There are many advantages when using IIF and DNA probe methods over anaerobic culture method in that they are time-and effort-saving, more precise and more sensitive. Furthermore, in IIF and DNA probe methods, the detection is possible only with small amount of bacteria, the quantitative analysis is possible, and the cell viability is not necessary. The purpose of this study is to observe the incidence of P.endodontalis by carrying out anaerobic culture, IIF and colony lift using DNA probe method respectively, and to compare these 3 methods in terms of effectiveness and sensitivity in order to identify the most effective detection method. 30 teeth with at least one clinical symptoms, with single canal, and with pulp necrosis were sampled. For sampling bacteria, access cavity was prepared after disinfecting tooth and its surroundings. Then the paper point was inserted up to the periapical area, leave there for a while, and finally it was placed into PRAS Ringer's sol. and PBS sol. In anaerobic culture method, P.endodontalis was identified by biochemical tests after subculturing black and brown colonies which were produced after 7 days of incubation on BAP and Brucella BAP in anaerobic chamber. To identify P.endodontalis in IIF method, species-specific polyclonal rabbit-antisera of P.endodontalis(ATCC 35406) was reacted with sampled PBS sol. dispensed onto glass slide, and then P.endodontalis was examined by phase contrast microscopy after incubating with Goat anti-rabbit lgG conjugated to Fluorescein isothiocyanate. For colony lift using DNA probe method, membranes were laid over colonies on the surface of BAP and were hybridized with cloned DNA probe of P.endodontalis. The existence of P.endodontalis was then identified by the methods of chemiluminescent detection and color metric detection. Black colony was found in 11 teeth out of 30 teeth and P.endodontalis was detected in 6 teeth (20 %) by anaerobic culture method, 16 teeth (53 %) by IIF method, and 7 teeth (23 %) by DNA probe method. IIF method is significantly better in detecting P.endodontalis than DNA probe method and anaerobic culture method. There was no significant differences between DNA probe method and anaerobic culture method. There was significant correlation between the formation of black colony and the existence of P.endodontalis. The probability of detecting P.endodontalis when black colony being present is 2.89 times higher than when not being present. There was significant relationship between the foul odor of clinical symptoms and P.endodontalis. The sensitivity of existing P.endodontalis when foul odor being present was 93.75 %, while the specificity of not existing P.endodontalis when foul odor not being present was 28.57 %. These results suggested that the probes of P.endodontalis will be used to decide the method and prognosis in endodontic treatments.

This study purports to find out the meanings of chemotherapy among cancer patients. The subjects of this study were selected from those patients who have taken chemotherapy at least twice at a hospital affiliated with a university. The twelve subjects agreed to join the present study and had no problem in communication with others. The data were collected through observations and interviews by the researcher. The phenomenological analysis method proposed by Giorgi was adopted for analyzing the data. The experiences of the subjects to chemotherapy were classified into 24 atributes. These attributes were also categorized into four groups such as hope, pain, fear, and ordea according to their meanings. The subjects expressed hope through the attributes such as "the wish for a new life." "the wish for healing." "the plasure form improvement of cancer." "the wish for being discharged form a hospital." "the interest in dietectic treatment." and "the trust in medical staff." Pain was represented by such attributes as "the physical pain", "the suffering from intravenous injection." "the discomfort of hospital environment." and "the economic burden." As for the attributes represention fear, "fear of being hospitalized." "tehr obscurity of uncertain situations." "the fear of side effects." "the fear of recurrence of cancer," "the lack of knowledge of the disease." Finally, nine attributes werw frouped to ordeal "the will endeavouring to recover cancer" "the adaptation to the present situation." "the giving up of being healthy," "the regret of the past life." "the recognition of significant others." "the physical changes." "the emotional changes." "the social changes." "the recollection of illness experiences." The above findings indicate that chemotherapy means hope, pain, fear, and ordeal to those cancer patinests under treatment. Hence, the nursing interventions for those cancer patients need to be directed to maintaining hope, alleviating pain and fear, and overcoming ordeal. There are some suggestions in achieving these goals : (1) the nurses caring for cancer patients need to understand the meaning of chemotherapy experienced by those patients, (2) a nursing specialty of intravenous injection needs to be developed, (3) interventions for providing emotional support should be devised, (4) nursing care should also be available to those cancer patients being dischaged at home.

Reaching up the present from the past, the design was reflected in our life, thereby having brought about great development in the aesthetic harmony or functional part. In the present era, it is advancing in order to seek for the better direction without being satisfied with formativeness. What comes to represent it is UX design, namely, user-experience design. If a user has confusion in using product or environmental facilities, or if a user needs to utilize by analyzing function, this cannot help being inconvenient. Only what a user's behavior is caused by which the cognitive and sensitive attributes interact without inconvenience can be said to be design for a user. Given explaining easily, UX implies to design and develop the designed product or space from the position of a client who uses. Also, it also implies to offer service of being satisfied. For one example, a work can be said that distributes logo to the upper part of web site. That is because of allowing client to be much confused if logo is distributed to the different position. The designed web site in consideration of user's position is developed much now. However, it is the real situation of being still much insufficient in the public facilities that have UX characteristics amid the living environment. There is great interest in UX of the public facilities. However, there are many cases of facing mostly for the first time. The understanding level is thought to be much different. This study examines about a concept of UX design, and about UX design, which considered from the user's position, and analyzes a case. Thus, the aim is to suggest good directivity in designing by efficiently approaching UX that can be difficult theoretically.

