Clinical practice in nursing education provides an opportunity for students, through the process of ap-plying theoretical knowledge to practice, and to learn nursing skills as well as being socialized into nursing and as such decrease the reality shock of actual nursing practice. Because of a shortage of nursing faculty, the job of achieving the objectives of the clinical practice had been turned over to the head nurses. This resulted in many problems, such as, unclear location of responsibilities and inadequate feedback from head nurses. Therefore this study was done to introduce and evaluate the use of preceptors as a way to minimize the above problems, and to maximize the achievement of the clinical practice objectives. Using an adaptation of Zerbe's (1991) three-tiered team model, clinical practice was done using a preceptor, a head nurse and a clinical instructor, each with different and well defined roles. The subjects of this study were 67 senior students of the College of Nursing of Y University in Seoul whose clinical practice in adult nursing was carried out between May 1, 1994 and December 8, 1994. There were 22 preceptors who had at least two years of clinical experience and who were recommended by their head nurses. They were given additional education on the philosophy and objectives of the College of Nursing, on communication skills, on the theory and practice of education, and on nursing diagnosis and education evaluation. The role of the preceptor was to work one-to-one with students in their practice. The role of the head nurse was to supervise and evaluate the preceptors. The role of the clinical instructor was to provide the education program for the preceptors, to provide ad-vice and suggestions to the preceptors and to maintain lines of communication with the college. With each of these roles in place, it was thought that the effectiveness and efficiency of the clinical practice could be increased significantly. To evaluate the effectiveness of the preceptorship, the three - tiered model, Lowery's Teacher Evaluation Opinion Form translated and adapted to Korea was used to measure student statisfaction. The Clinical Practice Compentency Evaluation Tool developed by Lee et ai was also used to measure student competencies. The results of this study are as follows 1. The satisfaction with clinical practice was higher with the introduction of the perceptors than it was before they were used. (t=-5.96, p=<.005) 2. The clinical practice competencies were higher with the introduction of the preceptors than it was before they were used(t=-5.l3, p<.005) 3. In order to analyze areas not measured by the quantitative tools additional analysis of the open questions was done. The results of this analysis showed that : 1) The students felt positive about their sense of security, confidence, handling of responsbility, and being systematic. They also felt positive about improvements in knowledge, opportunities for direct care, and socialization. 2) The students felt negative about the technical part of their role, lack of knowledge by the preceptor, unprofessional attitudes on the part of the preceptor, difficulty in the role of the professional nurse(student). 3) The preceptors felt positive about their responsibility, motivation, and relationship with the college. 4) The preceptors felt negative about their bur-den. Introduction of the preceptorship model will lead to change and improvement in the negative factors discussed above, solve problems in the present clinical education system, increase continuity in the education of the students, help with socialization of the students and motivation of the preceptors to up-grade their education and increase their confidence. These objectives must be obtained to further the development of professional nursing, and thus, making the preceptorship a reality is our job for the future.

The purpose of this study was to know the conscious of eating habit of housewife. The data were collected from 250 housewives who were the age group of 20-60's in Sang-Ju. The survey was taken place from May to June in 2000. The result showed that there were significant differences in eating habit's consciousness according to housewife's age group: 1. As the age goes up, the housewife had less consideration herself when they purchased food and decided cooking method. 2. As the age goes down, the order in having meal was depended on conditions. But as the age goes up, they considered the order as important thing like followings; eating together, eating separately according to the sex, male first, senior first, housewives lastly. 3. The survey showed that there was distinction depending on sex in meal as age goes up. And The subject was conscious that the delicious and valuable meal served to male, senior and child before. 4. Regardless of senior, the consciousness for the skipping meal was high as the age goes down. 5. As the age goes up, female and seniors showed that leftover was not so good. 6. The consciousness that housewives were responsible for preparing the meal was high as the age goes up, but they had further difficulty in preparing meal as the age goes down. 7. In considering that male and senior should be participated in the kitchen work, they had high consciousness as the age goes down. 8. About role of cooking, the consciousness was hish in case of male as the age goes down, in case of female and housewife were high as the age goes up. 9. As the age goes up, The consciousness was high that Female must buy the food. 10. As the age goes up, they had high consciousness in considering that the meaning of meal was related to survival, that noodle and bread were not meal. And the consciousness about that eating out was not good for health was high as the age goes up.

