Variety of companies which carry out R&D projects supported by government are proposing quantitative evaluation index business plans. However, Many companies have difficulties in aspects of selecting quantitative evaluation index and in some cases they have troubles to get results from selecting unsuitable evaluation index. First of all, both methods of gathering the data to be analyzed and the products which are tested by the accredited testing institutes classifying by industrial sectors are classified as the quantitative evaluation index selected by the company according to the eight quality characteristics of ISO/IEC 25023 Standard. Secondly, based on the results of the quantitative evaluation indexes classified into eight quality characteristics of the ISO/IEC 25023 standard, the tendency of the quality characteristics of the quantitative evaluation indexes selected mainly by the companies will be understandable. It is hopefully expected that this research will be helpful to select a quantitative evaluation index to evaluate the quality of software products.

This paper analyzed the effects the regional competitiveness index on the characteristics of the regional growth. This study divides the regions in the US based on the static and dynamic standard of income for the characteristics of the regional growth. The results of the analysis are as follows. First some regions such as Alaska, Connecticut, Maryland, Massachusetts, Virginia, Washington and Wyoming have higher levels of SCI and both the rate of growth and per capita income than the national average. These are considered prosperous regions based on their high level of SCI. Second, in regards to the relation between the income level and regional competitiveness index for the regional growth, the variables such as human resource, science technology, business incubation, openness, safety and environmental policy are significant. Third, infrastructure, human resource, science technology and openness are the significant variables concerning the relation between the rate of income growth and regional competitiveness index for the regional growth.

The abalone aquaculture has been very rapidly developed in Korea. Annual production quantity was less 200 tons before 2000th, it have been increased to over 9,000 tons in 2014. Also Abalone export amounts have been over 20 million dollars. The reason of rapid growth of Abalone aquaculture in Korea is due to high level profit ratio. Then now many fishing officers and other aquaculture fishers want to participate with abalone aquaculture newly. However Recent Abalone aquaculture in Korea is faced some problems. Aspects of production environmental status of fishing grounds are more aggravate, and then abalone aquaculture is exposed to various disease, and death rate of young abalone is higher. And aspect of management, the aquaculture cost is more increase. The demand of abalone also is depressing recently, this cause to come down the production price. In this viewpoint, Management analysis of abalone aquaculture in Korea is helpful for decision making of general aquaculture fisher want to participate newly. The analysis is practiced two aspects. One is index analysis, and the other is Break-even-point(BEP) analysis. The result of index analysis, average net profit rate has shown 28.0%, however the Regional difference has excessive. That is, Wando(major) has shown 39.4%, and Haenam province has shown 14.2%. On the other hand, the more scale has shown higher profit rate by aquaculture scale. And the result of BEP analysis, average has shown 93 cage number per abalone aquaculture household, and Wando(major) has shown 56 cage number, Haenam province has shown 131 cage number. The lower production abalone price of recent means higher BEP level.

In this study, we analyzed national mining investment security and country risk, and suggested a new index for exploration and development investment for mining projects in abroad by an analysis of relationship between these grades and mineral resource development investment. For this, potential risks for mining in mineral-rich countries are assessed, and the risk of the exploration and development investment for mining projects is relatively evaluated by OECD country risk. It is noted that countries of the lower ranks in OECD are consistently good agreement with the high grade in Behre Dolbear Group Inc. for favorable mineral exploitation, whereas the higher ranks have shown diverse and high risks for the mining investigation and development. Consequently, it is necessary that assessment of the relationship between mineral resource index and country risk for mining projects to be investigated and developed in future should be applied before business decision of mineral investigation projects in abroad.

It is general that the impact of supply chain risk spread out to the whole network along the connected structure. Due to the risk propagation the probability to exposure a certain risk is affected by not only the characteristics of each risk factor but also network structure. It means that the structural connectivity among vertices should be considered while designing supply chain network in order to minimize disruption cost. In this research, the betweenness centrality has been utilized to quantitatively assess the structural vulnerability. The betweenness centrality is interpreted as the index which can express both the probability of risk occurrence and propagation of risk impact. With the structural vulnerability index, it is possible to compare the stability of each alternative supply chain structure and choose the better one.

