Drug repositioning strategies using computer algorithms to respond quickly and effectively to emerging diseases, such as COVID-19, are gaining attention. In this work, we propose a novel approach for integrating multiple drug features using a multi-modal autoencoder and predicting ATC codes for a drug classification system. The similarity between drugs was computed based on their chemical structures, association with diseases or proteins, interactions between drugs, and drug side effect information. These features were integrated using a multi-modal autoencoder to create a single drug similarity network. ATC code prediction was also performed by forming a heterogeneous drug-ATC code network. When the experimental results were evaluated through cross-validation, the prediction accuracy was improved by 8.5% to an area under the curve (AUC) value of 0.914 when the merged similarity was used from an AUC value of 0.847 when a single similarity was used.

In this paper, we propose an IoT-enabled solution for tour photography services with small-size investment and resources in the travel and tourism industries, being able to impact on economic, social, and cultural values. An IoT-enabled camera is developed based on an open hardware and software platform complying with oneM2M, which can make traditional embedded systems oneM2M-compliant devices due to a middleware solution called TAS (thing adaptation software). IoT cameras deployed around photo zones in a tour site could be remotely controlled via an IoT gateway with a Web-based application on a smartphone. Users would perform a pan and tilt camera control if they want and then take and download a perfect photo picture (even though they are away from the tour site). We expect that the proposed solution will promote the deployment IoT-enabled technologies in tour and travel industries which are important parts of the tertiary sector. 본 논문에서는 관광 서비스 산업 분야에서 소규모 투자와 최소한의 인력만으로 경제적/사회적/ 문화적 효과를 이끌어낼 수 있는 관광 사진 촬영 서비스를 제공하기 위한 IoT 기반 솔루션을 제안한다. 오픈 하드웨어 플랫폼과 국제 IoT 표준인 oneM2M 기반 소프트웨어 플랫폼을 활용하여원격 제어가 가능한 IoT 카메라를 구현하고 이 과정에서 센서 및 액추에이터들을 oneM2M 표준디바이스로 변환이 가능한 미들웨어를 개발하였다. 포토존에 설치된 IoT 카메라는 oneM2M 기반게이트웨이에서 제공하는 웹앱 인터페이스를 통해 앵글 조절이 가능하고 촬영한 이미지를 사용자스마트폰으로 전달할 수 있다. 관광지 밖에서도 사용자에게 부여된 식별자를 이용하여 동일한 방식으로 촬영했던 사진 다운로드가 가능하다. 본 연구에서 제안한 솔루션을 발판으로 복합 서비스산업 중 하나인 관광 분야에서도 IoT 관련 기술들이 보다 활발히 적용되기를 기대한다.

Accurate measurement of functional similarity between proteins is crucial for the prediction of protein-protein interactions and drug-target interactions. In this study, the functional similarity between proteins was computed using Gene Ontology (GO). The similarity of terms was measured by word embedding methods, Word2vec and TF-IDF, which consider the term features and by a semantic similarity method that considers the relationship between terms. Thereafter, the measured similarity of terms was expanded to protein-protein similarity using annotations in GO. We proposed an integrated similarity that considers both features and relationships of the terms. Protein similarities measured by semantic similarity, Word2vec, TF-IDF, and integrated methods were applied to the prediction of protein-protein interactions and drug-target interactions. As a result, it was confirmed that the integrated similarity showed the best performance. 단백질 상호작용과 약물-단백질 상호작용에 대한 예측을 위하여 단백질 간의 정확한 기능적 유사도 측정이 중요하다. 본 연구에서는 유전자 온톨로지를 사용하여 단백질 간 기능적 유사도를 계산하였다. 용어 간 유사도는 용어의 특성을 고려하는 워드 임베딩 방법인 Word2vec과 TF-IDF, 그리고 용어의 연결성을 고려하는 의미론적 방법으로 측정되었다. 측정된 용어의 유사도는 유전자 온톨로지 내 어노테이션 데이터를 사용하여 단백질 간의 기능적 유사도로 확장되었다. 또한, 용어의 특성과 용어 간의 연결성을 모두 고려할 수 있는 통합된 유사도를 제안하여, 의미론적 방법, Word2vec, TF-IDF, 통합 방법으로 측정된 단백질 간 유사도를 단백질 상호작용과 약물-단백질 상호작용 예측에 적용하였다. 결과적으로 통합 방법에서 가장 우수한 성능을 보이는 것을 확인하였다.

