In the application of the ecosystem-based fisheries assessment Jeonnam marine ranching ecosystem, two fisheries, funnel fishery and trap fishery, were selected as target fisheries. Black seabream, Acanthopagru schlegelii, rock bream, Sebastes inermis, gray mullet, Mugil cephalus, were selected as target species for the funnel fishery, and conger eel, Conger myriaster, was target species for the trap fishery. For assessing indicators of four management objectives, that is the maintenance of sustainability, biodiversity, habitat quality and socio-economic benefits, indicators were selected considering the availability of data, which were 5 indicators for sustainability, 3 indicators for biodiversity, 4 indicators for habitat, 2 indicators for socio-economic benefit. The objective risk index for sustainability and biodiversity of two fisheries were estimated at yellow zone, medium risk level. The objective risk index for habitat and socio-economic benefit were estimated at green zone, safe level. The species risk indces (SRI) were estimated at yellow zone. The fishery risk indices (FRI) were estimated at 1.143 and 1.400 for funnel net fishery and trap fishery, respectively. Finally the ecosystem risk index estimated at 1.184

박희원(Park, Hee-Won),송해덕(Song, Hae-Deok) 숭실대학교 영재교육연구소 2020 Global Creative Leader Vol.10 No.2

본 연구의 목적은 공공기관 근로자가 인식하는 직무특성이 혁신행동에 어떠한 영향을 미치는지를 살펴보는 것이다. 또한, 그 관계에서 공공봉사동기와 직무몰입이 가지는 매개효과를 실증하여 이들 변인들 간 구조적 관계를 탐색해보고자 하였다. 특히 직무특성 인식을 사회교환이론의 관점에서, 수행하는 직무가 갖는 사회적 가치와 사회적 영향에 대한 인식으로 구분하였다. 본 연구를 위해 국내 공공기관 근로자 495명으로부터 자료를 수집하여 구조방정식모형을 활용하여 분석하였다. 연구결과 사회적 가치에 대한 인식은 혁신행동에 유의미한 영향을 미치지 않았다. 반면 사회적 영향에 대한 인식은 공공봉사동기, 직무몰입, 그리고 혁신행동에 긍정적인 영향을 미치는 것이 확인되었다. 이는 공공기관 근로자는 정책수혜대상자들과의 상호작용을 통해 직무의 영향력이 강한 것으로 인식할 때 공공봉사동기와 직무몰입을 통해 혁신행동이 강화된다는 점을 보여준다. 따라서 공공기관 근로자의 혁신행동을 유도하기 위해서는 직무 영향력을 확인할 수 있는 경험이 중요하다는 것을 알 수 있다. 연구결과를 바탕으로 공공기관 근로자의 혁신행동을 촉진하기 위해서는 이러한 친사회적 직무특성을 고려할 필요가 있음을 제시하였다. The purpose of this study is to examine how the job characteristics perceived by employees of public institutions affect their Innovation Behavior. It also explored whether PSM (public service motivation) and WE (work engagement) had a mediating effect in the structural relationship. The perceived job characteristics were divided into Social Worth and Social Effect from the perspective of social exchange theory. For this study, the data collected from 495 employees of public institutions in South Korea were analyzed using the structural equation model. Findings have shown that perceived Social Worth did not have a significant effect on innovation behavior. On the other hand, perceived Social Effect had a positive impact on PSM, WE and IB. It has also been shown that innovation behavior is reinforced by PSM and WE when employees perceive the strong influence of their duties through inter-exchange relations with policy beneficiaries. Therefore, experience in identifying job influence is important to induce innovative behavior of workers at public institutions. Based on the findings, it was suggested that prosocial job characteristics should be considered in order to promote innovative behavior of employees at public institutions.

박희원 ( Hee Won Park ),김형섭 ( Hyung Seop Kim ),조수근 ( Soo Gun Jo ) 한국수산과학회(구 한국수산학회) 2016 한국수산과학회지 Vol.49 No.3

The aim of this study was to verify the performance of Teleaulax amphioxeia as prey for Brachionus plicatilis and for the larvae of the bivalves (Pacific oyster Crassostrea gigas and Manila clam Ruditapes philippinarum) to select the best of five T. amphioxeia strains. The five strains of T. amphioxeia were collected from the coasts of Korea, purecultured and then fed to the rotifer and bivalve larvae. The density and fecundity rate of the rotifer fed on strain 01 were the highest. The instantaneous growth rate of the rotifer fed strain 08-2 was the highest. The maximum density and fecundity rate of the rotifer fed strain 08-2 were significantly higher than those fed Chlorella ellipsoidea, while instantaneous growth rate showed the opposite pattern. Survival rates of the Manila clam larvae fed each strain of Teleaulax showed no significant difference between strains. Survival rates of the Pacific oyster fed Teleaulax were significantly higher than those fed Chaetoceros sp., but lower than those fed I. galbana. This study indicates that strain 08-2 showed better growth for B. plicatilis and better survival for the bivalve larvae than did the other strains, and that T. amphioxeia can also be used as a prey organism for rotifers or bivalve larvae.

