The term "P2 sir-associated helper inefficiency" has been used to define the inefficient helper capability of P2 sir mutants for their satellite bacteriophage P4. The aim of this study was to investigate the factors overcoming P2 sir-associated helper inefficiency. At first, we verified whether the P2 cos region containing P4 sid71 cosP2 could overcome P2 sir-associated helper inefficiency with P2 sir3. The result was that P4 sid71 cosP2 could not overcome P2 sir-associated helper inefficiency with P2 sir3. Instead of cos region of P2, the size of the DNA packaged into a $P2_{sir}$-sized head seems to be important for overcoming P2 sir-associated helper inefficiency. In the present work, three kinds of P4 derivatives with packaged DNA sizes between those of P4 ost1 and P4 ost2, were constructed through DNA manipulation. In one P4 derivative, P4 sid71 delRI::apr, the size of the packaged DNA was identified with a CsCl buoyant equilibrium density gradient experiment. According to the burst sizes of the P4 derivatives, they could overcome P2 sir3-associated helper inefficiency. The size of the P4 derivative DNA suitable for packaging into a $P2_{sir3}$-sized head was 28-29 kb.

The present study focused on frustration emotion investigated the variables evoking frustration and the process in which sense of frustration would be overcome, and explored the principle of aesthetics the consumers under the frustration might prefer in choosing goods. The results of this study are as follows. First, consumers usually felt frustration rather than anger when it became obvious that their objectives could not be met and that they failed to achieve their objectives due to uncontrollable cause. Second, consumers who felt frustration wanted to receive emotional support and comfort from close acquaintances rather than to cope actively with the unsuccessful situation by renewed challenges. Third, consumers, once frustrated, preferred harmony principle rather than emphasis principle in terms of esthetics in choosing design of goods. Therefore, marketing managers are advised to approach to the consumers who felt frustration on the basis of harmony principle in design of goods.

The purpose of this study was to develop psychological skill training program for actor with considering the ecological validity of social, cultural environment in Korean but also examine the effect of psychological skill training through psychological counseling and field study to decrease stage-anxiety. The experimental group were 2 actors, who were selected by purposive sampling. The psychological skill training program to decrease stage-anxiety for actor was composed of five stages, 12times and categorized as orientation, breathing regulation, progressive relaxation training, group counseling, heart rate bio-feedback training, self concentration, routine training, behavior therapy & self reinforcement, image training. The effects was examined on stage performance anxiety scale, psychological counseling and observation of experts. As the result of applying the psychological skill training to decrease stage-anxiety, cognitive state anxiety, somatic state anxiety were decreased. According to the result of counseling and observation, they were changed affirmative on self confrontation, harmony and rapport between actor and object. This result demonstrated the psychological skill training & counseling to decrease stage-anxiety for actor were effective.

The research was to identify difference of values of the self-esteem, resilience and quality of life of hemodialysis patients. The survey was conducted to collect data between February 1 and 28 of 2020. SPSS/WIN 20 program was used to perform descriptive, correlation, and multiple regression analyses. In the correlation analysis, Cohabitation form(r=.262, p<.01), Economic status(r=.278, p<.01), Current health status recognition(r=.294, p<.01), Self-esteem(r=.547, p<.01), Resilience(r=637, p<.01) turned out to be influential factor for self-esteem, resilience, and quality of life according to general and disease of characteristics. Therefore, on the basis of this research, it is meaningful to provide basic data for the development of nursing interventions that allow one to embrace one's health condition and find the meaning of life in order to improve the quality of life of hemodialysis patients.

디지털기술의 발달로 인하여 통신 ${\cdot}$ 방송 ${\cdot}$ 정보기기의 융합의 확산은 관련 기업들로 하여금 향후시장을 석권할 다양한 디지털 컨버전스 제품을 경쟁자보다 먼저 개발함으로써 주도권을 확보하기 위한 치열한 경쟁을 전개하게하고 있다. 그러나 많은 디지털 컨버전스 제품들은 캐즘을 넘어 주류시장에 성공적으로 진입하지 못하고 시장에서 조기에 사라져 버리는 실패를 경험하고 있다. 이에 본 연구는 컨버전스 제품의 개념과 특성을 바탕으로 디지털 컨버전스 제품의 확산에 영향을 줄 소비자의 구매영향 요인들을 도출하고, 이들 디지털 컨버전스 제품의 구매영향 요인들이 소비자의 혁신성에 따라 어떤 차이를 보이고 있는가를 검정하여 디지털 컨버전스 제품이 캐즘을 극복하여 효과적으로 확산되게 하기 위한 전략적 시사점을 도출하고자 한다.

물류산업 분야에서 EDI를 도입하기 위한 노력이 해양수산부와 항만 운영회사를 중 심으로 지속적으로 이루어지고 있다. 이러한 노력에도 불구하고 우리 나라 물류 ED 시스템 은 종이 서류를 전자 서류로 대신하는 시스템 구조를 채택하고 있기 때문에 이 문제를 극복 할 수 있는 새로운 시스템의 출현이 요구된다 하겠다. 본 논문은 우리 나라에 도입되어 운 영되고 있는 물류 EDI 시스템이 보다 한 차원 높게 발전하기 위해 요구되는 시스템의 성공 요인을 제시하는데 있다. 국가 또는 항만 단위의 물류정보 시스템이 보다 효율적으로 운영 되기 위해서는 단순한 전자 문서 전송방식보다는 데이터의 공동 이용 방식을 채택하는 시스 템으로 전환되어야 한다. 그 이유는 항만을 중심으로 전송되는 물류 데이터는 그 특성상 약 간의 수정을 거쳐 반복적으로 물류 조직 사이에 전달되기 때문이다. 본 연구를 위해 독일, 프랑스, 영국, 미국, 일본 등 발전된 물류정보 시스템이 검토되며, 아울러 KL-Net이라 불리 우는 우리 나라 물류정보 시스템의 고찰이 이루어지고 있다. 선진화된 항만의 물류정보 시 스템으로부터 시스템의 성공 요인이 도출되며 이 시스템을 실현하는데 경험하게 될 몇 가지 어려운 점이 논의되고 있다.

The objective of this study is to describe and determine how and to what extent size of firm, operating vessels and interest cost, leverage, debit maturity, growth opportunity and cash flow affect the cash holdings of Korean shipping companies. A sample of 38 Korean shipping firms for a period of 9 years(from 2005 to 2013) was selected. In panel data regression, this study finds that cash holdings are negatively affected by firm size, operating vessel size and debit maturity, and positively affected by volume of interest costs. In firm's group of relatively large volume of operating vessel, it's cash holdings are affected by debit maturity, cash flows and growth opportunity but in firm's group of small volume of it, interest cost, debit maturity and operating vessel's size are related with cash holdings. It proved that determinants of cash holdings in a high interest costing group are size of operating vessel, interest cost and debt maturity. On the other hand, debit maturity, growth opportunity, firm size and extent volume of vessels are associated with cash holdings in relatively row interest costing group.
