  • SIAS unit로 개질된 PET의 열적 성질을 조사한 결과, SIAS unit의 함량이 증가함에 따라 $T_g$는 증가, $T_m$은 감소하는 경향을 보였으며 결정화속도는 크게 감소함을 관찰할 수 있었다. 결정화속도의 감소는 극성과 크기가 큰 술폰산 나트륨기가 쇄의 유연성을 크게 감소시켜 결정표면으로 확산 이동한 고분자 쇄가 결정형태로 재배치 하는 것을 방해하는 것이 중요한 원인으로 생각되며, 결정성장기구는 SIAS unit의 함량에 의해 크게 좌우되어 SIAS unit의 함량이 증가할 수록 3차원 공간으로의 결정 성장이 제한 받음을 관찰 할 수 있다.

  • The objective of the present study lies in constructing web-based GIS system providing broad range of information applicable for power/telecommunications distribution facilities through cable. Nowadays, Korea is renowned forits faste sttele communications network across the nation enjoyable for being a test-runbed by worldwide contents providers. It is not too much to say that the trend is caused by the fact that Korea utilizes the cobweb-like power transmission cables applicable for the nationwide telecommunications networking. In particular, the trend has been all the more encouraged by the governmental drive to expedite the telecommunication network by way of the established power transmission facilities deemed as publicutility. Nevertheless, few can deny that the overexcessive competition among telecommunication service providers increasingly gives rise to unauthorized, arbitrary facilitation of distribution devices, which becomes much burden in operating the normal power/telecommunications distribution facilities by a power-generating company. In this regard, the study, to cope with such problems, attempts to develop a web GIS-based information management system compatible with NDIS(New Distribution Information System), a distribution facility management system now under operation by KEPCO, making advantage of GE Energy's SIAS(Smallworld Internet Application) technology. The model provided by this study is expected to get closer into effective operation of distribution facilities along with better sharing of information among conventional telecommunications operators, while getting rid of infringed facilitation cases

  • Insulin resistance is a risk factor for stroke or recurrent stroke. Sedentary behavior increases insulin resistance. This study aimed to identify the relationship between physical impairments and functions and insulin resistance, examining which physical impairments specifically influence insulin resistance the most. The subjects of this study were 63 stroke patients. The subject's insulin resistance and physical impairments and functions were measured using the Chedoke-McMaster Stroke Assessment (CMSA) and Stroke Impairment Assessment Set (SIAS). The study results exhibited that insulin resistance is statistically significantly related to the variable of foot according to the CMSA(r=.95, p<.05) and to the variable of lower extremity sensory function (touch) in relation to the SIAS(r=.91, p<.05). This study also revealed close correlations between insulin resistance and the variables of ankle control(${\beta}=-1.05$, p<.05) and low extremity tactile sensations(${\beta}=-1.82$, p<.05).

  • Background: Breast cancer is one of the most common cancer types in women and is amongst the most devastating and stressful events in the life of women. The external appearance of breast cancer patients usually changes due to the surgical and/or medical therapies used. An association may be found between social support perception and social appearance anxiety in patients with breast cancer in the period after mastectomy. Therefore, this study investigated the social appearance anxiety and social support status in women with breast cancer in our country. Materials and Methods: A descriptive cross-sectional study was conducted in breast cancer patients undergoing treatment or follow-up in Medical Oncology and General Surgery departments. Results: The mean age of the participants was $51.13{\pm}8.48$ years (range, 24-74 years) with nearly half of the patients (40.6%) aged 40-50 years. Of the patients, 39.1% had stage 3 breast cancer. The mean score on Cancer Patient's Social Support Scale (CPSSS) was $134.85{\pm}9.35$, and there was a significant difference in CPSSS total scores betweena the age groups, educational levels, self-reported income levels and stage of disease (p<0.05). The mean Social Image Anxiety Scale (SIAS) score was found to be $34.30{\pm}9.35$ (min:16, max:66) in women participating in this study. The CPSSS and SIAS scores of the participants were inversely correlated, and the SIAS score was found to decrease with the increasing CPSSS score but with no statistically significant difference (r=-0.110, p=0.217). Conclusions: Social appearance anxiety is higher in the patients with poor social support.

