Purpose: Pediatric acute appendicitis has a stable incidence rate in Western countries with an annual change of -0.36%. However, a sharp increase was observed in the Asian region. The Indonesian Health Department reveals appendicitis as the fourth most infectious disease, with more than 64,000 patients annually. Hence, there is an urgent need to identify and evaluate the risk factors and diagnostic modalities for accurate diagnosis and early treatment. This study also clarifies the usage of pediatric appendicitis score (PAS) for children <5 years of age. Methods: The current study employed a cross-sectional design with purposive sampling through demographic and PAS questionnaires with ultrasound sonography (USG) results. The analysis was performed using the chi-square and Mann-Whitney tests and logistic regression. Results: This study included 21 qualified patients with an average age of 6.76±4.679 years, weighing 21.72±10.437 kg, and who had been hospitalized for 4.24±1.513 days in Siloam Teaching Hospital. Compared to the surgical gold standard, PAS and USG have moderate sensitivity and specificity. Bodyweight and stay duration were significant for appendicitis (p<0.05); however, all were confounders in the multivariate regression analysis. Incidentally, a risk prediction model was generated with an area under the curve of 72.73%, sensitivity of 100.0%, specificity of 54.5%, and a cut-off value of 151. Conclusion: PAS outperforms USG in the sensitivity of diagnosing appendicitis, whereas USG outperforms PAS in terms of specificity. This study demonstrates the use of PAS in children under 5 years old. Meanwhile, no risk factors were significant in multivariate pediatric acute appendicitis risk factors.

Objective : This study aims to investigate the incidence of vestibular schwannoma (VS) and demographic characteristics in Korea using population-based National Health Insurance Service data. Methods : This study analyzed Korean National Health Insurance Service data from 2005 to 2020, based on the International Classification of Diseases, 10th version, Clinical Modification codes D333 and D431. Only those patients who had undergone magnetic resonance imaging and audiologic tests were considered definitive cases. Demographic variables included age, sex, treatment modality, hypertension, diabetics, dyslipidemia, smoking history, alcohol history, and income status. Results : The total number of VS patients was 5751. The average incidence rate was 0.71 per 100000 from 2005 to 2020, and the annual incidence rate increased from 0.33 in 2005 to 1.32 in 2019 but decreased to 0.80 in 2020. Incidence was highest in those aged 60-69 years (1.791) and lowest in those younger than 20 years (0.041). Incidence was higher in females, and the number of patients who received radiosurgery (46.64%) was largest compared to the wait and scan group (37.96%), microsurgery group (12.85%), or the group who received both (2.56%). Diabetes, dyslipidemia, and alcohol consumption increased the risk of VS, while cigarette smoking reduced the risk of VS. Conclusion : The incidence of VS exhibited an increasing trend from 2005 to 2019. Radiosurgery (46.64%) was the most common treatment modality. Diabetes, dyslipidemia, and alcohol consumption increased the risk of VS, while cigarette smoking reduced the risk of VS.

This study was conducted to evaluate the technical efficiency of Annual Chestnut production in South Korea. In this study, technical efficiency is the maximum possible production for which a certain amount of costs is inputted. For analysis on the technical efficiency we used output-oriented BCC Model, and then we analyzed correlation among input costs, production, gross income, net income, and market price per unit in order to determine the cause of variation in the technical efficiency. As study materials, we used statistics for the forestry production costs for 7 years from 2008 to 2014. The study results showed that the maximum possible production and actual production in 2008, 2009, and 2010 were 1,568 kg, 1,745 kg, and 1,534 kg by hectares in the order which were the same values. Consequently, the technical efficiency of those was all evaluated as 1.00. On the other hand, actual production from 2011 to 2014 was 1,270 kg 1,047 kg, 1,258 kg, and 1,488 kg by hectares in the order and the maximum possible production was 1,524 kg, 1,467 kg, 1,635 kg, and 1,637 kg by hectares in the analysis. From those values, the technical efficiency was evaluated in the following order:0.83, 0.71, 0.75, 0.91. The lowest value of the technical efficiency was 0.71 in 2012, and the values of this increased gradually since 2013. It is indicated that the cause of variation in the technical efficiency was related to the relationship between production and market price, and there was a negative correlation with r = -0.821 (p<0.05). The level of maximum available production per unit area was between 1,488kg in lower limit and 1,745 kg in upper limit, and the average was turned out as 1,548 kg.

The estimation of rice yield affects the income of farmers as well as the fields related to agriculture. Moreover, it has an important effect on the government's policy making including the control of supply demand and the price estimation. Thus, it is necessary to build the crop yield estimation model and from the past, many studies utilizing empirical statistical models or artificial neural network algorithms have been conducted through climatic and satellite data. Presently, scientists have achieved successful results with deep learning algorithms in the field of pattern recognition, computer vision, speech recognition, etc. Among deep learning algorithms, the SSAE (Stacked Sparse AutoEncoder) algorithm has been confirmed to be applicable in the field of forecasting through time series data and in this study, SSAE was utilized to estimate the rice yield in South Korea. The climatic and satellite data were used as the input variables and different types of input data were constructed according to the period of rice growth in South Korea. As a result, the combination of the satellite data from May to September and the climatic data using the 16 day average value showed the best performance with showing average annual %RMSE (percent Root Mean Square Error) and region %RMSE of 7.43% and 7.16% that the applicability of the SSAE algorithm could be proved in the field of rice yield estimation.

