동해 西南海域의 식물플랑크톤의 분포와 환경요인의 상관관계를 연구하기 위해 Canonical Correlation 분석을 실시하였다. 조사된 7가지의 환경요인 가운데서 식물플랑크톤의 분포에 가장 중요한 영향을 끼친 것은 봄철에 수온 가을철에 염분이었다. 이 두가지 환경요인의 계절적인 변화와 연구 수역의 해양 물리학적 현상에 대하여 논하였다. 쿠로시오 指表種들과 Protoperidinium 속의 두종들은 높은 수온 및 높은 염분과 量的인 연관성을 나타낸다. 소형 우주주조류와 無色 質鞭毛 類들은 낮은 수온역을 선호하여, 서로 규산염에 대해 생태적인 경쟁 관계에 있는 것으로 보인다. 그 결과 無色 質鞭毛類가 보다 규산염농도에 대하여 더 낮은 값 을 보인다. 질소 고정 난조류의 一種인 Oscillatoria erythraea 는 인산염 농도와 陽 的인 연관성을 나타내었다.

국내에서 터널 설계 시 널리 사용되는 RMR 분류법과 Q-system은 모든 암종에 대해 동일한 배점 체계를 적용하기 때문에, 지역적인 지질학적 특성을 반영할 수 없으며 암반의 공학적 이방성을 충분히 표현하지 못한다. 본 연구에서는 암종별 지질학적 특성차에 의한 각 RMR 항목의 중요도를 살펴보기 위하여, 퇴적암, 화강암, 천매암을 기반암으로 하는 터널을 대상으로 막장관찰자료에 대해 정준상관분석을 실시하였다. 분석결과에 의하면 암종의 변화에 따라 전체 RMR배점에서 각 인자가 차지하는 영향은 서로 큰 차이를 보였다

This paper has aimed to identify marketing variables which affect physicians' prescription of drug. Based on a literature review this paper derives the three factors (indirect commercial source, direct commercial source, academic information source) of information sources that physicians rely on for medicines, the three factors (research supporting activity, marketing supporting activity, medicine information supporting activity) of promotion activities physicians prefer, and the four factors (indirect quality of medicine, direct quality of medicine, experience of using medicine, price and design of medicine) of prescription criteria physicians use. Then it investigates using canonical correlation analysis whether or not physicians' prescriptions are affected by the information sources, the promotion activities, and the type of physicians. From the canonical correlation analysis this paper derives the meaningful three canonical functions of prescription for drugs. The first function explains the prescription which is insensitive to marketing activities, the second function does the prescription which is sensitive to them, and the final function does the prescription which is not affected by them.

본 연구는 원격탐사의 수치화상분류에 적용된 바 없는 정준상관분석(Canonical Correlation Analysis)기법을 무감독분류한 위성화상데이터에 적용하여 토지피복분류하는 새로운 방법을 개발하는 것을 목적으로 한다. 개발된 분류기법은 기존의 분류기법인 최대우도분류기법에 비해 분류기준용 표본데이터 선정이 용이함을 알 수 있었다. 즉, 정준상관분석에 의한 분류결과는 분류기준용 표본데이터의 선정위치에 거의 영향을 받지 않는다. 또한 무감독분류 후 정준상관분석에 의해 결정된 각 군집의 토지피복은 최대우도분류를 위한 사전정보로 활용정보로 활용가능하다. 동일한 분류기준용 표본데이터 사용시, 무감독분류 후 정준상관분석에 의한 분류가 최대우도분류보다 분류정확도가 우수하였다. 이상과 같은 결과로 판단해 볼 때 연구에서는 시도된 분류기법은 원격탐사의 분류기법 분야에서 실용화 될 수 있으며, 나아가서는 GIS 데이터베이스 구축에 중요한 역학을 할 수 있을 것이다.

This study was designed to investigate the correlation between perceived TQM performance and job satisfaction of dietitians. The objective of the study is to help the management of foodservice by providing a direction which will elevate perceived TQM performance of dietitians and presenting plans which will ensure effective foodservice management. The survey sample was dietitians (n = 308) who were charged with foodservice management. The questionnaires requested information about demographics self-perception of TQM importance and performance levels, and Job satisfaction. According to the TQM importance and performance analysis, the level of performance was typically high in TQM items recognized as important by dietitians and low in areas where the recognized level of importance was low. Analysis was conducted on the job satisfaction according to demographic characteristics. The level of satisfaction in terms of salary and promotion increased relatively for those working in the industries and those who were older, married, and full-time employees with longer careers. The lesser the number of working hours, the higher their satisfaction levels were. Canonical correlation analysis between TQM performance and job satisfaction indicated higher canonical correlation (canonical correlations coefficient: 0.59). In conclusion, TQM performance-job satisfaction showed higher canonical correlation. When information exchange via network is made possible and more external customer recognition is gained, it increases the level of job satisfaction. The above results suggest that further research on the scope of TQM performance is thoroughly needed and continual training is necessary for foodservice managers.

