  • This paper focused on studies of Noneo Jilseo("論語疾書") written by Lee Ik, also known as his honored name, Seong Ho(星湖). Seong Ho(星湖) also had left 10 types of exegetical commentary other than Noneo Jilseo("論語疾書"). The reason for choosing Noneo Jilseo("論語疾書") was that the teachings of Kongzi(孔子) were contained in Noneo("論語"). Also when we understand the Analects of Kongzi(孔子) correctly, we will be able to understand other Confucian Canons accordingly. Seong Ho(星湖) recommended Zhuzi(朱子) pronounced Noneo Jipju ("論語集註") as a critical commentary on the Analects. That is because there are no writings that had considered pupils' opinions and all of the various situations as much as Noneo Jipju ("論語集註"). For this reason, Noneo Jipju ("論語集註") could play a role as an excellent text. However, it is not just quality of the book that matters. While reading the main body, there is an author's comment, saying "For now, I write down my skeptical point of view." With this short note, the author expressed that "Collected Annotation on the Analects" was not necessarily the best teaching. This is the consequence of 'doubt.' We should be skeptical about the Analects of Confucius. That is not to say that the Analects are unconditionally bad. Seong Ho(星湖) expounded that the beginning students should regard Noneo Jilseo("論語疾書") as their textbook, but do not cling only to the disciplines elucidated in the book. Seong Ho(星湖) had written Noneo Jilseo("論語疾書") in order to help people to understand Confucius correctly. Although this book was written during his early professional years, Seong Ho(星湖) had grasped the essence of teaching precisely. Then, what is the essence? That is 'Doubt.' Innate factors therein can be correctly understood through 'Doubt.' In this context, Seong Ho(星湖) had made such comment as "For now, I write down my skeptical point of view." To understand the opinions of Confucius correctly, this process that being doubtful about the text is necessary. The Analects of Confucius are just similar to a coded message. To know accurately about the code, it is necessary to start from 'Doubt' at the first. Such a "Doubt" shall be a key to decrypt the coded messages further.

  • 'Pil-dam-chang-su-jib'(collection of conversation by writing about poetry or sentences) which was remained in Japan through the dispatching of Tong-sin mission belong to the Joseon dynasty is a valuable historical records directly to verify sincere relationships with Korea and Japan in the past. At the center of the 'Pil-dam-chang-su-jib', a conversation of senators who was technocrat both countries at that time was not a little contained. Because they need to exchange information and opinions which they had been curious at an appointed hour, the most impending medical problems of that period had to be brought out in the senator's 'Pil-dam-chang-su-jib' and the value of material is high as much. If you examine the 'Pil-dam' records which was exchanged from senators to senators of both countries at that time, you can directly confirm the universality and difference of the medical science and medicine tradition of various East Asian countries. The purpose of a paper was in consolidation to a base of translation and investigation hereafter to consider the characters embodied in medical conversation in the first half of $18^{th}$ centuries. '~ Rok(錄)' can be an opportunity to organize the customs history through the studying an illness, medicines and a remedy. The necessity of the investigation about medical related conversation by writing is in this place. '~ Ui-dam(醫談)' is considering with the all factors above, the first half of 18th century's medical conversation materials are certificated remarkably valuable materials to the cultural history around the physician at that time. '~ Pil-ur(筆語)' is to use of questions and answers form gives presence and reality at the conversation by writing. So, conversation was let the readers to gain the feeling of movement. Also, the contents are substantially reflected the long history of Eastern medical and revealed medical science, treatment reality at that time. Not correspondent with normal collection of conversation by writing, the medical conversation by writing shows a special quality at rich material to confirm the technocrat's identity. The first half of $18^{th}$ century medical conversation by writing had been a foundation of the rational description system at the coming medical conversation to change the description system according to the envoy's coming situation.

