Purpose: This study aims to investigate the cusp variation pattern of the Korean mandibular second premolar and to determine the difference in tooth diameter and surface area using a virtual three-dimensional model. Methods: Dental casts from 69 students were scanned as a virtual dental models with a three-dimensional dental model scanner. Tooth diameter, absolute and relative individual areas, total crown area, the number of lingual cusps and central groove pattern were analyzed using RapidForm 2004. The Mann-Whitney U-test and the Kruskal-Wallis test were performed to verify sexual dimorphism, the difference in tooth diameter and surface according to the cusp variation pattern (α=0.05). Results: There was no significant difference except in buccolingual diameter (p<0.05) and buccolingual diameter at the cervix (p<0.05). The relative surface area of the total clinical crown was 65.76% for the buccal half and 34.24% for the lingual half, with a ratio of 2:1. In the case of the presence of two lingual cusps, the ratio was 21.47% for the mesiolingual half and 14.12% for the distaolingual half, with a ratio of 3:2. The dominant central groove patterns of the second premolar were the H-pattern (42.0%), followed by the Y-pattern (37.7%), then the U-pattern (20.3%). The relative buccal half was largest in the U-pattern central groove and the relative lingual half was largest in the Y-pattern central groove (p<0.05). Conclusion: This study is significant in that it measured quantitative surface areas and the findings could be a meaningful reference to comprehend dental anatomy in Koreans.

Objectives: The public relies on the news media to understand health risks. To examine the surveillance function of Korean health journalism, this study compared the rank-order of the 10 most frequently diagnosed cancers with that of the 10 cancers most frequently covered by three major Korean newspapers. Methods: News stories published between 1999 and 2010 by the Chosun-Ilbo, Joong-Ang-Ilbo, and Dong-A-Ilbo were examined. Data on cancer incidence were collected using the epidemiological data published by a governmental public health institution. To compare the level of the crude rates and the amount of news coverage, rank-order correlation tests and regression analyses were employed. Results: A reduction in the rank-ordered correlation coefficient was observed despite an increase in the overall number of cancer news stories released. The significance of the correlation disappeared after 2006. The big difference of the rank order between the crude rate and the amount of news coverage was observed in the cancer of breast, uteri, thyroid, and gallbladder/biliary. Finally, the three newspapers did not follow the amount change in stomach, lung, liver, and uterine cervix cancer. The four cancers' rank orders of crude rate were lowering, signifying a reduction of the comparative dangerousness of the four cancers. Conclusions: The news media's customization of news content and the negative bias in journalism are suggested as possible influences on the news media's inaccurate representation of cancer risk.

According to the literatural study on the causes of Infertility in women, the results were as follows. 1. The causes of Infertility in women were arranged scholarly thoery during to Jin-Yuan era (金 元 時代) from Huang-Di-Nei-Jing(黃帝內經), and literatures after Ming-Qing era(明 淸 時代) divided and added one's own thoery since they choose preceding thoery. 2. In the Modern Medicine, the causes of Infertility in women are divided the product obstruction of Oocyte, the union obstruction of sperm and oocyte by abnormality of vagina, cervix, corpus, fallopian tubes, pelvic, and peritoneum, Endocrine factor, Immunologic factor, and Emotion factor. 3. In the Oriental Medicine, the causes of Infertility in women are attached importance to functional side as 'asthenia-cool of uterus'(子宮虛寒), 'deficiency of vital energy and blood'(氣血虛), 'deficiency of yin'(陰虛), 'impairement of seven emotion'(七情傷), 'disease of extra mierdians'(寄經病), and so forth; while on the other in the Modern Medicine, the causes of Infertility in women are attached importance to organic side as abnormality of uterus and ovary. 4. In the successive literatures, 'asthenia-cool of uterus'(子宮虛寒) occupied most frequency in the causes of Infertility in women and in the next obesity(體肥), 'deficiency of vital energy and blood'(氣血虛), menstrual irregularity(月經不調), deficiency of yin'(陰虛), 'impairement of seven emotion'(七情傷), emaciation(體瘦), 'disease of extra mierdians'(寄經病), and so forth occupied much frequency. 5. In the bodily form, obesity(體肥) and emaciation(體瘦) occupied comparatively more frequency.

