Daily rainfalls and evaporations from copper pan measured in Suweon from 1964 to 1996 were figured respectively so that past soil moisture deficits can be understood clearly at a glance in relation to the characteristics of weather. Past drought intensities in Suweon were computed on the basis of Oh's 50mm pan model estimating drought in terms of daily, monthly shortage of evapotranspiration and growthless time fraction. Yearly differences in drought seem to result mainly from yearly differences in rainfall distribution and intensity, because there is the periodical similarity in evaporation from year to year. The most intense drought continued from December, 1964 to June, 1965 for 190 days and the most frequent rainfalls were observed from June, 1989 to August, 1990 for 15 months. The applied Oh's drought estimation model was reinforced with figuring programs with a view to later application for other districts. Present economic value index of irrigation were distributed in the range of 120% to 210% of one season yield for spring chinese cabbage, calculated on the basis of 10 year's accumulation of its expectable future yield increase. Therefore, the same value can be invested for the installation of new irrigation system even only for spring chinese cabbage, if its depreciation period is 10 years.

발주잔량의 감소와 세계경기 회복기조 등을 감안할 때, 수급여건은 저점에 근접해 있다. 그러나, 해상물동량 증가율의 둔화, 대형선박 위주로 되살아난 발주 등을 감안할 때, 운임지수 등 시황회복은 상대적으로 느리게 진행될 전망이다. 2012년부터 상위선사의 뚜렷한 실적차별화가 나타나고 있으며, 국내선사는 상대적으로 취약한 선종다각화와 자본력, 계열 및 정부의 저조한 지원 등으로 금융위기 이후 재무구조가 가장 큰 폭으로 악화되었다. 상위선사의 실적우위는 일시적 차이가 아닌 선박의 대형화와 높은 연료효율성, 우수한 글로벌 네트워크 등 구조적 원가경쟁력의 차이에 기인하고 있다. 상위 3개 선사는 초대형선박의 추가인수와 P3 Network 구축으로 원가경쟁력이 더욱 향상될 전망이며, 재무여력을 갖춘 경쟁선사들도 선박가격이 낮은 상황에서 고효율의 대형선박을 발주, 원가경쟁력을 제고하고 있다. 반면에 호황기 고가에 선박을 확보한 국내선사는 과중한 재무부담으로 인해 선박대형화와 글로벌 네트워크 구축에 동침하지 못하고 있어 원가경쟁력의 차이는 더욱 심화될 전망이다. 더딘 시황회복과 상위선사의 단위당 운송비(Unit Cost) 하락 등을 감안할 때, 빠른 시일 내에 운임상승을 통한 큰 폭의 성과개선을 기대하기 어렵고, 과중한 재무부담은 투자여력의 위축으로 이어지고 있다. 여기에 중국 유럽선사가 정부로부터 대규모의 직접적 지원(대출, 지급보증)을 제공받고 있는데 반하여, 우리 정부는 장기적 관점의 지원이나 대책을 유보한 채, 제한된 유동성 지원만을 하고 있다. 재무부담에 따른 악순환을 깨고 원가경쟁력을 확보하기 위해선, 비핵심자산 매각, 자본유치 등 구조조정을 통한 재무구조 개선, 투자여력 확보를 통한 글로벌 경쟁력 회복, 정부차원의 지원과 조정 등 가능한 모든 방안을 총 동원하여 재무구조를 개선하고 투지에 나서는 것이 시급하다. 하지만, 불황으로 체력이 소진된 해운사의 자체적인 노력만으로는 한계가 있다. 기간산업의 국가경쟁력 차원에서 국내 선사의 자체노력은 물론, 정부 또는 금융기관 등 유관기관들의 확실한 지원이나 의사결정이 필요한 시점이다. 그렇지 않을 경우 국내 해운산업은 어두운 터널의 끝을 벗어나지 못하고 글로벌 경쟁사와의 격차는 더욱 벌어지게 될 것이다. 다음은 한국신용평가에서 발표한 "풍전등화 국내 해운업계, 본원적 대책 마련 시급"의 주요 내용을 요약 정리한 것이다.

