This study of nurse educator's attitudes which found aspects of professional nursing was carried out from September 10 to 30, 1977. Subjects were 205 respondents from a total population of 314 nurse educators from the level of instructors to professors in all the diploma (post high school 3 year), professional junior college (3 year level) and university (4 year) nursing schools in Korea. Specific objectives were to determine their attitudes about the 1. social position of nursing as a profession, 2. nurses attitudes towards their word, 3. factors influencing the development of nursing, 4. the future of nursing, 5. nursing educational problems, 6. their own educational position's intrinsic job satisfaction and 7. their salary and benefits. The instrument used was a questionnaire developed from consultations with nursing educators and sociologists, and based on earlier. worts by Burke (1976), Mason (1974) and Hong 1969. Data were analysis by computer using one-way analysis. Statistically significant findings included the following; 1. Responses were positive toward all seven aspects of professional nursing. 2. Compared to diploma nursing school staff whose responses were positive, professional and university school faculty response toward the social position of nursing were neutral. 3. Faculty with clinical experience of 10 to 19 years were most positive in their responses about nurses' attitudes towards their work. In all three types of schools, in comparison to professors, associate professors' responses were more positive about nurses' attitudes toward their work. Faculty with longer clinical experience expressed high agreement with statements about factors which influence the development of nursing. Without any differences between school, all faculty had positive attitudes towards the future of nursing, the younger the staff member, the more positive were the responses. 4. faculty in diploma schools and those with 10 to 19 years clinical experience expressed high agreement with statement about nursing educational problems, 6. their own educational position's intrinsic job satisfaction and 7. their salary and benefits.

Responses showed general satisfaction with intrinsic aspects of teaching in all school. Associate professors were positive about satisfaction with salary and other benefits but full professors' responses were neutral.

The Green's equivalence relations have played a fundamental role in the development of semigroup theory. They are concerned with mutual divisibility of various kinds, and all of them reduce to the universal equivalence in a group. Boolean matrices have been successfully used in various areas, and many researches have been performed on them. Studying Green's relations on a monoid of boolean matrices will reveal important characteristics about boolean matrices, which may be useful in diverse applications. Although there are known algorithms that can compute Green relations, most of them are concerned with finding one equivalence class in a specific Green's relation and only a few algorithms have been appeared quite recently to deal with the problem of finding the whole D or J equivalence relations on the monoid of all $n{\times}n$ Boolean matrices. However, their results are far from satisfaction since their computational complexity is exponential-their computation requires multiplication of three Boolean matrices for each of all possible triples of $n{\times}n$ Boolean matrices and the size of the monoid of all $n{\times}n$ Boolean matrices grows exponentially as n increases. As an effort to reduce the execution time, this paper shows an isomorphism between the R relation and L relation on the monoid of all $n{\times}n$ Boolean matrices in terms of transposition. introduces theorems based on it discusses an improved algorithm for the J relation computation whose design reflects those theorems and gives its execution results.

Background : There is lack of studies on the effects of the bag-carrying style on the shoulder muscles and body alignment in adults with rounded shoulder posture (RSP). Objective: The purpose of this study was to investigate the effects of various bag-carrying styles on muscle tone, muscle stiffness and spinal alignment in 20 adults with RSP as they were walking on a treadmill. Design : Crossover Study Design. Methods: A subject performed treadmill walking for 15 minutes at a speed of 4 ㎞/ｈ while carrying three different types of bags: a backpack, a cross bag, and a shoulder bag. Results : The results showed that the main effect of timing was observed in the muscle tone for all the variables and in muscle stiffness only for the upper and lower trapezius muscles. As for the main effect of timing, the muscle tone of the upper trapezius and the pectoralis major significantly increased in all conditions, while the muscle tone of the lower trapezius significantly decreased in all conditions. The muscle stiffness of the upper trapezius significantly increased in all conditions, while the muscle stiffness of the lower trapezius significantly decreased in all conditions. As for the spinal alignment, the dimple distance data values significantly decreased for the cross-bag style. Conclusions : This study demonstrated that walking with a heavy bag, regardless of the bag-carrying style, increased muscle stiffness around the shoulders in adults with rounded shoulder posture, and walking with a cross-bag also induced changes in spinal alignment.

