wear companies was higher than that of unisex wear companies. 2. Periodic bargain sale was the most frequently used way of stock clearance, and "uniform price sale"and outlet stores were the second and the third irrespectively. Unisex wear companies appeared to be more enthusiastic in stock clearance than the companies belonging to the other two categories. The main places for the stock clearance were department stores, outlet stores and enterprises specialized in the stock clearance. 3. QR production was proved to be the most commonly adjusted method of stock reduction, and the emphasis on development of new design and the utilization of stock management system through computer network were the next, While unisex wear companies had established the positive policies, men′s wear companies took lukewarm altitudes in every aspect. The companies selling on an order were 18.64%, and unisex wear companies showed the higher rate. The lead-time after QR production was 10.91 days, and it seemed to take more time for men′s wear companies than for women′s and unisex wear companies. The rate of the chance in stock was proved to decrease by 12.94%, and there was found no meaningful difference among the three categories of apparel companies.

This paper analyzes the noise reduction of traction motor for rolling stock. Nowadays, rolling stock becomes a attractive transportation as a friendly environment transportation. And this paper showed that vibration noise of motor coil by inverter switching frequency. That noise has influence on passenger. It is important that noise reduction for passenger in the rolling stock. In this paper, it shows that effect of variable switching frequency of propulsion inverter for noise reduction.

Recently, the electronic circuit with microprocessor based control system instead of conventional analog circuit is widely used for rolling stock, and also these circuits are widely adopted for train control and monitoring in modem rapid transit system. Noise, distortion and attenuation are always present in electronic equipments and strictly limit performance. The purpose of this paper is to propose noise reduction technology for electronic equipments in rolling stock.

철도차량의 안전성을 확보하기위해서는 견인성능 및 속도의 변동성을 고려하여 감속기의 피로해석에 관한 연구를 수행하는 것이 중요하다. 본 논문은 고속철도차량 감속기 기어의 변동하중하에서 피로파괴에 대하여 준정적 유한요소해석과 선형 Miner's Rule에 의한 내구성해석을 수행하였다. 해석을 위한 변동하중이력은 열차견인성능곡선과 상업운전조건에서 운전선도를 기초로 MSC.ADAMS의 동역학 해석에 의하여 구축하였다. 또한 감속기 피로수명은 기어표면의 침탄부 효과를 고려한 유한요소모델을 사용하여 변형률-수명접근법에 의하여 예측하였다. 해석결과로부터 급출발에 의한 빈번한 높은 기동토크와 정차역수의 증가는 철도차량 감속기 기어수명을 감소시킴을 알 수 있었다.

Due to the improvement of modern information technologies, sharing stock information among the supply chain members is a common practice nowadays. Many companies are planning to adopt the information systems to possess the real-time shared stock information. Thus, it is needed to quantify the value of shared stock information. The purpose of this paper is to evaluate the value of the shared stock information for two-echelon distribution systems. Existing reorder policies can be classified into installation stock policies and echelon stock policies. Since installation stock policies do not utilize the shared stock information, and both classes of policies may show poor performances for distribution systems, we cannot evaluate the value of the shared stock information with the existing policies. Thus, we provide a new type of reorder policy, named order risk policy. We define the order risk using marginal analysis, and prove the optimality. Through computational experiment that compares the order risk policy with the existing policies, it is shown that a significant cost reduction is achieved with the effective utilization of the shared stock information. We also show the effect of the system characteristics on the value of the shared stock information.

The autoclave method and the traditional cooking method were compared for nutrients(especially, minerals), color difference, viscosity, reduction of sugar and amino nitrogen content of brown stock. The autoclave cooking method is better than the traditional cooking method for retaining protein and amino nitrogen contents, as well as for reducing sugar content. Also, reducing sugar content increased by the autoclave cooking method. Since the color of brown sauce was related with the reducing sugar content, the autoclave cooking method was more effective than the traditional cooking method for the color development of brown stock. Since the autoclave method can reduce the cooking time without a loss of quality in brown stock, the autoclave method is a viable alternative to the traditional method of preparing brown stock.

Purpose - This study seeks to summarize the tax changes in stock trading and analyze K-OTC stock trading data in 2017 and 2018 to infer the effects of the application of capital gains taxes by individual investors. Design/methodology/approach - This study analyzes the case of the expansion of the 2018 capital gains tax exemption in the K-OTC market, which exempts capital gains tax on the proceeds from the sale of individual investors of certain stocks under the temporary special law. Findings - In the K-OTC market, the amount of transactions has expanded since the capital gains tax exemption in 2018, but the volume of transactions and transaction turnover have decreased. In particular, the result of lower transaction turnover after the expansion is contrary to expectations. To control the macroscopic effects of the stock market, further analyses the transactions of capital gains tax-exempt stocks and non-exempt stocks. The turnover rate of exemption stocks is higher than that of the non-exempt stocks. In the case of transaction turnover, the two results are not consistent. However, the latter result is more meaningful because the comparison of exempt and non-exempt reduces distortion by macro effects. Research implications or Originality - To mitigate the impact of capital gains taxes on stock market, government authorities need to consider the gradual expansion of the scope of taxation, the application of separate taxation in the introduction of capital gains, the reduction tax rate on transfer income of listed shares, and the reduction tax rate on long-term holdings.

In this paper, a theoretical approach is studied to predict structural performances and weight reduction rates of a car-body with shell type sections in case that its materials have to be substituted. For the material substitution design of a car-body, bending, axial and twisting deformations are considered under constant stiffness and strength conditions, which utilize some new indices derived from a structural performance point of view. The developed indices to measure the weight reduction by the material substitution give good guidelines on conceptual design of car-bodies.

This research aims to examine and assess how management methods, financial conditions, and corporate governance strategies affect stock returns. This study employs a quantitative approach with a population of 1968 firms with stock returns (return) and a sample of 225 companies with corporate governance practices in the manufacturing industry in Indonesia from 2013 to 2018. The findings of this study show that strategic management has a significant impact on stock return, financial condition, and corporate governance strategy. The findings of this study on debt strategy as a proxy for management strategy, debt default as a proxy for economic conditions, corporate governance strategy as a proxy for centralized ownership, and independent commissioners function as a mechanism of internal and external control in increasing stock return for investors all support increasing stock return for investors. The cost reduction strategy includes reducing operating costs unless the audit committee has not yet functioned as an internal control or requirement for a company to be listed with the Financial Services Authority on the Indonesia Stock Exchange.
