Microtubule-associated protein 1B (MAP1B), a member of MAP1 family, plays a key role in neuronal development. MAP1B binds to many kinds of proteins directly or indirectly. This study was performed to investigate whether MAP1B interacts with GAPDH in bovine follicles using immunoprecipitation (IP) with Western blot analysis and immunohistochemisty. The mRNA expressions of MAP1B and glyceraldehydes 3-phosphate dehydrogenase (GAPDH) were down-regulated in bovine follicular cystic follicles (FCF). In parallel with the mRNA levels, their protein levels were also down-regulated in FCFs. In addition, MAP1B and GAPDH were co-localized at the cytoplasm of follicles. IP with Western blot analysis showed that MAP1B bound to GAPDH in normal follicles, but their binding was absent in FCFs, suggesting a low level of MAP1B and/or GAPDH expressions in FCFs. Taken together, these results suggest that MAP1B interacted with GAPDH may play a role in bovine follicle development, and that GAPDH does not function always as a loading control in bovine follicles.

This investigated the romanticism of Alessandro Michele who leads new trends in fashion industry as a creative director for Gucci. In this study, 307 women's wears exhibited by Alessandro Michele for 3 years in Milan collections from 2015 F/W to 2017 F/W are categorized according to the aesthetic characteristics of romanticism. Additionally, the five aesthetic features of Gucci's fashion design are an addition since the appearance of abnormally large size under the influence of postmodernism. The results based on the study purpose are as follows. First, the decoration makes the garments stand out by using fancy materials, splendid multicolor combination, applique embroidery and three-dimensional objects. Second, exotic style is expressed from an occidental perspective using Chinese traditional fashion or textiles, and exotic accessories. Thirdly, sensuality is manifested using see-through materials to emphasize women's breasts, or the beautiful and sexual expression of women's body. Fourth, the new creations are designed by combining contrasting elements, such as disparate materials and, different genders. Furthermore, traditional cultures like baroque and rococo, and the 1970's vintage looks inspires the creation of retro-style. Finally, the appearance of extremely large shoulders, silhouettes, and details of the human body can be explained with expansive tendency. The aforementioned results further suggest that diverse characteristics are expressed via reflection of contemporary art and trends.

This essay attempts to suggest a third way to interpret probabilities based on diagnoses of weaknesses and strengths of the objective and the subjective interpretations. While the objective interpretations capture important intuitions in employing probability, it can provide the definitions of probability only in a circular way. Although the subjective interpretations seem to avoid this problem, it also fails to understand how one can extract certain information from the ignorance of a given system. It will be suggested that these problems can be bypassed if we consider probabilities as theoretical structure, which provide significant generalizations about the world.

The geochemical exploration was carried out of the soil systems in the survey areas(Mt. Subang area). The chemical values of soil samples for soil in this area are defined such as over values of Ag : 11 ppm(Average ： 1.91 ppm), Au 548 ppb(Average 42.39 ppb), Cu : 89 ppm(Average：51.40 ppm), Pb：190 ppm(Average ： 23.69 ppm), Zn : 157 ppm(Average : 61.78 ppm), respectively. Anomalous areas for each element have been chosen based on the factors such as, geologic settings, geochemical survey, chemical analysis of ore, chemical analysis of soil. statistical processing of the chemical analysis. Therefore, multi-elements anomalies area were recognized in the east-center part of the study area.

수면단계는 수면감성을 평가하는데 있어서 중요한 생리지표로서 사용되어왔다. 그러나 수면다원검사를 이용한 전통적 수면단계 분류방법은 뇌전도, 안전도, 심전도, 근전도 등을 종합적으로 측정하므로 수면단계를 비교적 정확히 분류할 수 있지만 피험자에게 심한 구속감을 주는 문제가 있다. 본 연구에서는, 각성상태에서 교감신경계가 지배적인 반면에 수면 중에는 부교감신경계가 더 활동적인 점에 착안하여 수면단계를 간단히 분류할 수 있는 방법을 찾고자 수면단계에 따른 심박동변이도(heart rate variability: HRV)를 분석하였다. 단일채널 심전도를 이용하여 수면단계별로 HRV 의 교감신경계/부교감신경계 활성도의 비율을 분석한 결과, W(wakefulness) 단계가 NREN(non REM) 2 단계, 3 단계, 4 단계에 비하여 높게 나타났으며, NREM 4 단계는 REM(rapid eye movement) 단계와 NREM 1단계에 비하여 낮게 나타났다. 또한 교감신경계/부교감신경계 활성도 비율의 수면단계에 따라 변화하는 양상은 W, REM, NREM 1, 2, 3, 4 단계의 순으로 단조 감소하였다.

