The purpose of this research is to analyze the characteristics and problems of "Reading Cheongju" campaign which started as "One Book, One City" reading promotion campaign in 2006 and conducted three times in two years. The analysis of such steps as the selection and distribution of "one book", reading and discussion. events and programs, financial assistance, public relations, etc. documents both positive and negative aspects of its performance. "Reading Cheongju" campaign helped improve both the image of the Cheongju Information Library and the importance of reading and discussion in the community, while lacking in participation from diverse groups of community members, flexibility in spending public expenses, and cooperation among libraries and other related organizations.

Objectives: To determinate the optimal culture condition to maintain lifespan in human sperm, we evaluated the effect of different temperature on sperm motility and viability up to 5 days in normal specimens. Methods: Ejaculated semen samples with normal semen parameters were gently washed in HEPES buffered Tyrod's-Albumin-Lactate-Pyruvate (HTALP) media. Each 5 ml of HTALP + 0.3% albumin with $1{\times}10^6$ sperm/ml was incubated for 5 days in $37^{\circ}C$, $22^{\circ}C$, and $4^{\circ}C$. The sperm motility and kinematics were analyzed using computer assisted sperm analysis (CASA), membrane integrity was assessed by hypoosmotic swelling test (HOST), and capacitation status was evaluated by chlorotetracycline (CTC) fluorescence pattern. Each parameter was measured on day 1, 3, and 5, respectively. Results: The motility, viability and live/uncapacitated pattern were demonstrated significantly in temperature- and time-dependent difference (p<0.05). While the sperm cultured for 1 day in each temperature was not significantly different, the sperm cell kept in $22^{\circ}C$ after 3 days were preserved sperm motility, viability, membrane integrity, and F pattern better than in other culture temperatures. Conclusions: HTALP can be used a basic medium for culture and longevity preservation, and sperm cell kept at $22^{\circ}C$ is beneficial for assisted reproductive techniques.

In this paper, We investigated the characteristic analysis of flexibility and muscle strength for exercise to verify capacity in rehabilitation exercise of lumbar using lumbar strengthen exercise instrument. We have experiment in 20th years man and woman who are 20 subject with no medical history, we divided subjects into control group with no exercise and training group with lumbar strengthen exercise. We used Hi-Spine(Medicalscience.korea) also, provided exercise 40 minute a day, three days a week and progressed total four weeks. Moreover in our experiment, subjects exercised four postural position as lay down, sit, stand and stretch each ten minute. We measured trunk extension backward, trunk flexion forward, evaluation of based physical fitness and lumbar joint torque. The reults have shown that there more improved all for flexibility, based physical fitness and lumbar joint torque in training group than control group. We indicated that by rotating 3-D axis movement flatform of exercise instrument, muscle spindle in subject have been stimulated and these rotation direction and angle caused muscle tonus and contraction that makes muscle, flexibility and based physical fitness improve more. Our study can be used rehabilitation exercise program to aged people and patient with lumbar injury.

황천 운항 중인 선박은 파도에 의한 과도한 운동과 그로 인한 슬래밍, 프로펠러노출, 갑판침수와 같은 현상으로 구조, 화물, 인명에 위험을 초래할 수 있다. 이 때문에 황천 시 선박은 안전 운항을 위하여 속도와 코스를 신중히 결정할 필요가 있다. 선박 운동 모니터링 시스템은 해상환경이 선박에 미치는 다양한 위험 상황을 사전에 예측하고 피할 수 있도록 의사 결정을 지원하며, 현재 선박의 운동상태와 구조적 안정성을 지속적으로 모니터링 함으로써 선박, 선원, 화물의 안전을 지원할 수 있도록 개발되었다. 본 시스템은 주파수 영역에서 New strip 방법에 기초하여 운동 응답과 수직 굽힘 모멘트를 계산하며, 슬래밍, 프로펠러노출, 갑판침수를 예측한다. 또한 선박 운동과 선체구조응력을 실시간으로 모니터링하여 과도한 선체운동이나 선체구조피로 등의 위험 상황을 표시하고 선원의 작업성과 승선감의 지표인 MII (Motion induced interruption), MSI (Motion sickness incidence)를 제공한다.

The purpose of this study is to examine the effects of Psychomotor program on the child care teacher's ego resilience and childcare efficacy. The subjects of this study are childcare teachers of eight daycare centers in J-gu, Seoul. The final subjects were 18 in the experimental group and 19 in the control group. Psychomotor program was provided to the experimental group, which consisted of four hours per session, two sessions per week, and a total of ten sessions. Data collection took place between September 2 and November 12, 2017. Collected data were analyzed by independent sample Wilcoxon-Mann-Whitney test. In this study, the Psychomotor program had a significant effect on improving ego resilience and childcare efficiency of interpersonal relationships which is lower factor of the ego resilience. Through this study, we identified it was worth establishing a basic basis for managing and supporting ego resilience of child care teachers, and that it was meaningful to suggest ways to help them adapt and cope with their job duties.
