西瓜의 開花狀態와 各 種蔓의 結果習性과 授粉時刻이 結果에 미치는 影響
姜炳九,朴平秀 진주산업대학교 1978 論文集 Vol.16 No.-
This experiment was Cried out to investigate the influence of fruiting habit of Various rnnner and pollinating time on fruitiny of Water mellon at the field, located at well lighted and Well Ventilated, Slugish Sloped mountain. The results obtained in this experiment were as follows. 1. Female flower were mainly Set at from sixth to twentyfith node of main runer, but any fruit was not beared at from the sixth to tenth node and then from twenysith to thirtieth node, fruits were beared well. 2. Female flowers were almost beared at from eleventh to fiftenth node of sun runer and grandson runer, and many fruits were beard at them. 3. At the number of fruit per plant to the total female flower, main runer. Son runer. grandson runer was 17%, 5%, 25%, respectively. 4. Main runer, Son runer, grandson runer 4.4㎏, 26.8㎏, 9㎏ in the yields, respectively. 5. Latenal sterns were set at third to fourth node were vigorous and had many yields. 6. When the pollinaion was imidiathely done floweriug, from nine to ten O'clock, fertility rate was good. 7. When the pollination was done at five to six O'clock and after twelve O'clock, fertility rate was bad, 8. Pollination time was delayed at the Cloudy days.

강병구 한국사회보장학회 2004 사회보장연구 Vol.20 No.2
한국보건사회연구원에서 실시한 『저소득층 자활사업 실태조사』 자료를 분석한 결 과 2002년 우리나라의 시장소득 기준 상대적 빈곤률은 20.75%로 추정되지만, 공적이전소득의 빈곤감소효과 및 노동공급 감소효과는 매우 미약한 것으로 평가되었다. 사회보험급여를 포함한 공적 이전소득은 전체 가구의 2.21%(약 329천 가구)만을 상대적 빈곤으로부터 구제하였으며, 빈곤계층의 평균소득갭을 9.17% 축소시키는데 불과하였다. 또한 공적 이전소득의 소득분배 개선효과는 동등화지수를 0.5로 할 경우 지니계수를 0.01945 포인트(5.51%) 감소시키는 것으로 나타났다. 사회보험급여를 포함한공적 이전소득이 연간 100만원 증가할 때 남자세대주와 여자세대주의 연간 노동시간은 각각 81.6시간(1.06%)과 15.6시간(0.76%) 감소하고, 공적 이전소득의 노동공급탄력성은 비근로소득에 비해 매우 작은 것으로 나타났다. 향후 우리나라의 공적 이전지출 정책은 예산의 절대 규모를 증대시켜 빈곤층의 보호를 확대하는 가운데 노동공급의 감소로 인한 경제적 비효율의 발생을 최소화시키는 방향으로 추진되어야 한다. 특히 고용보험제도의 근로유인체계를 강화하고, 국민기초생활보장제도의 경우 근로능력이 있는 조건부수급자에 대한 근로유인체계를 개선할 필요가 있다. Since the economic crisis in 1997, there has been increasing demand for the expansion of social welfare expenditures in Korea. At the same time the welfare system has been criticized by its inefficiency. According to the analysis with National Survey on the Low-Income Classes and Self-Reliance Program, the relative poverty rate which is measured in terms of the 50% of household median income was 20.75% in 2002. The same analysis showed that the effects of government transfer programs on poverty reduction and income redistribution were insignificant. Also, the negative effect of government transfer programs on labor supply was smaller than that of unearned income. Implications derived from the analysis are as follows. While the government transfer programs should be expanded to protect the poor, the Korean welfare system should be restructured to minimize welfare loss. For the efficient transfer programs need to closely link with active labor market policies.

Smartphone is becoming as a core device of mobile environment. The purpose of this study is to investigate the factors affecting customer's buying decision on smartphone. Based on prior studies and cases, this study identifies network effect, switching cost, function, design, brand, after service, price as affecting factors of customer's buying decision on smartphone. It also aims to investigate the relationship between network effect/switching cost and re-purchasing. Result shows that network effect, brand, after service are significantly related to customer's buying decision on smartphone by device types, but switching cost, function, design, price are not. Network effect also was found to be significantly related to the re-purchasing. The result of this study may provide a guideline of supply strategy with smartphone suppliers.

