This study examined the factors influencing the relationship between anger and happiness of university nursing students so that they can improve their happiness and perform their studies with better internalized values. The general characteristics, academic efficacy, self-directedness, self-resilience, anger scale, and subjective happiness of 401 nursing students were measured. The differences between these groups were analyzed using t-tests and ANOVA tests. Correlations among academic efficacy, self-directedness, self-resilience and psychological states were calculated using Pearson's correlation coefficient. Multiple group analysis was conducted for assessing the interaction effects of academic efficacy, self-resilience and self-directedness. Subjective happiness and predictors of the study (self-directedness and ego-resilience) were positively correlated with statistical significance. The lower the self-directedness was, the higher the subjective happiness that is reduced by anger was. The higher the self-elasticity, the lower the degree of the subjective happiness that is reduced by anger. Since the moderating effect of self-directedness has been demonstrated in the relationship between anger and happiness, it is necessary to consider instituting proper pedagogy so that the educational method of enhancing self-directedness can be reflected in the field of nursing.

The purpose of this study is to improve the reemployment rate of unemployed job seekers aged 50 to 59 by supporting the foundation of our society and enhancing their value of life. We analyzed the impact of resilience, a psychological factor, on job seeking of unemployed people in their fifties. Subjects were visited and provided employment services in the Employment Welfare Plus Center in the Seoul Metropolitan Area. We devised a questionnaire consisting of three variables of general characteristics, resilience, and job search. Also, the resilience variables comprised sub-variables of control, positiveness, and sociality, and the job search variables involved sub-variables of job preparation, attitude, and willness. Study results the resilience of unemployed persons aged 50 to 59 is above average, and sub-variables of positiveness are highest compared to other sub-variables. Second, there is no significant gender difference in resilience for job search activities. Third, resilience and its sub-variables, such as control and affirmation, affect job-seeking activities. Therefore, this study suggests strengthening the resilience of job seekers in their fifties as well as providing psychological counseling and job training for job-seeking activities.

Defense exports have overgrown in a short period, and items have been diversified with advanced high-end equipment, but exports have been stagnant due to the global economic recession and fierce competition. Weapons importers in the global market are diversified, volatility is higher, and global defense companies are also expanding their global value chain (GVC) By participating in the GVC of a global defense company, the defense SME can grow into a competitive company with specialized technology, rather than participating as a partner of a domestic system company. It is time to prepare an export promotion support plan. In this study, we selected five global companies with high value for the implementation of offset and general considerations on domestic SMEs' entry into the international parts supply chain and related cases, and investigated GVC entry requirements, the current status of cooperation partners, and the perceptions of GVC entry, through local surveys in Korea and overseas. Also, by considering the export target comprehensively, GVC stage, and the level of export competitiveness of domestic SMEs, strategies for promoting GVC participation of defense SMEs and improvements in government policies were derived and presented.

This study was intended to investigate physical characteristics of the bread with Laminaria powder. Three different powder concentration levels of 2.5%, 5% and 7.5% were added to flour to make the bread. The puffing rate, density, color, and texture were analyzed. Sensory evaluation was performed among female college students and housewives in their 50s. The volume of the dough during the fermentation and the final volume of the bread containing Laminaria powder was smaller than that of the dough without the powder. While adding the powder to the bread decreased the Hunter L (lightness) and a value (redness), it increased the b value (yellowness). In the texture analyzer measurement, hardness and fracturability of the bread were significantly increased by adding the powder and chewiness tended to increase. However, adhesiveness, springiness and cohesiveness were not significantly different among groups. As the result of the sensory evaluation, differences were observed between female college students and housewives in their 50s. In all indices of the sensory test, college students evaluated the bread with the powder lower than the bread without the powder, while the housewives preferred the bread with the powder. The bread containing 2.5% Laminaria powder obtained the most excellent scores. In conclusion, it is suggested that the bread with 2.5% Laminaria powder would be a highly acceptable bio-active product with proper physical characteristics.