Purpose: This research was done to compare obstetric pain, anxiety and cervical dilatation between an epidural analgesia group and a control group. Methods: Participants were assigned to the experimental or control group depending on their decisions for pain relief. Subjective / objective obstetric pain, anxiety level and cervical dilatation were measured and ANOVA was used for comparison of groups and paired t-test to make pre-post comparisons. Results: Homogeneity of pain, anxiety and cervical dilatation were assessed at the latent phase. Cervical dilatation was larger in the control group than the experimental group, at both the active and the transitional phase (F=22.9, p<.001; F=39.9, p<.001 respectively). The degree of pain and anxiety were not significantly different between the groups. Within the experimental group, subjective / objective pain and anxiety level were significantly lower post-analgesia compared to pre-analgesia in the active phase. All variables, except for sweating in the objective pain measurement, changed significantly at the transient phase. Conclusion: The results of this evidence-based research indicate that epidural analgesia while effective in relieving pain and anxiety may have an adverse effect on the cervix during labor stage I. Epidural analgesia should be used carefully during cervical dilatation in labor stage I.

Background: In patients with endometrial carcinoma, preoperative evaluation of exact staging has important prognostic and therapeutic implications. The incidence of pelvic and aortic lymph node involvement in endometrial carcinoma depends on grade of tumor differentiation and depth of myometrial invasion. Material and method: To evaluate whether MRI provides a preoperative assessment for staging of endometrial carcinoma, MRI was undertaken in 28 patients, a few weeks before operation. Myometrial invasion was devided in three categories, and involvement of cervix, adnexa, and pelvic cavity were classified. Results: The results of MR imaging were compared with these of pathology. The preoperative MRI staging of endometrial carcinoma was correct in 22 out of 28 patients. In the evaluation of myometrial invasion, the MR imaging underestimated in 4 cases and overestimated in 1 case. Conclusion: In patients with endometrial carcinoma, MR imaging is very useful in the assessment of the depth of myometrial invasion, stromal invasion of cevix, lymphatic & pelvic metastases and extent of the lesion.

We propose a new 3 dimensional labeling method based on slice information for the volume data. This method is named SIL (Slice Information based Labeling). Compare to the conventional algorithms, it has advantages that the use of memory is efficient and it Is possible to combine with a variety of 2 dimensional labeling algorithms for finding an appropriate labeling algorithm to its application. In this study, we applied SIL to confocal microscopy images of cervix cancer cell and compared the results of labeling. According to the measurement, we found that the speed of Sd combined with, CCCL (Contour based Connected Component Labeling) is almost 2 times higher than that of other methods. In conclusion, considering that the performance of labeling depends on a kind of image, we obtained that the proposed method provide better result for the confocal microscopy cell volume data.

Objective: This case series aims to report the efficacy and the safety of using snake venom pharmacopuncture (SVP) for chemotherapy-induced peripheral neuropathy (CIPN). Methods: Three heterogeneous cancer (1 endometrium, 1 cervix, and 1 prostate cancer) patients were referred to the East-West Cancer Center (EWCC), Dunsan Korean Medicine Hospital of Daejeon University, from August 02, 2017, to September 15, 2017, for treatment with SVP, and they were treated with SVP 4 times, 6 times, and 8 times, respectively. During the treatment period, the efficacy of SVP therapy was assessed by using the Numerical Rating Scale (NRS) and the Common Terminology Criteria for Adverse Events (CTCAE), and the stability was evaluated by using blood tests. Following each session, all patients were examined closely for any allergenic responses or adverse effects. Results: All patients showed noticeable improvements of their NRS and CTCAE scores. Except for bleeding and bruising at the SVP injection site, no major side effects were noted. One of the patients reported mild chilling and a sore throat after receiving the second treatment; those symptoms went away after a few hours. No hematologic toxicity, hepatotoxicity, or nephrotoxicity was found on the blood test. Conclusion: The results of this research suggest positive potential benefits of using SVP for treating patients with CIPN. Also, the excellent safety results of SVP seen in this research should lead to larger clinical trials aimed at developing SVP into a potential intervention for managing patients with the symptoms of CIPN.

