"Yut Kang Jung" is a kind of Korean traditional cookie. The purpose of this study is to examine the effects of various kinds of syrups and cooking methods of Yut Kang Jung. The quality of Yut Kang Jung was evaluated by sensory and Instron machine test. The results is as follows; 1. The Recipe of the best Yut Kang Jung is this: White sesame 120g, sugar syrup 40g, and crude maltose watery 50g are used. Mixing sugar syrup crude maltose watery boiling for 4 min, in temperature $105^{\circ}C$. The sugar density after boiling was 86%. 2. Yut Kang Jung made by sugar syrup and crude watery maltose got the best result in sensory best. 3. Yut Kang Jung made by crude watery maltose got the best result in mechanical test. 4. The comparison between the sensory test & mechanical test were as follow; The hardness in the mechanical test was comparable with hardness & fracturability in the sensory test, and the chewiness in the mechanical test was comparable with flavor, adhesiveness, fractur ability in sensory test.

Urgent reduction is required in cases of traumatic hip dislocation to reduce the risk of avascular necrosis of the femoral head. However, in cases of femoral head fractures, the dislocated hip cannot be reduced easily, and in some cases, it can even be irreducible. This irreducibility may provoke further incidental iatrogenic fractures of the femoral neck. In an irreducible hip dislocation, without further attempting for closed reduction, an immediate open reduction is recommended. This can prevent iatrogenic femoral neck fracture or avascular necrosis of the femoral head, and save the natural hip joint.

Severe chronic coughing infrequently causes rib fractures and these fractures belong to Stress fracture and these rib fractures are given the term of "cough fractur". Cough fracture usually occurs in one rib and in the middle of the rib between the costochondral junction and the costal angle. The case is a report about a young woman with multiple rib fractures which were caused by severe coughing. The Chest PA and Rib series test were normal but Rib fractures were founded by Bone scan test. Treatment was Herb-medication, rest and restriction of work and symptoms were reduced.

7072Al 을 기지로하고 W 섬유를 강화재로 사용하여 진공 hot press 에서 복합재료를 제조한 후 시간을 변수로 열처리하여 처리시간에 다른 계변층의 변화와 이에 따른 기계적 성질의 변화를 비교 검토하였다. 각종기기(SEM, XRD 등)를 사용하여 계면층을 분석한 결과 처리시간이 10시간까지는 계면층의 변화는 미미하였으나 10시간을 초과하면서 계면층은 현저히 성장하기 시작했다. 이 계면층은 취성이 있는 $WAl_{12}$ 및 $WAl_5$의 화합물로 확인되었다. 이 화합물층의 생성은 기계적성질의 저하를 초래화고 있었다. 즉 인장강도가 처리시간이 10시간을 초과하면서 현저하게 감소하고 있었다. 또한, 파괴양상은 계면화합물층으로 인해 열처리한 후에는 열처리전의 연성파괴에서 취성파괴로 변화되었다.