  • Objectives : The purpose of this study is to investigate the characteristics of depressive patients who admitted to general hospital. We examined the clinical characteristics of patients who were referred to the Department of Psychiatry as depressive symptoms, according to the type of consultation request, and comparing 'with re-consultation' and 'without re-consultation' groups. Methods : We performed a retrospective chart review of 4,966 inpatients who were referred to the Department of Psychiatry from August 2005 to December 2011. Results : For about 6 years, among the inpatients referred for psychiatric consultation, a total of 647 patients were referred for depressive symptoms, accounting for 13.82% of the total consultations. The average age of depressive patients was 58.6 years, which was higher than the average of 56.4 years of overall patients. Among the depressive patients, 275 patients were included in 'with re-consultation' group and there was no statistically significant difference when comparing 'with re-consultation' group and 'without re-consultation' group. However, there was a difference in the tendency of the two groups in the type of consultation request. 'With re-consultation' group was in the order of frequency of consultation type 3-2-1, whereas the 'without re-consultation' group was in the order of frequency of consultation type 2-3-1. Conclusions : The group of inpatients who were referred for depressive symptoms in general hospital showed the largest proportion of the group of patients referred to the Department of Psychiatry. 'With re-consultation' group had a higher rate of re-consultation due to the occurrence of new symptoms after hospitalization compared to 'without re-consultation' group. Therefore, doctors in each department and psychiatrists should pay attention to the depressive symptoms of inpatients and actively discuss treatment plans to improve the quality of medical services, identify risk factors, and make efforts to intervene early if necessary.

  • This study was carried out to generate various images of railroad surfaces with random defects as training data to be better at the detection of defects. Defects on the surface of railroads are caused by various factors such as friction between track binding devices and adjacent tracks and can cause accidents such as broken rails, so railroad maintenance for defects is necessary. Therefore, various researches on defect detection and inspection using image processing or machine learning on railway surface images have been conducted to automate railroad inspection and to reduce railroad maintenance costs. In general, the performance of the image processing analysis method and machine learning technology is affected by the quantity and quality of data. For this reason, some researches require specific devices or vehicles to acquire images of the track surface at regular intervals to obtain a database of various railway surface images. On the contrary, in this study, in order to reduce and improve the operating cost of image acquisition, we constructed the 'Defective Railroad Surface Regeneration Model' by applying the methods presented in the related studies of the Generative Adversarial Network (GAN). Thus, we aimed to detect defects on railroad surface even without a dedicated database. This constructed model is designed to learn to generate the railroad surface combining the different railroad surface textures and the original surface, considering the ground truth of the railroad defects. The generated images of the railroad surface were used as training data in defect detection network, which is based on Fully Convolutional Network (FCN). To validate its performance, we clustered and divided the railroad data into three subsets, one subset as original railroad texture images and the remaining two subsets as another railroad surface texture images. In the first experiment, we used only original texture images for training sets in the defect detection model. And in the second experiment, we trained the generated images that were generated by combining the original images with a few railroad textures of the other images. Each defect detection model was evaluated in terms of 'intersection of union(IoU)' and F1-score measures with ground truths. As a result, the scores increased by about 10~15% when the generated images were used, compared to the case that only the original images were used. This proves that it is possible to detect defects by using the existing data and a few different texture images, even for the railroad surface images in which dedicated training database is not constructed.

  • The grade and price of Lentinula edodes largely differs in preference depending on the product area and seasonal factors. The product amount of autumn L. edodes was higher than that of spring L. edodes, but high quality, which is divided into "Hwago" is low in preference. Mostly, the autumn L. edodes is obtained as powder; hence, it is necessary to develop a processing method to utilize its flavor and aroma at an affordable price. Additionally, we estimated the content of 𝛽-glucan, ergosterol, vitamin D2, reducing sugars, and free amino acids and evaluated the anti-inflammatory activity of saccharification powder of log-cultivated L. edodes. In the saccharification powders obtained via 7 min of UV irradiation of log-cultivated L. edodes, 𝛽-glucan and vitamin D2 contents were found to be the highest, whereas ergosterol content was found to be the lowest. The content of reducing sugars ranged from 62.4 mg/L to 68.2 mg/L. The free amino acids were higher in these saccharification powders than in the control. Subsequently, RAW 264.7 cells were treated with different concentrations (10, 50, 100, 200, 300, and 500 ㎍/mL) of the saccharification powders of log-cultivated L. edodes obtained via different UV irradiation time applications. The cells showed good viability; the anti-inflammatory effect was found to be the highest at 7 min UV irradiation. Therefore, 7 min of UV irradiation was determined to be the optimum condition for manufacturing saccharification powders of log-cultivated L. edodes. Hence, saccharification powders of log-cultivated L. edodes may be used as a raw material for natural sweeteners, food additives, and in the food industry.