두만강을 중심으로 한 동북아시아의 환경보호를 위한 우선순위에서 토양보호가 높은 순위로 분류된 적은 거의 없었다. 토양손실에 의한 부정적 효과가 사람들에게 잘 알려져 있지 않으며, 특히 농촌에서 토양 보전의 가치를 이해하거나 토양에서 직접적으로 혜택을 받고 있다고 인식하는 사람들은 극히 일부에 지나지 않는다. 실제 동북아시아에서 토양보호와 관련하여 일관되게 접근해야 할 필요성이 국가 정책에 반영되고 그 결과 토양유실보호법이나 환경보호법 내에서 우선순위의 국가정책으로 도입된 것은 불과 지난 10-20년 사이의 일이다. 따라서 이 지역에서의 토사 유실은 매우 심각하며 이로 인해 많은 분제점이 발생하고 있는 것은 당연하다. 수자원과 토지 자원을 잘 보전하고, 물과 토양의 침식을 제어하면서 생태계를 보호하는 것은 두만강 유역에 있는 연안 국가의 현대화를 위한 기초이자 장기 전략과제이다. 대상 지역에서, 토양의 침식형태는 주로 수리적 침식, 바람에 의한 침식, 결빙과 해동에 의한 침식, 산사태, 토석류, 밀도류 및 구릉의 함몰 등이 포함되며 이중 수리적 침식과 산사태에 의한 유실이 가장 일반적이다. 두만강 유역에서 자원의 이용 압력이 땅과 물의 퇴화를 유발한다는 증거가 많아지면서, 자연자원을 관리하는 방법에 더 많은 주의를 기울이고 있으나 퇴사량에 대한 근본적 이해 없이는 불가능해 보인다. 따라서 본 연구에서는 토지 이용관리와 토사를 보호하는 방법을 개발하기 위해 토양의 침식에 대한 현재 상태를 상세하게 확인하였으며, 토양의 중요한 기능이 심각한 퇴화 과정으로 인해 위협받고 있다는 인식에 토대를 두고 토양 보호 프로그램을 유도하기 위해 두만강의 유사량을 경험적 방법을 이용하여 추정하였다.포 분석방법으로는 BW관 방법을 이용하여 분석하였다. 현재까지 국내 외적으로 하천 유사량 산정과 관련된 많은 경험식들이 제시되고 있다. 하지만, 외국의 충적하천에 기초하여 개발되어진 유사량 공식들을 우리나라 하천에 무분별하게 적용하는 것은 위험스러우며, 유사량 산정 결과의 신뢰성을 높이기 위해서는 무엇보다 우리나라 하천의 지형, 수리, 수문학적 요소들이 유사 특성에 미치는 영향을 알아야 한다. 그러므로, 본 연구에서는 실측을 통한 유사량 값을 하천의 지형, 수리, 수문학적 요소들과 비교 분석하여우리나라 하천에 맞는 유사특성을 알아보고, 기타 총유사량산정 공식을 이용하여 실측한 유사량과 비교 분석하고자 한다.호강유역의 급격한 수질개선을 알 수 있다.世宗實錄) $\ulcorner$지리지$\lrcorner$(地理志)와 동년대에 동일한 목적으로 찬술되었음을 알 수 있다. $\ulcorner$경상도실록지리지$\lrcorner$(慶尙道實錄地理志)에는 $\ulcorner$세종실록$\lrcorner$(世宗實錄) $\ulcorner$지리지$\lrcorner$(地理志)와의 비교를 해보면 상 중 하품의 통합 9개소가 삭제되어 있고, $\ulcorner$동국여지승람$\lrcorner$(東國與地勝覽) 에서는 자기소와 도기소의 위치가 완전히 삭제되어 있다. 이러한 현상은 첫째, 15세기 중엽 경제적 태평과 함께 백자의 수요 생산이 증가하자 군신의 변별(辨別)과 사치를 이유로 강력하게 규제하여 백자의 확대와 발전에 걸림돌이

The purpose of this study is to resolve misunderstanding for centroid of a triangle and to clarify several logical problems in finding the centroid of a Polygon. The conclusions are the followings. For a triangle, the misunderstanding that the centroid of a figure is the intersection of two lines that divide the area of the figure into two equal part is more easily accepted caused by the misinterpretation of a median. Concerning the equilibrium of a triangle, the median of it has the meaning that it makes the torques of both regions it divides to be equal, not the areas. The errors in students' strategies aiming for finding the centroid of a polygon fundamentally lie in the lack of their understanding of the mathematical investigation of physical phenomena. To investigate physical phenomena mathematically, we should abstract some mathematical principals from the phenomena which can provide the appropriate explanations for then. This abstraction is crucial because the development of mathematical theories for physical phenomena begins with those principals. However, the students weren't conscious of this process. Generally, we use the law of lever, the reciprocal proportionality of mass and distance, to explain the equilibrium of an object. But some self-evident principles in symmetry may also be logically sufficient to fix the centroid of a polygon. One of the studies by Archimedes, the famous ancient Greek mathematician, gives a solution to this rather awkward situation. He had developed the general theory of a centroid from a few axioms which concerns symmetry. But it should be noticed that these axioms are achieved from the abstraction of physical phenomena as well.

