Objectives : The new health technology assessment (nHTA) involves evaluating the safety and efficacy of the new health technology under the Medical Services Act by the New Health Technology Assessment Project Division from 2007. The purpose of this study is to understand the status of applications and recent trends of the results, and suggest strategies for the development of new health technologies in Korean Medicine. Methods : We investigated and analyzed the results of evaluation of new health technology of whole conventional medical and the list of new health technologies in Korean Medicine provided by the New Health Technology Assessment Project Division from 2007 to 2016. Results : The number of applications for new health technology of Korean medicine was low as 41 items in the whole number of 2,013 items. The evaluation method of new health technologies in both, the whole medical and Korean medicine fields was the same, but the tendency in results was very different. Most of the new health technology items in Korean medicine were classified as existing technology (20 items), early stage technology (7 items), and Only 2 items were evaluated as research stage technology. Conclusions : In order to develop new health technology in the Korean medical field, we have made suggestions about the health technology assessment systems, R&D infrastructures, and corporation with conventional medicines.

This research is to identify the status of the curriculum based on dental hygiene programs, the awareness about medical service technologists, etc. act and job demands of students in the department of dental hygiene. The data was collected by self-reported questionnaires from 536 dental hygiene students. This data was analyzed using SPSS 19.0K program for Windows with a statistical significance level of 0.05. The level of objective awareness of the current Medical Service Technologists Act was higher for females(9.14±1.11) than for males(8.56±1.79)(p=0.043). Meanwhile, there was little difference between college and university(p=0.639), whereas the level dropped as the number of clinical practice experiences went up(p=0.045). Therefore, the law in convergence needs to be revised to reflect the reality of dental hygienists' work, and the dental community needs to change its perception that dental hygienists are not only recognized as assistant workers but also as business partners.

Objective: There is increasing evidence for the expression of rat in gene in several extrapituitary sites including testis and ovary. We also have demonstrated that the local LH expression in the rat epididymis and uterus, the major accessory sex organs in male and female reproductive system, respectively. Design: The present study was undertaken to elucidate whether the gene for LH receptor is expressed in rat uterus and whether the expressions of uterine LH and its receptor are differentially regulated during estrous cycle. Presence of the transcripts for rat LH receptor in the rat uterine tissue were confirmed by touchdown reverse transcription-polymerase chain reaction (RT-PCR). Results: In $LH{\beta}$ semi-quantitative RT-PCR, the highest expression level was shown in estrus stage. The level of ill receptor transcripts was also fluctuated during estrous cycle. In ovariectomized rats (OVX + Oil), the expressions of both uterine LH and LH-R were markedly reduced when compared to those from normal rats. Supplement with estradiol $17{\beta}$ to the ovariectomized rats (OVX + $E_2$) restored the expression levels of LH and its receptor to the levels in uteri from normal rats. Conclusion: Our findings indicated that 1) LH and its receptor gene are expressed in the rat uterus from cycling rats, 2) the expression of uterine LH and its receptor is mainly, if not all, under the control of ovarian sex steroid(s). These results suggested that the uterine LH may act as a local regulator with auto and/or paracrine manner, though the posibility that the pituitary LH may act directly on the regulation of uterine functions could not be discarded.

A 6-month-old intact female Bichon Frise dog weighing 0.9 kg presented with vomiting, anorexia, and lethargy persisting for 3 days. No remarkable abnormalities were detected on the history or physical examination. Laboratory findings were mostly normal, except for elevated levels of alkaline phosphatase (ALP) and blood urea nitrogen (BUN). Abdominal radiography revealed a fluid-dilated stomach and gas-dilated intestinal loops in the regional areas. Abdominal ultrasonography was performed to investigate the cause of gastrointestinal dilation, which revealed a rectangular, homogeneous, echogenic foreign material with no shadowing in the small intestine, causing mechanical obstruction. Upon further inquiry involving detailed re-take of history with the owner, a history of ingesting dog gum 4 days prior was identified. On surgical enterotomy, the hard pet food was identified and removed from the distal duodenum. Postoperatively, the patient's clinical signs showed complete improvement, with a return to normal appetite. The present case demonstrates that less-digestible, hard pet food, despite showing no shadowing on ultrasonography, can act as a foreign material, causing mechanical intestinal obstruction in a small-breed puppy. Furthermore, surgical removal of these materials is necessary in cases of intestinal obstruction.

Objectives : ShangHanLun is a clinical guideline, and its core is in the part of Six-meridian Diseases. In recent philological sutdies, independent textual analysis of Shanghanlun is essential to define the scope of research. Methods : By the textual study, I defined the Shanghanlun clinic model. And I researched about medical range of Shanghanlun, and relations between Shanghanlun and JinGuiYaoLue, and between Shanghanlun and Huangdineijing. Results : In six topic sentences, the word '-之爲' means 'a process'. In provisions following topic sentences, the word '者' means 'a person'. So Shanghanlun is describing processing factors of Six-meridian Diseases and related human changes with clinical therapy. In the philological studies, meaning of '傷寒' was possibly just the 3rd provision of the greater yang disease part. Practically Shanghanlun's study range is over the concept of Cold damage today. Additionally Jinguiyaolue deals diseases, but Shanghanlun deals human. Gangpyeong-Shanghanlun's phrases can be separated into five part, and oldest part is independent of Huangdineijing. Conclusions : So we need to set a new and independent clinic model of Shanghanlun to verify it. The Shanghanlun's clinic model has a 3 steps. 1st step is to find 6 type defined symptoms, which act as processing factors of Six-meridian Diseases. 2nd step is to confirm a human changes after a Disease appeared. 3rd step is to treat a patient as a provision suggests. Philologically Shanghanlun's clinic range is not limited by the word '傷寒'. And many concepts in Shanghanlun should be independent of Huangdineijing.

