Purpose : To evaluate the clinical findings, prognosis and treatment strategy of patients with neuroendocrine carcinoma of cervix. Materials and Methods: Thirteen patients with neuroendocrine carcinoma of cervix were included in this study, as confirmed histologically and immunohistochemically at the Dongsan Medical Center, Keimyung University, between May 1944 and October 2001. The mean age of patients was 56 years with a range of 32 to 78 years of age. According to the FIGO staging system, there were 5 patients with stage IB carcinoma, 5 patients with IIA, and 3 patients with stage IIB. Four patients underwent radical hysterectomy with pelvic lymphadenectomy, 3 of these patients also received postoperative radiotherapy, and one patient underwent extrafascial hysterectomy after radiotherapy. Primary radiotherapy was done in 9 patients, and 3 were irradiated postoperatively. Nine patients received chemotherapy, 7 received neoadjuvant and 2 received concurrent chemoradiotherapy. The radical purpose of radiotherapy consisted of external irradiation to the whole pelvis (4,500 $\~$5,400 cGy) and intracavitary irradiation (3,000 $\~$ 3,500 cGy). Results : The mean follow up duration was 36 months with a range of 3 to 104 months. The overall 5-year survival rate was 61.5$\%$ and the 5-year survival rates for stage IB, IIA, IIB were 60.0$\%$, 60.0$\%$, and 66.7$\%$ respectively (p=0.99). Eight patients are still alive without disease, and all of the 5 patients with recurrence are dead due to distant metastasis. Conclusion : Neuroendocrine carcinoma of cervix is highly aggressive, with early lymphatic dissemination and a high rate of distant recurrence. Therefore, an aggressive therapeutic strategy Is required to obtain pelvic and distant disease control. Multimodal therapy should be considered at the time of Initial diagnosis.

Background: This study was conducted to determine the level of job satisfaction and patient safety cultural activities for dental hygienists and to determine the relationship between job satisfaction and patient safety cultural activities. Methods: A survey was conducted on 214 dental hygienists, and data from the final 180 were analyzed. Job satisfaction consisted of a total of 20 questions, and patient safety cultural activities included a total of 25 questions. The survey was conducted on a 5-point scale. Results: The average job satisfaction score of the study subjects was 3.44 points. Among patient safety cultural activities, infection control had the highest average score (4.12 points) and radiation safety management had the lowest average score (3.10 points). Patients with less than 3 years of clinical experience (4.01 points) had higher patient safety culture activity scores than those with 3 to 10 years of clinical experience (3.72 points) and those with more than 10 years of clinical experience (3.69 points). The level of patient safety cultural activities was statistically significantly higher as age, less clinical experience, and job satisfaction increased (p<0.05). Conclusion: In the case of dental hygienists, patient safety cultural activities must be carried out throughout the entire work, so an active will to practice patient safety cultural activities is necessary. In order to improve the performance of patient safety cultural activities, it is necessary to adjust the workload of dental hygienists to improve job satisfaction and create a work environment in which they can focus on patient safety cultural activities.
This study delves into the geopolitical tensions surrounding Ukraine throughout modern European history, aiming to shed light on its significance in geopolitical discourse. Since the 19th century, European powers, particularly the Anglo-Saxons and Germans, have formulated distinct geopolitical strategies concerning the Eurasian continent, with Ukraine at its focal point. The Crimean War and the German-Soviet War serve as key events to analyze these powers' geopolitical ambitions and interests. The British Empire, driven by its doctrine of thwarting land powers with sea power, intervened in the Crimean War against Russia. Its objective was to disrupt Russian dominance over Ukraine, thereby hindering Russian expansion into the Black Sea and Central Europe. On the other hand, the Third Reich of Germany, fixated on creating a European sphere exclusive from Anglo-Saxon sea powers and the Russian land power, initiated the German-Soviet War. This move aimed to secure a vast territory, including Ukraine, to facilitate expansion into the Caucasus and establish a buffer zone against the Soviet Union. Three key insights emerge from this analysis. Firstly, the absence of a dominant power rooted in Ukraine since the fall of the Principality of Kiev made geopolitical clashes inevitable. Secondly, these clashes ultimately result in a hollow victory for all involved parties, signifying the high costs and minimal gains of such confrontations. Lastly, the root cause of these clashes lies in the discord between exclusive geopolitical visions that fail to accommodate sustainable coexistence among diverse geopolitical spheres. In essence, the study underscores Ukraine's pivotal role in shaping European geopolitics and highlights the recurring clashes driven by competing visions of dominance and control over its territory. From the Crimean War to the German-Soviet War, the struggle for influence over Ukraine reflects broader geopolitical dynamics and the pursuit of strategic advantage by major powers. Ultimately, the study emphasizes the enduring significance of Ukraine in European geopolitics and the complexities inherent in managing its geopolitical tensions.

