Because of the lack of resources on the importance of cell block, the diagnosis of cytologic specimen has been overlooked. Out of 1,243 cases of non-gynecologic cytology specimen, about 87.1% has been proven to be diagnostically useful. About 0.9% of those were rendered diagnostic by cell block alone. If cell block was not made it could have resulted in misdiagnosis. The effect on making cell block might not be directly linked to the patient but to the pathologist, it can be a helpful secondary tool in lowering the chance of giving false negative results hence. Giving the patient the opportunity of an adequate treatment. This study has proven that cell block has diagnostic value in non-gynecologic cytology. We are doing our best to increase the production rate of cell block and to improve the quality of cytology smears and cell block, so that we can increase the accuracy of diagnosis.

Objectives: This study evaluated clinical trials of acupuncture treatment for hypertension and to assess their methodology and results. Methods: Eight Korean databases and four international databases were searched for clinical trials of acupuncture treatment for hypertension up to June 2011. Study quality was assessed using the risk of bias (ROB) tool. Results: Twenty-four trials of acupuncture for hypertension were included. There were 14 randomized and 1 non-randomized controlled trials and 9 before-after studies. The most frequently used acupuncture points were zsnli (ST36), qch (LI11), fngch (GB20), snynjio (SP06), snjin (LI03) and hgu (LI04). In more than half of the studies, needle retention time was 20~30 minutes. Compared to baseline, change of blood pressure after treatment was significant in all studies. However, the results of effect on blood pressure between acupuncture and control were not consistent. Conclusions: There is insufficient evidence to suggest that acupuncture is an effective treatment for hypertension. Further well-designed clinical trials will be required to evaluate the effects and safety of acupuncture treatment for hypertension.

This study was originated to investigate the imparired parts of the mist and dust blowers and intended to analyze the causes of their failures by the use of the Weibull probability paper. By the use of the paper, the parts which were needed to change the design, the force of the urgency, the mean time between failures of the parts and the basic causes of the troubles could be predicted. The survey showed that the following parts got out of order: (A) flexible rubber hose, (B) blowing fan, (C) lead valve, (D) piston ring. (E) crank main bearing, (F) coil in magneto and (G) needle valve in carburettor. The analysis of the survey indicated that the parts G, C, E and D were belonged to "wear-out failure", and that the mean time between failures became shorter in order as indicated above. To insure longer lives of those parts, it would be necessary to change the design and the material and to upgrade operators mechanical technique of the mist and dust blower. The failure of the parts A, B and F was classified as "randomfailure", and they did not seem to be the "wear-out" at that time. The parts B and F was evaluated as "initial failure". Quality controls and operating tests by the producer. and the operational training for users should be strengthened so as to eliminate these failures. Were the failures only in the parts A, C, D, E, F and G, it could be said that the "reliability" of the mist and dust blower would fall to 10 percent in the second year, and 50 percent of the mist and dust blowers would fail in all parts A, C, D, E, F and G before the blower would have control insect and disease in 58.2 hectares. The use of the Weibull probability paper for analyzing failures of the mist and dust blowers was effective in that it analyzed failure in the relationship between strength of the parts and users actual circumstanoes.

Objectives : Cervical herniated intervertebral disc (HIVD) are common diseases. They can be managed with acupuncture, but the evidence for effectiveness is uncertain. This review analyzed the acupuncture studies of domestic neck pain and cervical HIVD; the purpose of this study was to provide basic data useful for future research. Methods : We investigated acupuncture treatments for neck pain and cervical HIVD by searching 5 Korean Internet databases. The keywords used were "neck pain", "HIVD-cervical spine", and "nuchal pain". A total of 53 research papers (17 case reports, 16 clinical data analyses, 11 randomized controlled trials, and 9 non-randomized controlled trials) were found and analyzed according to the publication year, type of study, treatment, use of filiform needles, and type of pharmacopuncture used acupoint. The effectiveness of acupuncture treatment was determined. Results : 1. Filiform needles have been primarily used in domestic research and were used in at least half of published pharmacopuncture studies. 2. In 51 papers using filiform needles, many studies used only local acupoints; few studies used only distant acupoints. 3. All studies using pharmacopuncture were performed using local acupoints. In particular, the studies based on A-shi point, trigger point, and radiologic lesion sites were useful for multiple purposes. Conclusion : In this study, we analyzed the acupuncture contents of the domestic neck pain and HIVD-cervical spine clinical studies. This study considers the assessment of the quality and efficacy of each study, which is likely to require research that reflects the future.

Objectives : The aim of this study was to describe the details and to assess the clinical evidence of acupuncture and moxibustion for non-specific chronic neck pain. Methods : We searched seven databases including Korean, English, and Chinese databases through July 2016. Studies using acupuncture, moxibustion, pharmacopuncture, electroacupuncture, auricular-acupuncture, acupressure for non-specific chronic neck pain were included. Only controlled clinical trials or randomized clinical trials were assessed. Study design, number of subject, inclusion criteria, intervention, and results were extracted. In addition, details of intervention including needle type, retention time, acupoints were analyzed. Results : Total 64 studies(39 acupuncture, 9 laser, 6 pharmaco-acupuncture, 3 electro-acupuncture, 3 auricular-acupuncture, 3 moxibustion, 1 acupressure) were included. Among 39 acupuncture studies, 35 used acupuncture as sole intervention. Sham treatment was the most common intervention for control group, followed by no intervention. Various outcome including pain, disability, quality of life, range of motion was used as outcome measurement. The effect of acupuncture and moxibustion was different depending on the type of control and outcome measurement. The most commonly used method in acupuncture for neck pain was GB21, SI3, GB20, LI4, BL11 acupoints, 10~30 mm insertion depth, 20~30 retention time, and 1~2 times per week. Conclusions : Analyzing the details of acupuncture and moxibustion treatment could be helpful for researches and clinics. Further studies should consider the characteristics of study design, intervention, and outcome to assess the effect of TKM.