The administration of a regional public hospitals are expending from profit preference to publicity preference. The weight rate for a profitability and publicity of performance assessment has changed from 84:16 which was resulted by the assessment executed firstly in 1989 to 39:61 as resulted in 2004, the final assessment execution in 2005. Regional public hospitals are exerting and promoting a magnification in public sector to raise up the public-score. With comparison between publicity scores and profitability scores in original scores basis excluding weight rate, the publicity scores ranked higher than profitability scores although the latter was higher by 2002. However, for the administration performance of the regional public hospitals, the deficits increased 11 times from \92.6billion deficits with \460.3billion cost increased by 457% although income as \367.7billion increased by 394% comparing the last 2004 year to the first 1989 year for profit & loss statement of a regional public hospitals. There was analysis for the relation in yearly basis partitioning publicity and profitability for the assessment scores of the to regional public hospitals confirm the accumulated deficits of the hospitals like this attribute to the extension of public sector. The result showed that there was distinct plus relationship from 1999 although a minus relationship in general until 1997 except 1992 and there is a more plus relationship as approaching 2004. That is, it is hard to tell that the accumulated deficits increase of regional government medical center attributed to extension of public sector. On the contrary, the analysis showed the extension of public sector has a mutual relationship with uplift of profitability Meanwhile, it showed that operation cost rate and labor cost are the factors which influence a revenue & expenditure rate among the profitability index according to the results of relation analysis for the representative index of profitability and that of publicity.

Although the CM(construction management) market in Korea has shown rapid growth, unlike other market sectors, there has been lack of a system by which the economy trend of the CM market can be analyzed. The objective of the paper is to analyse and identify key characteristics of the CM market as of the third quarter of 2010 by using the CMBSI(Construction Management Business Survey Index) which was proposed in the previous study. In the paper, the CMBSI is used as the main index along with other five supplementary indices. The use of the CMBSI can contribute to enhancing the understanding of CM market situation and prospect, and also to providing information for CM policy and regulations.

This paper aims to investigate if a total of 266 college students from Yanbian, China, and Korea's Jeonnam Province are satisfied with their face and body type, and to find out an image-development method, depending on body characteristics. For this, a questionnaire survey using the 5-point Likert Scale was conducted, and an SPSS program has been used for data analysis. Besides the descriptive analysis, crosstab analysis, t-verification, and frequency analysis have been conducted. As body shape, posture, costume, accessories and makeup play an important role in image formation, this paper intends to form positive ego through exact awareness of the body shape by providing base data to a set image-development strategy. Then, the result has turned out as follows: First, in terms of the body index (i.e., Rohrer index), both Korea's Jeonnam Province and China's Yanbian college students were included in a category of the mean value. In terms of satisfaction with their body shape, on the contrary, China's China's Yanbian college students were higher than Korea's Jeonnam Province college students. Second, male China's Yanbian college students were slightly higher than female China's Yanbian college students in terms of satisfaction with their facial shape. However, the male students showed no big interest in facial care. Third, in terms of facial shape, an egg-shaped face was the most preferred in both China's Yanbian and Korea's Jeonnam Province college students, followed by an inverted triangle-shaped face in China's Yanbian college students and a diamond-shaped face in Korea's Jeonnam Province college students, showing significant difference ($p{\le}.001$). Even though both college students live in Northeast Asia, their preference on facial shape turned out to greatly differ, which indicates their different social environments. This paper will be helpful in global marketing for college students who are the major consumers in the future as Korean-Chinese exchange increases.

Purpose: The purpose of this study is to overcome limitations of conventional studies that to predict Baltic Dry Index (BDI). The study proposed applications of Artificial Neural Network (ANN) named Long Short-Term Memory (LSTM) to predict BDI. Methods: The BDI time-series prediction was carried out through eight variables related to the dry bulk market. The prediction was conducted in two steps. First, identifying the goodness of fitness for the BDI time-series of specific ANN models and determining the network structures to be used in the next step. While using ANN's generalization capability, the structures determined in the previous steps were used in the empirical prediction step, and the sliding-window method was applied to make a daily (one-day ahead) prediction. Results: At the empirical prediction step, it was possible to predict variable y(BDI time series) at point of time t by 8 variables (related to the dry bulk market) of x at point of time (t-1). LSTM, known to be good at learning over a long period of time, showed the best performance with higher predictive accuracy compared to Multi-Layer Perceptron (MLP) and Recurrent Neural Network (RNN). Conclusion: Applying this study to real business would require long-term predictions by applying more detailed forecasting techniques. I hope that the research can provide a point of reference in the dry bulk market, and furthermore in the decision-making and investment in the future of the shipping business as a whole.
