Objectives: The aim of this study was to understand the characteristics of herbal-drug-associated adverse events (AEs) reported in the internet newspaper articles and to take a countermeasure against the safety issue of herbal drugs. Methods: We searched the internet newspaper articles published from 2010 to 2014 in the 3 major portal sites in Korea, NAVER, DAUM, and GOOGLE. Search terms were the Korean words equivalent of 'herbal drug' and 'side effects'. Informations on the type and characteristics of suspected herbal drugs, AEs, and the patient records were extracted from the articles reporting the herbal-drug-associated AE occurred in Korea. Results: From 8,806 articles, a total of 36 AEs were found. The most frequently reported age group was 20s, and women outnumbered men. Obesity was the most common cause of administration. Doctors of Korean medicine clinic were the most commonly referred prescribers and purchasing route (11 cases). The most frequently mentioned medicinal herb was Ephedra sinica (7 cases) and the most commonly reported AEs were abdominal pain (8 cases), dizziness (6 cases), diarrhea (5 cases), and vomiting (5 cases) were followed in order. Ten cases were judged as serious AEs, and the others were not. Conclusions: Current customers demand health care providers to offer them sufficient information on the safety of herbal drugs. To satisfy their requirements, physicians of Korean medicine should be able to explain, predict, prepare, recognize, and deal with the herbal-drug-associated AEs. We propose an establishment of pharmacovigilance system for herbal medicine, in which doctors of Korean medicine are participated as important personnel, to collect and analyze the related AEs and offer credible information on the safety of herbal drug.
We examined the horizontal distribution of salinity and the concentrations of DIN and DIP after heavy rain-fall events in coastal areas of South Korea from Yeoja Bay to Narodo and from Gwangyang Bay to Geomodo to determine whether fresh water actually flows into areas of Cochlodinium polykrikoides red tides and to observe its effect on the growth of this organism after heavy rainfall. Following heavy rainfall (155 mm) in the Yeosu and Suncheon regions, the average salinity was 21 and 29 psu at Yeoja Bay and in the coastal waters of Narodo, respectively. After 126 mm of rainfall, the values were 19 and 25 psu in the coastal waters of Yeosu and Geomodo, respectively. This may have been caused by an influx of fresh water, after the rainfall event, into the open sea coastal areas around Narodo and Geomodo from the Dong and Seomjin Rivers, which are about 3540 km away. After the rainfall, the concentrations of $NH_4-N,\;NO_2-N$, and $PO_4-P$ were slightly increased; however, the concentration of $NO_3-N$ was greatly increased and diffused throughout the coastal areas of Narodo and Geomodo, which frequently experience C. polykrikoides blooms. The influence of $NH_4-N,\;NO_2-N$, and $PO_4-P$ on the occurrence of C. polykrikoidesred tides in coastal areas around Narodo and Geomodo after heavy rainfall does not appear to be great. Instead, the occurrence C. polykrikoides red tides in the coastal areas of Narodo and Geomodo seems to be facilitated by $NO_3-N$.

In this study we have used the data of various instruments onboard the THEMIS spacecraft to study the characteristics of the outer radiation belt during the ascending phase of solar cycle 24. The most astonishing result is that we discovered four long-term (a month or so) periods during which the belt has nearly disappeared. The first disappearance started late 2008, followed by reappearance in ~a month, and three more similar events repeated until early 2010 when the belt has reappeared. This is well revealed at 719 keV electrons, which is the currently available uppermost energy channel from the THEMIS SST observation, but also seen at even lower energies. Overall consistent features were confirmed using the NOAA-POES observations. The vanished belt periods are associated with extremely weak solar wind conditions, low geomagnetic disturbances (in terms of Kp and AE/AL), greatly suppressed wave (ULF and chorus) activities, greatly reduced storm and substorm activities (little source particle supply), and expanded plasmapause locations. The direct observations of such events shed light on the fundamental question of the origin of the radiation belt, which is the main focus of our presentation.
