Officers and ratings as a group might show differences in some aspects of personality , human relations, job attitudes, perception of business environment and surrounding organizational structure. It has been traditionally believed that licenced-officers are required to have nicely-paired leadership and dignity , and ratings obedience in maritime field. This survey revealed that officers and ratings have some differences in the actual behavior, knowledge , understanding attitude etc., In summary , officers as a superstructure of merchant ship's orgnaization are different, to some degree, from ratings as an infrastructure in several aspects. Officers are believed to have the characteristics of maturity by taking concern of business environment , social circumstance away from the vessels which they are on board. In contrast, ratings are greatly interested in the surrounding environment associated with themselves, and also experiencing alienation and technology.

We study the solution of truncated series of Lee Sang-hyeog with the aspect of visualization. Lee Sang-hyeog solved a problem of truncated series by 4 ways: Shen Kuo' series method, splitting method, difference sequence method, and Ban Chu Cha method. As the structure and solution of truncated series in tertiary number is already clarified with algebraic symbols in some previous research, we express and explain it by visual representation. The explanation and proof of algebraic symbols about truncated series is clear in mathematical aspects; however, it has a lot of difficulties in the aspects of understanding. In other words, it is more effective in the educational situations to provide algebraic symbols after the intuitive understanding of structure and solution of truncated series with visual representation.

Theoretical and practical aspects are investigated for electrochemical behavious, plating processes and the structures of electrodeposit of Pb-Sn binary alloy plating through numerous literatures in this report. The anodic and cathodic electrode reaction mechanisms of Pb and Sn could co-deposit and make Pb-Sn alloy deposit from the results of cathode current density-cathode potential curves of Pb, Sn and Pb-Sn alloys in fluoborate solutions. The compositions of the best alloy plating solutions are obtained for the purpose of bearing, anticorrosion and solder plating. In general, the casting anodes of Pb-Sn alloys are used, but separated anodes of Pb and Sn pure metal are used in order to obtain the fine compositions of Pb-Sn alloy deposits. The electrodeposits of Pb-Sn alloy are in nonequilibrium state and saturated solid solutions. Thus, ${\beta}$-phase (Sn-phase) is precipitated by heat treatment. The texture and structure of the electrodeposit are associated with the surface energies of deposit lattice planes and with the cathode polarization. The electrodeposit of Pb-Sn alloy is shown as lamellar structure.

To be a good architecture, resident' needs should be defined as possible as definitely. A Multi-family housing is not easy to define of resident' needs, because the user is ambiguous and the needs is multi aspects. Byker housing project have a good approach to define ambiguous and many aspects of residence' need. In this view points, Byker redvelopment project show the process of resident' participation as a new customers, and design process architect with people, in spite of the early 1970s' project in terms of the user participations. This approach of residence participation is a good lesson how to communicate with recidence, how to identify the need, and its design is satisfied in the residence. And its project are discussed with residence how to manage of rehabilitation.

The kinetic façade system is an interactive building envelope which is adaptive to environmental condition by transforming the behaviour of its components. The design process of kinetic façade system calls for a novel approach. It needs to support designers to adopt technologies from multidisciplinary fields such as physical computing and robotics. In this paper, prototyping method is introduced as a useful technique for implementing kinetic façade systems. In order to incorporate prototyping method into architectural design process, two aspects are investigated in digital design studio: (1) The interactions between digital and analogue environments (2) The role of traditional design tools. Furthermore, the role of BIM is investigated by analyzing two aspects.

This study is intended to develop a scale to measure familism. Construction of this scale is based on a sample of 448 married males and females living in Seoul. This scale to measure familism is developed by employing a type of item analysis method called correlation analysis. 13 items are selected by correlation analysis, and these are found statistically significant even by analysis based on the criterion of internal consistency. Validity of this scale is evidenced by logical validation, jury opinion and independent criteria. Reliability estimate assessed by Cronbach's alpha coefficients is .759. This scale comprises the following 4 aspects of familism: 1) Support for filial piety and ancestor worship. 2) Integration of individual activities into family ones for achievement of family objectives. 3) Obligation to support individual family members and give them financial assistance when needed, on the assumption that properties such as land, money, etc. belong to family. 4) Mutual aid in psychological and social aspects between parents and married children, and married children and their married siblings. It is concluded that this familism scale represents an improvement on other measure of familism, but that a number of methodological issues remain to be further studied.

Advertising is the most powerful marketing communication tool. Fashion magazines are a popular media for fashion advertising because of their multi-color visual printing. In this study, the interest in and attitude toward fashion advertising were investigated with high school girls in Seoul, along with their interrelation with buying experience and post-purchase satisfaction. The consciousness of the endorser and the fashion of celebrities both increased with rising interest in fashion advertisement. However, the brand orientation showed no relationship with the interest in fashion advertisement. The interest in fashion advertisement was useful to explain buying experience with limited variance. The correlation between brand orientation and buying experience increased with rising interest in fashion advertisement, indicating that those with little interest in fashion advertisement showed strong dependence on brand loyalty. Those with more interest in fashion advertisement counted distinctive aspects of fashion advertisement more seriously. Affective aspects of fashion advertisement showed a correlation with buying experience and post-purchase satisfaction.

There is increasing interest in the many beneficial aspects of green tea to human such as anti-carcinogenic, anti-aggregant, anti-allergic, anti-bacterial, anti-mutagenic, and anti-oxidant activities. Besides these beneficial aspects, it has been reported that green tea ingredients, especially polyphenolic families (i.e., catechin), have some UV protection property both in vivo and in topical applications. In this study, green tea extract was used as a dyeing stock for cotton and the UV protection property of the dyed cotton fabric was examined. To increase the affinity of cotton fiber to the polyphenolic components in the green tea extract, a natural biopolymer, chitosan, was used as mordanting agent. The effects of chitosan concentration in mordanting on the dyeing characteristics and the UV protection property were examined. Chitosan mordanted green tea dyed cotton showed better dyeing characteristic and higher UV protection property compared with the unmordanted green tea dyed cotton. As the chitosan concentration in mordanting increased, the dyeing efficiency and the UV protection property also increased. Therefore, adapting chitosan mordanting in green tea dyeing can increase the UV protection property of cotton fabrics to some extent.

Human beings can perceive various aspects of sound including loudness, pitch, length, and timber. Recently many studies were conducted to clarify complex auditory scales of the human ear. This study critically reviews some of these scales (decibel, sone, phon for loudness perception; mel and bark for pitch) and proposes to apply the scales to normalize acoustic correlates of human speech. One of the most important aspects of human auditory perception is the nonlinearity which should be incorporated into the linear speech analysis and synthesis system. Further studies using more sophisticated equipment are desirable to refine these scales, through the analysis of human auditory perception of complex tones or speech. This will lead scientists to develop better speech recognition and synthesis devices.

Apartments recently built have been strategically designed in many ways, and one of the most striking aspects is to utilize the idea of environmental friendliness and the application to the living environment. Especially, the number of environmentally friendly apartments that concern the health of residents have been increasing and their landscape is notably differentiated. The purpose of this research study was to examine the landscape of the environmentally friendly apartments that have been built in the past five years, and to assess its features in the aspects of therapeutic garden. Based upon the review of previous studies, this study constructed a checklist that was used to evaluate the planning components of the landscape during site visits. This study found that overall landscape selected in the study was well-planned. However, it was suggested that more features of therapeutic garden such as vegetation area which both encourages interaction with residents and produces therapeutic benefits be adopted in planning the advanced therapeutic garden of environmentally friendly apartments.