Nitrogen compounds of Panax ginseng and their biological activities in plant and animal were reviewed. Major nitrogen compounds found in P. ginseng are free amino acids. Water solilble proteins, indouble proteins and peptides. Minor nitrogen compounds are dencichine. Glycolyroteins, amines, alkaloides, methoxy or alkyl pyrazine derivatives, free nucleosides and nucleic acid bases. 4-methyl-i-thiazoltethanol and pyroglutamic acid the contents of total nitrogen and protein in root Increased until 13 years old which was the highest age tinder investigation. Soluble protein content increased with the root weight and was higher in xylem pith than cortex-epidermis indicating the close relation with root growth. Arginine, which covered 58% of total free amino acids, may serve as storage nitrogen. Arginine seems to be changed into proline in rhizome. threonine in stem and again threonine and arginine in leaf. The greater the root weight the higher the polyamine stimulated Polyamine stimlllated the growth of root callus. Physiological roles of other minor nitrogen compounds are unknown although content is relatively high ((1.if) 6.w). Biochemical and pharmacological activities of some nitrogen compounds for animal were more investigated than physiological role there plant itself. Radiation and U.V protective function (heat stable protein). insulin-like activity in lipogenesis and livolysis (adenosine and pyroglutamic acid), depression of blood sugar content (glycopevtide). htmostatic and nellrotoxic activity (dencichine) and, sedative and hypnotic activity (4-methyl-i-thiazoleethanol) are reported. Heat stable protein increased with root age. The traditional quality criteria appear to be well in accordance with biological activities of nitrogen compounds. Chemical studies of nitrogen compounds seem relatively rare, probably due to difficulty of isolation, subsequently the investigations of biological activities are little.

According to the trend of a large-sized vessel and a industrial carrier, the role of the independent contractors such as transport terminal operators, stevedores and warehousemen is increasing the base of cargo distribution that include the function of storage, warehousing, loading, unloading, trimming, dunnaging and lashing. But the common law doctrine of privity of contract has been a perennial source of difficulty for litigants seeking to enforce rights and obligations arising under a bill of lading contract. When carriage contract is negotiated, the concerned parties will be aware that some portion of obligations arising from the contract will be performed by the independent contractors engaged to carry out a particular function. It is reasonable for the independent contractors to be allowed the benefit of the carrier under the contract of carriage. As a part of the alleviating measures for the liability of independent contractors has been allowed various schemes, specially including 'Himalaya Clause'. Therefore, this study performed the validity of 'Himalaya Clause' by means of a recent judicial precedent by the Supreme Court and analyzed the rights of third parties, specially transport terminal operators, under the contract of carriage.

Individuals with autistic spectrum disorders (ASD) have difficulty inferring other people's feelings from their facial expressions and/or from situational cues, and therefore, they are less able to respond with prosocial behavior. We developed a computer-based training program to help teach the connection between facial-based or situation-based emotions and prosocial behavioral responses. An 8-year-old male school child with ASD participated in the study. In this program, he was trained to identify persons in need of help and appropriate prosocial responses using novel photo-based scenarios. When he misidentified emotions from photographs of another's face, the program highlighted those parts of the face which effectively communicate emotion. To increase the likelihood that he would learn a generalized repertoire of emotional understanding, multiple examples of emotional expressions and situations were provided. When he misidentified persons expressing a need for help, or failed to identify appropriate helping behaviors, role playing was used to help him appreciate the state of mind of a person in need of help. The results of the training indicated increases in prosocial behaviors during a laboratory task that required collaborative work. His homeroom teacher, using a behavioral rating scale, reported that he now understood another's emotion or situation better than before training. These findings indicate the effects of the training are not limited to the artificial experiment situation, but also carried over to his school life.

The tumour suppressor genes, p53 and pRb, are known to play important roles in neoplastic transformation. While molecular routes to the uncontrolled growth of hepatocytes, leading to primary liver cancer have generated considerable interest, the roles of p53 and pRb mutations in hepatocellular carcinoma (HCC) and hepatoblastoma (HB) remain to be clarified. We examined the immunohistochemical expression of p53 and pRb gene products in 26 HCC and 9 HB, sampled into tissue microarray blocks. 10 (38%) of 26 HCC showed > 10% tumour nuclear staining for p53 protein, 3 of these also being HbsAg positive. Conversely, none of 9 HB expressed nuclear p53 immunopositivity. Some 24 (92%) HCC and 8 (89%) HB showed loss of pRb nuclear expression. Two of the 26 HCC and one of the 9 HB showed >10% tumour nuclear staining for pRb protein. Our results suggest that p53 does not have an important role in the development of HB but may contribute in HCC. There is also loss of pRb expression in the majority of HCC and HB, supporting loss of pRb gene function in the hepatocarcinogenesis pathway. However, a comparison of the staining profiles of p53 and pRb proteins in HCC and HB did not reveal a consistent pattern to differentiate between the two types of tumours immunohistochemically. Hence the use of p53 and pRB protein expression has no contribution in the situation where there is a diagnostic difficulty in deciding between HCC and HB.

