In this study, the characteristics of digital anthropometric methods were determined with case studies. These methods were broadly classified into two categories: non-wearable and wearable. Then, these categories were further classified into four types: 3D Scanning, mobile app, smart clothing, and smart tool Among the non-wearable types, the "3D scanning" technique was based on the use of 3D hardware equipment. With this technique, the body shape was measured and the internal body information was obtained. Therefore, it is used in fields of healthcare and fitness. Among the wearable types, "Smart clothing" involves a special clothing that measures human body and a smartphone application. Both the components are linked to a fashion platform, which is based on the measured sizes that help shoppers. The "Smart tool" has the characteristic of measuring only with smart tools and smartphone applications; it does not involve the measurement of images. The common advantage of digital anthropometric methods are as follows: they reduce the time and cost of measurement by enabling self-measurement. Moreover, simple measurements are used to determine the size of anthropometry. Thereafter, it accumulates this data to track the continuous changes in size. From an industrial point of view, digital anthropometric technology should be used to increase sales. The on-demand market can be expanded as global consumers would throng the Korean fashion market. For the consumer, an avatar should be created to fit the user's size. This would provide a fun experience to the user.

With the mobile traffic in the network increases exponentially, multi-access edge computing (MEC) develops rapidly. MEC servers are deployed geo-distribution, which serve many mobile terminals locally to improve users' QoE (Quality of Experience). When the cache space of a MEC server is full, how to replace the cached videos is an important problem. The problem is also called the cache replacement problem, which becomes more complex due to the dynamic video popularity and the varied video sizes. Therefore, we proposed a new cache replacement scheme based on local video popularity and video size to solve the cache replacement problem of MEC servers. First, we built a local video popularity model, which is composed of a popularity rise model and a popularity attenuation model. Furthermore, the popularity attenuation model incorporates a frequency-dependent attenuation model and a frequency-independent attenuation model. Second, we formulated a utility based on local video popularity and video size. Moreover, the weights of local video popularity and video size were quantitatively analyzed by using the information entropy. Finally, we conducted extensive simulation experiments based on the proposed scheme and some compared schemes. The simulation results showed that our proposed scheme performs better than the compared schemes in terms of hit rate, average delay, and server load under different network configurations.

The purpose of this study was to analyze the three-dimensional hand-related dimensions of elderly women aged 70 to 84 years and to characterize them to develop safety gloves for dementia patients. The 3D data from the 8th Human Size Survey of the National Institute of Standards and Technology, Size Korea, were analyzed using the SPSS 26.0 program. The straight thumb length was longer in elderly women aged 70-74 than in those aged 80-84. To analyze the hand type of elderly women, four factors were categorized: hand and finger horizontal factor, hand vertical factor, finger digit V thickness factor, and finger length factor. Elderly women's hand types were categorized as 'long hands and thin fingers', 'thick hands with long fingers', and 'short hands and thick little fingers'. Elderly women aged 70-74 years and 80-84 years were analyzed as having the most 'long hands and thin fingers' type, while older women aged 75-79 years were analyzed as having the most 'thick hands and long fingers' type. It is known that the fingers get thicker and the size of hands increase as age advances, but by the age 80, there is a change in the size of hands again. In future research, it would be worth expanding to other age groups to explore differences between age groups and to develop safety gloves for real-world dementia patients based on the hand types analyzed.

The purpose of this study is to investigate empirically the characteristics of financial structure by using 76 fisheries corporations in Korea, and to suggest implications of the empirical results for government's financial policy for fisheries corporations. For the empirical test, we choose the following factors as the explanatory variables of cross-sectional regression analysis:firm-size(SIZE), collateral value of assets(TFATA), business risk(BRISK), growth(GROWTH), effective tax(ET), profitability(PROFIT). Two different debt ratios are used as dependent variables. One is defined as the ratio of total debt to total assets and the other is as that of long-term debt to total asset in terms of book value. The sample consists of 76 fisheries firms and sample period is 14 years from 1982 till 1995. From the results of cross-sectional regression analysis, the adjusted R$^2$values were high, 16∼79% and the overall F values indicated to be statistically significant. The results of cross sectional regression analysis show that the characteristics of financial structure fur fisheries corporations are as follows ; (1) Firm-size and collateral value of assets are the major factors of financial structure for fisheries corporations. That is, the larger firm-size the higher is debt ratio. This means that financial institutions conventionally lend more collateral loans with fixed assets like land, building rather than management capacities or credits. (2) To be consistent with a pecking-order theory, the higher is profitability the lower is debt ratio in fisheries corporations. (3) Corporations with high effective tax rate have lower financial leverage. Although the empirical results are inconsistent with traditional static trade-off theory, we think it would be attributed to government's various tax shelterings for fisheries which are likely to reduce tax shield effect of interests.

