  • Deformability of RC members in shear after flexural yielding is limited and controlled by governing failure modes and material strength. Shear strength of members in D-regions has been explained by a direct load path (direct strut or arch action) and indirect load path (fan action or truss action). Indirect load path including truss action and fan action rely on bond along tension ties. Generally, superposition of two actions results in total shear strength when shear failure modes control. The ultimate deformation depends on controlling failure modes and thereby, their force transfer patterns. Proposed models are capable of explaining of limited deformability of RC members in D-regions.

  • Gymnodinium mikimotoi is one of several species of flagellates that cause harmful red tides. The red tides of G. mikimotoi have occurred only along $33-35^{\circ}$ N, e.g. Chinhae Bay in Korea, tile Seto Inland Sea and Kumane-Nada in Japan. I try to reproduce the formation of red ties of G. mikimotoi at Suo-Nada and Iyo-Nada, the western part of Seto Inland Sea, Japan in July 1985 with the use of four-dimensional assimilation model including the biological process of G. mikimotoi in this paper.

  • This study examines the influence of fashion accessories on how men of different ages are perceived, as well as how the social values of the perceiver affect the image evaluation process. For the purpose of this study, men's accessories were limited to glasses, ties, and hats. A quasi-experiment was conducted in which 358 female university students in Seoul examined two men, one in his 30s and the other in his 60s. The social value included materialism and hedonism with higher and lower group. Factor analysis revealed three main factors with regard to men's image based on age and accessories: professionalism, morality, and preference. The findings indicated that wearing accessories can affect how men are perceived, and the perceivers' social values are at play throughout the process. Glasses enhanced a professional image in men, while ties amplified professionalism and morality. Morality and preference for the older man were heightened when he wore a fedora and a hunting cap. Taking social values into account, perceivers with a higher level of materialism associated a man with a navy blue tie more strongly with professionalism. Perceivers who possessed more hedonistic traits preferred a man wearing a cap. The subjects considered the man in his 60s as having a higher level of professionalism when he wore casual hats such as a cap or a cloche. The results of this study suggest that social values such as materialism and hedonism play a part in how people perceive men wearing accessories.

  • The purpose of this study was to identify the producing process for Korean nursing knowledge as applied by Foucault's discourse analytic method. By Foucault's discourse analytic method, the problem is not what is knowledge but what sort of knowledge is made up through specific level of practice. A Korean body of nursing knowledge has been discussed since 1980. At the end of 19th century, missionaries transplanted western nursing knowledge and method to Korea. Western nursing knowledge and methods have been developed continuously with both merits and demerits to Korean society. Recently our world has be come a global community via advances in transportation and correspondence. Although each person is different in skin color and shape. there is a clear line between Oriental people and Western people. Nursing science is only one in our world. but western humanistic nursing practice based on western worldview and human life has limits. It is natural that the Koreans as Oriental people have a systemic nursing science to reveal the specific experiential and concrete body of nursing knowledge rooted in the Korean worldview and human life. Nursing science is to understand human beings, to promote health. to prevent illness. to restore health. to alleviate suffering and to search for principles needed throughout all of human life. In Korea, now is the quickening period to shape a Korean body of nursing knowledge because of a shortage of nursing language in matters of intellectual recognition, and unfamiliar practical nursing field where there is no familiarity in the system of nursing research methodology. In reviewing articles from the Journal of the Nurses' Academic Society on Korean body of nursing knowledge, it was found that there are two common features. The first, human body and mind are inseperable that is one unit in this world and health is keeping a harmonious relationship between human body and mind. The second, Korean nursing practice is based on human nature and family ties. Accordingly discourse analysis has a good future prospect to produce a Korean body of nursing knowledge for analytic research on body and mind monism and family centered care based on human nature and family ties.

  • The purpose of this study is to establish a relationship between TV home shopping model and the marketing data of the TV home shopping industry. Differences in relationship marketing factors, trust, and intent to reuse depending on the experience of the model have resulted in a higher assessment of both the expertise and service factors of fashion stylists than groups with 10 years or less experience. In addition, model groups with 15 or more broadcasts in one month rated the professionalism, communication, ties, trust, and intent to reuse fashion stabilists more than 15 model groups. The difference in marketing factors, services, communications and ties between the professional and use of home shopping models was found to be 40 years old as compared to those in their 20s and 30s. Finally, in terms of the gender of the home shopping model, the difference between the marketing factors and the reliability of the relationship and the intent to reuse, the professional, communication and bonding, trust, and re-purpose factors were all rated higher by the female group than the male group. The results of the study suggest that a relationship marketing strategy needs to be established between a fashion stylist and a TV home shopping model, and fashion stylists should be judged based on the characteristics of a TV home shopping model.

  • This study explores newborn clothing with regard to clothing type, construction, textiles, design, size, and label placement. Related consumer complaints are also analyzed. Analysis of 50 newborn clothing items revealed six types of newborn clothing: baenaet jeogori, baenaet gown, bodysuit, one-piece, shirt and pants set, and pants. The baenaet jeogori was the most common type, and the most commonly used fasteners were ties and snaps. The following characteristics were commonly observed: front opening, long raglan sleeves, mitten cuffs, cotton fabric, white/ivory color, animal print, contrast hem, $appliqu{\acute{e}}$, and size 60. In-depth interviews of 12 mothers with children under 24 months revealed that the baenaet jeogori was the most unsatisfactory type; the shirt and pants set and bodysuit were preferred. Interviewees were dissatisfied with types of openings, expressing a preference for snaps and complaining about ties, too many snaps, metal snaps, and shoulder openings. Overly wide or narrow sleeves resulted in improper fit, and long sleeves made it difficult to dress the baby. Interviewees required diverse sleeve length options. They were dissatisfied with heavy fabric for hot and warm seasons, and with labels attached inside clothing or outside near the neckline. Mothers with particularly small or big babies complained about limited sizes. To improve current newborn clothing, additional items such as shirt and pants sets or individual pants, front opening clothing with few snaps, proper sleeve fit with diverse length options, lightweight fabric for hot and warm seasons, label placement that avoids skin irritation, and size segmentation are recommended.

  • There has been increasing attention in many countries on seismic retrofit of old fashioned RC structures in recent years. In such buildings, the joints lack transverse reinforcement and suffer inadequate seismic dimensional requirements and the reinforcement is plain bar. The behavior of the joints is governed by sliding of steel bars and diagonal shear failure is less influential. Different methods to retrofit beam-column joints have been proposed in the literature such as wrapping the joint by FRP sheets, enlargement of the beam-column joint, and strengthening the joint by steel sheets. In this study, an enlargement technique that uses external prestressed cross ties with steel angles is examined. The technique has already been used for substructures reinforced by deformed bars and has advantages such as efficient enhancement of seismic capacity and lack of damage to the joint. Three reference specimens and two retrofitted units are tested under increasing lateral cyclic load in combination with two levels of axial load. The reference specimens showed relatively low shear strength of 0.150${\surd}$($f_c$) and 0.30${\surd}$($f_c$) for the exterior and interior joints, respectively. In addition, relatively brittle behavior was observed and large deformations extended into the panel zone of the joints. The retrofit method has increased ductility ratio of the interior beam-column joints by 63%, and energy dissipation capacity by 77%, relative to the control specimen; For external joints, these values were 11%, and 94%. The retrofit method has successfully relocated the plastic joints far from the column face. The retrofit method has improved shear strength of the joints by less than 10%.