As a result of surveying the process for sewing, the problems involving the outlook of sewn apparels were error off the standard dimensions and uneven sizes, which verifies the need for urgent technological guidance and development. On the other hand, the majority of the businesses were operating their sewing machines at the speed of 2,000 rpm or higher. Such a conventional working method may not well reflect the properties of the stretch fabrics, causing poorer quality products. Moreover, most of the businesses were using the ball-point needles which should be replaced with appropriate ones for stretch fabric. The types of feed dog which were used most were Drop feed, Union feed, Confound feed, Differential feed in their oder. Anyway, the automatized dog should urgently replace these inefficient ones for stretch fabric. Meanwhile, the types of presser foot which were used most were Plain foot, Teflon foot, Roller foot, Ring foot in their order, which also necessitates their replacement which Teflon foot. 2. As a result of surveying the process for finishing and inspection, while the causes scores less than 3 points, those due to pressers scored more than 3 points. This results suggests that a technological guidance is needed for the pressing work. Lastly, the causes of defect due to poor outlook attributable to such notions as button or zipper and those due to the uneven sizes scored more than 3 points, which suggests that the entire of needle works should be reformed through scientific research and technological guidance.

The aim of this study was to evaluate the effect of recombinant bovine somatotropin (bST; Boostin-S, LG Chem) treatment with FSH (Super OV) or PMSG on superovulatory response for transvaginal ultrasound-guided oocyte retrieval (TVR) in calves. Eight Korean Native Cattle(KNC) heifer calves; 150 to 240 days old; were randomly assigned to four treatment groups: 1) FSH(75 mg); 2) FSH (75 mg) + bST(500mg) 3) PMSG(1;000 IU); 4) PMSG(1, 000 IU) + bST(500 mg). Experimental calves in group 1 (n=2) and 2(n=2) were weekly superovulated for 4 consecutive weeks with daily injection of FSH for 3days and the next day subjected to TVR session. Animals in group 3 (n=2) and 4(n=2) were weekly stimulated for 4 consecutive weeks with a single dose of 1, 000 IU PMSG. TVR was performed on 72 hours after PMSG injection. Calves in group 2 and 4 was received injection of 500 mg of bST every 10 days. At each TVR session, follicle number and size were recorded; the oocytes collected and graded according to cumulus and cytoplasm investment. Collected oocyte were determined viable oocyte according to morphological quality with granulation of oocyte and number and status of cumlulus cells. IVM and IVF were performed and assessed cleavage rate on day 3 after fertilization. A Sonovet 600(Medison, Co., Ltd) realtime ultrasound scanner with a 6.5 MHz convex transducer, fixed at the tip of 500 mm estended handle equipped with a needle guide was used in collecting oocyte. Differences between groups were analysed by chi-square test. The population of large follicle ($\geq$5 nun) and aspiration rate were not significant different among the 4 groups. But, the number of small follicles (<5 mm) and aspirated oocyte in the KNC calves treated with bST were 1.3~1.6 times higher than in KNC calves treat with FSH or PMSG alone. In conclusion, the administration of bST with FSH or PMSG at superovulation for TVR in calves was increase the nurnber of small follicle which was influenced the number of aspiratable follicle.

The purpose of this study was to investigate the clinical effects of Korean medical treatments combined with Embedding acupuncture on patients with supraspinatus tendon partial tear. We reviewed the medical records of 1 patients with supraspinatus tendon partial tear at Pureunsan oriental medical clinic from Oct, 2017 to November, 2017. The patient received embedding acupuncture therapy and oriental medical therapy. To evaluate the efficacy of the treatments, the patient was asked to complete a Visual analogue scale(VAS) and the Shoulder pain and disability index during treatment period. The VAS of the patient decreased more than the screening period. The SPADI change of the embedding acupuncture group were greater than non treatment period. Embedding therapy combined with Korean medical treatment might be effective in reducing pain and improving the life quality of patients with supraspinatus tendon partial tear. We hope that further studies will be done to produce more clinical data and ensure effective application of these results.

Objectives : This study aims to review randomized controlled trials on acupuncture for shoulder pain according to Jadad Scale and revised STRICTA. Methods : Seven electronic databases including PUBMED, SCOPUS, RISS were searched for randomized controlled trials (RCT) of acupuncture for shoulder pain. Results : 16 RCTs were included: 14 were published in English and 2 were published in Korean. According to Jadad scale, 15 RCTs had high quality. However, most of the studies could not meet the double blindness criteria. All RCTs meet 12.9 items on average in STRICTA. Conclusions : This systematic review shows four conclusions as follows. Traditional Chinese Medicine is often used in style of acupuncture. Spots of LI15, TE14, GB21 and LI11, stainless steel needle($0.3mm{\times}40mm$), 20 retention time, manual stimulation, $Deqi$, and 2 times a week treatment (total 12) are often used. Double-blinded clinical trials needs to be conducted. It is controversial to use minimal acupunctures on controlled groups of RCTs on acupuncture for shoulder pain. Description about practitioner's background needs clarifying.
