Among the general characteristics of the subjects, needs of love and relatiohship wasn't significanlty different. 3. Among the general characteristics of the subjects, needs of meaning and object was significantly different according to two factors : age(F=7.260, p=0.001), religion(F=5.275, p=0.001). Higher needs of meaning and object was possessed by the older than the younger, by the one who have religion than the other. 4. Among the general characteristics of the subjects, four factors made a significantly difference to needs of forgiving : sex(t=-2.851, p=0.006), age(F=8.201, p=0.001), religion(F=6.928, p=0.000), disease(t=2.327, p=0.024). Higher needs of forgiving was possessed by man than woman, by the older than the younger, by the one who have religion than the other, by the one who have disease than the other.

본 논문에서는 4G 이동통신 시스템 기반 기술인 MIMO (Multi-Input Multi-Output) 시스템에서, 채널 정보를 이용할 때, 결합 송수신 최적화 형태를 유도 하였다. Lagrange Multiplier Method를 이용하여 일반적인 SINR(Signal to interference and noise ratio)의 극대값을 유도하는 과정에서, 결합 송수신 형태를 수식적으로 유도하였고, 이를 ITU-R M.1225 채널 모델에 적용하여 시뮬레이션 하였다 또한 채널에 대한 정보가 없을때, 시공간 다이버시티를 얻을 수 있는 STBC(Space time Block Coding)의 MIMO 시스템과 비교하였다.

Washed rice was coated by spraying aqueous dandelion (Taraxacum officinale) extracts at 20, 30, 40 'Brix and dried at room temperature. The coating procedure was conducted 5 mL/min for 10min. Property changes in the dandelion coated rice and un-coated cooked rice were observed during 2 days of storage. Increasing the coating concentration was associated with lower color values (L, a value) and moisture contents. Sensory and texture properties generally decreased in the cooked rice coated with dandelion more than the control (non-coated rice). But, D-20(20 °Brix of the dandelion concentration) resulted in better textural properties and s ensnry scores for hardness and overall acceptability in cooked rice. Compared to the control, the washed rice roated with 20 °Brix for 0 and 2 days showed better quality in sensory activities, a lower gel consistency and better textural activities. It was concluded that the optimum coating ration of rice and added dandelion extract for cooking were 20 °Brix and 5% respectively, in proportion to the total weight of raw rice.

This paper is to evaluate practically the techniques and materials of repair for high strength concrete elements with fire damages as well as to investigate the structural behavior of beams according to pre- or post-repair after fire-damages. For this purpose, flexural specimens with high strength concrete were exposed to high temperatures by the ISO 834 specification. After natural cooling and post-fire-curing in a natural environment for 1 months, 6 specimens were loaded to failure after they were repaired with polymer cement mortar for 1 month curing.

구토 후 발생한 토혈을 주소로 내원한 환자에서 좌측 늑막 삼출 동반 시 식도 파열의 가능성을 고려하여 흉수 천자 및 지속적인 흉부 단순 촬영의 추적관찰이 필요하며 식도 파열이 배제된 후 환자의 생체 징후 및 토혈 양을 파악하여 내시경 검사 시기를 신중히 결정하는 것이 좋을 것으로 생각된다. 본 증례는 토혈을 주소로 내원하여 Mallory-Weiss 증후군 의심 하에 내시경을 통한 치료 시행 후 추적 관찰에 의해 진단된 Boerhaave 증후군을 경험하였기에 보고하는 바이다. Boerhaave's syndrome is a spontaneous perforation of the esophagus most commonly resulting from a sudden increase in intraesophageal pressure combined with negative intrathoracic pressure caused by straining or vomiting. Surgery should generally be performed within 24 hours because mortality approached 30 to 50 percent in which surgery was delayed. Therefore, early diagnosis and prompt surgical repair are critical for survival. We have experienced a case of Boerhaave's syndrome in a patient presenting with hematemesis with left pleural effusion without any signs or symptoms of pneumomediastinum or pneumothorax.