  • Image matching is a crucial preprocessing step for effective utilization of multi-temporal and multi-sensor very high resolution (VHR) satellite images. Deep learning (DL) method which is attracting widespread interest has proven to be an efficient approach to measure the similarity between image pairs in quick and accurate manner by extracting complex and detailed features from satellite images. However, Image matching of VHR satellite images remains challenging due to limitations of DL models in which the results are depending on the quantity and quality of training dataset, as well as the difficulty of creating training dataset with VHR satellite images. Therefore, this study examines the feasibility of DL-based method in matching pair extraction which is the most time-consuming process during image registration. This paper also aims to analyze factors that affect the accuracy based on the configuration of training dataset, when developing training dataset from existing multi-sensor VHR image database with bias for DL-based image matching. For this purpose, the generated training dataset were composed of correct matching pairs and incorrect matching pairs by assigning true and false labels to image pairs extracted using a grid-based Scale Invariant Feature Transform (SIFT) algorithm for a total of 12 multi-temporal and multi-sensor VHR images. The Siamese convolutional neural network (SCNN), proposed for matching pair extraction on constructed training dataset, proceeds with model learning and measures similarities by passing two images in parallel to the two identical convolutional neural network structures. The results from this study confirm that data acquired from VHR satellite image database can be used as DL training dataset and indicate the potential to improve efficiency of the matching process by appropriate configuration of multi-sensor images. DL-based image matching techniques using multi-sensor VHR satellite images are expected to replace existing manual-based feature extraction methods based on its stable performance, thus further develop into an integrated DL-based image registration framework.

  • A sediment control dam is an artificial structure built to prolong sedimentation in the main dam by reducing the inflow of suspended solids. These dams can affect changes in dissolved organic matter (DOM) in the water body by changing the river flow regime. The main DOM component for Yeongju Dam sediment control of the Naeseongcheon River was analyzed through 3D excitation-emission matrix (EEM) and parallel factor (PARAFAC) analyses. As a result, four humic-like components (C1~C3, C5), and three proteins, tryptophan-like components (C2, C6~C7) were detected. Among DOM components, humic-like components (autochthonous: C1, allochthonous: C2~C3) were found to be dominant during the sampling period. The total amount of DOM components and the composition ratio of each component did not show a difference for each depth according to the amount of available light (100%, 12%, and 1%). Throughout the study period, the allochthonous organic matter was continuously decomposing and converting into autochthonous organic matter; the DOM indices (fluorescence index, humification index, and freshness index) indicated the dominance of autochthonous organic matter in the river. Considering the relative abundance of cyanobacteria and that the number of bacteria cells and rotifers increased as autochthonous organic matter increased, it was suggested that the algal bloom and consequent activation of the microbial food web was affected by the composition of DOM in the water body. Research on DOM characteristics is important not only for water quality management but also for understanding the cycling of matter through microbial food web activity.

  • Purpose: This study determined the relationships between maternal comprehensive feeding practices (CFP) and dietary practices of preschool children. Methods: Participants of the study were 227 mothers of children aged 3 to 5 years attending daycare centers and kindergartens in Seoul and Gyeonggi Province of Korea. The Comprehensive Feeding Practices Questionnaire was used to assess the maternal feeding practices. The Nutrition Quotient for Preschoolers (NQ-P) was measured to evaluate dietary practice and diet quality of children. Results: The balance of NQ-P for children was positively correlated with the modeling, restrictions for weight control, encouragement of balance and variety, pressure, and involvement among maternal CFP. Moderation of NQ-P was positively correlated with monitoring, modeling, teaching about nutrition, encouragement of balance and variety, environment, and involvement among maternal CFP. However, it was negatively correlated with emotion regulation, food as a reward, and child control in maternal CFP. Among maternal CFP, the environment of NQ-P was positively correlated with monitoring, modeling, teaching about nutrition, encouragement of balance and variety, environment, and involvement, and it was negatively correlated with emotion regulation. As a multiple regression analysis, maternal CFP that positively predicted balance of NQ-P indices were restricted for weight control, pressure, and involvement. Among maternal CFP, encouragement of balance and variety, and environment were positive predictors, while food as a reward, and child control were negative predictors for the moderation of NQ-P. Items of maternal CFP positively predicting environmental factors of NQ-P were monitoring and environment. Conclusion: Mothers are recommended to practice dietary guidance to their children, such as monitoring, modeling, teaching about nutritional information, recommendation of balance and diversity, healthy eating environment, and participation in meal plan and preparation, while they are advised not to conduct any adverse dietary guidance such as emotional control, compensation with food, child control, and food coercion.

