Background: The purpose of this study was to investigate the effect of structured cryotherapy on edema of patients who had a total knee arthroplasty (TKA). Methods: The subjects were 58 patients who were diagnosed with osteoarthritis and had total knee arthroplasty in D hospital. In total, 29 people were in the leg elevation cryotherapy group (LECTG), 29 people were in the control group (CTG). After TKA, the patients' swelling on post operation days (POD) 3 were checked. After the post OP checking, LECTG was treated with cryotherapy with leg elevation for 12 days but CTG was cryo therapy with sit on chair. Results: Swelling show significant difference within the group (p<.05), but did not show signigicant difference between groups (p>.05). Conclusions: Base on the results, it was found the cryo therapy of $-78^{\circ}C$ improved swelling after TKA. Accordingly, it is thought that cryo therapy of $-78^{\circ}C$ has positive effect on swelling in the process of recovery after operation. but It did not approve that the leg elevation was even more effective. For this study, the reserch developed to enhance the effectiveness of the cryotherapy, would make it possible to apply to an effective cryotherapy posture.

Purpose : The purpose of this case report was to examine the effects of intergrative intervention approach on a patient with lumbar herniated nucleus pulposus (HNP). Methods : The subject was a 53 years old woman with lumbar HNP. The subject received conventional physical therapy combined with exercise therapy and manual therapy. Pain on visual analog scale (VAS), finger to floor (FTF), lumbar lateral flexion, L5 motor, and straight Leg-Raising (SLR) were evaluated at baseline and after 4 weeks. Results : The change of VAS, FTF, left lateral flexion, and right lateral flexion were decreased (9 vs. 5, 41 vs, 25, 56 vs. 42, 54 vs. 41, respectively) and the change of L5 motor and SLR were increased (Fair vs. Fair+, 60 vs. 75, respectively). Conclusion : Our findings suggest that Integrative intervention may be considered in patient with lumbar HNP.

This study was conducted in order to observe the changes in cellular associations of seminiferous tubules from 8 to 20 weeks of age and to obtain the cycle and relative duration of the seminiferous epithelia from 24 to 32 weeks of age. Twenty-eight Korean native male goats were used in the experiment and divided into 7 groups, consisting of 4 goats each, with four weeks intervals from 8 to 32 weeks of age. The results were summarized as follows; 1. Gonocytes were seen at 8 weeks of age, however they were not observed as from 12 weeks. Both type A-spermatogonia and type B-spermatogonia occurred from 8 weeks, while primary spermatocytes were found from 12 weeks. Secondary spermatocytes and spermatids appeared from 16 weeks, and increased in numbers sequentially until 32 weeks of age. Spermatozoa were observed at first at 20 weeks of age. 2. Type A-spermatogonia appeared approximately twice as many at stage 2 as compared to stage 1, while the same numbers of cells were seen in both stages 1 and 8, showing the least number among 8 stages of the cycle of the seminiferous epithelia. The type B-spermatogonia were found during the stage 5 to 8, not to be detactable during stage 1 to 4. The number of primary spermatocytes of the leptotene phase increased markedly during stage 1 to 4, and decreased afterwards. The primary spermatocytes of the pachytene phase were shown the least in number at stage 4. The secondary spermatocytes could be seen only at stage 4 and the largest number of spermatids was seen at the stage 4 among 8 stages. 3. The relative frequencies of each stage among stages 1 to 8 of the cycle of the seminiferous epithelia were 27.5, 17.5, 12.8, 5.8, 8.9, 8.3, 12.0 and 7.2% respectively. 4. Some of the nuclei of Sertoli cells transformed from the "parallel" type to the "perpendicular" type. This evolution took place from stage 1 to 6, when the number of "perpendicular" type nuclei reached a peak and the number was decreased in the rest of the stages. Thus, establishment of spermatogenesis in Korean native goats was completed at the age of 20 weeks.