傾斜地 果樹園의 開園方法과 土壤管理法이 土壤含水量에 미치는 影響
姜炳九 진주산업대학교 1968 論文集 Vol.2 No.-
傾斜地 果樹園에서 一般的으로 시행되리라 생각되는 開園方法과 土壤管理法을 試驗區로 삼아 이들 試驗區에 있어서의 土壤含水量을 調査하였는데 그 結果는 다음과 같았다. (1)土壤含水量은 開園方法에 따른 有意性은 없었다. (2)土壤管理法 相互間에는 敷草區一淸耕 區一草生區의 順位로 含水量이 높고 特히 敷草區는 월등히 높았다. In order to investigate the effect of different establishment methods and soil management systems in the hillside orchard on the soil moisture, this study was disigned. Result of this study, we observed that there was no significant difference between various establishment methods, but high significant difference (1% level) between soil management systems in soil moisture.

오스테나이트계 TP347 스테인레스강의 파괴저항특성 평가
강병구,김수용,석창성 成均館大學校 科學技術硏究所 1999 論文集 Vol.50 No.1
The objective of this paper is to evaluate the material properties of TP347 stainless steel and their associated welds and the welded joint of the carbon steel and the stainless steel manufactured for primary coolant system of Ulchin 3 & 4 nuclear power plants. The effect of various parameters such as pipe size, welding method, chemical composition, crack plane orientation, metallography and fractography on the material properties were discussed. Test results showed that the effect of pipe size on fracture toughness was negligible while the effect of welding method on fracture toughness was significant. In addition, the drop of fracture toughness in the field fabrication weld of TP347 stainless steel is probably due to the large amount of σ-phase precipitated on the δ-ferrite boundary and the large size dimple.

강병구 한국재정정책학회 2007 財政政策論集 Vol.9 No.1
케인즈는 실업의 원인과 대안을 제시함에 있어서 고전학파 경제학의 한계를 인식하고 유효수요이론을 제시하였다. 당시로서 이러한 주장은 개혁적이었고, 그 문제의식은 이후 케인지안 경제학자들에 의해서 공유되고 있다. 1930년대 이후 케인즈 경제학은 다양한 분파를 형성하면서 내적인 발전 또는 변화를 이루고 있지만, 이론 및 정책의 측면에서 개인주의적 사회유기체관, 인간본성의 불완전성과 불확실성, 단기 중심적 성격, 다원주의 국가론 등을 특징으로 하고 있다. 이러한 케인즈 경제학의 특성은 재량적 재정정책, 거시경제의 자동안정장치, 투자의 사회화 등을 주된 내용으로 하는 개혁주의적 재정론의 전제를 구성한다. 1970년대 스태그플레이션에 직면하여 케인즈 경제학은 일대 위기를 맞이하였지만, 안정화정책의 중요성은 여전히 케인지언 경제학자들에 의해 공유되고 있다. 특히 1990년대 이후 각국이 직면하고 있는 고실업율, 분배구조의 악화, 양극화 등의 문제는 개혁주의적 접근방법의 재조명을 요구하고 있다. Keynes denied the Say's Law and suggested active fiscal policy for full employment. The idea was revolutionary in those days. While Keynes economics has changed a lot since that time, Keynesian economists share its main idea until now. The methodological characteristics of Keynesian economics consist of individualistic organicism, imperfection of human nature, uncertainty, short-run prospect, and the pluralist perspective on democratic politics etc. These are the prerequisites of discretionary fiscal policy, automatic stabilizer, and socialization of investment in Keynesian economics. While Keynesian ideas were criticized by free market economists with stagflationof the 1970s, Keynesian economists still recognize the importance of stabilization policy in modern economy. Moreover, the reformist view of Keynes needs to be reviewed in the face of high rate of unemployment, aggravation of income distribution, and polarization since the 1990s.
