근거리 소출력 무선통신이 가능한 ZigBee 기술을 이용하여 다자간 자동 명함 교환 시스템을 구성하였다. 모든 노드가 서로 교대로 정보를 교환하는 full mesh network의 특성을 갖는 다자간 자동 명함 교환 시스템에서 정보교환에 소요되는 시간을 줄이는 것이 필요하다. 본 논문에서는 먼저 CSMA/CA 방식으로 주고받아 저장된 노드들의 주소 정보를 방송 후 각 노드들은 FIFO에 기반한 노드 순서에 따라 명함정보를 순차적으로 다른 노드들에게 방송한 방법을 제안하였다. 제안한 방식의 소모 시간을 분석하고 CSMA/CA 방식으로 직접 정보를 주고받는 방식과 비교하여, 노드 수와 정보량이 증가함에 따라 제안한 방식의 시간 소모가 직접 정보를 주고받는 방식보다 적음을 알 수 있었다. Autonomous business card exchange system using ZigBee with low power and short range was configured In the autonomous business card exchange system characterized as full mesh network in which every node exchanges each information one by one, it is necessary to reduce the time taken for information to be exchanged. In this paper, the novel method where the node ID is exchanged based on CSMA/CA and then the information of each node is broadcast to other nodes according to the ID list based on FIFO. The time required for exchanging information using the proposed method was analyzed and compared with the direct exchange method based on CSMA/CA. The results show that it takes less time in the proposed method than the direct exchange time.

The distribution of the causes was Slip-down 17 cases(53.2%) the most. 3. The distribution of the period before admission was within a week 19 cases(59.4%) the most. 4. The distribution of treatment duration in descending order: Under a week and two weeks under four weeks was the most number in 11 cases(59.4%) each. 5. The distribution of the injured level was L1 body 15 cases(18.3%) the most. 6. In the distribution of grading clinical severity on admission, the most cases were Gr.IV(18cases, 56.3%). 7. In the distribution of clinical symptoms on admission, 30 patients(21.9%) complained lower back pain and disturbance in turning over. 8. In the distribution of treatment result, the most cases(18 cases, 56.3%) was good. 9. The distribution of treatment duration according to the clinical grade on admission was as follows: Two weeks under four weeks was the most number in 8 cases(25%) in the group of Gr.IV, under two weeks was the most number in 6 cases(18.7%) in the group of Gr.III, and under four weeks was the most number in 2 cases(6.2%) in the group of Gr.II. 10. The distribution of treatment result according to the clinical grade on admission was as follows: Good was the most number in 10 cases(31.2%) in the group of Gr.IV, 6 cases(10.7%) in the group of Gr.III and 2 cases(6.2%) in the group of Gr.II. 11. The distribution of treatment result according to the treatment duration was as follows: Good was the most number in 4 cases(12.5%) under two weeks, 6cases(18.7%) two weeks under four weeks, and 6 cases(18.7%) four weeks under six weeks.

Human seminal fiuid (HSP) hypersensitivity is rare, but possibly a life-threatening disease. The pathogenesis of seminal plasma hypersensitivity and the exact nature of the HSP allergens remains to be clarified. We report a case of 25-year-old female patient who complained of severe itching sensation, flushing and edema of external genitalia, facial edema and dyspnea after sexual intercourse. The diagnosis was established by skin pr ick test with her husbands diluted semen. Intravaginal desensitization was performed by modified Matloffs method. Dilutions was made with sterile human serum albumin(0.2%) and 0.4% pheno1-0.9% saline solution. Two ml each of progressively greater concentrations of semen dilutions(1: 100,000 v/v, 1: 10,000 v/ v, 1:1,000 v/v, 1:100 v/v, 1:10 v/v) were inserted intravaginally at 45-min intervals, followed by an undiluted specimen. The patient was successfully desensitized and could have unprotected intercourse without anaphylaxis.

The purpose of this study was to identify the relations between the Effect of the factors of watching the pro football game by Female Spectators on the satisfaction of watching the game and the re-watching and the relation of each characteristics. Survey was conducted from 300 Female Spectators in games of pro football teams, The data from this study were analyzed using Confirmatory factor analysis, Correlation relative analysis, Multiple regression analysis. Results of this study were as following. First, the result of correlation Analysis for the factors of watching the game, the satisfaction of watching and the re-watching, the socio·psychology, the player·team, the game related, the factors of marketing were showing the correlation of statistically attentive plus(+) in the relations between the factors of watching the game and the satisfaction of watching, socio·psychology, the game related, the satisfaction of watching were showing the statistically attentive plus(+) in the re-watching. Second, the factors of socio·psychology, the game related, the factors of marketing are showing the plus(+) Effect on the satisfaction of watching, the factors of facility·environment, the leisures are showing the minus(-) Effecton the satisfaction of watching. Third, the socio·psychology, the game related factors is showing the plus(+) influence on the re-watching, the facility·environment factors is showing the minus(-) influence on the re-watching. Forth, the satisfaction of watching the game is showing the plus(+) Effect on the re-watching, this suggests that the satisfaction is affecting the most substantially on the re-watching.
