Now we are faced on the national policy to aim at the nationwide logistics center in North-East Asia. To come true, Korean ports developments policies are better off going towards integrated governmental supportive system build-up, activated infra-structures, back-yard developments, legal and institutional system, international co-ordination networks system, customer-oriented port management system like one-stop services, and multi-variate financing resources. Above all, Related governmental institutions strongly have self-confidences and devotional efforts to make them all implemented not losing own way.

The purpose of this study was to investigate the educational needs of a mother when nurturing children from neonates to the schoolage. A total of 657 subjects responded to the survey about the level of educational needs when nurturing children. The subjects of the study constituted of 401 mothers who visited the health center for immunization and 256 mothers who visited the pediatric outpatient department or whose children were hospitalized in pediatrics. This instrument had 64 items about nurturing children from neonates to the schoolage and one item had a score range of one to four. In data analysis, SPSSWIN 9.0 program was utilized for descriptive statistics. The results were as follows. 1) Mothers who had the neonates represented the highest educational needs about parental-neonates attachments with 3.47 of mean score compared to neonatal convulsion(3.44), management of common colds(3.44), nutrition (3.44), fever control (3.42). 2) Mothers who had infancy represented the highest educational needs about management of common colds with 3.34 of mean score compared to psychosocial developments (3.23), management of foreign bodies (3.22), feeding the food(3.19), playing with the infant(3.16). 3) Mothers who had toddlers represented the highest educational needs about psychosocial developments with 3.35 of mean score compared to discipline for children(3.34), management of teeth (3.29), management of common colds (3.21), management of accidents(3.20). 4) Mothers who had the a child in preschool represented the highest educational needs about psychosocial developments with 3.53 of mean score compared to management of accidents(3.23), discipline for children (3.00). 5) Mothers who had the child in secondary school represented the highest educational needs about psychosocial developments with 3.42 of mean score compared to management of teeth(3.13), management of accidents (3.05).

The goals of developments in nuclear medicine instrumentation are to offer a higher-quality image and to aid diagnosis, prognosis assessment or treatment planning and monitoring. It is necessary for physicists and engineers to improve or design new instrumentation and techniques, and to implement, validate, and apply these new approaches in the practice of nuclear medicine. The researches in physical properties of detectors and crystal materials and advances in image analysis technology have improved quantitative and diagnostic accuracy of nuclear medicine images. This review article presents recent developments in nuclear medicine instrumentation, including scatter and attenuation correction, new detector technology, tomographic image reconstruction methods, 511 keV imaging, dual modality imaging device, small gamma camera, PET developments, image display and analysis methods.

이 연구는 사회정책의 결과는 사회성원들의 사회정책 선호를 집합적인 의사결정으로 전환하는 기제, 즉 정치제도의 차이와 관련된다는 이론모형을 경험적으로 검증하는 것을 목적으로 한다. 중위특성을 가진 사회성원이 사회정책을 선호한다고 하더라도 그러한 선호를 집합적으로 모으는 제도적 장치가 어떻게 작동하느냐에 따라 사회정책의 결과는 달라질 수 있다는 것이다. 분석결과 사회정책에 대한 직능제약 선호만 놓고 보면 일본과 한국은 조정시장경제로 분류되는 다른 국가들 못지않다. 하지만 일본과 한국은 조정시장경제나 자유시장경제로 분류되는 다른 국가들에 비해 민주주의 정치제도의 발전정도가 상대적으로 낙후되어 있으며, 노동인구를 표적집단으로 하는 사회정책 프로그램의 발전 정도 또한 낮다. 이러한 비교양상은 사회성원들의 선호를 집합적 의사 결정의 바탕으로 삼는 민주주의 정치제도의 낙후성이 사회성원들의 사회정책 선호와 실제 사회정책 발전 사이의 괴리라는 현상과 관련될 가능성을 보여준다. 한편 민주주의 정치제도가 어느 정도 발전해 있는 국가들 사이에서는 사회정책에 대한 사회성원들의 직능제약 선호의 차이 뿐 아니라, 선거규칙이라는 정치제도의 측면에서도 차이가 발견된다. 결국 16개 국가들의 종합적 양상은 사회성원들의 사회정책 선호와 그것을 집합적으로 모으는 정치제도, 그리고 실제 사회정책 발전 사이에는 밀접한 관계가 존재함을 보여준다.

