This study considered regional differences in the university-industry collaboration of Korean universities and performed cluster analysis to identify the spatial range with high university-industry collaboration connectivity. By university establishment type, it was found that the university-industry collaboration capacity of the major national university was superior overall, especially in the technology transfer & commercialization sector and the infrastructure sector, compared to private universities and general national universities. The spatial pattern of university-industry collaboration capacity showed relatively clear differences by city and province. In terms of university-industry collaboration capacity by sector, it was confirmed that the regional gap was not large in the talent training sector and the infrastructure sector, but the regional gap was relatively large in the technology transfer & commercialization sector and the start-up sector. As a result of the cluster analysis to identify a spatial range with high connectivity in terms of similarity and spatial proximity of university-industry collaboration patterns, it is divided into 15 clusters. It is found that most of major national universities are included in one of 15 clusters where all sectors of university-industry collaboration are strong. Therefore, as a policy measure to achieve regional innovative growth through enhancing the effectiveness of university-industry collaboration, we propose the establishment of a hub & spoke network-type collaboration system in which a major national university acts as a hub and nearby local universities play a spoke role.

Recently, as ESG management has become an important issue, major companies in the automotive parts manufacturing industry are conducting ESG evaluations of their suppliers for the purpose of supply chain management. The results of these evaluations are being incorporated into contractual agreements. However, many small and medium-sized enterprises(SMEs) are lacking in their capacity and resources to effectively respond to ESG evaluations. Furthermore, existing ESG management guidelines do not provide an industry-specific guidance, making it necessary to establish industry-specific guidelines that SMEs can refer to. Therefore, in this study, the evaluation Indicators of ESG supply chain assessments are surveyed, which is conducted by domestic major automotive parts companies and global automobile manufacturers. Then 56 supply chain ESG evaluation Indicators are derived. Also, ESG management indicators for SMEs is analyzed through the Importance-Performance Analysis(IPA), based on an interview of expert groups. Therefore, this study could propose industry-specific ESG guidelines, based on the results of the derived indicators, which reflects the need for SMEs to practice ESG management within certain boundaries.

Livers of skipjack tuna (Katsuwonus pelamis) and yellowfin tuna (Thunnus albacares) were investigated on the food compositional characteristics and also compared to that of Alaska pollack (Theragra chalcogramma). The proximate compositions of skipjack tuna and yellowfin tuna livers were high in crude protein, carbohydrate, and crude ash, while were low in crude lipid when compared to that of Alaska pollack liver. The results of heavy metal suggested that tuna livers appeared safe as a food resource. The total amino acid contents of skipjack tuna and yellowfin tuna livers were 17.7 and 17.1 g/100 g, respectively, and the major amino acids in both livers were aspartic acid, glutamic acid, alanine, valine, leucine, and lysine. Tuna livers were good sources of iron and zinc, while have low lipid content. The extractive nitrogen contents of skipjack tuna and yellowfin tuna livers were 526.5 and 468.2 mg/100 g, respectively, and their major free amino acids were taurine, glutamic acid, and alanine. From the results of taste value, the major taste active compounds among free amino acids were glutamic acid and aspartic acid.

China is the largest producer and consumer of mushrooms, and the development of China's mushroom industry poses a serious threat to Korea, which has similar mushroom production and consumption tendencies. China's mushroom industry produced only 50,000 tons around 1985 when statistical data began to be published, but by 2020, it has developed into an industry with annual production exceeding 40 million tons. The rapid development of the mushroom industry in China is due to high profitability, rapid funds turnover, rapid return on investment, active support from local governments, increased preference and consumption of healthy foods due to increased national income, expansion of overseas exports, and introduction of automated facility cultivation. Recently, there is a high possibility that mushroom production through automated facility cultivation in China will be excessive, so if measures are not taken, there is a high possibility that it will encroach on the Korean mushroom market. Therefore, in order to protect domestic mushroom farmers and industries, it is necessary to accurately identify and analyze the current status of China's mushroom industry.

