Objectives : The Primo system is a hypothesis on the new circulation system. It orginates from Bonghan theory. Bonghan theory is about the anatomical substance of acupuncture point and meridian system. It has been regarded as a misunderstanding of the lymphatic system or as a made-up story for the past 40 years. Since 2002, many studies have been published either to support the theory or to refute the old viewpoint. But there are still difficulties about the proper sampling. The purpose of this study is to find out the discriminative criteria of Organ Surface Primo sytem by reviewing the Kim Bonghan's publications. Methods : Abstract of description about the Organ Surface Primo system in 5 publications of Kim Bonghan are weighted by the reverse order of publication. Results and Conclusions : 6 characters of anatomical structure and 11 characters of histological structure are founded as repeated descriptions. We hope that this summarized characteristics would be a good guide to Primo system experiments.

The object of International License Contract is technology. Technology is means to produce visible goods, which are human's intellectual creations such as Intellectual Property Right - patent, design, trademark- and Know-how. Unlike visible goods which decrease as being used, these technologies are possible to be produced expansively and develop additionally. Therefore, the way to make a contract of goods is a sales contract which transfers ownership while technology follows license contract which gives approval of use for a certain period. International license contract means that licensor has right to possess, allows licensee to use licensed technology for a fixed period and takes royalty. So there are various matters such as selection of the duration of a contract, confirmation of technology range, competition limitation, technique guidance and support, calculation of royalty, withholding tax between parties. This study examines licensor's grant of license and competition limitation. Intellectual property rights fundamentally give exclusive rights to the creator so the licensor use or dispose of his or her intellectual property rights at will. Technology transfer is possible through license contract because of this right. But licensor must exercise his or her intellectual property rights within a reasonable limit. It means, when licensor makes an unreasonable demand abusing his or her position, it is regarded as competition limitation clause and the deal itself may become null. Therefore, restraint on competition needs to be examined in detail as it influences on contract validity. Each country has their own competition laws for establishing a fair market order and inspection guide and guideline for judging whether there is any unfair act related to intellectual property rights. Judgment on intellectual property rights is subject the technology-introduced country's domestic laws and thus, contracting parties each need to precede opposite nation's domestic laws system.

Background: The purpose of this study is to investigate the effects of administration order when a sedative drug (midazolam) and an opioid analgesic drug (fentanyl) is applied for moderate intravenous (IV) sedation in dentistry. Methods: A retrospective chart review was conducted in one dental clinic during its transition from a midazolam-first to a fentanyl-first protocol for dental procedures requiring moderate IV sedation. Physiological parameters, drug administration times, patient recovery times, drug dosages, and patient recall and satisfaction were investigated for differences. Results: A total of 76 charts (40 midazolam-first and 36 fentanyl-first administrations), were used in the analysis. Administering midazolam first resulted in an average 4.38 min (52%) decrease in administration times (P < 0.001), and a decrease in procedural recollection immediately following the procedure (P = 0.03), and 24 to 48 hours later (P = 0.009). Administering fentanyl first required an average of 2.43 mg (29%) less midazolam (P < 0.001). No significant differences were found for change in vital signs, minimum oxygen saturation levels, recovery times, and patient satisfaction (P > 0.05). Oxygen saturation levels did not drop below 90% for either group; however, 5 cases in the fentanyl-first group fell to between 90% and 92%, compared with 0 cases in the midazolam-first group. Conclusions: The administration order of fentanyl and midazolam may have different effects on patients and the sedation procedure. Findings from this study should be used to facilitate discussion among dental practitioners and to guide additional research investigating this topic.

Distraction osteogenesis is a well-established clinical treatment for limb length discrepancy and skeletal deformities. Appropriate mechanical tension-stress is believed not to break the callus but rather to stimulate osteogenesis. In contrast to fracture healing, the mode of bone formation in distraction osteogenesis is primarily intramembranous ossification. Although the biomechanical, histological, and ultrastructural changes associated with distraction osteogenesis have been widely described, the basic biology of the process is still not well known. Moreover, the molecular mechanisms in distraction osteogenesis remain largely unclear. Recent studies have implicated the growth factor cascade is likely to play an important role in distraction. And current reserch suggested that mechanical tension-stress modulates cell shape and phenotype, and stimulates the expression of the mRNA for bone matrix proteins. This article presents the hypotheses and current research that have furthered knowledge of the molecular biology that govern distraction osteogenesis. The gene regulation of growth factors and extracellular matrix proteins during distraction osteogenesis are discussed in this article. It is believed that understanding the biomolecular mechanisms that mediate distraction osteogenesis may guide the development of targeted strategies designed to improve distraction osteogenesis and accelerate bone healing.

