포유동물에 있어서 조기 성 판정기술은 축산에 있어서의 성별 육종프로그램이나 인간의 X-염색체 관련 열성유전병의 산전진단 등 여러 분야에 응용될 수 있다. 초기배에 대한 성 판정은 성염색체에 존재하는 특이한 염기서열을 증폭시키는 polymerase chain reaction (PCR)과 X와 Y 염색체에 대한 특이적 probe를 이용하는 fluorescent in situ hybridization (FISH)에 의하여 수행될 수 있다. 1992년과 93년, 2개년도에 걸쳐 본 연구실에서 돼지의 3.3 kb 웅성특이 DNA 절편(pEM39)을 cloning하였다. 본 연구는 pEM39가 성특이 DNA-probe로 이용될 수 있는지를 조사하기 위해 PCR과 FISH를 이용하였다. 돼지 난자는 도축장에서 구입한 돼지 난소로부터 채취되었고, 체외배양후 체외수정되었다. 한편 처녀발생나자를 negative control로 이용하였다. 2 세포기의 수정란을 선발한 후 PCR을 통하여 DNA를 분석한 결과, 10개의 수정란 중 6개는 자성, 다른 4개는 웅성으로 판정되었으며, FISH를 수행한 결과, done된 웅성특이 DNA 단편은 돼지 간조직과 초기배에서 웅성특이성을 보였다. 또한 FISH와 karyotyping을 수행한 결과 clone된 웅성특이 DNA 단편이 Y 염색체 q-arm의 heterochromatic region에 위치함을 알 수 있었다. 이러한 결과로 보아 clone된 웅성특이 DNA 단편이 초기배의 성을 조기판정하는데 있어 유용하리라 사료되며, PCR에 의한 초기배의 성 판정에 있어 신뢰할만할 지표가 될 수 있을 것이다.

비록 멀티 페이지 TLB는 성능을 향상시키는데 효과적이지만, 운영체제의 도움을 통한 기존의 방법은 사용자 응용 프로그램에서는 멀티 페이지를 사용할 수 없는 치명적인 단점을 가진다. 이에 본 논문에서는 운영체제의 지원 없이 멀티 페이지를 이용하여 고성능과 저전력을 얻을 수 있는 새로운 멀티 TLB 구조를 제안한다. 제안된 TLB는 작은 페이지를 위한 TLB와 큰 페이지를 위한 TLB로 구성되며, 모두 완전연관 뱅크 구조를 가지고 있다. 작은 페이지를 지원하는 S-TLB(Small TLB)는 큰 페이지를 지원하는 L-TLB(Large TLB)에서 추출된 작은 페이지를 저장하게 되며, L-TLB는 CPU로부터 요청된 작은 페이지를 포함한 큰 가상 페이지 주소를 저장하게 된다. CPU가 요청한 가상주소의 특별한 한 비트와 두 비트를 이용하여 S-TLB와 L_TLB의 각각의 하나의 뱅크만이 접근되며, 동시에 접근되는 엔트리 수 감소에 의해 에너지 소비를 줄일 수 있다. 또한 본 논문에서 효과적인 성능향상을 위해 간단한 1비트 LRU 정책을 제안하였다. 제안된 LRU 정책은 각 TLB 엔트리에 추가적인 1 비트를 사용하여 최근에 참조된 블록을 나타낸다. 이 방법은 간단하게 L-TLB로부터 가장 최근에 참조된 페이지를 선택할 수 있다. 시뮬레이션 결과에 따르면, 제안된 구조는 완전연관 사상 TLB, Dual TLB 그리고 ARM TLB에 비해 76%, 57%, 그리고 6%의 에너지*지연시간을 줄일 수 있었다.

The purpose of this study was to investigate the effect of pelvic traction and muscle energy technique(MET) for hemiplegic patients on static standing balance. The scale for static standing balance is measured by using mean balance(%), frequence(Hz), sway area($mm^2$), sway path(mm), max sway velocity(mm/s), ant/post sway angle($^{\circ}$), lateral sway angle($^{\circ}$), sway number, change of pelvic height is measured in relation to the height of ASIS and PSIS. The subjects of this study were thirty hemiplegic patients: 15men and 15 women, with an average ages of 50.80 years. The thirty subjects were divided into 3 group of 10 at random ; ten subjects had pelvic traction after bobath therapy (the pelvic traction group), ten subjects had muscle energy technique after bobath therapy (the MET group), and ten subjects had only bobath therapy (the control group). Static standing balance was measured using BPM (balance performance monitor; data print software version 5.3), pelvic height was measured using height measuring with an adjustable horizontal arm. In order to assure the statistical significant of the result, an one-way ANOVA, the paired t-test, and a person's correlation were applied at the.05 level of significance. The results of this study were as follows: 1) The change in pelvic height were statistically significant between the pelvic traction group, the MET group and the control group on pre-treatment and post-treatment(p<.05). 2) The change in affected and non-affected on weight bearing were not statistically significant between the pelvic traction group, the MET group and the control group on pre-treatment and post-treatment(p>.05). 3) The change in frequency were statistically significant between the MET group, the control group and the pelvic traction group on pre-treatment and post-treatment(p<.05). 4) The change in sway area were statistically significant between the MET group, the control group and the pelvic traction group on pre-treatment and post-treatment(p<.05). 5) The change in sway pa1h were statistically significant between the pelvic traction group, the MET group and the control group on pre-treatment and post-treatment(p<.05). 6) The change in max sway velocity were statistically significant between the pelvic traction group, the MET group and the control group on pre-treatment and post-treatment(p<.05). 7) The change in ant/post sway angle were statistically significant between the pelvic traction group, the MET group and the control group on pre-treatment and post-treatment(p<.05). 8) The change in lateral sway angle were statistically significant between the pelvic traction group, the MET group and the control group on pre-treatment and post-treatment(p<.05). 9) The change in sway number were statistically significant between the pelvic traction group, the MET group and the control group on pre-treatment and post-treatment(p<.05). In conclusion, there was a difference between the experimental group and the control group. In the future, we have to study continuously about pelvic traction and muscle energy technique in hemiplegic patients.