This study was designed to investigate the correlation between perceived TQM performance and organizational culture of dietitians. The objective of the study is to help the management of foodservice by providing a direction which will elevate perceived TQM performance of dietitians and presenting plans which will ensure effective dietitians. Questionnaires handed out to 308 dietitians worked in institutional foodservice operation including elementary, middle and high schools, hospitals, business and industries. In terms of TQM importance and performance, the more important dietitians perceived, the higher their performance level rose. Data form the IPA, external and internal customer satisfaction, executive ability, communication system and technology, information technology and application ability, food process, strategy, and leadership were required further improvement by dietitians. Of present organizational culture model, human relations model and open systems model were more likely to be adopted by dietitians in middle and high schools. According to the type of foodservice management, the open systems model was more preferred by dietitians from self-operated operations rather than respondents from contracted operations. Canonical correlation analysis between TQM performance and organizational culture showed canonical correlation to be higher (canonical correlations coefficient: .66). In conclusion, TQM performance-organizational culture showed higher canonical correlation. In the organizational culture, foodservice operation is capable of improving the aims for the rational goal model and the open systems model. The results showed that TQM performance and organizational culture had significant relationship, especially positive organizational culture emphasizing on internal process and rational goal model would have influence on TQM performance of dietitians. Foodservice operation, however, should recognize importance of open and development culture to improve dietitians' TQM performance. To apply open system foodservice organization should encourage dietitian and foodservice employees to challenge and compete for the works, Moreover, organizational effort such as information exchange program and support system should be established.

It is difficult to find an appropriate ordering policy for a many types of items. One of the reasons for this difficulty is that each item has a different demand trend. We will classify items by shipment trend and then decide the ordering policy for each item category. In this study, we indicate that categorizing items from their statistical characteristics leads to an ordering policy suitable for that category. We analyze the ordering policy and shipment trend and propose a new method for selecting the ordering policy which is based on finding the strongest relation between the classification of the items and the ordering policy. In our numerical experiment, from actual shipment data of about 5,000 items over the past year, we calculated many statistics that represent the trend of each item. Next, we applied the canonical correlation analysis between the evaluations of ordering policies and the various statistics. Furthermore, we applied the cluster analysis on the statistics concerning the performance of ordering policies. Finally, we separate items into several categories and show that the appropriate ordering policies are different for each category.

Purpose: The purpose of this longitudinal study was to examine the relationship between postpartum care performance and postpartum health status. Sample: The study subjects were 82 mothers who delivered full-term infants at 3 hospitals at P city. Data were collected for their health status at the postpartum unit and the sample was followed up to 6 weeks postpartum to collect postpartum care performance and health status. Results: Mothers rated postpartum care performance as moderate to high and especially rated the maternal role attainment the highest. Mothers experienced 4 physical symptoms and moderate levels of fatigue. In addition, they experienced moderate levels of positive affect and low levels of negative affect at both times. Canonical correlation revealed that ostpartum care performance was related to postpartum health status with 2 significant canonical variables. The first variate indicated that mothers who performed hospitality, physical and emotional recovery, self-caring, and role attainment well showed higher positive affects, lower negative affects, fewer physical symptoms, and lower levels of fatigue. The second variate showed that the greater the performance of caring and physical and emotional recovery, the fewer physical symptoms and lower levels of fatigue. Conclusion: Although Korean traditional postpartum care performance was related to postpartum health status, the further study is needed to identify the causal relationship between them. Nurses need to integrate the perspective of westernized postpartum care and Korean traditional views of postpartum approach to maintain and promote women's health.

Face recognition has received a great deal of attention for the wide range of applications in real-world scenario. In this scenario, mismatches (so called heterogeneity) in terms of resolution and illumination between gallery and test face images are inevitable due to the different capturing conditions. In order to deal with the mismatch problem, we propose a local feature learning method using deep canonical correlation analysis (DCCA) for heterogeneous face recognition. By the DCCA, we can effectively reduce the mismatch between the gallery and the test face images. Furthermore, the proposed local feature learned by the DCCA is able to enhance the discriminative power by using facial local structure information. Through the experiments on two different scenarios (i.e., matching near-infrared to visible face images and matching low-resolution to high-resolution face images), we could validate the effectiveness of the proposed method in terms of recognition accuracy using publicly available databases.
