This study investigated the mate selection preferences of single female teachers by investigating the desired traits in socioeconomic, physical attractions, psychological traits and family roles of their prospected marital partner, in order to explore the current trends in homogamous marriage. A questionnaire was distributed to 295 unmarried female teachers selected by convenience sampling from the various cities. The teachers pursued homogeneity in age, educational attainment, religion, and occupation while they preferred partners with higher income level. In terms of physical assets, the attraction that the teachers felt towards the partner was the most important physical appearances. The respondents preferred partners who are masculine and an androgynous partner. The teachers held high expectations towards their future spouses in that they desired to share the roles of emotional, financial support, child care and kin keeping. A partner who shared modern sex role attitudes was preferred over someone who held traditional one. The pursuit for overall homogeneity reflects that the teachers seek for equality in their relationships with prospected marital partners by exchanging similar characteristic.

This study is attempt to submit a basic material to help the efficient nursing management which supports and to understand the alienation which they percieve social-psychologically and physical aging bringing about the phf·sical powerlessness, to understand the old people in hospitals and in community and should build up their health. The data collection of the study which has been done on Sept. 7 to Sept. 20, 1986 is objected to 300 people of 65 years old of age or more of male and female who are staying at home. Analysis of the Data was done by use of percentage, t-test, ANOVA and Pearson Correlation Coefficients. The results of study are summerized as follows: 1. According to each age group of old people(p= .0008), family living together concreteness (p=.0000), the level of education (p=.0020), how much they are participating in leisure activity (p=.0001), whether they have mate or not (p=.0000), whether they have religion or not (p=.0000), the level of alienation showed difference statistically. Also, according to sex (p=.4315), whether they have income or not (p=.1197), the level of alienation did not show any difference statistically. 2. According to each age group of old people (p=.0000), family living together concreteness (p=.0060), the level of education (p=.0000), sex (p=.0000), whether they have mate or not (p=.0000), whether they have religion or not (p=.0067), whether they have income or not (p=.0000), the level of physical aging showed difference statistically. Also, according to how much they are participating in leisure activity, the level of physical aging did not show any difference statistically (p=4879). 3. The level of alienation and physical aging in old people had positive correlation (r=.5436, p<.001). From the above result, the level of social, psychological alienation and physical aging showed high for the old who had no mate, no religion, low in their educational level, living separately' with the family and for those who do not participate much in the leisure activities, The old people who feel the social, psychological alienation can expedite the physical aging and physical aging can be result from social psychological loneliness and alienation. Therefore, for the successful aging of the old people in the community with these weak points, we should provide them with physical and emotional, psycho-logical support and care in the basis of understanding in socialization process and the character of the physical functional change.

To suggest a standard concerning with the arrangement of bridge equipment, the authors conducted the video observations with 3CCD (charge coupled device) cameras installed on the ceil of the bridge for monitoring the working activities of two bridge teams (the skipper/mate1 and the skipper/mate2) in a Korean coastal large trawler(gross tonnage: 139) for five days from July 30th. 2010 and analyzed of the data. Work elements coded by the work activities were input on the sheet of work analysis by the time unit of 1 sec according to the time occurred. A single work element among the work activities for every 5 minutes was denoted as the number of occurrence. The frequency of equipment usage was limited only in the usage of the equipment. In the case of the navigation and the towing net two ranks were integrated and analyzed. On the other hand, in the case of the casting net and the hauling net, two processes were integrated to as one and then analyzed separately as two ranks. As the results, 15 elements of work was carried out between two bridge teams for the observation; lookout, radar, GPS plotter, fish finder, net monitor, fishing deck, RPM indicator, rudder angle indicator, compass card, for maneuver; steering, ship speed control, trawl winch operation and external communications, paper works and others. It was found that the work load of the skipper per 5 minutes accordance with the navigation, the casting net, the towing net and the hauling net are 20.5 times, 11.9 times, 38.0 times and 9.5 times respectively, the mates are 65.2 times, 66.5 times, 85.7 times and 59.1 times respectively. The radar was shown the highest frequency of the equipment usage and the next was the fish finder, the GPS plotter and the external communications in the case of the navigation. In the case of the towing net the frequency of usage was high the ranking as the radar, the net monitor, the fish finder, the GPS plotter, the steering system and the external communications. In the case of the integrated process both of the casting and hauling net the trawl winch was shown the highest frequency to the skipper and the next was the GPS plotter and the radar, and the steering system was shown the highest frequency to the mate and the next was the radar, the ship speed control system, the GPS plotter, the net monitor and the fish finder.

Maras (Dolichotis patagonum) are monogamous and mate for life. A pregnant mara, 6.15 kg, died after forelimb amputation surgery at Seoul Zoo on February 28, 2009. In the bicornial uteri, two fetuses were found in each uterine horn. The placenta was chorioallantoic, hemochorial, discoidal and labyrinthic. The entrance of cervix had a deep fornix and no cervical folds were observed in the cervix. This report is the first about Patagonian mara and helpful for clinicians who deal currently or in the future with exotic pet animals.

In this paper, we study the timelike Bertrand curves in Minkowski 3-space. Since the principal normal vector of a timelike curve is spacelike, the Bertrand mate curve of this curve can be a timelike curve, a spacelike curve with spacelike principal normal or a Cartan null curve, respectively. Thus, by considering these three cases, we get the necessary and sufficient conditions for a timelike curve to be a Bertrand curve. Also we give the related examples.

Building a reliable mobile robot - one that can navigate without failures for long periods of time - requires that the uncertainty which results from control and sensing is bounded. This paper proposes a new mobile robot localization method using artificial landmarks. For a mobile robot localization, the proposed method uses a camera calibration(only extrinsic parameters). We use the FANUC arc mate to estimate the posture error, and the result shows that the position error is less than 1 cm and the orientation error less than 1 degrees.

The model of the shortest chemical bonds is applied for the classification of acentric simple and binary Mo(VI) and W(VI) oxides. It is shown that on the plane of the shortest chemical bonds the compounds are located into the rosette of three intersected ellipses. The correlation between the optical nonlinearity and combination of the bond lengths is discussed.

울산 삼산동 매립장 침출수의 수질정화 공정을 위해 새로운 여재인 AquaMate$^{(R)}$가 사용되었다. 본 실험에서는 AquaMat$^{(R)}$에 서식하고 있는 여러 미생물 중 우점종으로 여겨지는 3종의 미생물을 각각 분리하여 동정하였다. 이들 미생물은 그램 염색 결과 모두 간균 형태의 그램 음성으로 나타났으며, 각각 Agrobacterium radiobacter, Pseudomonas cepacia, Flavobacterium indologenes로 판명되었다. 이들,3종의 미생물은 모두 침출수에서는 잘 자라지 못하였으나 yeast extract같은 생장촉진물질의 존재 하에서는 침출수에서 빠른 생장속도를 보여주었다.
