Wintering behavior of mallards Anas platyrhynchos was studied from November 1995 to February 1996 at wintering habitats : Seosan reclaimed site, Oksan reservoir, and Kum river in Korea. The population of wintering mallards in maximum count was about 35, 000 at Sosan, 500 at Oksan and 1, 680 at Kum river, respectively. In Seosan area, mallards spent more time on water surface. In Kum river and Oksan reservoir, however, they spent more time in riversides. During the daylight hours, mallards spent more time in riversides and ground as the time passes by in the area. Behavioral patterns varied with habitat type, by days and months. Resting was a major time expenditure of mallards on water surface and riversides, and feeding occured occasionally on the ground. During the daytime, feeding and resting activities increased as time passed toward dusks However, time spendings for locmotion and comfort were decreased when it is close to the sun sets. Major disturbance factors within the habitats were identified the local traffics of humans, boats, aircrafts and motor vehicles. Among them, human was the most frequently affecting disturbance factor to the wintering mallards.

Female genital morphology of Cryptocercus Kyebangensis is described, focusing on the structural features of ovipositors at each developmental stage. Ovipositor valves were the first genital structures to appear in female nymphs. The caudal margin of the 9th sternum was nearly straight in the 1st instars of both sexes, with a slight median notch, but was deeply concave in the female nymphs of the End instar. The 1st valve of ovipositor budded off from membranous fold between the 8th 8nd 9th sternum and a pair of the 2nd valve came from the 9th sternum. Separation of styli occurred in the female nymphs of the 8th or 9th instar. Some parts of the female genitalia were sclerotized after the final molt. Spermathecae were the fork type and leaned a little to the right in the middle line of the genital chamber from ventro-posterior view. The trace sealed with sclerite materials existed on the spermathecal opening. The genital segments (segments Ⅷ, IX, and X) were concealed completely by the 7th tergum and sternum posteriorly expanded. Terminal lobes which exist in the Blattidae were not observed in C. Kyebangensis. Instead, the apicolateral emargination existed on the terminal abdominal segment of C. Kyebangensis females.

The purpose of this study was to investigate the relationships among the variables of attitudes toward school uniform, three aspects of clothing behavior, self-concept, and selected behaviors. Instruments used to test the hypotheses were 12 items selected from the Behavior Test by Laubach, The Perceptual Orientation Scale by Choi, 14 items to assess the attitudes toward school uniform, and 21 modified items to evaluate conformity, fashion, and modesty in clothing. The questionnaires were completed by 484 2nd grade junior and senior high school girls in Seoul. Statistical analysis was performed using the correlation coefficient, $x^2$-tests, and t-tests. The findings could be summarized as follows: 1) Perceptual Orientation and Behavioral Orientation were not significantly related to attitudes toward school uniform. 2) Perceptual Orientation and Behavioral Orientation were negatively related to clothing conformity, 3) Attitudes toward school uniform and clothing behavior were partially different by the grade level and the type of school. 4) Fashion was positively related to conformity, but negatively related to modesty in clothing.

This research was conducted to examine coffee shop customers' preference and satisfaction by different types of promotion. Research samples ware adults with experience of any form of coffee shop promotion (n=209). Descriptive statistics, Chi-square, t-test and one-way ANOVA were used to analyze the relations among variables. Results showed that 'free coupon' was the most preferred ones. SNS was the most frequently used search method for coffee shop coupon promotion information. The most preferred event promotion was 'freebies', and preference levels were significantly different by age and employment status. 'Barista experience' was ranked highest in preference among cultural experience events. Drinking coffee was the most important purpose of visiting coffee shops, especially among unemployed, twenties, and women respondents. Coupon was evaluated the highest in usefulness and satisfaction among the three promotion methods. Event and cultural experience were preferred more by respondents in their twenties than those in their thirties. Results indicated that all promotion strategies are effective for increasing customer satisfaction and for inducing revisit. Findings also showed that preference for promotion was affected by customer characteristics such as age and gender. Therefore, coffee shops should consider using the most effective and attractive promotion strategy for their target market, while maintaining a consistent service quality level to fulfill customer expectation.

