클라우드 컴퓨팅은 인터넷 기술을 활용하여 다수의 고객들에게 높은 수준의 확장성을 가진 IT 자원들을 서비스로 제공하는 컴퓨팅이다. 데이터 센터내의 가상화된 스토리지를 할당 받아 개인의 PC 환경처럼 사용하는 클라우드 컴퓨팅 환경 에서 사용자들은 자신의 데이터가 저장된 위치, 현재 리소스 사용률 등의 정보를 필요로 한다. 그러나 현재 클라우드 컴퓨팅 환경에서는 이런 정보들을 사용자에게 서비스하지 않는다. 따라서 본 논문에서는 데이터 센터내의 할당 받은 사용자의 스토리지 리소스 사용량, 서비스 정보, 데이터 전송률을 모니터링 하여 실시간으로 서비스 해주는 클라우드 컴퓨팅 환경에서 사용자를 위한 모니터링 서비스를 제안한다.

The evaluation items to assess the consumer needs are thought to be varied depending on their age, education and income. It should be noted that consumer needs are getting too diversified to notice them in time due to the rapid economic, social and cultural development. It is, therefore, considered improper to try to assess the level of consumer satisfaction and correct consumer needs by employing one evaluation method for the vastly diversified consumer types. This research is going to conduct a written questionnaire survey to the apartment dwellers in order to identify like dweller groups according to their age, income and education. Then the scope of personal characteristics of each group will be identified and the importance assessment model will be developed. Then the items on the POE will be weighted according to the assessed importance. Finally a method of developing the customer satisfaction index will be produced to quantify how much the consumers are satisfied with the project.

Analyzing breast cancer patient files is becoming an exciting area of medical information analysis, especially with the increasing number of patient files. In this paper, breast cancer data is collected from Khartoum state hospital, and the dataset is classified into recurrence and no recurrence. The data is imbalanced, meaning that one of the two classes have more sample than the other. Many pre-processing techniques are applied to classify this imbalanced data, resampling, attribute selection, and handling missing values, and then different classifiers models are built. In the first experiment, five classifiers (ANN, REP TREE, SVM, and J48) are used, and in the second experiment, meta-learning algorithms (Bagging, Boosting, and Random subspace). Finally, the ensemble model is used. The best result was obtained from the ensemble model (Boosting with J48) with the highest accuracy 95.2797% among all the algorithms, followed by Bagging with J48(90.559%) and random subspace with J48(84.2657%). The breast cancer imbalanced dataset was classified into recurrence, and no recurrence with different classified algorithms and the best result was obtained from the ensemble model.

Objectives : This study aims to examine the 13 diagnostic criteria symptoms of panic disorder in Korean Medicine and to establish a literature basis for treating panic disorder in the clinical setting. Methods : Symptoms in Korean Medicine corresponding to each diagnostic criterion were comprehensively reviewed based on the Uihagimmun(醫學入門) and the Donguibogam(東醫寶鑑). Treatments were investigated as well. Results : According to Korean Medicine, panic disorder is believed to be caused by the stagnation of qi, leading to the retention of phlegm and fluids. Conclusions : Yijintang(二陳湯) can serve as a fundamental prescription for treating panic disorder, and it can be easily adapted to each patient's symptoms through modification of the ingredients.

본 연구는 건강 이상 감지를 위해 보폭 이상을 판단하는 신발과 어플리케이션을 연동하여 알츠하이머 등의 뇌손상으로 인한 보폭 이상을 미연에 예방하고 개선하는데 목적이 있다. 보행 이상 감지를 위해 보폭을 판단하는 건강진단신발은 측정부가 설치되며, 알츠하이머 등의 뇌손상에 의해 보폭이 줄어드는 경우 보폭이 좁아지는 것을 경고함으로써 장소와 시간에 구애받지 않고 신발착용자 스스로 보행 진단 및 교정이 이루어질 수 있다.