이번 연구의 목적은 고교 유도선수들의 절기변화에 따른 최대산소섭취량 변화가 (salivary)타액 IgA에 미치는 영향을 목적으로 하였다. 이번 연구의 대상자는 남자 고교선수 16명(나이, 16.06 ± 0.77세; 신장, 171.56 ± 4.68cm; 체중, 74.43 ± 8.36kg; 체지방률, 13.55 ± 2.38%)을 동절기 12월과 하절기 8월에 2회 최대산소섭취량과 타액 IgA를 평가하였다. 최대산소섭취량 평가는 트레드밀 점증부하 운동방법을 이용하였으며, 측정 전 신체구성검사를 실시하였다. 안정 시 유도선수들의 타액 IgA 비교결과 동절기에 비해 하절기에 감소하는 경향을 보여주었으나 유의한 차이는 없었다. 운동직 후 계절별에 따른 타액 IgA 변화 결과 동절기에 비해 하절기 감소하는 경향을 보여주었으나 유의한 차이는 없었다. 오후 운동직후 타액 IgA 차이결과 동절기에 비해 하절기에 유의하게 감소하는 결과를 보여주었다(p<0.05). 최대산소섭취량 변화에 따른 동절기와 하절기에 따른 타액 IgA 변화의 관련성은 오후운동 직후 최대산소섭취량 1 mL/kg/min 증가에 따라 타액 IgA을 0.98 ug/mL 유의하게 감소시키는 경향을 보여주었다. 우리의 이번 연구결과를 토대로 유도선수들의 영양보조물 섭취시기의 필요성과 단기간 일시적 체중감량을 위한 고강도의 체력훈련 및 감소방법에 따라 면역기능 손상과 관련된 추가연구의 필요성을 확인할 수 있었다. The purpose of this study was to investigate effects of winter and summer season maximal oxygen uptake changes on salivary IgA level in high school Judoists. Sixteen male highschool Judoists participated in this study (age, 16.06 ± 0.77세; height, 171.56 ± 4.68cm; weight, 74.43 ± 8.36kg; percent body fat, 13.55 ± 2.38%) and two time measurement of maximal oxygen uptake and salivary IgA were conducted in December and August. Body composition measurement was conducted and then maximal oxygen uptake was tested by graded treadmill method. Resting salivary IgA level in summer season was decreased compared to winter season; however, there was no significant difference. IgA level at immediately after exercise in the morning was decreased in summer season compared to winter season although no significant difference was detected. IgA level at immediately after exercise in the afternoon was significantly decreased in summer season compared to winter season (p<0.05). Effects of winter and summer season maximal oxygen uptake changes on salivary IgA level showed a significant association with decreasing salivary IgA level by 0.98 ug/mL as increasing maximal oxygen uptake by 1 mL/kg/min. Based upon this study results, this study confirms the need of intake season of dietary supplements and the need of further study of immune function changes related to high intensity training in Judoists.

The abilities of external adaptation and internal integration of organization are extraordinarily required to survive and progress in dynamic environments. For this reason, it is quite necessary for the organizations to be managed in total perspective rather than separated into functional operations. But there are many problems which traditional structure and managerial techniques of organization can not solve. Therefore, cultural approach to organization is needed to provide some suggestions. In this sense, the objectives of this study is to build a managerial model which elevates the organizational effectiveness for the Korean business organizations by way of using cultural approach: This study tried to measure related variables by collection the perception toward respondents' own business organization. These perception variables include organizational culture patterns, organizational environments and oragnizational effectiveness. All these variables were tested to the organizations of 36 Korean businesses in 4 industries. The statistical models employed for this study are as follows: (1) T-test and One-way ANOVA are used in order to test the difference of oragnizational culture patterns of Korean business according to the environments and the industries. (2) Multiple Regression Analysis is employed to test the relationship of the organizational culture and the orgaizational effectiveness according to the environments. The results of this study are as follows: (1) The result of difference anlysis of organizational culture patterns is that all Korean businesses are, as recongnized by their organization, rationality culture-oriented not correlated to the external environments and the industries. But there is no significant correlation. (2) The analysis of the relationship between the organizational culture and the organizational effectiveness according to the environments showes they are significantly related. In other words, organizations with Affiliation Culture have had a higher organizational effectiveness than the others under a certain environment, and organizations with Progressive Culture have had a higher organizational effectiveness then the others under an uncertain environment.
