이화명충에 대한 수도의 저항성 요인과 척도를 구명하기 위하여 여러 가지 품종에 접종 및 방사를 하였으며 그 영향에 따라 도체의 주요성분을 분석한 바 아래와 같은 결과를 얻었다. (1) 수도품종간에 이화명충의 유충 생육이 현저하게 큰 차를 나타내었다. 품종에 따른 체중증가량에 있어서도 부화 후 25일에 유충의 체중은 최고 45.77mg, 최저 21.23mg였는데 대체로 Indica type은 Japonica type 보다 유충체중의 증가가 컸다. (2) 수도품종에 있어서 여러 가지 저항성요소중 상관관계를 보면 유충의 생존율은 체중증가, 분화, 피해경율 및 산란선택성들과 정의 상관을 나타내었다. 따라서 유층의 생존율은 이화명충에 대한 도체의 저항성요소의 척도로 이용될 수 있다고 생각되었다. (3) 저항성 및 감수성 품종의 화학적 분석 결과에 의하면 몇몇 저항성요소와 질소함량간에는 정, 그리고 규산의 함량과는 부의 상관을 나타내었으며 특히 유충의 추성에는 질소, 천공성에는 규산의 함량이 관련됨을 알 수 있었고 탄소의 함량과는 유의한 상관을 나타나지 않았다. (4) 유충의 추성 및 천공성도 저항성 척도인 생존율과 정의 상관을 나타내었으므로 저항성은 여러 가지 요소들의 복합적인 작용으로 나타난다고 생각되었다.

The p53 protein was discovered in 1979 as cellular 53-kD nuclear phosphoprotein bound to the large transforming antigen of SV40 virus. $P21^{WAF1/CIP1}$, which has been described as the critical downstream mediator of p53, is known to suppress DNA replication and arrest the G1 cell cycle by quaternary complex with cyclin D, cyclin-dependent kinase(CDK) and proliferating cell nuclear antigen(PCNA). In these days, some studies shows that the p21 can be induced by independent pathways. There are various reports about the expression of p21 (67%.82.4%) in oral squamous cell carcinoma. But these studies are mostly done in malignant tumor not in benign tumor. So we decided to study the expression of p21 in ameloblastoma and the relationship between p53 and p21 as a downstream mediator of p53 in ameloblastoma. We investigated the expression of p21 and p53 with the method of immunohistochemistry. We selected 30 cases of ameloblastoma tissue blocks (acanthomatous type: 5 cases, follicular type: 8 cases, plexiform type: 17 cases) imbedded in paraffin. We used 30 cases of normal gingival tissues and 30 cases of squamous cell carcinoma tissues (SCC) respectively and compared their results with those of ameloblastoma. We made slides with the streptavidin-biotin methods and used monoclonal antibody DO-7 (Novocastra, Newcastle, United Kingdom) as p53 antibody and monoclonal antibody M7202 (DAKO, California, U.S.A.) as p21 antibody. We used Pearson's correlation coefficient to analyse the relationship. The results were as follows: 1. p21 was expressed in ameloblastoma about 30% and this is lower than that of normal gingiva and SCC. 2. In normal gingiva and ameloblastoma, p21 expression was correlated with p53 expression. 3. In SCC, p21 were expressed about 83.3% and this is more than that of p53. But there was no correlation between p21 and p53 expression. We confirmed p21 expression and relation with p53 in ameloblastoma. But, to confirm the function of p21, more studies about p21 expression in malignant ameloblastoma and ameloblastic carcinoma are needed.

This descriptive correlational study was carried to identify the relationship among social support, compliance, and psychosocial adjustment of patients with rheumatoid arthritis. The study was done with 100 rheumatoid arthritic patients who were visited in Outpatient clinic of university hospital in Taegu, Korea from the 23rd of February to the 20th of March in 1998. The Data were collected through person to person interviews which were performed by five researchers. The instruments used for this study were Yu's social support scale(1996), Cho's compliance scale(1987), and Kim's psychosocial adjustment scale(1997). The data was analyzed by using a t-test, Pearson correlation coefficient, ANOVA, and Tukey test with the SAS Program. The results of this study were as follows ; 1. The mean score of social support was 2.76 for 4 full marks, compliance was 3.20 for 5 full marks, and psychosocial adjustment was 2.26 for 4 full marks. 2. Hypothesis 1 : "The higher the social support degree, the higher the compliance degree of the rheumatoid arthritis patient". It was supported(r=0.54, p<0.001). Hypothesis 2 : "The higher the compliance degree, the higher the psychosocial adjustment degree of the rheumatoid arthritis patient". It was supported(r=0.34, p<0.001). Hypothesis 3 : "The higher the social support degree, the higher the psychosocial adjustment degree of the rheumatoid arthritis patient". It was supported(r=0.24, p<0.05). 3. In general, the spouse group compared to other groups was demonstrated as the most dependable group for patients to trust and expect support. And the sons and daughters group was shown higher than other groups in terms of social support(F=4.19, p=0.01). There was no difference in terms of compliance in degree. In the degree of psychosocial adjustment the highly educated group(more than high school) is a little higher than the lowly educated group(F=3.08, p=0.03). In the costs of medical care, the group that could afford was significant higher than the group which could not afford results in terms of the psychosocial adjustment degree(F=3.99, p=0.01). The outcome of this study is that the social support that related rheumatoid arthritic patients had an effect on the following compliance, and the following compliance helps psychosocial adjustment of patients. It also shows that social support related psychosocial adjustment. Therefore, to increase the level of psychosocial adjustment of rheumatoid arthritic patients, it will be effective in supportive nursing intervention to improve social support and compliance.

