This study was performed to investigate the impact of the Neurocognitive Rehabilitation Therapy on the upper limb function recovery of patients with stroke and their abilities to perform daily activities and to provide basic data for a long-term treatment. A total of 30 patients with hemiplegia that occurred due to stroke were recruited as subjects of the present study, and 15 patients were randomly assigned to a Neurocognitive Rehabilitation Therapy group and a conventional treatment group, respectively. And, tests were performed over four weeks, five times a week, and 30 minutes a session. Manual Function Test(MFT), Fugl-Meyer Assessment Scale(FMA), and Korean-Modified Bathel Index(K-MBI) were used to measure the degree of the functional recovery before and after the experiment. According to the data of this study, in the upper limb function test, the Neurocognitive Rehabilitation Therapy group showed significant increase of the measurement values of MFT and FMA(p <.05), and when the difference between the two groups were compared, the upper limb function showed a statistically significant difference. In the daily activity performance test, only the Neurocognitive Rehabilitation Therapy group showed a significant improvement of K-MBI value(p <.05). Based on the results of the present study, it was demonstrated that the Neurocognitive Rehabilitation Therapy was effective in enhancing the upper limb functions and daily activity performance of patients with stroke.

This study was conducted to investigate the effects of γ-aminobutyric acid (GABA) and a probiotic mixture on egg quality, blood parameters, and corticosterone content in broiler breeder stock in summer in Korea. A total of 72 broiler breeders (Arbor Acres) at 49 weeks old were randomly divided into the following three groups of 24 heads each: control, GABA, and probiotics (1 × 10⁸/g Bacillus licheniformis, 1 × 10⁷/g Lactiplantibacillus plantaru, and 1 × 10⁷/g Clostridium butyricum). The hens were fed a diet containing 50 mg of GABA/kg of feed and 0.1% probiotics for 6 weeks. Egg quality, blood parameters, and stress levels (corticosterone concentration) of the broiler breeders were evaluated. No significant differences were observed in the egg weight, albumen height, Haugh units, yolk color, shell thickness, or shell strength between the groups. There were no significant between-group differences in the blood biochemical profile, including total cholesterol, triglyceride, glucose, total protein, aspartate aminotransferase, alanine aminotransferase, albumin, and inorganic phosphorus concentrations. The corticosterone concentration was significantly lower in the GABA and probiotics groups than the control group (P < 0.05) at 6 weeks of age. In conclusion, these results suggest that dietary probiotics and GABA significantly improve the stress levels of broiler breeders in summer in Korea.

This study is an experimental study comparing the psycho-physiological response differences of subjects according to the rapport building in polygraph tests. We randomly assigned 84 adults into a 2(veracity: Truth vs. Lie) x 2(rapport; Rapport building vs. Non-rapport building) between-subject design and measured ESS total scores as psycho-physiological responses. In order to manipulate the veracity conditions, participants in the truthful condition were told to tell their actual scores on several simple tasks but those in the lie condition were asked to tell higher scores than their actual scores. Afterwards all participants were polygraph tested in the order of pre-interview and main examination. The rapport conditions were manipulated by structured pre-interview scripts. As a result, there were significant differences in the examinee's total ESS scores depending on the veracity and rapport conditions. For truth-tellers, the ESS total scores were greater in the positive(+) direction in the rapport building condition than in the non-rapport building condition, indicating a prominent true response in the former condition. For liars, however, the ESS total scores were not significantly greater in the negative(-) direction in the rapport building condition than in the non-rapport building condition. Based on this study's results, we discussed the importance of rapport building in the pre-interview phase of a polygraph test and the need to operationalize verbal and non-verbal rapport building techniques.

Objective : The purpose of this study was to identify the effect of crafts and handwriting on bilateral coordination during task performance. Methods : Randomly selected 30 college students without hand disability were invited for the study, and grouped 3(test group 1 for crafts, test group 2 for handwriting, and control group) with 10 students per group respectively. Then Jebsen-taylor hand function test, Purdue pegboard test, and Minnesota manual dexterity test were employed for evaluating changes before and after the intervention. Results : After training intervention of crafts and handwriting for two test groups, test groups showed better bilateral coordination significantly than the control group. Especially test group 1(crafts) showed a bigger difference at Jebsen-taylor hand function test, and likely test group 2(handwriting) did at Purdue pegboard test. Conclusion : It was found that crafts increase bilateral coordination, while handwriting increase hand dexterity during task performance. That is, crafts and handwriting affect tasks differently. Further studies applying various crafts and handwriting for many age groups will be helpful for identifying the better way of occupational intervention for individuals in lack of bilateral coordination.

