This study was performed in order to know the histochemical changes of mucosubstances in granular secretions of the serous gland under normal and dry conditions. The frogs were collected near Jinju and the experimental groups were retained under dry conditions for 24, 48, 72 and 96 hours to make a comparison with normal group. The results obtained were as follows: 1. The secreting granules in serous gland of the frog skin contained neutral and weakly acidic mucosubstances. 2. the secreting granules in serous gland of the frog skin were significantly decreased under dry conditions, as is evident from the histochemical properties. The neutral mucosubstances were decreased more than acidic mucosubstances. 3. Histochemical compositions of the mucosubstances of secreting granules in the lumen of the serous gland were not changed according to dry condition.

Objective : A highly effective treatment for interstitial cystitis (IC) remains elusive. We determined whether acupuncture might be effective in relieving symptoms of IC. Method : A consecutive patient(F/67yrs) with symptoms and cystoscopic findings compatible with IC underwent one month of continuous acupuncture by way of needles inserted into acupuncture points which are known to be effective for the symptoms of cystitis. Patient filled out voiding frequency, pain and urgency score charts during treatment. Results : Acupuncture significantly improved all measured parameters toward normal values. Voiding frequency decreased twofold from 41 to 18 voids daily the end of treatment. Pelvic pain on a scale of 1 to 10 decreased from 10 to 2.8. Urinary urgency on a scale of I to 10 decreased from 10 to 5.2. Conclusions : Acupuncture significantly decreased symptoms in a patient with IC. These results suggest that acupuncture may be beneficial in treating IC.

In this paper, we consider a joint optimization of transmitter and receiver in additive cyclostationary noise with zero forcing criterion. We assume that the period of the cyclostationary noise is the same as the inverse of the symbol transmission rate and that the noise has a positive-definite autocorrelation function. The data sequence is modeled as a wide-sense stationary colored random process and the channel is modeled as a linear time-invariant system with a frequency selective impulse response. Under these assumptions and a constraint on the average power of the transmitted signal, we derive the optimum transmitter and receiver waveforms that jointly minimizes the mean square error with no intersymbol interference. The simulation results show that the proposed system has a better BER performance than the systems with receiver only optimization and the systems with no transmitter and receiver optimization.

Aquaporin (AQP) family protein은 일종의 수분 전달 통로 역할을 하는 단백질로 AQP를 통한 수분의 조절은 삼투압을 통한 물의 이동과 함께 조직내 정상적인 수분의 상성 유지에 필수적이다. 현재까지 11종의 AQP이 신장·뇌·정소·안구 등에서 발현이 확인되었다. AQP9은 물 뿐 아니라 carbamide, polyol, purine, pyrimidine, urea, glycerol 등의 이동에 관여한다. 본 연구에서는 생쥐에서 출생 후 성체에 이르는 동안 정소 내 AQP9의 발현, Leydig cell의 분화에 따른 AQP9의 발현을 조사하였다. 1, 2, 4, 8주령의 정소로부터 semiquantitative RT-PCR 및 real time PCR 법으로 AQP9의 발현을 분석한 결과 1주령에서는 발현되지 않았고 2주령에서는 미량이 발현되기 시작하였고, 4주령에서는 성체의 1/2수준으로 발현량이 급격히 증가하였고 성체에서는 다량으로 발현됨이 확인되었다. Semiquantitative RT-PCR 법과 real time PCR법을 비교할 때 주령별 발현 양상은 유사하였으나 4주령과 성체에서는 두 시험법 사이에 양적인 차이가 있었다. 면역조직화학염색 결과 주로 Leydig cell에서 AQP9의 발현이 확인되었다. 성체의 정소 균질액의 Western blot 상에서 분자량 80, 55, 35 및 23 kDa의 항원이 검출되어 dimer, trimer 형태로 존재할 가능성과 당쇄 결합에 의한 단백질의 변형이 있는 것으로 추정된다. 미성숙 개체의 정소에서는 23 form이 확인되는 반면 성체에서는 35 kDa form이 주로 발현되므로 정소에서 발현되는 AQP9의 경우 Post-translation 수준에서 AQP9의 변형이 수반되는 것으로 사료되며 AQP9의 기능과의 연관성은 추후 연구되어야 할 것이다. Leydig cell은 fetal 및 adult type 2종의 세포가 정소발달 과정에 출현, 사멸, 분화하며 이들은 각기 정소발달, 성숙과 정자형성에 필요한 steroidogenesis에 관여한다. 정소 내 AQP9의 발현은 17beta HSD의 발현 양상과 같게 나타나므로 성적 성숙에 따른 정소 내 AQP9의 발현의 증가는 adult type Leydig cell의 분화와 관련된 것으로 추측된다. 성체의 정소로부터 분리한 Leydig cell-enriched culture에 hCG를 처리한 결과 배양체의 AQP9의 발현이 증가하므로 AQP9은 LH 수용체 하위 신호전달과정을 통해 Leydig cell의 steroidogenesis 또는 생성된 steroids의 분비에 요구되는 수분 및 중성용질의 이동에 관여하는 것으로 사료된다.