A human being as a client has been understood only through a western cultural view so far, now we put forth efforts to set up the concept which is suitable for our korean nursing situation. This paper was reviewed to discover Korean behavior pattern through the concept of the human being in Korean traditional thoughts to keep in pace with above idea and develope the stem of the nursing knowledge. Behavior pattern usually has two aspects, the one is unconscious behavior which conform to old custom and the other is conscious one which abide by a conventional rule. The former was considered through the concept of human being in Tan-kun mythodology, Divination, Tong-hak (Cheondoism) and the latter was Buddism, Confucianism, Sung-ri hak (Human nature and natural Laws), Sil-hak (The rule of Heaven philosophy). Through these traditional thoughts, we can lead Humanity, Present-oriented, Family-focused, Ranking-centered, Fatalism, Projection in Korean behavior pattern and unconscious behavior correspond to the Naturalistic human being, conscious to Societic human being as well. Even though Korean behavior patterns were changed to the times, we found that Korean natural characteristics were remained in the of unconscious-conscious behavior. This point must be considered for caring a client better than anything else in our nursing situiation.

This study was done to examine spiritual well-being of hospice care service volunteers for the purpose of providing them with programs promoting coping skills in response to the wholistic needs of patient effectively, also providing data for professional or nonprofessional hospice training program. Subjects were 123 volunteers serving in 6 hospice centers in Jeonbuk province at present. Data collection were done from 16 Oct. 2000 to 17 Nov. 2000. questionnairs were consisted of activities of hospice care service volunteer and spiritual well-being. The study results were as follows 1.Mean of activities of hospice care service volunteers were 2.433, those activities were divided into 5 categories such as spiritual, activities of volunteer for themselves, psychosocial, physical area and bereavement. The highest mean score was spiritual area 2.578, activities of volunteers for themselves 2.525, psychosocial area 2.456, physical area was 2.359 and the lowest mean score was bereavement area 2.130. 2.Spiritual well-being of hospice care service volunteers was 5.25, the highest mean. In subcategories of spiritual well-being, religious spiritual well-being was higher than existential spiritual well-being, mean score for each one was 5.41, 5.10. 3.Statistically significant relations among demographic characteristics such as gender(t=2.72, P=.008), status of marriage(t=6.067, P=.003), occupation(F=3.795, P=.025), frequency of visiting for volunteered hospice care(F=3.833, P=.024) were noted. 4.Statistically significant demographic characteristics of hospice service volunteers was religion(t=-4.38, p=0.000), status of marriage(F=3.505, p=0.033), frequency of visiting for volunteered hospice care(F=3.107, p=0.048), level of satisfaction from hospice care volunteer service(F=3.610, p=0.030), hospice service volunteers doing more home visiting(5-9times/month) had higher status of spiritual well being than volunteer with less home visiting(1-4times/month) 5.A significant relationship between activities of hospice service volunteers and status of spiritual well-being was noted(r=.236, p=.004), activities of hospice service volunteers was related to both subcategories of spiritual well-being such as religious well-being(r=.210, p=.010) and existential well-being(r=.208, p=.011). From the results of the study It is noted that status of spiritual well-being for hospice volunteers influences on service activities. It means spiritual well-being should be considered as a essential character for hospice service volunteers, it also means that managing and maintaining of status of spiritual well-being for hospice service volunteers is important. On the base of the study recommendation are made as follows: 1.Considering status of spiritual well-being for hospice care service volunteers is needed to promote hospice care activities. 2.It is necessary to develope spiritual well-being programs for hospice care service volunteers and further study for effect validation of them is needed. 3.Further study to sort out effecting variables for hospice care service volunteer activities is needed. 4.It will be desirable to have spiritual well-being information included in the hospice education program.

In industrial fields, human works are being replaced by robots. However, as the use of robots is limited in the process industry where they are operated fixedly, humanoid robots with wide applications need to be developed. Currently a great deal of research is being conducted on humanoid robots with the object of replacing humans in the workplace. However, because of the lack of relevant hardware and difficulty in mechanical parts, only very simple and limited progress is being made. In an effort to overcome these limitations, the purpose of the present study is to develop a kinematical mechanism and a controller. To this end, master arms with 3 degrees-of-freedom for the shoulders and the arms were composed which were able to reproduce human-like motions by simulating the characteristics of joint variables and the trajectory of the end-effector.