  • Objective : Social anxiety disorder (SAD) is characterized by fear of social threat and exhibits limbic hyper-reactivity toward social stimuli such as emotional faces. A previous study identified the uncinate fasciculus (UF) sub-tract as particularly related to facial memory. To explore the white matter tract relating to face-specific brain regions, we investigated the UF sub-tract in SAD. Methods : The diffusion tensor images of 22 patients with SAD and 20 healthy controls were analyzed with tractography. The UF sub-tract was delineated using the regions of interest of face patches in the anterior temporal lobe and the orbitofrontal cortex, and fractional anisotrophy (FA) and total number of streamlines (ST) were analyzed. We examined the group comparison of FA and ST of the UF sub-tract and correlations of FA and ST with the social anxiety symptoms such as the Liebowitz Social Anxiety Scale (LSAS), the Social Interaction Anxiety Scale (SIAS), the Social Phobia Scale (SPS) and the Fear of Negative Evaluation scale (FNE) in SAD. Results : There were no group differences in FA and ST of the UF sub-tract. However, negative correlations were observed between ST of the right UF sub-tract and severity of social anxiety symptoms (LSAS, rs=-0.480, p=0.024; SIAS, rs=-0.580, p=0.005; SPS, rs=-0.590, p=0.004; FNE, rs=-0.675, p=0.001) in patients with SAD. Conclusion : Although patients with SAD did not show quantitative abnormalities in the UF sub-tact connecting face-specific brain regions, this structure seems to play a role in the symptom severity of SAD.

  • The aim of this experiments were to assess the time-interval change of motional characteristics in frozen-thawed semen of Korean native cattle (KNC) by using computer aided semen analysis (CASA) technology. Twenty-six KNC frozen semen straws were obtained from Korean KNC improvement department, livestock improvement main division, national livestock cooperatives federation in Korea. Specimens were allowed to thaw at $37^{\circ}C$ for 30 sec in water bath. Semen analysis was performed on semen image analysis system (SIAS, Medical supply, Korea) adjusted to the gate settings and used the semen droplet ($5{\mu}l$) placed on Makler counting chamber (Sefi medical instrument, Israel) prewarmed at $37^{\circ}C$. The same person used the same micropipette to fill the Makler counting chamber. A total of 150 or more of sperms were analysed in each specimen by a single trained person by scanning at least 5 to 10 fields. The measurement parameters in SIAS were as follows ; frame rate = 30 frames per sec, image capture = 1 sec, minimum motile speed = $10{\mu}m/s$, maximum countable sperm number = 400. Statistical analysis was done by Student t-test with use of the Sigma plot program on a IBM personal computer. The dancemean(DNM) and hyperactivated sperm(HYP) of frozen-thawed KNC semen kinematics were significantly decreased(p < 0.05) after 10 min of incubation at $37^{\circ}C$ water bath. But, wobble(WOB) of same sample semen was significantly increased(p < 0.05) after 10 min of incubation and significantly decrease(p < 0.05) after 60 min of same incubation. And, after 30 mim of incubation, significantly differences were found most of motion kinematics, motifity(MOT), curvilinear velocity(VCL), straight line velocity(VSL), average path velocity(VAP), amplitude of lateral head displacement(ALH), beat cross frequency(BCF), mean angular displacement(MAD), dance(DNC), on same sample semen. The DNM of KNC semen sample was variable kinematics after 30 min of incubation. Also, the linearity(LIN) and straightness(STR) was significantly decreased(p < 0.05) from 60 min of incubation. In conclusion, the AI within 30 min after thawing of frozen semen can be an effective method for obtaining high fertility rate in KNC reproductive program.