This study has investigated the bioavailability of calcium in eggshell powder (ESP) fortified ramen. Wean-ling SD rats were maintained for 2 weeks on 0.05$\%$ low calcium diet then assigned randomly to one of 5 groups. Animals were provided for 4 weeks one of 3 different experimental diets containing 0.15$\%$ calcium as $CaCo_{3}$, NFDM, or ESP fortified ramen. Two control groups were fed either 0.05$\%$ calcium or general ramen containing 0.08$\%$ calcium. The body weight, diet intake, food efficiency ratio (FER), bone growth, calcium contents of bones, and apparent absorption were measured. Experimental results show that regardless of calcium sources 0.15$\%$ calcium groups increased body weight, weight and length, calcium content, and the strength of two bones (tibia and femur) significantly compared to 0.05$\%$ calcium group. The apparent absorption rate of calcium also showed similar results supporting the bioavailability of ESP fortified ramen is not inferior to either NFDM or $CaCO_{3}cdot$ The results indicate that ESP fortified ramen is a proper mediate for calcium fortification in Korea.

비휘발성 메모리 Fe-RAM은 빠른 정보처리 속도와 전원공급이 차단되었을 때도 계속 정보를 유지할 수 있는 비휘발성 특징과 더불어 저전압, 저전력 구동의 장점이 있어서, 차세대 메모리로 많은 주목을 받고 있다. FeRAM에 사용되는 강유전체는 주로 Pb(Zr,Ti)$O_3$가 적용되었는데, 최근에는 비납계 강유전체의 연구도 활발히 이루어지고 있다. 이러한 비납계 강유전체 중에서 가장 특성이 우수한 물질은 $(Bi,La)_4Ti_3O_{12}$ (BLT) 이다. 그런데 BLT는 결정 방향에 따른 강한 이방성의 강유전 특성을 나타내기 때문에 BLT 박막을 이용하여 Fe-RAM 소자 등을 제작하기 위해서는 결정의 방향성을 세심하게 제어하는 것이 매우 중요하다. 지금까지 연구된 BLT 박막의 방향성 조절결과를 보면, BLT 박막을 스핀 코팅 법 (spin coating method)으로 증착하고, 핵생성 열처리 단계를 조절하여 무작위 방향성을 갖는 박막을 제조하는 방법이 일반적이었다. 그런데 이러한 스핀 코팅법에서의 핵생성 단계의 제어는 공정 조건 확보가 너무 어려운 단점이 있다. 이러한 어려움을 극복할 수 있는 대안은 스퍼터링 증착법(sputtering deposition method), PLD (pulsed laser deposition)법 등과 같은 PVD (physical vapor deposition) 법의 증착방법을 적용하는 것이다. PVD 법으로 증착하는 경우에는 이미 박막 내에 무수한 결정핵이 존재하기 때문에 핵생성 단계가 필요가 없게 된다. PVD 증착법의 적용을 위해서는 타겟의 제조 및 평가 실험이 선행되어야 한다. 그런데 벌크 BLT 재료의 소결공정 조건과 전기적 특성에 관한 연구 결과는 거의 발표가 되지 않고 있다. 본 실험에서는 $Bi_2O_3,\;TiO_2,\;La_2O_3,\;Nb_2O_5\;and\;Al_2O_3$ 분말들을 이용하여 최적의 조성을 구하기 위하여 $Nb^{+5}$ 와 $Al^{+3}$을 $Ti^{+4}$ 자리에 소량 치환시켜 제조하였다. 혼합된 분말을 하소 후 pellet 형태로 성형하여 소결을 실시하였다. 시편을 1mm 두께로 연마하고, 양면에 silver 전극을 인쇄하여 전기적 특성을 측정하였다. 측정결과 $Ti^{+4}$ 자리에 $Nb^{+5}$를 치환하여 제조한 시편에서 $2P_r{\sim}31\;{\mu}c/cm^2$정도의 매우 우수한 특성을 얻었다.

The purpose of this study was to investigate the effect of resistance exercise with vibration stimulation methods on static balance and gait parameters in experienced back pain adults. This study was Three group pretest-posttest design. A total of 30 experienced back pain adults voluntarily participated in the study. Subjects were randomly assigned to the resistance exercise with 8 Hz vibration stimulation(n=10), resistance exercise with 30 Hz vibration stimulation(n=10), and lumbar stabilization exercise groups(n=10). The static balance and the gait parameters, as such stance phase, swing phase, stride length and cadence, were measured using balance measuring equipment and gait analysis treadmill at before and after 6 week. Intervention of each group were performed, three times a week for 6 weeks, and 30 minutes a day. The effect of intervention on static balance, stance phase, swing phase, stride length and cadence were significantly differences after 6 weeks in each group(p<.05). In the comparison of the effects between the groups, static balance and stance phase were significantly difference after 6 weeks(p<.05), but in the swing phase, stride length and cadence, there were no significant differences. As a result, it is considered that resistance exercise with vibration stimulation improved leg muscle strength by a mechanism causing muscle contraction, and the strengthened leg muscle enhanced had a positive effect on balance ability. And improved balance ability was considered a more positive effect on walking ability by allowing the body to stably control posture while moving.