다짐 에너지 변화(變化)에 따르는 화강풍화토의 입도변화(粒度變化) 및 파쇄량(破碎量)이 투수성(透水性)에 미치는 영향에 대해 연구하였다. 토립자(土粒子)의 파쇄(破碎)는 토립자(土粒子)의 표면적비(表面積比)($S_w{^{\prime}}/S_w$)로서 나타냈고, 다짐에너지를 변화(變化)시키면서 실시한 다짐 시험결과(試驗結果) 만들어진 시료(試料)에 변수위투수시험을 행(行)하여 투수계수와 최적함수비(最適含水比)와의 관계를 조사(調査)하였다. 그 결과(結果) 다음과 같은 사항을 알 수 있었다. (1) 다짐에너지의 증대(增大)에 따라 파쇄(破碎)가 커지고 간극비(間隙比)가 감소되고 건조밀도는 영공극곡선(零空隙曲線)에 평행(平行)하게 증대(增大)된다. (2) 표면적비(表面積比)는 다짐회수에 관계없이 $S_w{^{\prime}}/S_w=0.33(P)^{0.96}$로 표시(表示)할 수 있다. (3) 입자파쇄(粒子破碎)가 가장 크게 일어나는 입경(粒徑)은 0.5~1 mm 범위이다. (4) 최적함수비(最適含水比) 상태에서 투수계수 K와 간극비함수(間隙比函數) $\frac{e^3}{1+3}$와의 관계는 양면대수지상(兩面對數紙上)에서 직선 관계가 성립(成立)한다. (5) 최적함수비(最適函數比) 상태에서 다짐에너지가 증가(增加)되면 200번(番)체 통과량(通過量)은 거의 직선적으로 증가(增加)되며 표면적비(表面積比)의 증대(增大)는 투수성(透水性)의 저하(低下)를 갖고온다.

돼지고기를 전기그릴($EG;\;260^{\circ}C$, 5분) 및 전자렌지(MW, 6분)를 이용하여 조리 한 후 일정기간 냉장(0-14일), 냉동(0-90일) 보존한 시료와 이를 MW(1 min)로 재가열한 시료의 변이원성, 지질과 산화도(TBA), 및 육조직(SEM)을 연구하였다. S9 mix를 첨가하지 않은 상태에서 냉장 및 냉동 저장 기간에 따른 변이원성 유발 정도는 저장 기간이 증가함에 따라 변이원성이 증가하였고, 대사활성물질을 첨가했을 때 더 높은 변이원성을 나타내어 간접변이원이 더 많이 존재함을 확인하였으며, MW 재가열 처리 시는 더 높은 변이원성을 나타내었다. MW(6 min)로 조리했을 때 EG로 조리한 것보다 변이원 유발 가능성 면에서 보다 안전하다고 할수 있으나 냉동저장하고 재가열시는 변이원성 유발 가능성이 보다 높다고 사료된다. 변이원성과 과산화지질 생성간의 상관관계는 대사활성물질을 첨가하지 않았을 때 냉장 저장시 r=0.85, 냉동 저장 시 r=0.86이었고, MW 재가열하였을 때 냉장 저장 시 r=0.98, 냉동 저장 시 r=0.83으로 냉장 저장이 더 높은 상관관계를 나타내었다. SEM을 이용하여 육조직을 관찰한 결과 MW로 조리한 시료 및 MW로 재가열한 시료에서 더 많은 수증기 통로가 관찰되었다.