This study was carried out to evaluate the wheat cultivation system to reduce costs and mechanize wheat production. A field study was conducted for 2 years (2009 to 2010) at the National institute of crop science, Iksan, Korea. We used working system I and working system II for the experiment. Working system I is used a multiple machine attached with a spreader tractor (seeding, fertilization, seed coverage, and weed control functionality) and working system II is used a multiple machine with a tractor which works for simultaneous job when seeding step (seeding, fertilization, and seed coverage). Sowing to harvesting operation time is 118 hours/ha for mechanize with conventional planting. Working system I is a multiple machine and a combine machine with a tractor, which worked 26 hours/ha lower than conventional planting. Working system II is 18 hours/ha lower than conventional planting. The reduced work efforts of working system I and II were 78% and 85% respectively. The growth and yield of wheat according to working system I and II is lower than conventional planting. Therefore, a multiple machine needs to study for appropriate seeding rate. Mechanization cost in consideration of the mechanical break-even point when the working system I is 3.7 ha and working system II is 4.2 ha. The farm income is enhanced by working system I (778,110 won/ha) and working system II (849,930 won/ha). The results showed that application of a multiple machine lowered costs of wheat production.
This study was conducted to estimate the prevalence of constipation, bowel habits and nutrient intakes of college students. The subjects were 353 college students (166 males and 187 females) aged 19 to 29 years in Incheon area. The subjects were asked about bowel habits and dietary intake using questionnaires during march, 2008 and the prevalence of functional constipation (FC) was based on the Rome II criteria. The prevalence of FC in male and female students was 12.7% and 28.9%, respectively. The prevalence of self-reported constipation in male and female students was 12.0% and 36.9%, respectively. Both were higher in female students compared to male students. Among the subjects that have self-reported constipation, proportions of FC were 35.0% in male students and 55.1% in female students. Of subjects that did not self-reported constipation, the proportions of FC were 9.6% in male students and 13.6% in female students. Over 90% of respondents that self-reported constipation in male students, had neither visited a hospital and nor used laxatives or functional foods for constipation relief. Seventy five point three percent of male students, and 40.1% of female students, had a defecation frequency of over 5 times per week (p < 0.001). Ratios intaken under the estimated average requirement (EAR) of Vit A, Vit C, folic acid and Ca were over the 50% regardless of functional constipation. Mean daily consumption of total dietary fiber was 15.0 g/day in male students and 13.5 g/day in female students. According to these results, both functional constipation and self-reported constipation are more frequent in female college students and further studies are required in case-control study and related to psychological factors as well as nutrients to relieve of constipation.

