We examined the comparative spawning ecology of daggertooth pike conger Mureanesox cinereus and common pike conger M. bagio in the South Sea of Korea from May 2018 to December 2019. In the South Sea of Korea, the mean total length (TL) of M. cinereus was significantly smaller than that of M. bagio. The sex ratios of both species were skewed toward females. The spawning period of M. cinereus was from June to October, while the spawning period of M. bagio was from August to October. The lengths at 50%, 75%, and 97.5% sexual maturity of M. cinereus females were estimated as 54.6 cm, 60.4 cm, and 74.1 cm TL, respectively. It was not possible to estimate lengths at sexual maturity for M. bagio in the South Sea of Korea due to the absence of immature stages.

The community composition and distribution of fish species in the middle of the Yellow Sea were investigated in summer from 2008 to 2014. A total of 72 demersal fish species from 46 families and 17 orders were collected. The most common species were Larimichthys polyactis, Engraulis japonicus, and Chaeturichthys hexane, which accounted for 72.0% of the total number of individuals while Liparis tanakai, Larimichthys polyactis, and Lophius litulon accounted for 67.8% of the total biomass. A cluster analysis based on the Bray-Curtis similarity revealed that the fish community fell into three groups, according to latitude. Principal Component Analysis (PCA) and correlation analy-sis showed that variation in bottom water temperature could act as an indicator of variation in community structure and abundance of the dominant species. Characteristics of fish communities, such as the number of species, the total number of individuals (/km²), and biomass (/km²), were highly correlated with bottom water temperature and depth.

본 연구는 경제적 소득 수준과 더불어, 중년기와 노년기의 경제적 불안정이 장애인과 비장애인의 자살생각에 미치는 영향을 비교 분석하고자 하였다. 이를 위해, 한국복지패널 7차부터 14차까지의 8개년도 자료를 활용해 일반화 선형혼합 로지스틱 회귀분석을 실시하였다. 분석 결과, 비장애인에 비해 장애인의 자살생각 경험률이 더 높았고, 경제적 불안정이 중년기와 노년기 자살생각에 미치는 영향은 장애인과 비장애인에서 다르게 나타났다. 장애인의 경우, 경제적 불안정 각 요인의 독립적인 영향이 확인되었으나, 요인들을 하나의 모형에 포함한 결과 유의한 영향은 사라졌다. 비장애인의 경우, 소득수준이 증가할수록 자살생각이 감소하는 가운데, 소득 변동이 노년기 비장애인의 자살생각 증가에 유의한 영향을 주었고, 경제적 갈등 경험은 비장애인의 자살생각 증가에 유의한 영향을 주었다. 본 연구결과는 장애인과 비장애인의 정신건강 향상을 위해 경제적 수준뿐 아니라 경제적 불안정을 함께 고려해야 함을 시사한다. This study aims to compare the effects of economic insecurity on suicidal thoughts in middle-aged and older adults with and without disabilities. In this study, we analyzed the data from Korea Welfare Panel 7th-14th wave surveys. A generalized linear mixed logistic regression was conducted to examine the relationship considering repeated measurements. The results show that people with disabilities had a higher risk of suicidal thoughts than those without disabilities. The effect of economic insecurity on suicidal thoughts differed between those with and without disabilities. Specifically, there was an independent effect of each factor of economic insecurity; but there was no significant effect in the overall model of factors of economic insecurity among people with disabilities. Suicidal thoughts were likely to increase as the overall income level decreased, income volatility (year-on-year income changes) and family economic hardships were associated with higher risk for suicidal thoughts in people without disabilities. The results suggest that not only the level of economic status but also economic insecurity should be considered in order to improve the mental health of people with and without disabilities.

경영자보상과 전략에 따른 성과지표의 활용

Shank and Govindarajan(1992) 등은 경영자보상을 위해 회계성과지표는 물론 비재무적 성과지표나 주식수익률 등을 기업의 전략적 특성에 따라 활용해야 한다고 주장한다. 그러나, 우리나라의 경우 경영자보상에 관한 연구가 활발하지 않으며 특히 경영자보상의 차별성이 기업성과에 미치는 영향에 관한 실증적인 연구가 부족한 실정이다. 본 연구는 국내기업들이 기업의 전략적 특성에 맞추어 적절한 성과지표를 사용하여 경영자보상을 하고 있는지를 실증분석했다. 기업의 전략을 설문조사 대신 객관적인 재무자료를 이용하여 차별화전략, 원가우위전략으로 나누었고, 전략별로 나눈 기업들을 회귀분석함으로써 경영자 현금보상에 영향을 주는 성과지표를 전략별로 분석하였다. 또한 기업이 전략에 적합한 성과지표를 사용하여 합리적인 경영자보상을 하였을 경우, 기업성과가 향상되는지를 분석하였다. 분석결과는 다음과 같다. 첫째, 원가우위전략을 채택한 기업과 차별화전략을 채택한 기업 모두에서 자기자본이익률(ROE)과 주식수익률이 경영자보상에 비유의적인 변수로 나타났다. 즉, 전략에 상관없이 두 가지 성과지표 모두 비유의적이어서, 우리나라 기업들은 경영자보상을 위해 전략적인 특성에 따라 성과지표를 활용하고 있다고 보기 어렵다. 이는 기업들이 전략적 특성에 맞추어 합리적인 방향으로 경영자 보상계약을 개선할 필요성이 있음을 시사해준다. 둘째, 비록 대부분의 기업이 전략에 맞게 성과지표를 활용하지 못하고 있지만, 소수의 기업이 전략에 적합한 성과지표를 활용하여 경영자 보상계약을 하고 있었고, 이들 기업들의 경우 전략에 맞춘 성과지표의 활용으로 인한 성과증진의 효과를 보였다. 이는 Rajagopalan(1996), Said, HassabElnaby and Wier(2003)의 연구와도 일치하는 결과이다. 따라서 다른 국내의 기업들 또한 기업성과의 증진을 위해 전략적 특성에 맞는 합리적인 경영자보상이 필요함을 시사한다. This study examines whether there is a fit between strategic orientations and performance measures used in executive compensation plans in Korean companies. Companies' strategic orientations are classified based on financial data instead of survey question items. Regression analyses are made to examine performance measures used in executive cash compensation contracts for each of cost leadership and differentiation strategy samples. Also examined is the performance implication of the fit between strategy and performance measures used. The results show neither ROE (return on equity) nor stock return is significantly associated with executive compensation in both samples, which is inconsistent with the predictions made in strategic management literature. This finding suggests that companies need to take advantage of strategy-consistent performance measures in executive compensation contracting. Unlike the majority of companies, a few companies exhibited strategy-consistent use of performance measures. Additional analysis indicates the fit between strategy and performance measures employed leads to performance improvement in these companies. The results imply other companies can improve their performance by adopting strategy-consistent performance measures in compensation contracting.