Cement mortar was hydrothermal-synthesized with particle size of tailings using scheelite tailings deposited without proper treatment, and its physical properties were investigated. The mixing ratios of water-cement and sand-cement were fixed at 75 % and 400 %, respectively, during preparing cemnt mortar, and the sand was replaced by the tailings at 0 ~ 50 %. The particle size of tailings was controlled at 9.3 ~ 53.0 ℃, and the hydrothermal temperature was kept at 60 ~ 180 ℃ for 6 hours after the temperature increased to pretermined temperature with 2 ℃ heating rate. The compressive strength increased with increasing hydrothermal temperature. The compressive strengths were 55.2 MPa and 54.5 MPa when the mortars were prepared with 30 % low arsenic and high arsenic tailings after 60 min grinding. The compresiive strenght was enhanced 300 % compared with reference sample.

Many research works have been done in the field of the relationship between regulations and business activities. In general, the relationship is negative, so government took a regulation relaxation policy for some period. However, recently, the better regulation concept is more emphasized than the regulation relaxation. In particular, as the new industry comes to appear, we need to analyze the effect of regulations in the new industry to the business activities, and set up the regulation advancement policy. In this paper, the effect of regulations in the new industry on business activities and performance was analyzed and implications for better regulation policy was derived. According to the results, the effect was different according to the firm's size and the degree of integration in R&D. Therefore we need some consideration of the firm's size and the degree of integration in R&D for establishing the regulatory policies.

A number of companies tries to transform into e-business organizations in order to enhance their productivity dramatically and create a new value for their customers. Even thought IT invenstment is essential to be an e-business company, it costs a great deal for mid-sized or small-sized companies. Thus, this study suggests a cost-saving and web-based IT outsourcing, application service provider (ASP) that is an applicable model to transform a traditional company into an e-business company. Although companies under mid-size are considering the ASP method when introducing ERP system, ASP is not widespread yet. Therefore, this study analyzes the actual cases of domestic firms which successfully implemented ASP-ERP and investigates the pros and cons of ASP method.

The study aims to identify factors that influence university and college students' entrepreneurial intentions in Vietnam's Mekong Delta region. The study examines entrepreneurship mindset, subjective norm, capital sources, concept development assistance, personality qualities, and perceived behavioral control of university support for a student's entrepreneurial aim. The research was conducted according to the quantitative method. The data was collected through an online survey with a sample size of 611 students from 19 universities and colleges in the Mekong Delta region. The methods that test the scale, including Cronbach Alpha Test, Structural Equation Modeling (SEM), are used to consider the correlation between the influence factors. The results of SEM analysis show that there are five main factors affecting students' entrepreneurial intention with decreasing level of influence, including the source of capital, perceived behavioral control, business development support, entrepreneurial attitude, and educational support. Besides, the results indicate that the subjective norm, personality traits, and concept development support have no impact on the intention of students toward entrepreneurship. The research also reveals that the entrepreneurial intention of students at universities and colleges has a positive relationship and is significantly affected by capital source and perceived behavioral control.

The purpose of this study is to survey toddlers' apparel brands in Korea for operation of pattern work rooms, pattern sizes and uses of bodies and measurements, and thereby, provide for some basic data useful to development of toddlers' apparel prototypes and production of bodies. For this study, 13 domestic brands were surveyed. The results of this study can be summarized as follows; As a result of surveying the pattern work rooms, it was found that 53.8% of the sample brands employed a director of pattern work room, while 38.5% of them did not employed any pattern director. 7.7% of the sample brands employed two pattern directors. Such findings suggests that pattern works for toddlers' apparels are neither specialized nor differentiated as for adults' apparels, and therefore, that apparel production is not efficient. In view of the body profiles, only six brands possessed some or other bodies produced in Japan. The average breast size of No. 3 body was found 51.7cm, waist 48.4cm and hip size was 53.7cm. According to National Standard Body Size Survey Report, average breast size of three-year-old toddlers is 51.2cm, The average waist size is 49.5cm, and the hip size is 52.6cm. All in all, our toddlers' sizes are slightly different from Japanese toddlers', and so, it is deemed necessary to produce the bodies for our toddlers' apparels. As a consequence of surveying the measurements used for pattern production, it was found that five brands of the sample brands were using some or other 'body measurements', and another five brands were body measurements and apparel ones in parallel. All the brands sampled were found using some or other 'apparel measurements'.
