MDCM의 部位別 加工特性을 파악하여 加工適性을 向上시키기 위한 實驗結果는 다음과 같다. 1. 다리외의 모든 MDCM은 수분 56.7-67.5%, 蛋白質 16.3-20.1%, 지방 13.1%-25.8%, 회분 1.1-1.3%, 다리 部位의 脂肪이 25.8%로 높고, 수분이 56.7%, 蛋白質이 16.3%로 낮아 脂肪含量 차이에 의해 組成比가 달랐다. 2. 部位別 加工適性은 皮膚를 제거한 목으로 製造된 MDCM이 가장 높았고, 반면 다리부위가 가장 낮았다. 精肉含量은 높고 脂肪含量이 낮을 때 加工適性은 向上 되었다. 3, 燐酸鹽을 添加할수록 加工適性이 현저히 向上되었고 燐酸鹽과 소금을 混合 添加하였을 때 각각 단독으로 添加하였을 때 보다 인화력의 증가효과는 높았으나 上昇效果는 없었다. 4. MDCM에 gelatin을 添加할수록 乳化力이 減少하고 Collagen 含量이 增加하였다. 5. 總 添加量에 60%의 精肉이 들어있는 patty에서 MDCM의 添加率이 增加하면 加熱水率 保水力이 약간 떨어졌으나 25% 범위의 첨가시 品質變化가 없었다. 1. Moisture content for most parts of MDCM except leg was 56.7%-67.5%, protein 16.3-20.1%, fat 13.1-25.8% respectively. 2. Functional property of MDCM increasing protein content, or decreasing fat content. MDCM from neck without skin had better functional property than MDCM from leg. 3. Sodium tripolyphosphate had a great deal of effect functional property in MDCM. 4. MDCM added with higher concentration of gelatin tended to decrease emulsifying capacity. 5. Patty manufactured with 60% lean meat showed that cooking yield and water holding capacity were influenced by addition level of MDCM.. It was possible to recommended that patty formulation with predicted acceptability was above 25% MDCM.

Fifty two cases of traumatic diaphragmatic injuries that we have experienced from Jan. 1973 to Oct. 1994 were evaluated. The following results were obtained. The age of the patient was ranged from 1 to 74 years. Male was 38 and female was 14 in number with a ratio of 2.7 : 1. The traumatic diaphragmatic injuries were due to blunt trauma in 35 cases(motor vehicle accident 25, fall down 8, press 1, kick by fight 1) and penetrating trauma in 17 cases(stab wound 15, shot wound 1, explosion 1). In the blunt trauma, the preoperative diagnosis of the diaphragmatic injury was possible in 25 out of 35 cases(71%) and in the penetrating trauma, 15 out of 17 cases(88%). In the blunt trauma, the repture site was located in the left in 22 cases(63%) and in the right in 13 cases(31%). In the penetrating trauma, the rupture site was located in the left in 9 cases(53%) and in the right in 8 cases(47%). In the blunt trauma, 20 cases(63%) were treated within 24 hours and in the penetrating, 15 cases(88%) within 24 hours. In the blunt trauma, the herniated organs into the thorax were stomach(7), omentum(6), spleen(6), liver(5), colon(4), small bowel(2) and in the penetrating, stomach(7), colon(6), omentum(3), liver(2), and spleen(1) were herniated. Injury severity score(ISS) of 35-blunt trauma ranged from 11 to 66 with mean value of 30.6. Mean ISS of survivors and nonsurvivors was 27.6 and 52.7 respectively. The diaphragmatic repair of 49 cases was performed with thoracic approach in 23 cases, thoracoabdominal approach in 7 cases and abdominal approach in 19 cases, and 3 cases were not operated. The postoperative complication and mortality were developed in 16 out of 49 cases(33%) and in 5 cases(9.6%) respectively, and the causes of death were hypovolemic shock(1), combined head injury(2), asphyxia(1), and pulomnary edema and renal failure(1). In conclusion, the injuries of the diaphragm should be suspected in all patients with severe blunt trauma or penetrating injuries at thorax and upper abdominal area near the diaphragm. All of the cases had associated injury and most of deaths were related to the severity of associated injuries.

With a view to examining the habit and method in which old people maintain and improve their health, we consulted 551 men and 444 women who were over 65 years old, and concluded as follows: 1. Habit of eating It's been revealed that most of the old people keep a regular eating hour, control the quantity of meal or eat a little food, and prefer vegetables to meat. 2. Mental health Old people feel the necessity for mental health and most of them (about 80%) keep good mental health without becoming pessimistic. Their chief concenrs have turned out to be about their sons and daughters and their own health and finance. 3. Managing Good Health It has been revelaed that old people do not possess any special kind of secret to keep good health but taking plenty of rest, regular meal, and proper exercise, and many of them (about 60%) have been shown to eat invigorant food that they can easily get around their living area. 4. Physical Functions It has been revealed that many old people are conscious of some symptoms about their parts of body and about to percent of them suffers from neuralgia. Some measures like medical aid especially for old people need to be taken as soon as possible. As we have found that the health-keeping method of old people consists plenty of rest, proper exercise, and appropriate nutrition, we can conclude that the recreatonal and culture facilities and programs for keeping old people in good health should be developed. It is also necessary to study food that contribute to their health and develop ways to get rid of the stresses to which they are exposed in their daily life. Presides, it is natural that government found an administrative department to deal with these matters effectively.

The present study was to assess the in vitro viability and sexing rate of bovine embryos. Blastocysts were harvested on day 7~9 day after insemination(in vitro and in vivo), and the sex of the embryos was examined using the LAMP method. Embryo cell biopsy was carried out in a $80{\mu}l$ drop $Ca^{2+}$, $Mg^{2+}$ free D-PBS and, biopsied embryos viability were evaluated after more 12 h culture in IVMD culture medium. The formation of recovered embryo to expanded and hatching stages had ensued in higher of sexed embryo in vivo than in vitro (100% vs. 89%, p<0.05), and in vitro, the rates of degeneration after sexing were significantly (p<0.05) higher in vitro than in vivo(11% vs. 0.0%). The rates of the predicted sex were female 61% vs. 56%, and male 39% vs. 44% in vivo and in vitro, respectively. The rates of survival following different biopsy methods were seen between punching and bisection method in vivo and in vitro (100% vs. 89% and 100% vs, 78% respectively). Biopsy method by punching was significantly (p<0.05) higher than bisection between produced embryos in vivo and in vitro. The present data indicate that with microblade after punching for embryo sexing results in high incidence of survivability on development after embryo biopsy. It is also suggested that LAMP-based embryo sexing suitable for field applications.