Recently, as deep learning technology has developed, various deep learning technologies have been introduced in handwritten recognition, greatly contributing to performance improvement. The recognition accuracy of handwritten Hangeul recognition has also improved significantly, but prior research has focused on recognizing 520 Hangul characters or 2,350 Hangul characters using SERI95 data or PE92 data. In the past, most of the expressions were possible with 2,350 Hangul characters, but as globalization progresses and information and communication technology develops, there are many cases where various foreign words need to be expressed in Hangul. In this paper, we propose a model that recognizes and combines the consonants, medial vowels, and final consonants of a Korean syllable using a multi-label classification model, and achieves a high recognition accuracy of 98.38% as a result of learning with the public data of Korean handwritten characters, PE92. In addition, this model learned only 2,350 Hangul characters, but can recognize the characters which is not included in the 2,350 Hangul characters

현재 어깨상해는 많은 운동 참여자에게 빈번히 발생하는 질환이다. 운동 동작 시 올바르지 못한 어깨정렬로 인해 어깨의 안정성이 저해되고 그로인해 다양한 상해들이 유발되어진다. 운동 동작 시 팔꿈치와 손목간의 올바른 정렬은 어깨 안정성에 중요한 요소이다. 따라서 본 논문에서는 팔꿈치보호대와 손목밴드에 센서를 부착하여 웨어러블 장비와 함께 융복합 IT기술을 기반으로 하여 팔꿈치와 손목간의 정상범위를 직관적으로 제시하여 동적 운동 상황에서의 상해를 예방하고자 한다.

Objectives : To examine Korean Medical treatment of abnormal uterine bleeding in classical texts, along with their clinical applicability. Methods : The Benglou chapters in the Donguibogam, Fuqingzhunuke, Xuezhenglun were examined in terms of diagnostic pattern and treatment. Benglou chapters of other medical texts were referenced as well. Basic Korean Medical knowledge of abnormal uterine bleeding and its clinical application were studied. Results : As abnormal uterine bleeding is generally caused by internal damage or deficiency from excessive labor, sexual activity, food, emotional stress, specific causes for each individual should be considered when approaching each case. Conclusions : Korean Medical treatment allows for a tailored approach to each pathology according to age and duration of illness, and has strength in dealing with various situations such as emergency situations, excessive bleeding, blood stagnation. As such, application of Korean Medicine in abnormal uterine bleeding is highly appropriate.

Ten cutaneous masses from Djungarina hamsters (Phodopus sungorus) were diagnosed as nine atypical fibromas and one fibrosarcoma derived from cutaneous ganglion cell-like cells. Among these patients, nine were male and one was female. Histologically, these abnormal masses were composed of spindle-shaped or polygonal neoplastic 'ganglion cell-like' cells with abundant amphophilic vacuolated cytoplasm. Immunohistochemically, these neoplastic cells were stained for vimentin, S100, and neuron-specific enolase. Out of 9 males, 3 showed positive reactions to the androgen receptor. This report provides a detailed histologic and immunohistochemical characterization of atypical fibroma, fibrosarcoma, and the tumorigenesis of ganglion cell-like cells in Djungarian hamsters.

Activity measurement of the primary circuit water of fission reactors is one method that can provide early detection of a damaged fuel assembly in the reactor core. This is an important aspect in the safe operation of the reactor and for radiation protection of staff. Radionuclides in the primary circuit water are produced by the activation of stable nuclides and the fission of fissile nuclides, mainly the isotope ²³⁵U. In the LVR-15 research reactor, measurement of the activity of the primary circuit water has been regularly undertaken since 1996. A water sample is taken from the primary circuit every week and the activities are measured four days later using gamma spectrometry. The results of these long-term measurements from 1996 to 2022 are presented. The activity time dependences of the individual radionuclides are discussed in relation to fuel assembly damage and for events connected to contamination of the water by objects inserted into the primary circuit during experiments carried out near the reactor core.
