  • This study aims to estimate optimal harvests, fishing efforts, and stock levels of hairtail harvested by the large pair bottom trawl, the large otter trawl, the large purse seine, the offshore long line, and the offshore angling fisheries by using the surplus production models and the current value Hamiltonian method. Processes of this study are as follows. First of all, this study estimates the standardized fishing efforts regarding the harvesting of the hairtail by the above five fishing gears based on the general linear model developed by Gavaris. Secondly, this study estimates environmental carrying capacity (k), intrinsic growth rate (r), and catchability coefficient (q) by applying the Clarke Yoshimoto Pooley (CY&P) model among various surplus production models. Thirdly, this study estimates the optimal harvests, fishing efforts, and stock levels regarding the hairtail by the current value Hamiltonian method, including the average landing price, the average unit cost, and the social discount rate. Finally, this study attempts a sensitivity analysis to figure out changes in optimal harvests, fishing efforts, and stock levels due to changes in the average landing price and the average unit cost. As results induced by the current value Hamiltonian method, the optimal harvests, fishing efforts, and stock levels regarding the hairtail caught by several fishing gears were estimated as 33,133 tons, 901,080 horse power, and 79,877 tons, respectively. In addition, from the results of the sensitivity analysis, first of all, if the average landing price of the hairtail constantly increases, the optimal harvests of it increase at a decreasing rate, and then harvests finally slightly decrease as a result of decreases in stock levels. Secondly, if the average unit cost of fishing efforts continuously increases, the optimal fishing efforts decreases, but optimal stock levels increase. Optimal harvests start climbing and then decrease continuously due to increases in the average unit cost. In summary, this study suggests that the optimal harvests (33,133 tons) were larger than actual harvests (25,133 tons), but the optimal fishing efforts (901,080 horse power) were much less than estimated standardized fishing efforts (1,277,284 horse power), corresponding to the average of the recent three years (2014-2016). This result implies that the hairtail has been inefficiently harvested and recently overfished due to excessive fishing efforts. Efficient management and conservation policies on stock levels need to be urgently implemented. Some appropriate strategies would be to include the hairtail in the Korean TAC species or to extend the closed fishing season for this species.

  • This study empirically analyzed the effect of outdoor brand consumer's consumption value and company's creating shared values activity on consumers' purchase intention. The sub-variables of consumption value were set as functional value, conditional value, and emotional value as factors affecting consumers' purchase intention. The sub-variables of company's creating shared values activities were set as economic value, relational value, social value. As a result of analysis, functional value, conditional value, and emotional value of consumption value were found to have a positive effect on purchase intention, and economic value, social value, and relational value of company's creating shared values were all positively influenced Respectively. According to the results of the analysis, it is found that both consumption value of outdoor brand consumers and company's creating shared values activities are positive factors for purchase intention. This result can be deduced that consumers 'consumption value and company's creating shared values activities in outdoor brand industry are already reflected in consumers' purchase intention.

  • The purpose of this study was to examine how combined exercise and acaiberry intake make effects on insulin and glycated hemoglobin of middle-aged women. The middle-aged women in their 40s and 50s were classified into three groups - group A which only had acaiberry intake, group B which both had acaiberry intake and combined exercise, and group C which only underwent the combined exercise. The combined exercise was held three times a week for 8 weeks, each for 60 minutes including warming up and cooling down. The aerobic exercise was carried out for 20 minutes with a treadmill walk with HRmax 50-60% and the resistance movement was carried out for 20 minutes with a strength of 50-60% based on 1RM. The participants were told to have the acaiberry drink before breakfast and dinner, by melting 5g of acaiberry powder to water. 2-way RGRM ANOVA was carried out to process the data for comparing each groups. In conclusion, the 8-weeks of combined exercise and acaiberry ingestion therapy did not improve the insulin and glycated hemoglobin. It is more likely to show clear changes in both elements with longer treatments and controlling the amount of ingestion and exercise intensity.

  • Limit state design has been implemented in Korea since 2015; however, there exists no specification of lateral load determination on retaining wall due to the Korean standard traffic load on retaining wall's backfill surface. The lateral load from traffic depends on lane number, standard truck's axle loads and locations, loading distance from the inner wall. The concept of equivalent height of soil accounting for traffic loadings is typically used for design of retaining walls to quantify the traffic loads transmitted to the inner wall faces. Due to the different characteristics of the standard design trucks between Korea and US (AASHTO), the direct use of the guidelines from AASHTO LRFD leads to incorrect estimation of traffic load effects on retaining walls. This paper presents the results of evaluation of equivalent height of soil to reflect the Korean standard truck, based on the findings from analytical solutions using Bounessq's theory and numerical assessment using 2D finite element method. Consequently, it was found that the equivalent heights of soil from the Korean standard truck load were lower for lower retaining wall height.

  • This study is a phenomenological study attempted to examine adaptation of North Korean defectors to life in the South Korean society in a comprehensive and in-depth way. Data were collected from July 2016 to June 2017 by conducting interviews with 10 North Korean defectors about their experience in adaptation to life in the South Korean society. The collected data were analyzed by the Colaizzi method. The original data obtained from the participants were structured into 19 themes, 6 theme clusters and 4 category. The 4 category included 'to face the different world', 'lives as a stranger', 'to adapt something', 'to reach self-realization'. The 6 theme clusters included 'encounter with new world', 'psychological pain', 'obstacles of the reality', 'drifting in the South Korean society', 'becoming a member of South Korea' and 'an independent life'. Based on the results of this study, it would be necessary to conduct a repetitive study on the process of adaptation of North Korean defectors to life in the South Korean society, to develop an intervention program to help them adapt to the South Korean society, and to verify the effects of the developed program.

  • TV Broadcasting is an undeniable cultural medium. TV Broadcasting Station needs a long-term perspective that suits cultural media and an aggressive cultural and artistic program development strategy that matches rapidly changing culture and technology. Of course, production staff should be composed of experts in the field as well as cultural artists. This paper is researching the promotion strategy of TV Arts programs by substituting the three keywords - the U.S., the public broadcasting station(TV) and Arts programs. And through case studies and analyses of PBS TV's "Art in the 21st Century" series, the way the public TV broadcasting station shares cultural arts with viewers is extracted. It raises the question of how the U.S. TV public broadcaster's cultural and artistic programs are different from South KOREA's. Through the above research, let's find a clue to the future direction of how the new media, now represented as Korea's blacklist, should recognize, foster, educate and strategize Fine Arts.