일반적으로 최대평탄 하프밴드 필터들은 다른 필터들에 비해 넓은 주파수 영역을 가지고 있다. 이것은 필터의 주파수 응답을 직접적으로 제어하기 위한 필터 차수의 여분이 없이 단지 $z={\pm}1$에서 최대 가능한 제로 수를 갖도록 설계된 것으로 독립된 파라미터가 없기 때문이다. 본 논문에서는 천이 대역폭 직접 제어가 가능한 FIR 하프밴드 필터들의 설계를 위한 새로운 방법을 제안하였다. 제안된 방법은 필터의 0번째 계수인 $h_0$를 파라미터화한 일반화된 라그랑지 하프밴드 다항식(g-LHBP)을 기반하고 있으며, $h_0$를 제어함으로써 요구되는 주파수 응답을 갖는 필터를 설계하는 방식이다. 이때 $h_0$는 g-LHBP 재귀관계의 이론적 분석을 통하여 천이대역의 경사도 파라미터로 모델링하였다. 또한, 이 방식은 요구된 필터 특성(:천이대역의 경사도와 대역 평탄도 사이의 균형) 선택과 관련된 설계 파라미터들(:필터 계수들)의 직접적인 계산을 위한 명확한 공식을 제공한다. 설계 예시들은 제안된 방식이 최대평탄 하프밴드 필터들 보다 상대적으로 날카로운 천이대역 경사도를 가진 하프밴드 필터의 설계에 적합한 솔루션임을 보여준다.

자폐적인 아동은 사회적 발달의 기초인 모-아 애착에서부터 왜곡되어 있고 특히 일치적 애착 행동들이 저하되어 있음을 볼 수 있다. 이를 개선하기 위해서는 일치적 행동들의 정상적 발달양상과 관련 요소를 파악하는 것이 선행되어야 하겠기에 자폐군과 정상군 총 20쌍의 모-아 놀이를 비교분석하였다. 그 결과 자폐군의 일치적 행동들은 정상군에 비해 저하되어 있고 발달 경과도 느렸으며 특히 16개월 이상부터는 현저한 차이를 보였다. 일치성과 상관이 있는 어머니의 양육행위는 애정적 표현을 하고 적절한 행동 멈춤을 보이며 아동의 행동을 기다려주는 것이었다. 모-아 상호집중의 저해요소는 지시적이고 간섭하고 학습중심적인 어머니의 놀이 행위와 아동의 무관심, 무반응, 과제수행의 실패 등이었다. 그러나 아동의 수준을 고려해 적당히 자극적인 접근을 하였을 때 상호집중이 유발되고 지속되는 것을 볼 수 있었다.

The disease patterns among the Korean was shifted from acute and infectious diseases to chronic diseases. According to the these disease patterns trends, people have concerned about the health promotion and health behaviors. Pender's(1996) revised health promotion model(HPM) is consist of three categories; Individual characteristics and experiences, Behavior-specific cognitions and affect, behavioral outcome. Of these categories, individual characteristics and experiences, this category of variables is considered to be of biological, psychological and socio-cultural personal factors, especially, individual fatigue. Futhermore. these variables constitute a critical core for nursing intervention, as they are subject to modification through nursing actions. But there is no few the research of the relationship between the fatigue and health promotion. Therefore, the purpose of this study is to investigate the correlation between the fatigue and health promoting life style among a rural college students. Additionally, this descriptive correlational study identified the relation of demographic factors and fatigue, health promoting life style. From June 20 to 26, 1998, a convenience sample of 270 college students completed the questionnaire of the fatigue and health promoting life style profile which were developed by the Yoshitake(1978) and Walker, et al.(1987), respectively. The descriptive correlational statistics, mean, t-test, ANONA, Pearson correlation coefficient were used to analyze the data gathered with SAS pc+ program. The results were as it follows: 1. The average fatigue score of the subjects was $64.93{\pm}12.89$. Fatigue scores by subcategory were physical symptoms($23.5{\pm}4.87$). psychological symptoms($22.11{\pm}4.66$) and neuro-sensory symptoms($19.32{\pm}5.14$). With the respect to the demographic characteristics of the subjects, there were statistically significant differences between the demographic factors and fatigue, especially, sex(t==3.69 p<0.01), major(t=-2.89 p<0.01). the experience of family illness(t=2.76 p<0.01). 2. The average health promoting life style item score of the subjects was $2.33{\pm}0.33$. In the subcategories, the highest degree of performance was self-actualization(2.94), following interpersonal support(2.81). stress management(2.33), exercise(2.20), nutrition(2.10), and the lowest degree was health responsibility(1.73). There were the significant differences on the learning of health education(t=2.00 p<0.01). religion(F=3.01, p<0.05), circle activity(t=2.07, p<0.05), nutrition control(t=5.25, p<0.01) of demographical factors with the health promoting life style. 3. The correlation between the fatigue and health promoting life style made statistically no significance(r=-0.09731, p>0.05). But there was negative significant relationship between health promoting life style and psychological symptom as a fatigue subcategory(r=-0.15721, p<0.05). The self-actualization showed negative significant correlation with all fatigue subcategory. The health responsibility showed significant relationship with total fatigue(r=0.13050. p<0.05). For further research, it suggests to replicate the correlational and causal study between the fatigue and the health promoting life style using the another fatigue scale which is able to measure the subjective and objective fatigue degree. And it needs to develop the nursing intervention program for maintaining and promoting the health behavior as well as for decreasing the college students's fatigue.