The purpose of this study is to develop three functions for smartphones and PCs using a textile touch sensor in an everyday sports jacket and to present their usefulness; to this end, we have developed a mutual capacitive textile touch sensor and corresponding structure, and we have implemented three functions into a textile touch sensor jacket, of which we also conducted a usability evaluation. The jacket has a sensor on the wrist of the left sleeve and a device on the left arm. The sensor system can be divided into three main categories: a sensor acting as a switch, a circuit connecting the sensor and the device, and the device that acts as power control and system on/off. The functions are implemented in the texture touch sensor jacket in three modes: cell phone mode, music mode, and PPT presentation mode. We conducted an evaluation of each function in each mode, which indicated that all functions performed well without errors and that the switch had excellent operation for the number and intensity of touch. In terms of usability in a humid environment, the performance of touch functions was found to be equally implemented. In the temperature environment, neither high nor low temperatures caused issues with the functions. A wearing satisfaction assessment evaluated psychological satisfaction, clothing convenience, device convenience, device usability, and device effectiveness. This research jacket is thought to be desirable for the relatively bendable, flexible, and intimate sensor used on the clothing, and the circuit made of conductive fabric tape.

To prevent musculoskeletal disorders(MSD) for dental hygiene students, who will potentially be at high risk of developing MSD while performing oral prophylaxis practice, an MSD prevention education program was designed and was offered to a group of dental hygiene students to find whether the program is effective. Before the program started and three months after the program ended, changes in the students' posture were filmed to observe them. The final subjects for analysis included 30 students in the experimental group and 41 students in the control group. To verify differences between the experimental and the control groups, repeated measures ANOVA was carried out before and after the program. After the education program, the experimental group's RULA scores for neck, left upper arm, right forearm, and wrist, RULA A score on both left and right side, RULA B score on left side, and total RULA score were significantly lowered during the operation on the upper jaw, compared with that of the control group. And, during the operation on the lower jaw, the experimental group's RULA A score, RULA B score, and total RULA score were very significantly lowered. The results of this study suggest the MSD prevention education program is effective in preventing the disorder. Thus, the program can be utilized as an education program for preventing MSDs during dental hygiene students' oral prophylaxis practice and clinical practice.

Purpose: The purpose of this study was to understand the impact of long- and short-term energy drinks on anxiety-like, depressionlike, and cognitive behavior in adolescent rats. Methods: Adolescent rats (age six weeks) were randomly classified into a control group (CON), a long-term administration group (LT), and a short-term administration group (ST). The LT group was orally administered 1.5 mL/100 g (body weight) of energy drink twice daily for 14 days, the ST group was orally administered for one day, and the control group applied the same amount of normal saline. Later, an open-field test, a forced swim test, novel object recognition test, and an 8-arm radial maze test was conducted to assess the rats' anxiety, depression, and cognitive function. Results: There were different effects in the long- and short-term groups of energy drink administration. In the LT group, anxiety- and depressive-like behavior increased because of increased movement in the side corner and decrease of immobility time. Also, the time to explore novel objects decreased, and the number of correct responses was reduced, indicating a learning and memory function disorder. However, the ST group was not different from the control group. Conclusion: These results indicate that long-term consumption of energy drinks can increase anxiety-like, depression-like behavior, and this can lead to decrease in learning and memory functions. Thus, nurse and health care providers should understand the impact of energy drink consumption in adolescence to provide appropriate practices and education.

The purpose of this study is to reveal the effect of electrical stimulation of body composition in obese person. Subjects were 30s to 40s aged healthy workers(2004. 3. 8~4. 17) in the S general Hospital in Suwon and they were brought to manage obesity. Subjects were divided into control group(Female<0.85, Male<0.90) and study group(Female>0.85, Male>0.90) by WHR(waist-hip ratio) that is measured by Automatic body composition analyzer(InBody 3.0). And we divided the study group with randomized methods into group A(n=8) and group B(n=8). Then we compared and analyzed the change of muscle mass, body fat, abdominal girth, WHR, BMI(body mass index) after application of electrical stimulation, three times a week, for 30 minutes in each session with 50 Hz of pulse frequency, $20\;{\mu}s$ or $250\;{\mu}s$ of pulse duration. There was statistically meaningful decrement of body fat(p<0.05) and abdominal girth(p<0.05) but not of body weight, muscle mass, WHR and BMI in the control group after application of electrical stimulation with 50 Hz, $20\;{\mu}s$. There were meaningful change of abdominal girth(p<0.05), WHR(p<0.05) and BMI(p<0.05), but not of body weight, muscle mass and body fat after application of electrical stimulation with 50 Hz, $20\;{\mu}s$ in group A. We applied electrical stimulation with 50 Hz, $250\;{\mu}s$ in group B, then there were meaningful change of body weight(p<0.05), body fat(p<0.01), abdominal girth(p<0.01), WHR(p<0.05) and BMI(p<0.01) but not of muscle mass only. Consequently, the pulse duration is the main parameter of electrical stimulation that affect the body composition of obese person in this study and if we combined the diet control to reduce blood components we could have better result. So it would be more effective to manage localized obesity(in abdomen, thigh, upper arm, etc.) if you apply electrical stimulation considering the pulse duration.