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.

Objective : Because the cause and etiology of chronic headache is not yet fully explained, the treatment of this symptom is not simple. This study compares the effects of aroma acupuncture and normal acupuncture applied on chronic headache patients, in order to establish a primary data for further studies of new treatments and developments of new practical acupunctures. Methods : 38 clinical experiment participants were gathered and through a questionnaire patients who experienced headache for more than 4 hours a day and more than 15 days per month were qualified as Chronic Headache patients. The qualified patients were classified in to two groups, aroma acupuncture group(Aroma AT group, n=23) and normal acupuncture group(AT group, n=15). Treatment was applied 2 times a weeks for 8 weeks. The acupoints, GV20, HN23, ST8, HN46, TE17, GB20, LI20, LI11, LI14, ST36, and LR3 were stimulated for 20 minutes in both the groups. The effects of both groups were analyzed using VAS scores and BPI (Brief Pain Inventory). Results : The VAS pain scores improved significantly in both groups. The decrease rate was larger in the Aroma AT group(p<0.05). The BPI scores for the both groups also decreased. The improvement in the Aroma AT group was larger(p<0.05). Conclusion : Aroma acupuncture applied on chronic headache patients showed effects of relieving pain, improving general activities, changing the mood, and improving sleeping behaviors. These effects were analyzed using VAS scores and BPI. The Aroma AT group showed significant changes of VAS and BPI compared to the AT group, suggesting that this new practical acupuncture is very effective when treating chronic headaches. Further researches are needed to evaluate the distinct functional mechanism of aroma acupuncture, but this study is meaningful in the sense that it will act as a fundamental study to build on.

Salmonella remains a primary cause of food poisoning worldwide, and massive outbreaks have been witnessed in recent years. Therefore, this study investigated the antimicrobial activity of methyl gallate (MG), which exhibited good antibacterial activity ($MIC=3.9-125{\mu}g/ml$) against all the bacterial strains tested. In a checkerboard dilution test, MG markedly lowered the MICs of ciprofloxacin (CPFX) against Salmonella. The combined activity of CPFX and MG against Salmonella resulted in fractional inhibitory concentrations (FICs) ranging from 0.0037 to 0.015 and from 0.24 to $7.8{\mu}g/ml$, respectively. Meanwhile, the FIC index ranged from 0.31-0.37, indicating a marked synergistic relationship between CPFX and MG against Salmonella. Time-kill assays also showed a decrease in the CFU/ml between the combination and the more active compound. Therefore, this study demonstrated that MG and CPFX can act synergistically in inhibiting Salmonella in vitro.

The effects of the an immunosuppressive drug cyclosporine A (CsA), on the salivary gland are largely unknown, even though clinical trials for the stimulation of salivation using CsA have been attempted. Cyclophilin A (CypA) is known to be a binding protein for CsA. CypA has cell proliferation and tissue matrix change activities. In our present study, the presence of CypA in the gland and effects of CsA on CypA expression were investigated by immunohistochemistry, immunoblotting and RT-PCR analyses. CypA was immunohistochemically detected in various kinds of ducts in the submandibular glands of Sprague Dawley rats. The CypA mRNA level was highest at postnatal day 1 and gradually decreased in a time-dependent manner up to adulthood. The expression of CypA increased after a 10 day subcutaneous administration of CsA in postnatal day 1 rats. Surgical sections of the chorda-lingual nerve with impaired salivation showed no changes in CypA expression. A cell proliferation assay using PCNA anti-serum showed increased cell division following CsA treatment. These results suggest that CsA and CypA may act on ductal cells to regulate saliva composition rather than salivation levels.

With the 2-Butanethiol, which is an unidentified inhalation toxic material, acute inhalation toxicity was tested with SD rats. The $LC_{50}$ was evaluated to be 2,500 ppm (9.22 mg/L) or higher which falls under the criteria of acute toxicity Category 3 (500<$LC_{50}$<2,500 ppm) in the Industrial Safety and Health Act. In the subchronical inhalation toxicity test by 0, 25, 100, and 400 ppm, 6 hours a day, 5 days a week, for 13 weeks repeated exposure, though no death or particular clinical presentation was observed, in the female 25 and 400 ppm group, including weight change, and in each concentration group including 400 ppm, change of feed rate, eye stimulation, motility change in male group, and lesions in blood and blood biochemical were observed. In the internal organs weight, 25, 100, and 400 ppm groups in male and 400 ppm group in female showed significant (p<0.05) changes in kidney, liver, thymus, and lung. In the pathological tissue test, severe cortical tubular hyaline droplets were observed in the male 400 ppm group, and all male rats of 400 ppm group and 2 female individuals showed tubular degeneration/regeneration accompanied with pigmentation, showing that the target organs of inhalation exposure of 2-Butanethiol are spleen, kidney, nasal cavity, and adrenal. Through the tests, the NOEL of 2-Butanethiol was evaluated to be 25 ppm (0.092 mg/L) or less for both male and female.