4년생 인삼의 저장근에 함유된 일반 화학성분, 유리당 및 사포닌 성분을 수확 시기별로 조사하고 그 변화 양상을 검토하여 4년생 인삼의 최적 수확기 선정을 위한 기초자료 제공을 목적으로 한 본 실험의 결과를 요약하면 다음과 같다. 1. 4년생 인삼의 전 생육기간 중 조단백 함량은 지상부 출현기인 4월이 20.77%로 가장 높았고, 지상부 전개가 완료된 6월이 13.13%로 가장 낮았으며, 8월 이후에는 17% 수준으로 함량의 변화가 일어나지 않았다. 2. 조지방 및 조섬유 함량은 조단백과 반대의 양상으로 개화기인 5월에 최대치를 나타내었다. 3. 총당은 전 생육기간 중 60-71%의 함량범위로 존재하여 전체성분 중 가장 높은 함량을 나타내었고, 지상부 생육이 완료된 6월이 71% 수준으로 가장 높았으며, 개화기인 5월이 60% 수준으로 가장 낮았다. 4. 인삼 저장근의 유리당 함량은 지상부 출현기인 4월에 20.40%로 최대치를 보였으나, 개화기인 5월에는 11.89%로 전생육시기 중 최소의 함량을 나타내었다. 5. 유리당 중 가장 함량이 높은 sucrose의 변화(10.96-19.60%) 양상은 전 수확기간 중 총 유리당의 변화(11.89-20.40%) 경향과 유사한 양상을 나타내지만 fructose의 함량 변화와는 서로 상반된 양상을 나타내줬다. 한편 유리당 중 glucose와 maltose의 함량은 전 수확기간 중 통계적 차이가 인정되지 않았다. 6. 조사포닌과 총 ginsenosides함량은 개화기인 5월에 각각 7.60% 및 4.09%로 기타 수확시기에 비해 월등히 높았으며, 그 외의 시기에는 통계적으로 유의한 차이가 인정되지 않았다. 따라서 4년생 인삼에서 성분적 특성만을 고려할 경우 개화기인 5월이 가장 유리하였다 그러나 개체당 함량은 10월이 가장 높게 나타났다.

The digital electronic switching system has some problems, when this system processes OAM(Operation, Administration And Maintenance) messages about the fault, the traffic, the account, and the performance, etc. , at the present. Therefore, we studied on Methods that could process OAM messages out of all digital electronic switching systems and, first of all, developed the MGS (Message Gathering System) to be able to accept and process the fault message of OAM messages out of all digital electronic switching systems in real time.

We consider the class (equation omitted) of all k-degenerate graphs, for k a non-negative integer. The class (equation omitted) and (equation omitted) are exactly the classes of totally disconnected graphs and of forests, respectively; the classes (equation omitted) and (equation omitted) properly contain all outerplanar and planar graphs respectively. The advantage of this view point is that many of the known results for chromatic number and point arboricity have natural extensions, for all larger values of k. The purpose of this note is to show that a graph G is (P$^3$)-realizable if G is planar and 3-degenerate.

Several authors find all the derivations of an algebra [1], [3], [7]. A Weyl type non-associative algebra and its sub algebra are defined in the paper [2], [3], [10]. All the derivations of the non-associative algebra $\overline{WN_{0,0,s1}$ is found in this paper [4]. We find all the derivations of the non-associative algebra $\overline{WN_{0,s,01}$ in this paper [5].

Simulation of naturally appearing enamel in fixed prosthodontics could be achieved with all ceramics. The purpose of this study was to investigate the stain resistance of 4 different all ceramics materials (In-ceram, IPS Empress, Celay, Vintage). Forty specimens were prepared using manifacture's instruction and the samples were divided into two groups. The specimens for one group were glazing and those for other group were ground to remove the glazing layer. All specimens were immersed in methylene-blue for 24hours. The color values for each specimen was measured with colorimeter (Mode Tc-6Fx, Tokyo Denshoku Co.) prior to and after immersion in methylene-blue. The following conclusions were drawn from this study. 1 The stain resistance of glazing ceramics was higher than that of unglazing ceramics. 2. The changes of ${\Delta}E^*$\;and\;L^*$ values were revealed in Vintage and unglazing Celay. 3. The changes of $a^*$ values were revealed in unglazing vintage, Celay, In-ceram. 4. The changes of $b^*$ value were revealed in Vintage, IPS Empress and unglazing Celay.