Objective: This study aimed to identify the status and risk factors of rituximab infusion-related adverse events (ADE) in rituximab-na$\ddot{i}$ve patients with cancer diseases. Method: A retrospective analysis using electronic medical records review was conducted. Inclusions were patients with a diagnosis of cancer disease with the initiation of rituximab-included treatment who were na$\ddot{i}$ve to rituximab during January 2011 to March 2013 at National Cancer Center (NCC) in Korea. Result: Total 110 patients, 582 cases of rituximab administrations, were reported in the study. About 57.2% of patients were 51-70 years old and evenly distributed between two genders and 72.7% were BMI less than $25kg/m^2$. All of study patients were diagnosed with non-Hodgkin lymphoma. Fifty patients (45.4%) and 54 cases (9.3%) were experienced rituximab infusion-related AEs even with conservative administration protocol at NCC. The most frequently occurring AEs were shivering followed by rash and itching. In single variant analysis, we found that the early stage of NHL, low exposure to rituximab administrations, high white blood cell counts, high lymphocyte counts, high absolute neutrophil count and low lactate dehydrogenase were associated with infusion-related AEs (p<0.05). The early stage of disease, high lymphocyte counts, low exposure to rituximab administrations were also related significantly with AEs in multiple variants analysis (p<0.05). Conclusion: Rituximab infusion-related AEs for patients who were na$\ddot{i}$ve to rituximab were still a concern with conservative administration protocol. The adverse drug reactions were significantly associated with early stage of NHL, higher lymphocyte counts and low exposure to rituximab administrations. The factors need to be considered with close monitoring to prevent rituximab infusion-related AE.
Community facilities in most rural villages have many problems in the aspect of their size or functions as well as they are generally too superannuated to support diverse community activities; which results in a low degree of inhabitants' satisfaction with community facilities, and inconvenience for using them. Therefore, it may carefully be said that it's time to need the established studies that are necessary with consider to community facilities which can reflect inhabitants' diverse activities. In this study, 5 places which the most common events among the major monthly events of total 25 rural villages were held were selected as the subject place for survey; and then investigated, by means of the participant observation method, the using behavior of inhabitants who used community facilities. Focusing on size, factors, and layout that were being faced by community facilities in most rural villages, This study investigated the number of users, the characteristics of traffic line and behavior, and the using behavior by group; through considering their correlation with the physical setting of community space, it deduced the problems of use; and it proposed the direction of improvement on the basis thereof. Therefore, this study will serve in the future as useful basic materials for designing a rural village's community facilities in consideration of size, factors and layout which can appropriately support inhabitants' community activities.
Objectives: The purpose of this study was to investigate the effect of weight loss in Korean Medicine (KM) obesity treatment combined with self-monitoring and to identify the relevant factors which are related to successful weight loss. In addition to this, adverse events reported by the patients were analyzed to assess the safety of KM treatments for obesity Methods: This was a retrospective observational study that analyzed the medical records of the patients that participated in the 10-week of KM treatment. All patients took herbal medicine for weight loss and were instructed to reduce calorie intake and adhere to self-monitoring. Clinical data including body weight were collected for evaluating the effect of the treatments. Behavior factors affecting weight loss were collected. The correlation between each factor and weight loss was analyzed. Adverse events (AEs) were collected at each time to evaluate the safety of the intervention. Results: One hundred eighteen patients' records were included in this study. The average weight loss was 7.64kg(74.59kg to 66.95kg). 94.9% of patients lost 5% or more of their initial weight. The degree of weight loss was identified to be related to self-assessment of diet control and self-assessment of appetite control. The average self-weighing frequency significantly increased(2.45 times/week before treatment and 4.70 times/weeks during treatment). Constipation, insomnia, and dizziness were found to be the most frequent AEs, and except for one case, most AEs were mild cases. Conclusion: From this study, we found that KM obesity treatment combined with self-monitoring showed significant weight loss without serious AE.

This study aimed to analyze the status of adverse events (AEs) in the treatment of musculoskeletal conditions/diseases using thread embedding acupuncture (TEA). Five electronic databases were searched to retrieve data on clinical studies published in the last 5 years (2016 to 2021). Of the 151 studies retrieved, 22 studies analyzed AEs and were selected for this review. There were no AEs reported in 6 studies (27.3%); of the remaining 16 studies, 4 studies (18.2%) reported AEs that were not related to TEA. The most common AEs reported in the Chinese studies were redness of skin with/without swelling and tingling sensation, and in the Korean studies they were stiffness, a foreign body sensation, and bruising. The percentage of patients with AE experience was 5.1% in the Chinese studies and 19.9% in the Korean studies. The discrepancies between the findings in the Chinese and Korean studies may be attribute to differences in the diameter of needles, thread materials, TEA treatment procedure, and evaluation methods for AEs. Most of the reported AEs were of a mild status and did not last for a long time. However, further research on the clinical course after TEA treatment is needed.

