The study was to investigate kinematic difference between flexed and extended type of knee during Jigeo-Cha-Gi in Taekwon-Do. For this subjects participated were consisted of weights of fin (1), bantam (1) and welter class(1) of male 3 national representative level skilled in two type(flexed and extended type) of Jigeo-Cha-Gi. 3D cinematography analysis was performed for motion analysis and Kwon 3D ver. 3.1) was used for 3D coordinates & analysis variables calculation. In Temporal variable there was no significant difference statistically in all phases & total elapsed time between flexed and extended type, but flexed type was delayed more 0.016 sec than extended type. In displacement of COG there was significant difference in level of p<.05 showing longer mean 6.13 cm in case of flexed type than extended type in displacement of COG during all phase and too significant difference in level of p<.01 showing longer mean 4.4 cm in case of flexed type than extended type in displacement of COG in follow through phase. In velocity of COG there was significant difference in level of p<.001 showing higher mean 15.53cm/s in case of flexed type than extended type in velocity of COG(Y direction) during targeting phase and peak velocity(Y) was more fast 8.74 cm/s in extended type than flexed type. In velocity of leading leg in forward direction(Y) there was significant difference in level of p<.05 showing higher thigh mean value in case of flexed type than extended type but showing higher foot mean value in extended type at level of p<.001 than flexed type in velocity of COG(Y direction). In velocity of leading leg in vertical direction(Z) there was no significant difference in the second & third phase in case of vertical velocity level, but momentum transferred efficiently form proximal to distal endpoint. In front-back & right-left orientation angle of trunk there was possibility of more stable Jigeo-Cha-Gi in extended than flexed type by decreasing in right-left orientation angle of trunk. In relative angle of lower leg(hip, knee, ankle) there was significant difference in level of p<.001 showing longer mean 32.74 deg. in case of flexed type than extended type in hip joint during the second phase but maintained insufficient extended knee of mean 168 deg. in targeting phase.

The purpose of this study was to observe the tensile and bonding strength of the joined amalgam restoration. Amalgam alloys of fine-cut (F-type), spherical (S-type), and dispersed type (D-type) were selected in this study, and all specimens were divided into three groups according to the condensation methods as follows. Group I : the control group which condense the same kinds of mixed amalgam into the whole part of the mold respectively. Group II : the group which condense a mix of amalgam into one half of the mold, and then condense a new mix of amalgam into the rest half of the mold 15 minutes later. Group III : the group which condense a mixed amalgam into one half of the mold, and then condense a new mix of amalgam into the rest half of the mold 7 days later. All specimens were stored in incubator at $37{\pm}1^{\circ}C$ for seven days with immersing in saline solution before testing. The tensile and bonding strength of them were measured with Instron Universal Testing machine. The results were as follows: 1. In Group I, the order of tensile strength was F-type, S-type, and D-type. 2. In case of bonding of S-type + S-type, the difference of the bonding strength between Group II and III was not significant. (P> 0.05) 3. The bonding strength of F-type + S-type of Group II was marked the highest in value, and the lowest bonding strength was showed in bonded D-type + D-type of Group III. 4. In case of bonding with the different kinds of amalgam alloy in Group II, the specimen bonded to F-type was marked the highest bonding strength, and the specimen bonded with F-type was marked the lowest one. In Group II, the bonding strength of the specimens bonded with the same kinds of amalgam alloy was presented as the same order as that of Group I. 5. In Group III, the specimen connected with D-type marked the lowest bonding strength of all specimens. In Group III, the bonding strength of the specimens connected with the same kinds of amalgam alloy was the order of S-type + S-type, F-type + F-type, and D-type + D-type.

Coastal eupseongs, which are mainly built in the period of late Goryeo and early Joseon period, are essential materials in studying the history of Joseon period eupseongs. The purpose of this study is to connect the annexation of local districts with the relocation of local government office, so as to categorize the types of coastal-eupseongs and examine the background of their constructions and relocations. Coastal eupseongs are mainly divided into 'maintenance type' and 'Mergence type' according to the annexation of local districts, and maintenance type is broken down into fortress type and non-fortress type in accordance with the existence of old eupseongs(fortresses). Coastal eupseongs can also be categorized into 'application type' and 'relocation type' depending on whether ex-local government offices were reutilized or relocated. Maintenance type is 'fortress-application type'(Gimhae Gosung Old Ulsan-eupseong), 'non-fortress-application type'(New Ulsan-eupseong), 'fortress-relocation type'(Dongrae Kijang Geojegohyunseong Ulsan(Jwabyeongyoung)-eupseong), 'non-fortress-relocation type'(Sacheon Hadong Jinhae-eupseong Geojesadeongseong) are differentiated by type. Mergence type is divided into 'Merger of Villages after Castle Relocation Type(Changwon Namhae Gonyang-eupseong)', 'Merger of Villages before Castle Relacation Type(Ungcheon-eupseong)'. Coastal-eupseongs are moved to other places in need of more affluent water supply(Gimhae Gijang-eupseong) and wider usable area(Namhae Gohyunseong-eupseong). Eupseongs were enlarged owing to the population growth, caused by annexations of local districts.(Ungcheon-eupseong) 'Seonso'(navy yard) is a unique feature which cannot be seen in inland eupseongs.