The importance of social responsibility such as ethical management and social contribution activities is emphasized for the sustainable growth of companies. Although there is a great deal of research on corporate social responsibility due to the increase in social interest and expectation, most of them have been limited to research on general manufacturing industry. The purpose of this study is to analyze the effect of social responsibility activities on financial performance. In addition, we want to analyze the difference in the financial performance of companies with excellent social responsibility activities announced by the Institute of Economic Justice and others. The analysis period is from 2011 to 2016, and we analyze using the robust regression methodology which is relatively effective in solving the autocorrelation and this dispersion problem. First, it is proved that the higher the KEJI index, the more positive effect on financial performance. In addition, we found that there is a significant difference in the financial performance of companies with excellent social responsibility activities and those with other social responsibility activities. These results will have important implications for establishing a firm's financial strategy and will serve as useful information for the financial industry that is striving for sustainable management.

This study investigates the effect of mimicry buying on differentiation behavior in the context of fashion product consumption. Merging insights from social identity theory, optimal distinctiveness theory and previous research on narcissism, this article presents ingroup-outgroup categorization, narcissistic tendency and social status to serve as boundary conditions of this effect. Experiment 1 supports the hypothesis that more differentiation behavior against mimicry buying is reinforced when the mimicker is an in-group member compared to an out-group member. Based on this result, we conducted Experiment 2 to understand the effect of narcissistic tendency and mimicker's social status on differentiation behavior in the in-group context. The results show that the effect of narcissistic tendency on differentiation behavior is mediated by a perceived distinctiveness threat when the mimicker is an in-group member. In addition, this mediating effect is moderated by the mimicker's social status. Narcissistic tendencies have a direct negative effect on differentiation behavior when the mimicker is an in-group member with a high social status. However, high narcissistic tendency induces a more distinctiveness threat when the mimicker is an in-group member with a low social status. This then results in a greater differentiation behavior. Implications for marketers and suggestions for future research are also discussed.

This purposed of this study was to investigate the effect of empathy on social justice commitment from a social-cognitive perspective. Specifically, we examined how cognitive and affective empathy affect social justice commitment through social justice self-efficacy, social justice outcome expectation, and social justice interest which represent a social-cognitive path of behavior. Based on the self-report survey sample of 537 people in their twenties, we first controlled social desirability, and then analyzed the measurement and structure model using Structure Estimate Modeling(SEM). As a result, it turned out that both cognitive and affective empathy indirectly affected social justice commitment through the path of the social-cognitive model. However, affective empathy had a larger effect size compared to cognitive empathy. Results suggest that empathy competence has an effect on not only general altruistic behavior as known before but also social justice behavior which include the value of equality and anti-discrimination. Finally, ways for facilitating social justice commitment in terms of cognitive and affective empathy were suggested.

Since the onset of the COVID-19 pandemic, there has been a significant shift in the lifestyle patterns of the populace across various domains. Concerns surrounding COVID-19 have emerged as pivotal catalysts of change in recreational habits with people giving a particular preference for environments with low population density and increased openness. This trend has resulted in an uptick in excursions to natural reserves, coastlines, and parks. However, during the peak of infectious outbreaks, widespread adherence to social distancing measures has precipitated a steep decline in tourist footfall across natural recreation forests, exacerbating financial deficits to a considerable extent. Thus, this research sought to compare and analyze the operational efficacy and productivity of national, public, and private natural recreation forests pre- and post-COVID-19 pandemic by utilizing non-parametric methodologies, such as data envelopment analysis and the Malmquist productivity index analysis. The objective was to identify the factors contributing to the decreases in efficiency and productivity and ultimately offer nuanced recommendations tailored to respective administrative bodies. This study's distinctive focus on the analysis of management efficiency and productivity in natural recreation forests nationwide offers significant academic and practical relevance.

The purpose of this study was to validate Preschool Child Observation Record-II developed by High/Scope for Korean preschool children. The subjects of the study were 255 children aged three to six attending child care centers and their head teachers. They were observed for at least two months and completed the Korean version of Child Observation Record-II(K-COR-II). K-COR-II consisted of six categories and 32 items which had five-level-rubrics. The results from an exploratory factor analysis identified one dimension of the scale, there was no evidence of discriminant validity even after face validity was examined. The concurrent validity and internal consistency of the revised scale were relatively high. Also, the mean between the upper and lower groups with regard to item discrimination showed significant difference. It was concluded that K-COR-II can be used as a valid and reliable instrument to various aspects of preschool children's development.