The occupational health problems are the major issue in the modern industrial society. Especially the small scale industries have many hazardous factors and not any occupational health programs in itself. Fortunately. the government-funded subsidiary program was developed and carried out in the past six years in our country. The purposes of this study were to find out the actual condition of the occupational health personnel's accomplishments for the government-funded subsidiary program for small scale industries and to provide basic data for setting up more developed subsidiary occupational health program. Data were collected through 6 kinds of service records review. These service records were written by 3 occupational health personnels were attached to the one subject center of KIHA. were undertaken during March to December, 1997. at 95 small scale industries which were applied the government-funded subsidiary occupational health program. Results were as follows 1. Concerning 95 small scale industries showed characteristics of a typical small scale industry. 2. A doctor visited in industries total 190 times per year, average 19 industries per month, twice per year and industry. A hygienist visited in industries total 378 times per year, average 38 industries per month, four times per year and industry. A nurse visited in industries total 477 times per year. average 47 industries per month, 5 times per year and industry. 3. 3 occupational health personnels accomplished total 3,869 items. A doctor accomplished total 539 items per year, each time 3 items In an industry. A hygienist accomplished total 1.581 items per year, each time 4 items in an industry. A nurse accomplished total 1.749 items per year, each time 4 items in an industry. 4. The major contents of doctor's accomplishment were 'health consultation for suspicious worker with general & occupational disease', 'a check of the workplace & special health education', 'guidance of special medical examination in the second half of year', etc. The major contents of hygienist's accomplishment were 'pretest & guidance of planning for evaluation of working environment'. 'evaluation for ventilating facilities & suporting self inspection', 'guidance of MSDS recording & chemicals management', etc. The major contents of nurse's accamplishment were 'health counseling of general & special medical examination results'. 'health education of preventing occupational disease & health disorder'. 'guidance of subsidiary program planning', 'selecting & guidance of health monitor', etc. It was concluded that the occupaional health personnels implemented the subsidiary program according to the order of health management guide. The current health management guide of subsidiary occupational health program in which the fixed contents, visiting number & periods is not desirable. That guide is left the characteristics of small scale industries out of consideration. It is suggested that occupational health management guide should be developed according to the general & environmental characteristics of each small scale industry, and on the other hand, the more specific guide for each occupational health personnel should be developed.

We attempted to define the sources of sodium intake for the Korean population at prepared dish level to provide a basis for developing sustainable nutrition policies and feasible programs for sodium intake reduction. Dietary intake data from 2008 and 2009 Korea National Health and Nutrition Examination Survey was used in the analysis for sodium intake sources. Sodium intake from individual dish consumed by each subject was calculated and used in delineating major sodium sources at dish and dish group level for sub-populations of different sex and age. Also, sodium intake was compared between eaters and non-eaters of some specific dish groups with considerable contribution to total sodium intake. The number of subjects included in the analysis was 18,022 and mean sodium intake was 4,600 mg/capita/day. Major sources of sodium intake at dish group level were in the following order: kimchi (1125 mg, 24.5%), noodles (572 mg, 12.4%), soups (488 mg, 10.6%), stews (399 mg, 8.7%), and cooked rice (284 mg, 6.2%). The magnitude of contribution to total sodium intake by soups and stews was different by age group. Sodium intake difference between eaters and non-eaters was much larger for kimchi group (2,343 mg for male, 1,452 mg for female) than for soups or stews. Interaction between consumption of aforementioned specific dish groups and age was highly significant (p < 0.0005) for both sexes. This study revealed an importance of having not only the control over sodium content of foods/dishes, but also the customized approach for different groups of population to accomplish an appreciable reduction in sodium intake.

Oil and steel prices, which are major pricescosts in the shipbuilding industry, were predicted. Firstly, the error of the moving average line (N=3-5) was examined, and in all three error analyses, the moving average line (N=3) was small. Secondly, in the linear prediction of data through existing theory, oil prices rise slightly, and steel prices rise sharply, but in reality, linear prediction using existing data was not satisfactory. Thirdly, we identified the limitations of linear prediction methods and confirmed that oil and steel price prediction was somewhat similar to actual moving average line prediction methods. Due to the high volatility of major price flows, large errors were inevitable in the forecast section. Through the time series analysis method at the end of this paper, we were able to achieve not bad results in all analysis items relative to artificial intelligence (Prophet). Predictive data through predictive analysis using eight predictive models are expected to serve as a good research foundation for developing unique tools or establishing evaluation systems in the future. This study compares the basic settings of artificial intelligence programs with the results of core price prediction in the shipbuilding industry through time series prediction theory, and further studies the various hyper-parameters and event effects of Prophet in the future, leaving room for improvement of predictability.