Objectives: The aim of this study is to determine the incidence, location, and orientation of maxillary sinus septa in formalin embalmed cadavers. Materials and Methods: The study was conducted on 210 cadaveric heads available in our department. After taking the mid-sagittal section the specimens were opened from the medial aspect and the sinus sinus septa, their anatomical plane, location and dimensions. Results: The mean linear distance between maxillary sinus floor and its anatomical ostium was $26.76{\pm}5.21mm$ and $26.91{\pm}4.96mm$ on right and left side, respectively. A total of 59 maxillary sinus septa (28.1%) were observed in 210 maxillary specimens. Septae were most common, 33 septa (55.9%), in the middle region (between first and second molar tooth) of the sinus cavity. The maxillary sinus membrane (Schneiderian membrane) adhered tightly to the maxillary sinus and over the septae. Significantly more maxillary sinus septa were observed in edentulous maxillae in comparison to the dentate upper jaw. Conclusion: Knowledge of location of maxillary sinus ostium is mandatory for the rhinologist for drainage of secretions in maxillary sinusitis. The morphological details of maxillary sinus septa, particularly their location and anatomical planes, will guide dentists in performance of safe implant surgeries. The maxillary antrum septa of category I and II may complicate the procedure of inversion of bone plate and elevation of sinus membrane during maxillary augmentation surgeries. The category III septa observed in the sagittal plane were embedded by one of the branches of the infraorbital nerve in it, and if accidentally cut will lead to infraorbital nerve palsy in maxillary sinus surgeries.

We would like to suggest the guideline of use of materials of sexual education for adolescent in school by examining the status of use of materials and by evaluating the video materials frequently used. Survey was done by enquetes on status of use of materials of sexual education from school nurses in 190 primary, 44 middle and 50 high schools in Seoul, Kyonggi-do and Kangwon-do from August 1999 to February 2000. The frequently used 84 videotapes were evaluated on their contents. As for the status of use, 99.3% of subjected schools possessed the materials for sexual education. Decision of purchase was determined according to the review of contents (92.6%). Information about materials was received by the advertisement in newspapers or broadcasting (46.1%) or recommendation of peer teacher (32.4%). Videotape was most frequently used (64.1%) rather than books or CD. Teachers concerns on the materials were the educational content according to developmental stage of students (41.9%), content provoking interest (33.5%) and concrete guide for teacher (10.6%). As for the evaluation of the contents of videotapes, a subject of education was not described out of 46.6%. Videotape producer were mostly the Government-affiliated institutes or non-profit organizations (86.8%). The year of production was indicated from 41.7%. Running time range of 21-30 minutes was highest (55.9%). The price was marked in only one videotape. Subjects of contents were general sexual education (34.5%), sexual violence or sexual harassment (21.4%), pregnancy and contraception (14.2%) and AIDS and sexually transmitted diseases (8.3%) and dating and adolescent change (4. 8%), and etc (11.9 %). According to above results, we suggested that materials for sexual education should be completed with a description on the subjected group, summary of content, information on the tape producer, year of production, running time and sale price.

Recently, due to external environment like the changes in health policy and various healthcare accreditations, along with hospital's internal efforts to improve the quality of medical services, demands for the development of medical information systems are increasing. Some examples are clinical information like DUR (Drug Utilization Review), CVR (Critical Value Report), and automatic benefit processing by treatment purposes, or hospital DSS (Decision Support System) on overall medical practice. Such systems act as a guide in making clinic judgments during practice or in other medical practice, and their effects on the medical treatment improvements are being proven by previous studies. In the reality of increasing attention in the effects of medical treatment improvement, studies related to hospital DDS were mostly focused on clinical, technical, and engineering points of view, and studies focusing on the user viewpoint are very limited. In order to verify the effects of DSS on practice improvements and hospital's management performance, this study used a research model constructed to verify how SERVQUAL of hospital DSS affects hospital management performance in BSC (Balanced Score Card) point of view. To empirically verify the research model, a questionnaire was conducted on the basis of "K-University Hospital's DSS" on clinicians and hospital employees related to system development, and the relationships between the factors were analyzed through path analysis. As a result of path analysis, excluding reactivity, tangibility, confidence, reliability, empathy among service qualities, had partially significant effects on management performance factors (learning and growth, internal process, financial affairs). This study is to prepare the theoretical ground on the management performance analysis of hospital DSS, and suggest the service quality of the system that should be considered in the planning and development stages for improved system.

Purpose: The aim of this study was to develop the nursing management core task and competency matrix for hospital unit managers. The perceived level of importance and performance of identified core competencies by unit managers were also investigated. Methods: Literature review and expert survey identified nursing management core task and competencies. Subsequently, the core task and competency matrix was developed and validated by expert panel. A survey of 196 nurse managers from 3 cities identified perceived importance and performance of core competiences. Results: Thirty-eight nursing management core task and thirty-seven nursing management core competencies were identified comprising five categories; Clinical practice knowledge, Evidence-based practice, Employee development, Strategic planning and Initiative. Based on the core task and competencies, the task and competency matrix for unit managers was developed. In the analysis of importance and performance of core competencies, the mean score of importance ($3.50{\pm}0.30$) was higher than the mean score of performance ($3.03{\pm}0.34$). Conclusion: The development of core task and competencies for unit managers in hospitals provides a guide for the development and evaluation of programs designed to increase competence of unit managers.