  • This study was conducted to investigate the utilization and satisfaction of meal-kits according to food-related lifestyle among total 357 adults who had experience in using meal-kits. This study can provide basic data for effective menu composition and directions toward improvement. The participants of the study were classified into 5 groups 'health-type group', 'economic-type group', 'safety-type group', 'tasty-type group' and 'convenience-type group'. The 'tastye-type group' were found to spend more on purchasing meal-kits than other groups with the higher proportion(36.66%) of spending '30,000-50,000'won(p<0.05), which is the highest price category. The important factors that contributed to purchasing a meal-kits were 'taste'(50.98%), and 'economic-type group' showed the highest tendency of considering taste (58.46%). About half(49.02%) of the respondents preferred 'Korean-food' for meal-kits as for the type of food. All groups highly preferred 'meat'(42.58%) as the main ingredient, particularly the 'tasty-type group'(53.33%)(p<0.001). The 'tasty-type group' showed the highest satisfaction on 'convenience of cooking'(4.05), and 'convenience-type group' showed the lowest satisfaction on the 'origin of ingredient'(2.98) among groups (p<0.01). The overall response indicated that most respondents are willing to use meal-kits in the future (97.20%); and 93.28% of respondents would recommend the purchase of meal-kits to others, where 'convenience of cooking/purchase' was the factor contributing most for recommending(67.23%). Taken together, 'taste' was the most important factor for all groups. And 'Convenience of cooking' was the factor contributing to satisfaction most while 'origin of ingredient' contributing the least. It is recommended for the growth of meal-kits industry, to improve the quality of the meal-kits products and develop various menus.

  • Purpose: Conditions that limit activity constitute one of the important factors that threaten the health of the elderly. This study sought to analyze the dietary habits and nutritional intake status of the Korean elderly who were faced with activity limitations. Methods: Utilizing data from the 2019 Korea National Health and Nutrition Examination Survey, we classified 1,383 elderly people aged 65 and over into 2 groups: those with activity limitations (n = 222, LG) and those without (n = 1,161, NG). We conducted a comparative analysis of the general characteristics, dietary habits, intake of major food groups, energy, and major nutrients. The nutrient adequacy ratio (NAR), index of nutritional quality (INQ), and healthy eating practices were also analyzed. Complex sampling analysis was utilized for all the analyses with energy intake and socio-demographic variables adjusted. Results: The average age (73.8 years) of members of the LG was higher than those of the NG (72.6 years; p = 0.010). A higher percentage of participants in the LG lived alone (28.1%) compared to those in NG (17.2%; p = 0.004). The LG participants tended to regard their health status as "bad" or "very bad" (62.7%) more often than those in the NG (19.3%; p < 0.001). The LG subjects ate breakfast less frequently (p = 0.054) and ate out significantly less often than the NG subjects (p < 0.001). The LG subjects ate more grain (p = 0.001), fewer seeds (p = 0.014) and vegetables (p = 0.039). Carbohydrate made up a large percentage of their energy intake (p = 0.026). The LG subjects had significantly lower NARs of energy (p = 0.021), protein (p = 0.031), and riboflavin (p = 0.037). The LG participants also had a significantly lower rate of healthy eating practices (22.7%) compared to those in the NG (37.8%; p < 0.001). Conclusion: Activity-limited elderly, despite their need for appropriate dietary management, were poorly nourished. They were likely to live alone, thereby making it hard to provide them with social support. Hence, there is a need to provide nutrition education and policy support for the elderly bearing the burden of limited activity.