The study was to investigate and compare plants and frequency of appearing species of vegetation transect in a straight and a restoration Section of Bulgwang stream in Seoul. Some part of Bulgwang stream was restored as a closed-to-nature stream. This present study consists of two investigations, the first investigation being conducted on May and the second one on August -September 2003. Based on the analysis of the data collected from both investigations, this study classified and listed all of the plants appeared in a straight and a restoration section of the stream. The study used the Belt-transect method in order to examine and analyze discover the appearance frequency of the vegetaton transect per 200 meters. During the period of the first investigation and the second one, plants of 33 families, 73 classes, and 88 species appeared in the straight section, while plants of 36 families, 76 classes, and 90 species appeared in the restoration section. The Naturalized Index of the straight section was 22.7％, and that of the restoration section was 21.1％. As shown on the results indicating that the Urbanization Index of the straight section was 7.8％, and that of the restoration section was 7.4％, the Urbanization Index of the straight section was slightly higher than the restoration section. The results using belt-transect analysis method showed that in case of the straight section, the plants of the highest appearance frequency on the riverside were Persicaria hydropiper and Humulus japonicus. On the contrary, in the case of restoration section, the plants showing a higher appearance frequency on the riverside were identified as Salix gracilistyla, Persicaria hydropiper, Rumex crispus, and Humulus japonicus. In conclusion, there was no difference between the straight and the restoration section in the bank with regard to vegetation transect. However, a remarkable difference was found on the riverside for the Salix gracilistyla which was introduced in the restoration section.

This survey was carried out to investigate the occurrence of reproductive disorders in Korean native cattle (Hanwoo). The general management status such as barn type, feed intake, parity and type of reproductive disorders were examined in the Hanwoo farms. In this survey, the total incidence of reproductive disorders that was assessed from 54 Hanwoo farms was 11.6% (73/ 631). We first examined the incidence of reproductive disorders following herd size per farm. The rates of reproductive disorders in under 10 heads, 10 to 20 heads and over 20 heads were 25.2%, 9.4% and 8.3%, respectively (P<0.05). The rate of reproductive disorders in tie stall barn was significantly (P<0.05) higher than that in free stall barn (14.9% vs. 8.1%). The major types of reproductive disorders were follicular cysts (21.8%), fat necrosis (21.8%), and repeat breeding (17.8%). The rate of reproductive disorders assessed by the parity tended to decrease as the parity increased. The relationship between incidence of reproductive disorders and body condition score (BCS) was investigated in 203 Hanwoo. The incidence of reproductive disorder was 80.0%, 8.8%, 9.4%, 10.0%, 33.3% and 57.1% at 1.5, 2.0, 2.5, 3.0, 3.5 and 4.0 of BCS, respectively. These data show that the increase of herd size, barn type and BCS affect the incidence of reproductive disorders such as follicular cysts, fat necrosis and repeat breeding in Hanwoo.

This study was carried out to investigate the relationship between frequency of soft and broken eggs and the economic traits for colored laying hens using the data sampled 7 times in Korea from 1985 to 1991. In addition, the correlation coefficients of frequency of soft and broken eggs on the economic traits for colored laying hens in order to decrease the frequency of soft and broken eggs were studied. The results obtained were summarized as follows ： 1. For colored laying hens, mean of the sexual maturity(SM) was 163.6 days, hen-day egg Production(HDEP) was 79.49％, hen-housed egg Production(HHEP) was 272.9 eggs, egg weight (EW) was 62.69g and the frequency of soft and broken eggs was 1.363％ during 18∼72wks. For white laying hens, SM was 157.2 days, HDEP was 77.87％, HHEP was 265.1 eggs, EW was 60. 26g and the frequency of soft and broken eggs (FSBE) was 1.174％ during 18∼72wks. 2. Statistical significances were observed in laying viability, SM, HDEP, FR, BW and FSBE during 18 ∼72wks and 18 ∼78wks by year for colored laying hens. 3. Sexual maturity was shortened from 168.5 days to 155.9 days. FSBE decreased from 1.4∼l.69％ to 0.94∼o.89％ during 18∼72wks, and HDEP was increased from 74.5∼75.1％ to 77.8∼80.6％, HHEP was increased to 302.0∼304.6 eggs and FSBE was increased from 1.54∼2.02％ to 0.98％ during 18∼78wks in colored laying hens. 4. Estimate of correlation coefficients between FSBE and trait of SM, EW, 72 wks BW were 0.3985, 0.1072, 0.4225, and those of HDEP, HHEP, FR were -0.5662, -2896, -0.245 during 18∼72wks In colored laying hens, respectively. 5. Estimate of correlation coefficients between FSBE and traits of SM, EW, 78wks BW were 0.3791, 0.1171, 0.4609, and those of HDEP, HHEP, FR were -0.5041, -0.2372, -0.2421 during 18∼78wks in colored laying hens, respectively.