Purpose : Surveillance for detecting and managing latent tuberculosis infection (LTBI) is a key component of tuberculosis control. The classic surveillance tool, the tuberculin skin test (TST), may have some limitations when used in the Bacillus Calmette-$Gu{\acute{e}}rin$ (BCG)-vaccinated population. The object was to perform a blood test $QuantiFERON^{(R)}$-TB Gold In Tube (QFT-G IT) based on the detection of interferon-$\gamma$ ($IFN-{\gamma}$) released by T cells in response to Mycobacterium tuberculosis-specific antigens, and to compare the efficacy of this new diagnostic tool for LTBI with that of TST. Methods : For six months, between October 1, 2006 and April 30, 2007, data were collected from 111 patients under 15 years of age at Severance Children's Hospital. TST and QFT-G IT tests were performed with children with or without contact histories of tuberculosis. In addition to these tests, we examined comparative data from 29 adults who had tuberculosis, to detect false negative rates in the QFT-G IT method. Results : Thirty-three children had household contact histories. In this group, 15% and 42% of cases were found to be positive using the QFT-G IT assay and TST, respectively. Agreement was low between these two tests (${\kappa}=0.39$). In the adult active tuberculosis group, the QFT-G IT false negative rate defined as a positive culture and a negative QFT-G IT result was 12.5%. Conclusion : In diagnosing LTBI in children, the usefulness of a whole-blood $IFN-{\gamma}$ assay employing TB-specific antigens will be revealed only by examining additional longitudinal clinical data; this study serves as a starting point in that process.
Purpose: This study was performed to examine the sanitary knowledge level and degree of HACCP (hazard analysis critical control point) practice in school culinary staff in order to provide basic information for improving hygiene of school meals. Methods: Exactly 305 culinary staff members were selected from elementary, middle, and high schools in 14 cities and rural areas, including whole administrative districts in Chungnam province. Surveyed schools were selected by convenience sampling, and one subject was selected randomly from each school. Surveys were taken by self-administered questionnaires developed by researchers and questionnaire were distributed and collected by postal mail. Results: Sanitary education administered by school dietitians to culinary staff was more frequent and longer in elementary schools, followed by middle and high schools (p < 0.001). Sanitary knowledge level and degree of HACCP practice, except for a few CCP or CP of culinary staff, were highest in elementary schools and middle school followed by high schools (p < 0.05), respectively. School class was negatively correlated with sanitary knowledge level of culinary staff (p < 0.01), and frequency of sanitary education was positively correlated with sanitary knowledge level of culinary staff (p < 0.01). Sanitary knowledge level of culinary staff was positively correlated with degree of HACCP practice (p < 0.01). School class, daily frequency of meal service, work experience, rice washing machine, and total score of sanitary knowledge were significant variables influencing degree of HACCP practice in culinary staff. Conclusion: The above results show that the following points should be considered to improve hygiene of school meals. Sanitary education should be administered more frequently by school dietitians to culinary staff, especially to those in high schools, which showed the lowest sanitary knowledge level and degree of HACCP practice. In addition, facilities and equipment required for HACCP practice should be supported in small-sized elementary schools.
BACKGROUND: For Non-Point Source(NPS) loads reduction, pollutant loads need to be quantified for major farming methods. The objective of this study was to evaluate impacts of farming methods on NPS pollutant loads from a paddy rice field during the growing season. METHODS AND RESULTS: The height of drainage outlet, amount of fertilizer, irrigation water quality were considered as farming factors for scenarios development. The control was derived from conventional farming methods and four different scenarios were developed based combination of farming factors. A field scale model, CREAMS-PADDY(Chemicals, Runoff, and Erosion from Agricultural Management Systems for PADDY), was used to calculate pollutant nutrient loads. The data collected from an experimental plot located downstream of the Idong reservoir were used for model calibration and validation. The simulation results agreed well with observed values during the calibration and validation periods. The calibrated model was used to evaluate farming scenarios in terms of NPS loads. Pollutant loads for T-N, T-P were reduced by 5~62%, 8~37% with increasing the height of drainage outlet from 100 mm of 100 mm, respectively. When amount of fertilizer was changed from standard to conventional, T-N, T-P pollutant loads were reduced by 0~22%, 0~24%. Irrigation water quality below water criteria IV of reservoir increased T-N of 9~65%, T-P of 9~47% in comparison with conventional. CONCLUSION(S): The results indicated that applying increased the height of drainage after midsummer drainage, standard fertilization level during non-rainy seasons, irrigation water quality below water criteria IV of reservoir were effective farming methods to reduce NPS pollutant loads from paddy in Korea.