This study aims at analyzing the convergence of Internet-of-Things and wearables technologies using cooperative patent classification(CPC). CPC, introduced to an increasing number of technological fields of Korean patents, is expected to be widely used in Patent Informatics because the classification codes in CPC are more specific than those of IPC, which reflect the characteristics of technologies in detail with accuracy. CPC has seldom been used up to date and most of the previous researches on technological convergence used IPC. As a pre-analysis step for analyzing the trend of technological convergence of IoT and wearables, CPC and IPC codes assigned to each patent were compared. By applying association rule mining to the analysis of CPC codes, we identified the technological fields where convergence frequently takes place and examined the trend of technological convergence over time.

The primary and secondary survey was designed to identify all of a patient's injuries and prioritize their management. However 15 to 22.3% of patient with missed injuries had clinically significant missed injuries. To reduce missed injury, special attention should be focused on patients with severe anatomical injury or obtunded. Victims of blunt trauma commonly had multiple system involvement. Some reports indicate that inexperience, breakdown of estalished protocol, clinical error, and restriction of imaging studies may be responsible for presence of missed injury. The best way of reducing clinical significant of missed injuries was repeated clinical assessment. Here we report a case of severe blunt hepatic injury patient and pericardial injury that was missed in primary and secondary survey. After damage control surgery of hepatic injury, she remained hemodynamically unstable. Further investigation found cardiac tamponade during intensive care. This was managed by pericardial window operation through previous abdominal incision and abdominal wound closure was performed.

Grid computing, a mechanism which uses heterogeneous systems that are geographically distributed, draws attention as a new paradigm for the next generation operation of parallel and distributed computing. The importance of grid computing concerning communication cost is very huge because grid computing furnishes uses with integrated virtual computing service, in which a number of computer systems are connected by a high-speed network. Therefore, to reduce the execution time, the scheduling algorithm in grid environment should take communication cost into consideration as well as computing ability of resources. However, most scheduling algorithms have not only ignored the communication cost by assuming that all tasks were dealt in one cluster, but also did not consider the overhead of communication cost when the tasks were processed in a number of clusters. In this paper, the functions of original scheduling algorithms are analyzed. More importantly, the functions of algorithms are compared and analyzed with consideration of communication cost within the co allocation environment, in which a task is performed separately in many clusters.

CGI not only performed a crucial role to make cinema and animation evolved into digital cinema and digital animation but also CGI, an important visual format, settled realism-centric spectacle image culture in public commercial cinema and animation. The fact that CGI visual format could be structuralized in three different view points is discovered through Iconicity, photorealism, verisimilitude, uncanny valley, hyperrealism, and spectacular realism discourse research which explain image culture. First, a formative viewpoint that comes up in an iconic difference between drawing and photograph. Secondly, a cognitive viewpoint that sees visually perceived naturalness and abnormality as a realistic probability issue. Lastly, a customary viewpoint which is rooted in aesthetic tradition of cinema and animation. After that, the features of CGI which is used in the movie 'jungle book'(2016) were analyzed using the structured visual format. Consequently, this movie has hyper-realistic photographic iconicity on the base of realistic probability. Also, by following image-aesthetic convention which uses overstated and amplified narrative as a visual format, at the same time, the movie also has sufficient image-aesthetic convention in animation by personified animal character.

The quality of life is emphasized as one of the important issue in modern society. Such attention to quality of life started getting more attention lately as it is coupled with the country's competitiveness. In spite the quality of life is very significant, the level of the quality of life in the country is not satisfactory. So, the purpose of this study was to analyze the Korean standard measuring technology in terms of the QOL. First, We identified constructs of the QOL on the basis of several studies to derive an analytical framework. Then, We analyzed the distribution of the measurement standard technology in the country in accordance with the framework. The results of the analysis, many of the current measurement technologies described it regardless of the quality of life. Even if the technologies are relevant. they showed a state biased to the economic QOL. This means that QOL was not considered in the measurement technology standard. Therefore the further improved will be needed.