Premature ejaculation is the most common sexual dysfunction seen in the male, and it is found in 30 to 50% adult male population. It is defined as the inability to control the ejaculatory process for a sufficient length of time during intravaginal containment to satisfy his partner in at least fifty percent of his coital connections The majority of men with premature ejaculation have underlying psychologic origin of performance-anxiety type, but it is not always psychogenic and may also be a presenting symptom in certain organic disorders. In oriental medicine, the point of treatment of premature ejaculation is recovery of the good ejaculatory control, and the treatment can be approached in three ways as psychological therapy involving behavioral therapy, herb drugs, and acupuncture. This study has aims to investigate and summarize the current trend of treatment for premature ejaculation so as to suggest the effective and available way to treat the disease.

Though super-highrise apartment buildings have become increasingly widespread, their negative effects on the residents have not been investigated sufficiently and practically in domestic situations. In particular, the foreign discussion on residential environment and the residents' health can not be applied domestically due to physical or cultural differences including physical residential space structure and life-style. Therefore, this research aims to investigate the inter-relationship between residence in super-highrise apartments and their residents' health, to reveal the problems which exist. for this purpose, a parental-response health evaluation - questionnaire on children's physical, emotional and behavioral characteristics was given to a total of 336 persons. The health of the children living in super-highrise apartments is evaluated to be good, and is related to what floor of the apartment building people live on. It is represented that the higher the story, the better the children's health. However, there is no meaningful difference according to various evaluation items including the frequency and type of disease, emotional health, behavioral characteristics, etc. Therefore, it cannot be said that children's health shows no meaningful differences depending on what floor they live on. The parents dwelling on higher floors of the building display a more careful educational attitude. This is because they feel anxious about the children's safety as shown by the fact they live on higher stories.

Numerous experimental studies have been conducted on reinforced concrete (RC) beams strengthened in shear with externally bonded fiber reinforced polymer (EBFRP). The objectives of this work are to study the behavioral trends of shear strengthened EBFRP RC beams after updating the existing database. The previously published databases have been updated, enriched and cross checked for completeness, redundancy and consistency. The updated database now contains data on 698 EBFRP beams and covers the time span from 1992 to 2018. The collected database then refined applying certain filters and used to investigate and capture better interactions among various influencing parameters affecting the shear strength of EBFRP beams. These parameters include the type and properties of FRP, fiber orientation as well as the strengthening scheme, the shear and the longitudinal steel reinforcement ratios, the shear span ratio, and the geometry of the member. The refined database is used to test the prediction accuracy of the existing design models. Considerable scatters are found in the results of all tested prediction models and in many occasions the predictions are unsafe. To better understand the shear behavior of the EBFRP RC beams and then enhance the prediction models, it was concluded that focused experimental programs should be carried out.

The bed nucleus of the stria terminalis (BNST)-a key part of the extended amygdala-has been implicated in the regulation of diverse behavioral states, ranging from anxiety and reward processing to feeding behavior. Among the host of distinct types of neurons within the BNST, recent investigations employing cell type- and projection-specific circuit dissection techniques (such as optogenetics, chemogenetics, deep-brain calcium imaging, and the genetic and viral methods for targeting specific types of cells) have highlighted the key roles of glutamatergic and GABAergic neurons and their axonal projections. As anticipated from their primary roles in excitatory and inhibitory neurotransmission, these studies established that the glutamatergic and GABAergic subpopulations of the BNST oppositely regulate diverse behavioral states. At the same time, these studies have also revealed unexpected functional specificity and heterogeneity within each subpopulation. In this Minireview, we introduce the body of studies that investigated the function of glutamatergic and GABAergic BNST neurons and their circuits. We also discuss unresolved questions and future directions for a more complete understanding of the cellular diversity and functional heterogeneity within the BNST.

This paper discusses issues faced by individual building industry clients. These form the majority of clients but, because they do not possess high purchasing power, they attract less attention in the industry. Given that key decisions on project definition and procurement strategy are made at the pre-project stage, the industry would benefit from knowing relevant aspects of its clients' attitudes and behaviors, so that it can support them. There is a lack of research on this subject, and so we first describe a theoretical framework and research methodology that were developed for this specific group of clients. Theory adopted from consumer behavioral research was introduced to develop a general behavioral model of individual clients. In this model, individual clients are assumed to seek and then process information after acknowledging normative activities. To validate our model, a field survey was conducted using randomly selected individual clients. Their opinions on the importance and difficulty of 12 normative activities were analysed to establish a general attitude. Information seeking behaviour was investigated by measuring the frequency and type of source that they contacted to conduct the normative activities. The attitudes and information seeking behaviour presented in this research will contribute to the development of project tools for supporting these clients.