기존의 항만개발방식은 관리청 주도하에 비관리청사업과 민간투자사업이 중심을 이루었다. 그러나 항만공사체제가 등장하면서 이들 상호간에 역할 및 기능분담체계를 명확히 정리하고 기존의 항만개발방식과 더불어 항만공사가 효율적으로 민간자본을 활용할 수 있는 방안을 모색해야 한다. 이에 따라 항만시설의 개발 및 관리 운영에 관한 업무의 전문성과 효율성을 제고하기 위하여 항만공사를 단일 창구로 하는 항만개발사업을 수행하고 항만개발방식의 시설공사를 항만공사로 이관하여 종합적인 관리기반을 구축하는 것이 필요하다. 이를 위하여 해양수산부가 민간자본활용 방식을 항만법과 민간투자법에 의한 방식으로 구분하듯이 항만공사가 항만법 원용방식과 민간투자법 원용방식을 통하여 민간자본을 활용한다면 항만공사는 독립채산제에 의한 운영이 가능하고 불필요한 절차 없이 항만시설을 소유할 수 있다. 또한 항만법 민자방식의 시설공사에서 해양수산부가 민간사업자에게 시달한 사업허가서를 실시협약으로 전환하고 민간투자법 민자방식의 시설공사에서는 실시협약의 당사자를 해양수산부에서 항만공사로 점진적으로 전환하는 것이 필요하다.

Alloy 600 having a superior resistance to a corrosion is used as a steam generator tubing in nuclear power plants. In spite of its high corrosion resistance, there are many tubings which experience corrosion problems such as a SCC under the high temperature and high pressure environments of nuclear power plants. The Alloy 600 tubing can be repaired by using a Ni electroplating having an excellent SCC resistance. In order to carry out a successful Ni electrodeposition inside a steam generator tubing, the effects of various parameters on the material properties of the electrodeposit should be elucidated. Hence this work deals with the effects of an applied current density, duty cycle($T_{on}/(T_{on}+T_{off})$) of a pulse current, bath temperature and solution pH on the material properties of Ni electrodeposit obtained from a Ni sulphamate bath by analyzing the current efficiency, potentiodynamic curve, hardness and stress-strain curve. Hardness, YS(yield strength) and TS(tensile strength) decreased whereas the elongation increased as the applied current density increased. This was thought to be by a concentration depletion at the interface of the electrodeposit/solution, and a fractional decrease of the hydrogen reduction reaction. As the duty cycle increased, the hardness, YS and TS decreased while the elongation increased. During an off time at a high duty cycle, the concentration depletion could not be recovered sufficiently enough to induce a coarse grain sized electrodeposit. With an increase of the solution temperature and pH, the YS and TS increased while the elongation decreased. The experimental results of the hardness and the stress-strain curves can be supplemented by the results of the potentiodynamic curve.

Due to the occasional occurrence of a localizedcorrosion such as a SCC and pitting in steam generator tubing(Alloy 600), leading to a significant economical loss, an effective repair technology is needed. For a successful electrodeposition inside a tube, many processes should be developed. Among these processes, an anode to be installed inside a tube, a degreasing condition to remove any dirt and grease, an activation condition for a surface oxide elimination, a strike layer forming condition which needs to be adhered tightly between an electroforming layer and a parent tube and a condition for an electroforming layer should be established. Through a combination of these various process condition parameters, the desired material properties can be acquired. Among these process parameters, various material properties including a mechanical property and its variation along with the height of the electrodeposit inside a tube as well as its thermal stability and SCC resistance should be assessed for an application in a plant. This work deals with the material properties of the Ni electrodeposits formed inside a tube by using the anode developed in this study such as the current efficiency, hardness, tensile property, thermal stability and SCC behavior of the electrodeposit in a 40wt% NaOH solution at $315^{\circ}C$. It was found that a variation of the material properties within the entire length of the electrodeposit was quite acceptable and the Ni electrodeposit showed an excellent SCC resistance.
