In this paper, we proposed the position detecting system of obstacle which aids the blind to supply position information of obstacle for understanding surroundings and safe walking. The proposed system attaching to the white cane, which radiates an ultrasonic to the 5-direction(forward, upward, downward, left/right side) and measures the distance to obstacle and supplies walking information with the alarm. An obstacle detecting of each sector used ultrasonic and the distance measurement used TOF(Time of Flight) method. This system consists of a distance measurement part, a signal processing/measuring part and an alarm part. The result of experimental testing and performance evaluation, this system detected the obstacle of approximately 3[m] in the forward and left/right side, and height head of the obstacle in the upward, and prominent and a cave-in part of obstacle in the downward. This system provides a sound and vibration alarm to the blind an obstacle information from each direction and distance.

In this paper, we implemented the electronic moving aid system for safe walking of the blind. An obstacle detecting of each sector used ultrasound and a distance measurement used time of flight. The alarm is designed to have a sound and a tactile function that can be selected on an user's convenience. This system can detect an obstacle of upward, forward, downward and optimally warn to the blind with vibration, beep sound by appling warning algorithm on object detection. Experimental testing and performance evaluation have been successfully carried out with a prototype cane, and the experiment shows the capability of the function to detect unknown objects within an assigned distance, under knees, over head height, and crushed puddles.

Purpose: IS prelminary study was designed to assess the clinical variables influencing on the ward atmosphere in psychiatric closed ward and to promote the quality of psychiatric inpatient treatment. Method: 41 psychiatric inpatients were selected in Chung-ju hospital, Konkuk university. Ward Atmosphere Scale(W AS) was used to evaluate patients' perception of ward milieu. WAS score were compared among subgroups with respect to the clinical variables such as duration of admission, frequency of admission, and diagnosis. Results: Significantly, patients who have hospitalized for 1 month to 2 months reported lower score of WAS and patients who have hospitalized for longer than 2 months reported higher score of WAS. The relationship between educated levels and WAS score was not significant. First admitted patients reported significantly lower score of WAS. Bipolar patients reported significantly higher score of WAS and alcohol related patients reported significantly lower score of WAS. Conclusion: The 1st admitted patients, patients with alcohol problem and educated patients were had less satisfied with psychiatric closed ward. Thus, by considering these factors, more specified therapeutic approach and plan should be conducted.

Since the emergence of the term premenstrual syndrome (PMS) in the 1950s, PMS has become an increasingly discussed topic in popular media sources. Thus self management techniques are easily accessed by women through the media or through their peers. Premenstrual dysphoric disorder (PMDD) comprises extremely distressing emotional and behavioral symptoms. Women with PMDD report premenstrual symptoms, primarily mood symptoms, that are severe enough to seriously interfere with their life style and relationships and usually do not respond to conservative and conventional interventions. Although women with PMS are most often seen in primary care or by their obstetricians/gynecologists, the result of recent study suggested a high rate of missed diagnoses. The premenstrual syndromes include the more common PMS, the less prevalent PMDD, and menstrual psychosis. The etiology of PMS and PMDD is still largely unknown. That PMS and PMDD are primarily biological phenomena is underscored by recent, convincing evidence. Therapeutic interventions for PMS and PMDD range from the conservative to treatment with psychotropic medication and, for the more extreme cases, hormonal therapy or surgical procedures.

This studies was carried out to assess antioxidant activity between flavonoid compounds (rutin, qurcetin, luteolin) and maysin(2''-O-6-C-(6-deoxy-xylo-hexose-4ulosyl)luteolin) isolated from corn silks of Zea mays L. Maysin extracted by corn silks was the highest free radical scavenging among flavonoid compounds such as rutin, qurcetin, and luteolin. But, the other flavonoid compounds(luteolin) showed the strongest free radical scanverning activity. In the results of peroxidase activity(POD), maysin don't indicated the remarkable peroxidase inhibiton activities. At the lowest concentration, NBT(Nitro blue tetrazolium) reduction activity of rutin, qurcetin, and luteolin were the low inhibition activities but maysin showed the highest Nitro blue tetrazolium reduction activity. Lipid peroxidase inhibition activities using Thiobarbituric acid(TBA) method, maysin showed the highest lipid peroxidase inhibition in three concentration levels..

