With the advent of the 21th century, Korea surrounded by the three sides of the sea has been underlining the fact that it will become one of the strongest maritime powers near future as ever in the past. The study shows that in order to build up Korea as a powerful maritime country, not only should we urge its government to take more in-depth political interest in the field of the shipping industry, but the effective training and the managing program for sea-farers employing in th forefront of the shipping business(as the centric panel of the competent merchant marine officers) also have to be taken into a sufficient consideration. According to the large scale, higher speed and automatization of vessels, a number of seamen who have so well-workable brain as to dexterously operate the up-dated scientific equipments have come into be demanded. This study therefore has not only suggested that an improvement for the system of the education for merchant marine officers and the effective scheme of the management on them, but especially underlined the problems of seamen' and their families' economic and social securities as well.

It was well known that thermopile was quiet a competent sensor using to probe the temperature of "hot point" where the temperature can be off the temperature-limitation for normal operation of the main electrical power equipment. In the present work, we aimed for developing new Ge-thermopile materials which can be using a non-contact temperature sensors at various hot-point of the power equipment and evaluation of its output property. As a results of the present works, a new thermopile which were composed Ga-poded p-type and Sb-doped n-type in Ge-semiconductor were designed and manufactured by MBE(Molecular Beam Epitaxy) process and showed superior sensitivity at room temperature.

Maximum product of spacings estimator is proposed in this paper as a competent alternative of maximum likelihood estimator for the parameters of exponentiated-Weibull distribution, which does work even when the maximum likelihood estimator does not exist. In addition, a Bayes type estimator known as generalized maximum likelihood estimator is also obtained for both of the shape parameters of the aforesaid distribution. Though, the closed form solutions for these proposed estimators do not exist yet these can be obtained by simple appropriate numerical techniques. The relative performances of estimators are compared on the basis of their relative risk efficiencies obtained under symmetric and asymmetric losses. An example based on simulated data is considered for illustration.

This study was performed to develop the precise and rapid method to distinguish the blended sesame oil through the electronic nose analysis. The sesame oil was blended with corn oil at the ratio of 95:5, 90:10, 80:20(w/w), respectively. Samples were then analyzed by gas chromatography, SPME-GC/MS and the electronic nose composed of 12 metal oxide sensors. The sensetivities(delta Rgas/Rair) of sensors by electronic nose was carried out with principal component analysis(PCA). The proportion of first principal component showed 98.76%. In this study, the electronic nose analysis could be used as a competent method to classify for genuine sesame oil.

This research studied the social-emotional competence of children whose primary caregiver was a single-mother or single-father alone compared with children living with a single-parent but the primary caregiver was a non-parent (e.g. a grandparent). Subjects were 208 children (105 boys, 103 girls) from 10 elementary schools in 3 metropolitan cities. Instruments were the Adaptive Behavior Checklist constructed by the researcher, Self-esteem Inventory (Kim, 1987) and Emotional Competence Scale (Kim, 1998). Results showed that children in single-mother families were more social-emotionally competent than children in single-father families. Children whose primary caregivers were non-parents had higher self-esteem than children whose primary caregivers were single parents alone. There were interaction effects of caregiver variables on children's peer relationships and awareness/expression of their own emotion.

The intensive care unit (ICU) is the most common place to die. Also, ethical conflicts among stakeholders occur frequently in the ICU. Thus, ICU clinicians should be competent in all aspects for ethical decision-making. Major sources of conflicts are behavioral issues, such as verbal abuse or poor communication between physicians and nurses, and end-of-life care issues including a lack of respect for the patient's autonomy. The ethical conflicts are significantly associated with the job strain and burn-out syndrome of healthcare workers, and consequently, may threaten the quality of care. To improve the quality of care, handling ethical conflicts properly is emerging as a vital and more comprehensive area. The ICU physicians themselves need to be more sensitive to behavioral conflicts and enable shared decision making in end-of-life care. At the same time, the institutions and administrators should develop their processes to find and resolve common ethical problems in their ICUs.

Parents' marital conflicts are often linked to various emotional and behavioural difficulties of their children but rarely known about later adolescent and adult lives. This study was undertaken to examine if serious parental conflict such as divorce and/or separation in childhood was associated with emotional and social performance during later adolescent and adult lives. The research literature on divorce was briefly reviewed. The data was derived from the National Child Development Study (NCDSS 1974/age 16 - 1991/age 33) which followed the lives of 17,500 individuals born on March 3-9, 1958 in England, Scotland and Wales. Regression analyses indicate strong evidence that the experience of parental divorce or separation in childhood negatively affects the child's emotional and social performance in their subsequent life. The higher likelihood of having emotional problems, being less competent at their job, experiencing health/disability problems, being a lone-parent, unemployed, and homeless were strongly associated with parental divorce or separation experienced in childhood. Intervention is desirable to address the concerns influencing socio-psychological performance amongst children who have experienced parental divorce or separation.

Nowadays, the explosive evolvement of Internet. which is referred to as EC, has been prevailing. That has given the chance all of the world consumers to contact all of the world companies to enter into business relationship. But, electronic commerce laws have been established per conventional jurisdiction. some legal issues take place in the field of cross-border electronic commerce, including the governing law and competent courts. In this situations, it is gradually and widely required to lay down the internationally harmonized electronic commerce legal framework. Now, there are a lot of legal issues assumed in EC, in this study, we studied three precedence problems concerning B2C: Consumer Protection Law regarding B2C, Personal Information Protection Law in Private Sector regarding B2C, Web Site Trust Mark System.

The purpose of this study was to investigate the relationship between the quality of caregiver's behaviors and children's social behaviors. the quality of caregiver's behaviors were observed during indoor free-play time in the 8 classes at 7 child care centers. Forty children were selected from two classes of high quality caregivers and 2 of low quality caregivers based on the quality of caregiver's behaviors. Children's social behaviors were measured in terms of social competence, social maladjustment, and social interaction. results of the study were as follows: First, children of high quality caregivers were more socially competent than of low quality caregivers. second, there were no significant differences in social maladjustemnt according to the quality of caregiver's behavior. Third, children of high quality caregivers showed more positive and dependent interaction with caregivers high quality caregivers showed more positive and depedndent interaction with caregivers than of low quality teachers. Also, children of high quality caregivers engaged less in aimless behavior and negative interaction with peers than of low quality caregivers.

Addressing challenging behavior in young children with special needs is an important issue. This study analyzed the results of literature on parent-implemented behavioral interventions designed to manage the challenging behavior of children with developmental disabilities under 8 years of age. Seventeen relevant studies published in peer-reviewed English journals during the last 15 years were selected for review. The literature review showed that adequately trained parents can serve as a competent intervention agent, thereby making significant contributions to mitigating children's behavior problems. The reviewed studies also demonstrated that parents could play a variety of important roles such as informants and trainers in behavioral interventions. However, the conclusions on parent-implemented behavioral intervention may be tentative rather than conclusive due to previous research limitations including the lack of treatment integrity and social validity data. In addition, this review discussed several implications for practitioners, indicated the limitations of the reviewed studies, and presented suggestions for future research.