The purpose of this pilot case series was to evaluate the clinical and radiographic outcomes of employing newly developed alloplastic biphasic calcium phosphate (BCP) in guided bone regeneration (GBR) for maxillary anterior peri-implant defects. Six peri-implant dehiscence defects were grafted with BCP. For all included treatment sites, clinical (defect width [DW] and defect height [DH]), radiographic (horizontal hard tissue thickness [HT]), patient discomfort, and early wound healing outcomes were evaluated. At reentry surgery, all surgical sites indicated a change in DW, DH, HT0, HT1, HT2, and HT3 from 4.08±1.39 mm to 1.13±1.76 mm, 3.57±1.42 mm to 0.58±1.09 mm, 2.18±0.66 mm to 1.50±0.53 mm, 2.11±0.57 mm to 1.73±0.28 mm, 2.22±0.54 mm to 1.75±0.26 mm, and 2.63±0.87 mm to 1.83±0.46 mm, respectively. Significant differences were discovered between paired DW and DH (p<0.05), whereas radiographic parameters had no significant differences. The severity of pain and swelling was 4.8±1.9 and 6.5±1.9, respectively, and the duration of pain and swelling was 4.5±3.8 and 5.8±2.9 days, respectively, according to early postoperative discomfort assessment. No adverse reactions occurred at any treatment site. In terms of clinical and radiographic outcomes, the newly developed BCP is acceptable biocompatible and suitable for the GBR of maxillary anterior peri-implant dehiscence defects within the limitations of this study.

최근 국내 도로 사업은 예산투자 및 시설규모가 적정수준에 도달하였거나 또는 중복 과잉 투자되고 있다는 논란이 증가함에 따라 도로의 추가적인 건설에 대한 부정적 인식이 확산되고 있는 실정이다. 실제로 최근 도로부문에 대한 2003년 약 9조 원이 투자된 이후로 지속적으로 감소하여 2007년 약 7조 3천억 원 수준으로 감소하고 있다. 도로시설이란 각 산업부문과 국민경제에 큰 영향을 끼치는 중요한 생산요소이며, 이에 대한 투자는 경제 성장에 있어 필수불가결한 요소이다. 따라서 효율적인 투자를 위해 적정 도로시설 규모를 산정하는 것은 매우 중요하다. 본 논문에서는 도로보급률 관련 기존 지표와 추가 지표를 제안한 후 OECD국가들 중 적합한 비교 대상(국토계수가 유사)을 선정하여 우리나라의 도로스톡 수준을 비교분석하였다. 또한 소득수준이 GDP 2만 달러(2007년 기준)에 도달함에 따라 향후 3만 달러, 4만 달러 도달 시 목표 스톡량을 확보하기 위한 우리나라 도로시설의 규모를 선정하였다. 정교한 이론이 부재한 상황에서, 국토면적, 자동차보급대수, 인구, 소득수준 등을 활용하여 국가간 도로보급률을 비교분석하는 것은 우리나라의 현 수준을 진단하고 미래 목표를 설정하는데 있어서 실용가치가 매우 높다고 하겠다. The Investment to road projects has been a hot issue in the aspect of its possible overlapping or overinvestment in Korea. Therefore, additional road construction is not always accepted in these days. This paper investigated several indices including the country index and the road-extension rate index as well as a newly developed index for identifying and comparing road stocks among the OECD countries. Furthermore, the study has estimated some reasonable amount of additional road stocks of Korea when its GDP becomes twenty thousands per capita to forty thousands per capita in future by comparing the amount of stacks of OECD countries at those times. The result can be used for setting the target of road stocks in practical manner in the absence of the universally accepted theory in the road stock provision arena.

Bi 과잉에 따른 BiFeO<sub>3</sub>-BaTiO<sub>3</sub> 세라믹스의 압전 및 유전특성
이재홍,이명환,송태권,김원정,성연수,김명호,Lee, Jae Hong,Lee, Myang Hwan,Song, Tae Kwon,Kim, Won-Jeong,Sung, Yeon Soo,Kim, Myong-Ho 한국재료학회 2017 한국재료학회지 Vol.27 No.3
The effects of an excess of Bi on the piezoelectric and dielectric properties of $0.60Bi_{1+x}FeO_3-0.40BaTiO_3$ (x = 0, 0.01, 0.03, 0.05, 0.07) were investigated. The ceramics were processed through a conventional solid state reaction method and then quenched after sintering at different temperatures in the range of $980{\sim}1070^{\circ}C$. A single perovskite structure without any secondary phase was confirmed for all compositions and temperatures. It was found that excess Bi reduced the sintering temperatures, acted as a sintering aid and enhanced the properties in combination with quenching. Curie temperature ($T_C$) was found to slightly increase due to the presence of excess Bi; electrical properties were also improved by quenching. At x = 0.03 and $1030^{\circ}C$, remnant polarization ($2P_r$) was as high as $45.4{\mu}C/cm^2$ and strain at 40 kV/cm was up to 0.176 %.