Alternative hosts increase the difficulty of disease management in crops because these alternate hosts provide additional sources of primary inoculum or refuges for diversity in the pathogen gene pool. Agropyron cristatum (crested wheatgrass), Bromus inermis (smooth bromegrass), Pascopyrum smithii (western wheatgrass), Stipa viridula (green needlegrass), and Thinopyrum intermedium (intermediate wheatgrass), commonly identified in range, prairie, verge, and soil reclamation habitats, serve as additional hosts for Pyrenophora tritici-repentis, the cause of tan spot in wheat (Triticum aestivum L.). A. cristatum (five lines), B. inermis (seven lines), P. smithii (four lines), S. viridula (two lines), and T. intermedium (six lines) were tested for their reactions to 30 representative P. tritici-repentis isolates from races 1-5. Plants were grown until the two-three-leaf stage in a greenhouse, inoculated individually with the 30 isolates, held at high humidity for 24 h, and rated after 7 days. All lines developed lesion types 1-2 (resistant) based on a 1-5 rating scale. Also, leaves from an additional plant set were infiltrated with two host selective toxins, Ptr ToxA as a pure preparation and Ptr ToxB as a dilute crude culture filtrate. All lines were insensitive to the toxins. Results indicate that these grass hosts have a limited or nonsignificant role in tan spot epidemiology on wheat in the northern Great Plains. Additionally, the resistant reactions demonstrated by the grass species in this research indicate the presence of resistance genes that can be valuable to wheat breeding programs for improving wheat resistance to P. tritici-repentis.

This paper has surveyed above all what the patients call for physically, psychologically, and socially and researched how the ministers have acknowledge on cancers, their patients and hospice by means of enquete. To the difficulty the pastors should give their hands. This study researched what thoughts and behaviors the ministers actually had by the method of questionnaire. It was done from October 20, 1997 through December 10, 1997 on seven thousand of questionnaire paper of which 149 given back on the line of post or firsthandly were analyzed. The questioness consisted of 141 men(94.6%), 8 women(5.4) and 104 pastor on appentice(69.8%). There were 58 questionees(38.9%) who were hospitalized of their own diseases, and 121 questionees(81.3%) who had cancer patients hospitalized among their church people, relatives, or friends. Most of all the questionees(79.9%) had not any experience, such as they took some instruction about cancer patients. 72.5% of all the questionees had not ever served patients around them. The followings are the contents of the enquete: the questionees' view to chronic patients and death, where they put the priority in the case of that they look after patients who are under terrible pain ahead of death, what they think of such a situation as a patient has no technical possibility to be recuperated, why they think pastors do not like to visit chronics, which therapy they choose, whether they mainly control their pain or they do their best in order to heal their diseases, how much the questioned ministers know hospice, where and how they get the information on it, how much important role they play in the hospice team, whether the volunteers for hospice have not worked on account of pastors' misunderstanding to hospice service, whether the ministers want to take part in hospice service with their church people or not, and so forth. Suggestion: First, the education and P.R. about hospice are requested for the ministers. Second, the ministers must participate in hospice activities actively. Therefore the ministers and the churches must firsthandly take part in hospice activities beyond the education only and the raising of the recognition to them.

English stress plays such a critical role in understanding spoken English words that its misplacement can lead to a breakdown of communication. Korean learners of English, whose native language is known to lack this feature, are expected to have some difficulty acquiring this English prosodic system. This study explored how Korean is different from English in manifesting prominence at the word level and how the interlanguage of Korean learners of English is dissimilar to both languages in that regard. Four polysyllabic English loanwords in Korean and their English source words were used as stimuli. Ten native English speakers read the English source words while ten Korean learners of English read the English loan words first and then the English source words. The analysis of 120 speech samples revealed that Korean words did not have any salient syllable realized by all stress features: duration, amplitude, and F0. On the contrary, English words had syllables with relative prominence, which was consistently manifested by all the features. Interestingly, in realizing English stress, the interlanguage of the Korean English learners bore more resemblance to that of English than that of their native language.

The binding of TATA-binding protein (TBP) to the TATA-box containing promoter region is aided by many other transcriptional factors including TFIIA and TFIIB. The mechanistic insight into the assembly of RNA polymerase II preinitation complex (PIC) has been gained by either directly altering a function of target protein or perturbing molecular interactions using drugs, RNAi, or aptamers. Aptamers have been found particularly useful for studying a role of a subset of PIC on transcription for their ability to inhibit specific molecular interactions. One major hurdle to the wide use of aptamers as specific inhibitors arises from the difficulty with traditional assays to validate and determine specificity, affinity, and binding epitopes for aptamers against targets. Here, using a technique called the bio-layer interferometry (BLI) designed for a label-free, real-time, and multiplexed detection of molecular interactions, we studied the assembly of a subset of PIC, TBP binding to TATA DNA, and two distinct classes of aptamers against TPB in regard to their ability to inhibit TBP binding to TFIIA or TATA DNA. Using BLI, we measured not only equilibrium binding constants ($K_D$), which were overall in close agreement with those obtained by electrophoretic mobility shift assay, but also kinetic constants of binding ($k_{on}$ and $k_{off}$), differentiating aptamers of comparable KDs by their difference in binding kinetics. The assay developed in this study can readily be adopted for high throughput validation of candidate aptamers for specificity, affinity, and epitopes, providing both equilibrium and kinetic information for aptamer interaction with targets.
