목적 : 본 연구의 목적은 시각장애 청소년의 일상생활활동에 대한 경험과 어려움을 탐색하여 작업치료가 필요한 주요 영역을 파악하고, 작업치료에 대한 인식 수준을 확인함으로써 향후 작업치료 서비스 제공을 위한 기초자료를 마련하는 데 있다. 방법 : 2023년 8월 15일부터 10월 31일까지 계통추출방식을 통해 선정된 시각장애 청소년 6명을 대상으로 반 구조화된 심층면담을 실시하였다. 면담은 작업치료 실행체계 4판에 근거한 기본적 일상생활활동, 수단적 일상생활 활동, 작업치료 인식으로 구성하여 총 4회기, 회기당 60분씩 진행하였다. 수집된 자료는 현상학적 연구방법인 콜라 이지(Colaizzi)의 분석 방법을 적용하였으며, 질적 연구의 신뢰도와 엄밀성을 확보하기 위해 질적 연구 보고 지침 (COREQ: Consolidated Criteria for Reporting Qualitative Research)을 준수하였다. 결과 : 시각장애 청소년은 기본적 일상생활활동에서 시각 보상과 환경수정을 통해 수행이 가능하였으나, 타인의 인식으로 인해 심리적 위축을 경험하였다. 수단적 일상생활활동에서는 대부분의 영역에서 어려움을 보고하였으나, 전자기기와 소프트웨어를 활용해 일부 활동의 어려움을 보완하고 있었다. 작업치료에 대한 인식은 전반적으로 낮았 으며, 재활서비스는 중증 장애인을 위한 것이라는 인식이 나타났다. 결론 : 시각장애 청소년은 일상생활활동 전반에서 다양한 어려움을 경험함에도 불구하고 작업치료에 대한 인식 은 낮은 수준이었다. 작업치료 서비스 접근성 향상과 적극적인 정보 제공을 통해 시각장애 청소년을 위한 작업치료 서비스의 확대가 필요함을 시사한다.

We present the results of new multi-color CCD photometry for the contact binary XZ Leo, together with reasonable explanations for the period and light variations. Six new times of minimum light have been determined. A period study with all available timings confirms Qian's (2001) finding that the O-C residuals have varied secularly according to dP/dt = +8.20×10-8 d yr-l. This trend could be interpreted as a conservative mass transfer from the less massive cool secondary to the more massive hot primary in the system with a mass flow rate of about 5.37×10-8 M⊙ yr-l. By simultaneous analysis of our light curves and the previously published radial-velocity data, a consistent set of light and velocity parameters for XZ Leo is obtained. The small differences between the observed and theoretical light curves are modelled by a blue third light and by a hot spot near the neck of the primary component. Our period study does not support the tertiary light but the hot region which may be formed by gas streams from the cool secondary. The solution indicates that XZ Leo is a deep contact binary with the values of q=0.343, i=78°.8, Δ (T1-T2)=126 K, and f=33.6 %, differing much from those of Niarchos et al. (1994). Absolute parameters of XZ Leo are determined as follows: M1=1.84 M⊙, M2=0.63 M⊙, R1=1.75 R⊙, R2=1.10 R⊙, L1=7.19 L⊙, and L2=2.66 L⊙.

Lactobacillus sp., Acetobacter sp. and yeast were the most dominant organisms in the EM stock culture and subculture product. Lactic acid bacteria and yeast were able to grow in the fermentation process utilizing seawater. EM treatment of higher concentrations using EM stock culture and EM clay balls (1% or 4%) contributed to an early removal of malodor and an increase of DO in the polluted sediments, indicating an odor-removing activity of EM. The EM treatment of higher concentrations (1% or 4%) somewhat appeared to modify the microbial communities within the sediments, which was confirmed by existence of a few unique fragments from the stock culture based on PCR-DGGE. It still remains to be elucidated that EM cultures were directly involved in the malodor removal and potential sediment bioremediation.

Medicinal soybean, which has been proven to be effective in preventing cancer, heart disease, osteoporosis, and renal failure, is drawing people’s attention among other beans in recent days. This experiment was to examine the concentration of phenolic compounds and isoflavone in 53 kinds of soybeans cultivated and collected in Yeo-Ju, Gyeonggi-do region. The total average content of phenol is 29424.34㎍/g and the most and least phenol were detected in No. 35(814.98㎍/g) and No. 28(353.66㎍/g) respectively. Myricetin was detected the most resveratrol whereas detected the least amount which was less than 0.2% of the total amount among all medicinal soybean samples. Total average isoflavone content was 35910.56㎍/g and the most and least isoflavone was detected in No. 15 (996.66 ㎍/g ) and No.9 (476.18㎍/g )respectively . Malonylgenistin was detecteded the most genistein whereas detected the least amount which was less than 0.02 % of the total amount in all medicinal soybean samples. The result of this experiment is considered to be the basic data of the functional food manufacturing by utilizing domestic medicinal soybean.