일반적인 정보 검색은 색인어를 통해 이루어지는데 이런 경우 사용자는 정보를 검색하기 위해 데이터베이스에 저장된 정보들이 가지고 있는 색인어를 정확하게 입력해야 한다. 그러나 일반 사용자가 색인어를 정확하게 입력하기는 어렵고, 특히 찾고자 하는 분야가 전문 분야에서 사용되는 용어일 때는 더욱 그러하다. 이럴 때 시소러스와 같은 지식구조를 이용해서 색인어를 탐색하여 검색의 효율을 높일 수 있다. 최근 들어 정보기술 분야의 연구가 활발함에 따라 정보자로의 생산이 급격히 증가하고 이를 관련 주제 분야의 연구정보로 활용하는 경우가 증가하고 있다. 따라서 IT 분야의 정보를 관리할 수 있는 시스템의 개발이 시급하다. 또한 IT 분야와 같은 전문분야일 때 검색 시스템에서 사용할 용어의 관리에 대한 연구의 필요성이 증가하고 있다. 본 논문에서는 IT분야의 정보를 검색할 수 있는 IT 업체정보검색시스템에서 정보 검색시에 생기는 용어간의 불일치 문제를 해결하고, 각 용어들간의 계층 관계를 나타내어 정보 검색시 검색어의 확장을 도울 수 있는 용어 관리 시스템의 구조를 제안하고 그에 대한 검색 알고리즘을 제시한다. 제안된 구조는 사용자의 검색어에 대한 동의어 관계나 상위어, 하위어 등의 계층 관계를 파악하여 검색의 범위에 추가함으로써 검색 효율을 높일 수 있다. 또한 새로운 용어의 생성이나 삭제와 같은 연산이 발생했을 때 시스템을 동적으로 확장할 수 있도록 구현하였다. 제안된 시스템은 단어간의 계층 구조를 효율적으로 검색하기 위하여 객체-관계형 데이터베이스를 사용하였다. 또한 메모리 상주 DBMS를 사용하여 많은 사용자들이 동시에 접근하는 환경에서도 빠른 검색 성능을 유지할 수 있도록 하였다. 제시된 방법은 정보기술 분야뿐만 아니라 다른 전문용어 분야의 연구로도 그 범위를 확장 할 수 있다.자기자본비용의 조합인 기회자본비용으로 할인함으로써 현재의 기업가치를 구할 수 있기 때문이다. 이처럼 기업이 영업활동이나 투자활동을 통해 현금을 창출하고 소비하는 경향은 해당 비즈니스 모델의 성격을 규정하는 자료도로 이용될 수 있다. 또한 최근 인터넷기업들의 부도가 발생하고 있는데, 기업의 부실원인이 어떤 것이든 사회전체의 생산력의 감소, 실업의 증가, 채권자 및 주주의 부의 감소, 심리적 불안으로 인한 경제활동의 위축, 기업 노하우의 소멸, 대외적 신용도의 하락 등과 같은 사회적·경제적 파급효과는 대단히 크다. 이상과 같은 기업부실의 효과를 고려할 때 부실기업을 미리 예측하는 일종의 조기경보장치를 갖는다는 것은 중요한 일이다. 현금흐름정보를 이용하여 기업의 부실을 예측하면 기업의 부실징후를 파악하는데 그치지 않고 부실의 원인을 파악하고 이에 대한 대응 전략을 수립하며 그 결과를 측정하는데 활용될 수도 있다. 따라서 본 연구에서는 기업의 부도예측 정보 중 현금흐름정보를 통하여 '인터넷기업의 미래 현금흐름측정, 부도예측신호효과, 부실원인파악, 비즈니스 모델의 성격규정 등을 할 수 있는가'를 검증하려고 한다. 협력체계 확립, ${\circled}3$ 전문인력 확보 및 인력구성 조정, 그리고 ${\circled}4$ 방문보건사업의 강화 등이다., 대사(代謝)와 관계(關係)있음을 시사(示唆)해 주고 있다.ble nutrient (TDN) was highest in booting stage (59.7%); however no significant difference was found among other stages.

The amount of the milk clotting enzyme which is produced by Dothiorella ribis in wheat bran was 950 Soxhlet units per gram of wheat bran. The milk clotting activity of this enzyme was increased by the elevation of clotting temperature and by the increase of the addition of $CaCl_2$ to milk. It was also increased when the pH of milk was lower than that of the fresh milk. When milk was diluted by distilled water, the milk clotting activity of the enzyme was decreased. And its milk clotting activity was good when milk was pasteurized at low temperature. The enzyme of Dothiorella ribis has larger proteolytic activity per Soxhlet unit than that of the milk clotting enzyme of Mucor pusillus Lindt. This enzyme was rather stable between pH 6 and pH 8 when it was conditioned for ten minutes. The heat stability of enzyme was tested by treating it under the condition for $10{\sim}60$ minutes. And the enzyme was stable under the temperature of $45^{\circ}C$. Also the recovery of protein as a form of curd was 76.2 percent to the total protein content of milk.

This work was carried out to determine that ginseng cake (meal) could be substituted for 10% level of chicken feed. The feeding experiment was held with 180 laying hens for 8 weeks. And the results were as tin the followings, 1. Protein content of the ginseng cake was lower (4.25%) than that of the control feed (18.72%: commertial chicken feed), and crude fiber of the ginseng cake was higher (14.73%) than that of the control (9.39%). 2. Slight increasings of body weight were observed in the group of the control feed (10 g) and the group of the feed containing 10% of the ginseng meal (24 g), significant increasing (50 g) was seen in the group of the feed containing 5% of the ginseng meal (p<0.05). 3. The feed efficiency of the ginseng group was slightly higher than that of the control group, but significant defferences were not recognized. 4. Egg laying ratio of the 5% ginseng group was somewhat higher than that of the other groups, and egg weight of each group was almost same. With all the results of this experiments, it was identified that ginseng cake is able to be substituted for the feed of laying hen within 10% level.