The present study was carried out to produce in vitro fertilized embryos with immature follicular oocytes collected by transvaginal aspiration from Holstein cows. A simple aspiration apparatus consists of two stainless steel tubes, an inner tube (needle holder; 1.2cmdiameter, 55cm long) and an outer tube (1.5cm diameter, 4Scm long), and a hand-operated vacuum pump was used. Under epidural anesthesia, the needle guide was passed into the vagina of the cow to a point next to the cervix. An ovary was placed against the wall of the vagina over the end of the aspiration needle by rectal manipulation. As the needlepassed into the ovary, an assistant was asked to apply vacuum(l00mrnHg) and the ovary was manipulated back and forth in all directions over the needle. When all sites of the ovary was aspirated, the needle was withdrawn and the needle guide was moved to the other side of ovary and the procedure was repeated. When the oocyte aspiration procedure was finished, collected fluid was transported to laboratory. Oocytes surrounded with at least 1 layer of cumulus cells were matured, fertilized and cultured in vitro. The results were as follows; Ninety seven oocytes were collected by transvaginal aspiration from seventeen Holstein cows(5.7 /head). The number of oocytes surrounded with at least 1 layer of cumulus cells were 60(61.9%). Following in vitro maturation, fertilization and culture, the cleavage and development rate to morula+blastocyst were 83.3% and 30.0%, respectively. From this study, transferable in vitro fertilized embryos could be produced with imma- ture follicular oocytes collected by transvaginal aspiration from Holstein cows using a simple aspiration apparatus.

This study was aimed to determine the biometry of genital organs, incidence of gynecological disorders and pregnancy loss in Black Bengal goat (Capra hircus). Genitalia of 118 does were collected from local abattoirs. Biometric parameters of genital organs were measured and gross and histopathological examinations were carried out for detection of abnormalities. For gravid uterus, age of the fetus was determined by measuring crown-rump length. There was no significant difference in the length, width and weight of right and left ovaries (P>0.05). However, the number of follicles between left ($5.3{\pm}2.3$) and right ovaries ($7.4{\pm}2.7$) varied significantly (P<0.05). The mean length of right fallopian tube and uterine horn were not varied with those of left fallopian tube and uterine horn. The length of uterine body, cervix and vagina were $1.3{\pm}0.1cm$, $3.3{\pm}0.5cm$ and $6.8{\pm}1.3cm$, respectively. Overall, 29 (24.6%) genitalia had abnormalities. Fifteen genitalia (12.7%) had ovarian abnormalities including ovaro-bursal adhesions (6.8%), parovarian cyst (5.1%) and follicular cyst (0.9%). Uterine abnormalities were found in 12 genitalia (10.2%) and predominant uterine lesion was endometritis (6.8%) followed by adenomyosis (1.7%), hemorrhagic lesion on endometrial surface (0.9%) and cyst in broad ligament (0.9%). In addition, cyst in fallopian tube (0.9%) and vagina (0.9%) were recorded. The proportion of slaughtered pregnant goats was 15.3% (18/118). The pregnancy wastage was highest in the first month (50.0%) followed by second (33.3%) and third (16.7%) month. It can be concluded that ovaro-bursal adhesions, parovarian cyst and endometritis are the gynecological disorders of major concern in Black Bengal goat.

This study was performed to compare the efficacy between a DNA chip method and a Hybrid-Capture II assay (HC-II) for detecting human papillomavirus in patients with intraepithelial lesions of the uterine cervix. From May, 2005, to June, 2006, 192 patients with abnormal colposcopic findings received cervical cytology, HC-II and HPV DNA chip tests, and colposcopic biopsy or conization. We compared the results of HC-II and HPV DNA chip in conjunction with liquid based cervical cytology (LBCC) and confirmed the results of biopsy or conization. The sensitivity of the HPV DNA chip test was higher than HC-II or LBCC. The HPV DNA chip in conjunction with LBCC showed higher sensitivity than any single method and higher sensitivity than HC-II with LBCC. We confirmed that the HPV DNA chip test was more sensitive for detecting HPV in cervical lesions than HC-II, and that it would provide more useful clinical information about HPV type and its multiple infections.