This study was intended to provide women who are experiencing menopause with effective nursing care by exploring the menopause experience. The purpose of the research was to understand the subjective feelings of women about the question of what the menopause experience is. Q-Methodological method was used for that purpose. As the research method, Q-statements were collected preliminary to the study of through in -depth interviews and a literature review. For the study 34 Q-statements were selected. There were 21 women as subjects for the research. The 21 women sorted the 34 statements using the principle of Forced Normal Distribution. The principle of Forced Normal Distribution, which has nine scales to measure the individual opinions, was called Q-Factor Analysis by using PC Quanl Program to supply the material. As a result, there were four categories(self-com-passion type, self-regulation type, self-perception type, self-abandonment type) of special opinion about the menopause experience in these women. The first type was called Self-compassion This type' was associated with varying degrees of emotonal instability(psychological withdrawal). And type in menopause signifies loss of a socially valued status and may result in depressive symptoms. This type expresses the menopause experience as associated with negative reaction. The second type is called Self-regulation. This type overcomes the menopause experience more actively than the other types and do not express the menopause experience as one of suffering. This type make efforts by themselves to regulate the mono-pause experience. The third type is called Self-perception. This type perceives the experience of menopause which as typical menopausal syndrome (hot flashes and decreased vaginal lubrication, decreased estrogen producing atrophic changes of the labia and vaginal mucosa, making intercourse uncomfortable). The fourth type is called Self- abandonment. This type denies the experience of menopause. The meaning of menopausal experience is significantly related with a life accident or life load. Also, This type experiences pain in the musculoskeletal system. As a result, The meaning of the menopausal experience is affected by perceived subjective experience of the nurses, the need to understand each persons meaning of the menopause experience and to develop appropriate nursing interventions based on the typology of menopause experience. Finally. The result of the study will provide basic data for nursing intervention the menopausal women.

Background: This study was aimed to determine the optimal vine induction method for growing of Korean schisandra (Schisandra chinensis), by comparing plant growth and fruit yields between plants grown with either fence-type (U-type) or A-type induction. Methods and Results: Plants were transplanted on August 17, 2014, and the plant height, stem node number and weight were measured every two weeks, six times from June 17, 2016. The plant height, stem node number, and leaf length and width were higher with the A-type than with the U-type induction, by approximately 37.0%, 49.1%, 27.6%, and 12.7%, respectively. Although there was no significant difference between the photosynthesis rates of plants grown with the two vine induction method, the leaf area and leaf number per plant were higher in the plants grown with the A-type than the U-type, by approximately 23.7% and 46.0%, respectively. The number of green-color pixels, in a defined area of digital camera images of creeper leaves from the inducted vines, was significantly higher in the plants grown with the A-type than the U-type. The number of fruit clusters per plant was approximately 26 and 36, under the U-type and A-type, respectively. A two fold higher total fruit weight per plant was observed in the plants grown under the A-type (250 g/plant) than the U-type (120 g/plant). Conclusions: The A-type vine induction method is optimal for cultivation of Korean schisandra.

The study was designed to identify the attitude of nursing students to clinical education through Q-methodology. A C sample was developed through a review of the literature and interviews. Twenty - seven statements made up the finalized Q- sample. This was out of an initial 143 statements developed through consultation with eight professors. The P sample consisted of 25 nursing students in S Health Junior College.0 statements were written on seperate cards and were given to the 25 subjects to sort according to degree of agreement or disagreement. The Q-sorts by each subject were coded and analyzed with QUANL PC Program. The analysis discovered three major attitudes, namely “amicable adaptation” 〈type 1), “Nightingale social service” (type 2), and “realistic occupation pursuit” (type 3). The correlation was .465 between type 1 and type 2, .293 between type 1 and type 3, and .273 between type 2 and type 3. The characteristics of each type were as follows ; Type 1 (amicable adaptation) They satisfied in interpersonal relationships in the clinical setting. They would not dream of becoming Nightingale, but thought of nursing care affirmatively and performed their works faithfully and adapted themselves to the new circumstances easily, Fourteen subjects were classified as type 1. Type 2 (Nightingale: social service) They often dreamed as a child that they would be Nightingale with a white uniform and think that nursing is a gift from heaven. They have an aptitude for nursing care by nature and selected nursing science them-selves. They give care to the sick with pleasure. Seven subjects were classified as type 2. Type 3 (realistic occupation pursuit) They were not satisfied with their nursing practice. First of all they want a stable job, therefore they selected nursing science. They had conflicts in clinical practice, but were responsible for nursing and studied hard. Four subjects were classified as type 3. Through the results of this study, the attitude of nursing students to clinical education could be classified into three types. Therefore it is suggested that clinical education would be more valuable, if it was planned according to an understanding of the attitudes of nursing students to clinical education.