Objectives : This study is to make basic materials for an effective human resource management plan by understanding relationship between self-esteem and intention of transfer of dental hygienists who are working in dental diagnostic institutions and to contribute to human resource program development for promoting development into a dental hygienic profession. Methods : This survey was carried out for dental hygienists who are engaging in dental diagnostic institutions in part of Cheonbuk Area by survey researchers for 10 days from September 14 to September 24, 2011 by visiting dental clinics after respondents replied to a questionnaire after listening to explanations of study purposes. Total 210 copies of questionnaire were retrieved and 201 copies were used as materials for the final analysis excluding 9 copies with insincere replies. Results : 1. The total average grade for self-esteem of study objects was 32.83(${\pm}3.08$) points. The total average of intention of transfer was found to be 32.91(${\pm}7.50$) points. 2. Self-esteem by satisfaction on the current workplaces was shown to be high with 'very satisfactory'(p=0.028), which has significant difference statistically (p<0.05). 3. In the intention of transfer by general characteristics, 20-25 years ($35.15{\pm}7.17$) was higher than over 40 years old ($23.44{\pm}3.47$) by age to show significant difference statistically (p=0.000). As for married status, single ($34.42{\pm}6.64$) was found to have higher intention of transfer than married ($30.28{\pm}8.11$), which showed significant difference statistically (p=0.018). As for the education background, 3 year course college graduates ($33.49{\pm}7.25$) showed more intention of transfer than over undergraduate students ($22.75{\pm}9.43$) to show significance statistically (p=0.002) and in the working years 1~3 years ($34.40{\pm}7.07$) was found to have more intention of transfer than over 10 years ($25.13{\pm}5.08$) to be significant statistically (p=0.000). The annual income less than 25 million won ($34.10{\pm}6.54$) showed more intention of transfer than over 40 million won ($21.00{\pm}0.00$) (p=0.000). 4. Intention of transfer by satisfaction of current workplaces was found to be high in 'very unsatisfactory', which showed significant difference statistically (p<0.001). 5. Pure correlation between self-esteem and intention of transfer came into existence and intention of transfer was found to be higher as self-esteem is higher. Conclusions : Through results as above, intention of transfer of dental hygienists was found to be higher as self-esteem is higher. Various follow-up studies which are to perform empirical verification by analyzing various factors which can affect intention of transfer based on this and using them as control variables are thought to be tried.

The purpose of this study is to assist farmers in determining the optimal time for the shipment of stored apples by investigating the market trends, storage status and release dates of low-temperature stored apples. We surveyed 300 apple cultivation farms in Daegu, Gyeongbuk Province, which is the main producer of apples, and examined the cultivars, cultivation areas, storage conditions, and shipment status of apples. The main results are as follows: the proportion of apples cultivatedat different ripening times was surveyed. According to the results, the proportions of early, middle and late varieties were 78.3%, 63.7% and 96.0%, respectively. Also, 48.7% of the farm households surveyed had cold storage facilities. The average storage cost per apple box(15kg) was 978.3 won for self-storage and 1,771.8 won for consignment storage. For the six(6) months between November and April, the proportion of shipped apples was 91.6% of the total stored apples. The (average total?)annual apple shipment, including apples stored in general storage warehouses, was 744.4 boxes. The (average total?) annual shipment of cold storage apples was 616 boxes. The stored apples were mainly shipped to 'wholesale markets', which have the highest sales share, followed by 'production site collectors' and then 'supermarkets'. The most common shipping method of the apples was by general trucks, followed by low-temperature trucks, and finally by delivery services. The analysis of the factors influencing the decision to release apples by period showed that it was affected by the storage cost, loss rate, and customary shipping in the off-season(from May to August). On the other hand, in the general release season(from November to April), the statistically significant decision factors for the release of apples were the future expected price, storage cost and decision of the leading farmer groups. For farmers with a high share of general shipment, the deciding factors for the release of apples were the future expected price, storage cost, high income expectation, and decision by leading farmers.

The purpose of this study was to examine the influential factors for the quality of life of 151 dental hygienists. Average score were job stress $2.84{\pm}0.60$, social support $3.97{\pm}0.52$ and quality of life $3.18{\pm}0.35$ In terms of the quality of life, there were significant gaps according to age, marital status, the type of workplace, education and economic status. In social support significant difference were found according to age, the type of workplace and work system. In job stress, economic status made significant differences to that. Among the sub-factors of the quality of life, the dental hygienists who worked in public dental clinics led a life of higher quality than those who worked in hospitals in terms of physical and psychological health. In terms of social relationships, the dental hygienists who received graduate-school education led a life of better quality than the college graduates. In terms of environments, the 30-34 age group led a life of better quality than the 25-29 age group, and those who worked in public dental clinics led a life of better quality than the others. Those who received graduate-school education led a life of better quality than the junior-college graduates and the college graduates, and the group whose annual income was between 30 and 39 million won led a life of higher quality than the others. In terms of the overall quality of life, the group that worked for five days a week was ahead of the other that worked for five days a week. As a result of analyzing what factors affected the quality of life, emotional support, material support were identified as the variables to have a significant impact on that.