Uvulopalatopharyngoplasty(UPPP) is an operation that is frequently performed for the patient of obstructive sleep apnea(OSA). A major problem has been to select those patients who will have a good response to UPPP. We compared preoperative and postoperative polysomnography(PSG) in 20 patients to evaluate the success rate of the operation. Each subject underwent a cephalometric roentgenogram, and fiberoptic nasopharyngoscopy with Mueller maneuver was applied in roentgenogram and fiberoptic nasopharyngoscopy with Mueller maneuver was applied in preop evaluation of patients with OSA. No PSG parameter could accurately predict the changes in sleep after UPPP. There were no significant differences between the responders and the nonresponders concerning the cephalometric analysis, the type of obstruction by Mueller maneuver, and body mass index(BMI). The conclusions of this study are thus that UPPP is an effective treatment for the OSAS with a high success rate, but that there is no single useful parameter predicting the success of the operation.

In this paper, we propose a new construction method of binary low correlation zone (LCZ) sequence set. New construction method applies Gray mapping to conventional quaternary LCZ sequence set that has specific property. The period of new binary sequence set is twice as that of used sequence set in construction, and maximum magnitude of correlation value within the LCZ and cardinality of new set is also twice as those of used quaternary sequence set. But the LCZ size is the same with that of used sequence set. If the used Quaternary sequence set is optimal, the constructed binary sequence set is optimal with high probability.

In this paper, we propose a sleep efficiency measurement algorithm based on IR-UWB radar sensor in distance. Among the vital signs which can be measured by the IR-UWB radar sensor such as breathing rate, heartbeat rate, and movement, we analyzed correlation between the movement and the sleep efficiency, and based on the result, we propose a sleep efficiency measurement algorithm. In order to verify the performance of the proposed algorithm, we applied the algorithm to three polysomnography patients in hospitals and obtained the performance of an average absolute error within 3.9%.

The standardization of third Generation Partnership Project(3GPP) has been performed in of order to support interactive multimedia services under mobile environments. In this 3GPP, transmit diversity solutions are applied to increase the available diversity effectively using 2 or more antennas. In this paper, we analyzer the performances on STTD(Space Time Transmit Diversity) technique and its modified techniques such as STTD-OTD, CL-STTD, and 4TX-STTD out of open loop transmit diversities that the standardization of 3GPP has released. We also propose the open loop transmitter and receiver diversities to add the receiver diversity. We analyze and discuss the performance of the proposed techniques and using the Matlab simulation under the flat fading channel environment.

ZrNbFeCu-xSn 합금을 진공 아크 용해법으로 제조하여 $360^{\circ}C$의 물, $400^{\circ}C$의 수증기 및 36$0^{\circ}C$의 70ppm LiOH 분위기에서 부식실험을 실시하였으며, 시편의 미세구조는 광학현미경, SEM 및 TEM으로 관찰하였다. 36$0^{\circ}C$에서 210일까지 부식 실험한 결과 대부분의 합금이 천이 전 영역에서의 부식거동을 보였다. $400^{\circ}C$ 경우, 초기에는$ 360^{\circ}C$에서의 부식거동과 비슷한 경향을 보였으나 80일 이후부터는 천이현상이 발생하여 부식속도가 급격히 증가하는 경향을 나타내었는데, Sn량이 많을수록 보다 빠른 시간에 천이현상이 발생했다. LiOH 용액에서는 전반적으로 $400^{\circ}C$에서 보다 더 늦은 시간에 천이현상이 발생했다. 석출물은 Zr(Fe,Cu)$_2$나Zr(Fe,Cu)$_3$로 추정되는 성분을 가지지만, Sn의 증가에 따라 석출물의 조성이나 크기는 거의 변화가 없는 것으로 관찰되었다.