미이라병은 Diaporthe/Phomopsis complex에 의해 유발되는병으로 콩 재배기간 중 따뜻하고 습한 환경에서 종자가 성숙되면 감염률이 높아지며 감염된 콩 종자는 외관상 품질뿐만아니라 종자 활력이 저하된다. 미이라병에 대한 연구를 수행하기 위하여 대만에 위치한 아시아채소개발연구센터(AVRDC)의 콩 시험포장에서 미이라병 병징을 보이는 콩 줄기를 채집하고 이로부터 3개의 곰팡이 균주(isolate)를 분리하였다. 배지위에서의 곰팡이 균사의 생육특성, 현미경하에서 관찰된 알파,베타 분생자(conidia)의 모양 그리고 PCR-RFLP 분석으로, 3개의 균주는 Diaporthe phaseolorum var. sojae 으로 확인되었다. 한편, 미이라병 저항성 육종을 위해서는 유전자원과 계통의 검정이 선행되어야 하는데, 인공접종을 위해서 분생자의최적 배양조건을 탐색하였다. 그 결과 배지는 PDA, 온도는24oC에서 잘 배양되었으며, 일장은 암조건에서는 균사체만 유도되고 분생자는 유도되지 않았으며, 24시간과 15시간의 일장에서는 균사체 유도 및 분생자의 유도 정도에 차이가 없었다.또한 잎-줄기와 꼬투리, 두 개의 접종 부위에 따른 미이라병감염률을 조사하였는데, 두 접종 부위에 따른 미이라병 감염정도는 통계적인 유의차는 나타나지 않았으나 잎-줄기에 접종한 개체 보다 꼬투리에 접종한 개체의 종자 감염률이 높은 경향을 보였다. Phomopsis seed decay (PSD) caused by Diaporthe phaseolorum var. sojae (Lehman) Wehmeyer, Diaporthe phaseolorum (Cooke & Ellis) Sacc. var. caulivora Athow & Caldwell, and Phomopsis longicolla Hobbs reduces quality of soybean (Glycine max (L.) Merr.) seed when it is wet and warm condition during seed maturation period. To study of the PSD in Taiwan in March 2008, three unidentified fungal isolates (isolate1, isolate2 and isolate3) were isolated from soybean stems infected with pod and stem blight which is associated with seed decay. Based on their morphological and genotypic characteristics, three isolates were regarded as Diaporthe phaseolorum var. sojae. For PSD assay, we found that the best condition for the fungal isolates growth was on potato dextrose agar (PDA) media at 24°C temperature for 24 or 15 hr photoperiod. Leaf- stem and pods of soybean were inoculated by an atomizer with two isolates among three isolates to investigate PSD infection. In the result of two inoculation parts with two isolates, there was no significant difference in degree of pod infection and seed infection rate (%) between isolate2 and isolate3, but there was a tendency that pod inoculation than leaf- stem inoculation caused higher level of seed infection. These isolates obtained in this study would be applicable to screening of PSD resistant soybean germplasms in the breeding program.

Purpose: Although laparoscopic surgery is widely accepted in the treatment of colorectal cancer, conversion to open surgery is associated with the rate of unfavorable outcomes. The aim of this study was to determine the factors associated with open conversion from laparoscopic surgery for colorectal cancer. Methods: A total of 3,002 patients who underwent laparoscopic colectomy as an initial plan for the treatment of colorectal cancer located from the sigmoid colon to the rectum were retrospectively evaluated between January 2009 and December 2018 at Samsung Medical Center in Korea. Risk factors significantly associated with open conversion were determined using univariate and multivariate regression models. Results: Among the 3,002 patients, open conversion was performed in 120 patients (4%). Age >60 years (adjusted odds ratio [AOR], 2.370), preoperative bowel obstruction (AOR, 2.348), clinical T4 stage (AOR, 2.201), and serum carcinoembryonic antigen level >5 ng/mL (AOR, 2.289) were significantly associated with open conversion. Moreover, mucinous carcinoma was a significantly more frequent histopathologic type than adenocarcinoma (10.0% vs. 3.2%, P<0.001) in the open conversion group with an AOR of 2.549 (confidence interval, 1.259–5.159; P=0.009). Conclusion: The present study presented a novel finding, i.e. mucinous carcinoma as the histopathologic type could be an independent predictive factor for conversion from laparoscopic colectomy to open surgery. Identifying patients with mucinous carcinoma will help stratify the risk of open conversion preoperatively.