In intelligent transportation systems, traffic management is an important task. The accurate forecasting of traffic characteristics like flow, congestion, and density is still active research because of the non-linear nature and uncertainty of the spatiotemporal data. Inclement weather, such as rain and snow, and other special events such as holidays, accidents, and road closures have a significant impact on driving and the average speed of vehicles on the road, which lowers traffic capacity and causes congestion in a widespread manner. This work designs a model for multivariate short-term traffic congestion prediction using SLSTM_AE-BiLSTM. The proposed design consists of a Bidirectional Long Short Term Memory(BiLSTM) network to predict traffic flow value and a Convolutional Neural network (CNN) model for detecting the congestion status. This model uses spatial static temporal dynamic data. The stacked Long Short Term Memory Autoencoder (SLSTM AE) is used to encode the weather features into a reduced and more informative feature space. BiLSTM model is used to capture the features from the past and present traffic data simultaneously and also to identify the long-term dependencies. It uses the traffic data and encoded weather data to perform the traffic flow prediction. The CNN model is used to predict the recurring congestion status based on the predicted traffic flow value at a particular urban traffic network. In this work, a publicly available Caltrans PEMS dataset with traffic parameters is used. The proposed model generates the congestion prediction with an accuracy rate of 92.74% which is slightly better when compared with other deep learning models for congestion prediction.
Recently developed illite-age-analysis(IAA) approach was applied to determine the fault-reactivated events for the Inje fault that cut through Precambrian biotite granitic gneiss with NNE-SSW trend in the middle of Korean peninsula. Three distinct fault-reactivated events of shallow crustal regime were recognized using the combined approach of optimized illite-polytype quantification and K-Ar age-dating of clay fractions separated from 4 fault clay samples: $87.0{\pm}0.12Ma$, $65.5{\pm}0.05$ and $66.6{\pm}1.38Ma$, $45.6{\pm}0.15Ma$, respectively. As well, $2M_1$ illite ages of 193~196 Ma and $254.3{\pm}6.96Ma$ were discernible, which may be related to the fault-activated time in the relatively deep crust. The study results suggest that the Inje fault would be firstly formed at $254.3^{\circ}$${\ae}6.96Ma$ and sporadically reactivated in shallow regime since about 87 Ma. These reactivation events in shallow regime might be due to the Bulguksa orogeny that would be strongly influenced in Korean peninsula at that time.
This study examines the social meaning of the CosPlay, the growth potential of CosPlay culture and its effect on the related industry through the perspectives and language of the youths who enjoy CosPlay, based on the ethnographic research. Also, this study presents a comparative description of Korea and Japan CosPlay culture by the ethnographic methodology whose purpose is to define relationship of cause and effect with phenomenon. For further step, this study plans to emphasize the need to link culture, clothes and related industry in order to create a cultural environment where diversity co-exists. CosPlay is the mania culture of Japan that emulated the Halloween party of the West and that developed the party into a unique form. In Korea, this practice was accepted for the first time among a handful of youths, starting from the 1990s, after which, it was introduced to the masses while holding CosPlay related events. While CosPlay is succeeded as an industry in Japan, CosPlay in Korea is considered childish play due to the Korean culture of considering cartoon as a childish and low class genre which is enjoyed by youths. CosPlay in Korea faces the following changes: aging of the members who comprised the CosPlay culture at the initial stage; population increase, centered on middle and high school students; interest of the government and the businesses that wish to produce economic wealth by organizing CosPlay events into events for youths; and changes in the environment that comprised the surrounding of the CosPlay culture. CosPlay is an honest play that demonstrates one's effort on the stage through performance. Moreover, most of the middle and high school students who comprise the CosPlay culture demonstrate similar characteristics as mania type of people when it came to the reason that they enjoy CosPlay. However, they did not consider CosPlay culture as an important aspect of their lives. Instead, most of them said that they participate to relieve stress. Thus, they have the potential to move onto another form of youth culture that may appear more attractive to them. To them, it is not the CosPlay culture that is important, but the fact that CosPlay provides a forum where they can freely engage in play.