The aim of this study was to find a specific factors that effect to deepening the maturity of strategic HRD which emerges as a new mainstream in the field of human resource development. To put it concretely this study sought to measure the empirical relationship between HRD practitioners` value priority and the strategic maturity of HRD of their organizations. In order to induce the result, the investigator carried out the survey by 93 HRD practitioners in various South Korean organizations. Based on the HRD value matrix and survey items designed by Bates and Chen(2004) as well as the strategic maturity of HRD model designed by McCracken and Wallace(2000b), the strategic maturity was measured through correlation and regression analysis. The result of this research can be summarized as the follows. First, there exists specific value priorities of HRD especially `Building Socially Responsible Organization`, `Improving Individual Job Performance` and `Improving Organizational Performance` have the correlation with the nine characteristics of strategic HRD. And these three HRD value priorities influences characteristics of strategic HRD. Second, the extent of correlation level between the HRD value priorities and the characteristics of strategic HRD is `Improving Organizational Performance` > `Building Socially Responsible Organization` > `Improving Individual Job Performance` > `Building Learning Systems` > `Providing Individuals with Learning Experiences` > `Enabling Meaningful Work`. Especially, the `Improving Organizational Performance` value and of `Building Socially Responsible Organization` value influence to the maturity of strategic HRD. Based on the above outputs following results can be derived. First, there exists the specific priorities of HRD those can deepen the maturity of strategic HRD. And it shows that HR practitioner should be a changing consultant rather than a training program provider. Second, the results tell that `Building Socially Responsible Organization` value influences maturity of strategic HRD more than `Improving Organizational Performance`. It means that organizations which emphasize social responsibility of corporation like ethic management or social contribution of corporation would be more strategic in their HRD activities. So if they want to reach higher level of strategic maturity an organization should emphasize the social responsibility activity. 본 연구는 인적자원개발 분야의 새로운 주류를 형성하기 시작한 전략적 인적자원개발을 심화시키기 위한 방안으로서 인적자원개발 담당자의 가치지향성과 전략적 인적자원개발의 실증적 관련성을 찾기 위한 것이다. 이를 위해 국내 기업 인적자원개발 담당자를 대상으로 설문조사를 실시하여 Bates와 Chen(2004)이 제시한 인적자원개발 가치지향성수준과 McCracken과 Wallace(2000b)가 제시한 전략적 인적자원개발 특성 및 전략적 성숙도간 상관관계분석 및 회귀분석을 실시하였으며, 주요 연구 결과는 다음과 같다. 첫째, 전략적 인적자원개발의 특성과 상관관계를 가지며 유의미한 영향을 끼치는 인적자원개발의 가치지향성은 `사회적으로 책임 있는 조직 확립`, `개인의 직무성과 개선`, `조직의 성과개선` 가치지향성으로 확인되었다. 둘째, 인적자원개발의 전략적 성숙도와 상관관계를 가지며 유의미한 영향을 끼치는 가치지향성은 `조직의 성과개선` 및 `사회적으로 책임 있는 조직 확립` 가치지향성으로 나타났다. 본 연구 결과를 통해 기업의 사회적 책임을 강조하는 가치지향성이 조직의 성과개선을 추구하는 가치지향성보다 인적자원개발의 전략적 성숙도에 더 큰 영향을 미치는 것을 알 수 있는데, 이는 최근 급속히 증가하고 있는 윤리경영, 사회공헌활동 등 기업의 사회적 책임을 실천하는 것이 기업의 인적자원개발 전략화에도 긍정적 영향을 미친다는 것을 보여주는 것이다. 따라서 기업의 사회적 공헌활동 수준을 높임으로써 인적자원개발의 전략화를 추구할 수 있음을 알 수 있다.

This study identified problems of the existing ecosystem-based fisheries assessment approach, and suggested new methods for scoring risk and for the estimation of fishery risk index. First, risk scores of zero to two for target and limit reference points for each indicator were replaced by those of zero to three, and the risk scores were calculated from new formulae which were developed in this study. Second, a new method for estimating fishery risk index (FRI) was developed in this study, considering the level of indicators. New method was applied to the Korean large purse seine fishery, large pair trawl fishery and drag net fishery. More precise and detailed risk scores were obtained from the new method, which can explain the risks by the wider range of both risk levels for ``better than target`` and ``beyond limit``. The new method for estimating FRI could avoid the basic problem related with duplicated computations of fishery-level indicators, which improved the estimated FRI to be more accurate. Also, a method for estimating variance of FRI using the bootstrap was proposed in this study.