  • 본 논문에서는 배전 공가설비인 통신케이블 및 기타 통신설비의 관리에 있어 종합적인 정보를 제공할 수 있도록 하는 Web GIS시스템을 구현하였다. 현재 우리나라의 통신망은 세계적으로 관련 컨텐츠 사업의 시험무대라고 일컬어질 정도로 광범위하고 빠른 네트워크를 구성하고 있다. 이러한 빠른 통신망의 확장은 에너지의 근간인 전력망을 활용하고 있기에 가능하였다고 해도 과언이 아니다. 바로 기존 전력설비에 수많은 통신 회선이 공가 되어 운영되어 질 수 있었기 때문이다. 이는 공익성을 우선시하여 운영되어지고 있는 전력사업과 그동안 정보통신사업 육성이라는 정부시책이 맞물려 통신사업자의 빈번한 공가설비 신설 요청이 있었기 때문에 가능하였다. 무엇보다 통신사업자들의 무분별한 경쟁으로 최근 무단 공가설비가 늘어남으로써 전력회사는 통신공가설비관리에 많은 어려움을 겪고 있다. 이러한 문제점을 해소하기 위해 본 논문에서는 GE에너지사의 SIAS(Samllworld Internet Application)를 이용하여 기존에 한국전력에서 운영하고 있는 NDIS(New Distribution Information System)공가 관리 시스템과 상호연동 될 수 있도록 해주는 Web GIS 기반의 배전 공가설비 정보관리 시스템 개발에 관하여 연구 하게 되었으며 이를 운영함으로써 각 통신 사업자들 간의 정보공유와 무단 통신 공가 설비의 근절 및 보다 효율적인 공가설비 운영이 가능 할 것이다.

  • This experiment was conducted to predict the effects of motional characteristics on the fertility of Korean native cattle(KNC) by using CASA technology and in vitro fertilization system. Twenty-six KNC frozen semen straws were obtained from Korean KNC improvement department, livestock improvement main division, national livestock cooperatives federation in Korea. Specimens were allowed to thaw at $37^{\circ}C$ for 30 sec in water bath. Semen analysis was performed on semen image analysis system(SIAS, Medical supply, Korea) adjusted to the gate settings and used the semen droplet ($5{\mu}l$) placed on Makler counting chamber(Sefi medical instrument, Israel) prewarmed at $37^{\circ}C$. The same person used the same micropipette to fill the Makler counting chamber. A total of 150 or more of sperms were analysed in each specimen by a single trained person by scanning at least 5 to 10 fields. The oocytes collection, in vitro maturation, IVF, in vitro culture and determination of the cleavage rate were performed by the technique, as described by Hwang et al (1997). Statistical analysis was done by linear regression with use of the Sigma plot program on a IBM personal computer. The cleavage rate in vitro fertilized oocyte was significantly correlated(P<0.05) with MOT, VCL, VSL, VAP, ALH, BCF and MAD, but not CON, LIN, STR, WOB, DNM, DNC and HYP in regressional analysis. The results show that some kinematic characteristics of frozen-thawed semen by CASA can be predict the fertility in in vitro model system.

  • 현재 한국전력에서는 신배전정보시스템(NDIS : New Distribution Information System)이라는 배전분야의 전력설비 설계 및 유지 보수를 위한 통합시스템을 운영하고 있다. 이는 독점적으로 전력설비의 신규수용 및 유지보수를 하는 우리나라의 구조상 관련 업무를 하는 기술계직원들에게 있어 해당 시스템에 대한 숙련된 지식이 무엇보다 중요하다. 하지만, 이를 위한 교육에 있어서는 현재 한국전력 산하 교육기관인 'KEPCO Academy'의 교육과정 신청을 통한 오프라인 방식으로 교육이 진행 되다보니 관련 기술계 직원들을 위한 접근성 및 효율성이 많이 부족한 것이 현실이다. 따라서 해당 시스템 활용을 위한 보다 개선된 방식의 손쉬운 접근성을 보장해주는 효율적인 설계 시뮬레이션 교육시스템의 필요성을 인식하게 되었다. 이를 위해서 본 논문에서는 NDIS 시스템의 보다 빠른 적응과 응용력을 높이기 위하여 로컬기반의 NDIS 설계시스템을 Web을 통해 구현하고 해당 시스템을 통해 설계연습 및 결과에 대한 피드백을 받을 수 있도록 해주는 교육용 시뮬레이션 시스템개발에 관한 연구를 하게 되었다.
