Recently, one of the prevailing issues in management information system is to integrate heterogeneous distributed systems. With the progress of network technology, the scope of data management systems has expanded so that application systems for management of process flows have also been strongly supported. In this manner, SNUFlow (Seoul National University workFlow management system) is developed to control process flows. SNUFlow adopted CORBA(Common Object Request Broker Architecture), standard architecture of distributed object environment, as a basic communication and integration methodology. SNUFlow is composed of 4 major modules. Process Designer module covers with designing process with graphical interfaces. Workflow Engine module controls the entire system process flows using process definitions. Workflow Client module manages task lists via CORBA bridge with the help of Engine module. Workflow Monitor module can provide statistical data and audit the trail of each of process flows. We have obtained interoperability among distributed software operating on heterogeneous hardware platforms with various operating systems through the SNUlow system with the use of CORBA, which has been firmly established as international distributed object standard specification. It was meant to be practicable to extend the process management system as a tool to integrate various resources distributed on the network under component software environment.
Diagnosis Analysis of Patient Process Log Data
배준수 한국산업경영시스템학회 2019 한국산업경영시스템학회지 Vol.42 No.4
Nowadays, since there are so many big data available everywhere, those big data can be used to find useful information to improve design and operation by using various analysis methods such as data mining. Especially if we have event log data that has execution history data of an organization such as case_id, event_time, event (activity), performer, etc., then we can apply process mining to discover the main process model in the organization. Once we can find the main process from process mining, we can utilize it to improve current working environment. In this paper we developed a new method to find a final diagnosis of a patient, who needs several procedures (medical test and examination) to diagnose disease of the patient by using process mining approach. Some patients can be diagnosed by only one procedure, but there are certainly some patients who are very difficult to diagnose and need to take several procedures to find exact disease name. We used 2 million procedure log data and there are 397 thousands patients who took 2 and more procedures to find a final disease. These multi-procedure patients are not frequent case, but it is very critical to prevent wrong diagnosis. From those multi-procedure taken patients, 4 procedures were discovered to be a main process model in the hospital. Using this main process model, we can understand the sequence of procedures in the hospital and furthermore the relationship between diagnosis and corresponding procedures.
고분해능 토과전자현미경에 의한 자기터널접합 내 AIOx의 산화방법차이 및 열처리효과에 대한 연구

Both natural oxidation and plasma oxidation methods were employed to fabricate AlO$_x$ insulating layers which were analyzed by using high-resolution transmission electron microscopy (HRTEM). The oxidation in natural oxidation primarily occurred through the grain boundary at an early stage of oxidation and then throughout the grains at a later stage. The morphology of the naturally oxidized AlO$_x$ layer was rugged and modulated. In plasma oxidation, the oxidation did not occur through the grain boundary of Al but occurred uniformly throughout the Al layer. The morphology of the plasma-oxidized AlO$_x$ layer was flat and uniform. A ferromagnetic Co layer was partially oxidized because of preferred grain boundary oxidation. The locally oxidized Co layer was reduced and the interface was improved by thermal annealing. 자기터널접합에서 절연층의 형성은 자기적 성질의 향상 및 안정화에 매우 중요한 영향을 미친다. AlO$_x$ 절연층을 제조하는 방법으로서 자연 산화법과 플라즈마 산화법을 이용하여 고분해능 투과전자현미경을 사용한 미세조직 관찰 및 비교분석을 행하였다. 자연 산화법에서의 산화는 초기에 Al 결정립계를 통하여 주로 발생하였고 이후 Al 결정립 내부에서 추가의 산화가 진행되었다. 산화층의 형상은 굴곡이 심한 표면을 이루고 있었다. 플라즈마 산화법에서 산화는 Al 층 전체를 통해서 매우 빠르게 이루어졌고 시간이 지남에 따라 산화가 포화상태에 이름을 확인하였다. Al과 AlO$_x$ 간 계면은 비교적 평평하였다. 또한 자연 산화 후 열처리를 행하면 자기저항 등 자기적 성질이 보다 향상된다는 여러 연구 결과들이 보고되고 있는데 Co를 강자성층으로 택하여 고분해능 투과전자현미경으로 관찰한 결과 Al의 결정립계를 통해 국부적으로 산화된 Co 조직이 열처리에 의해 결정 Co로 환원됨을 확인하였다.
스포츠 라이프스킬 리더 역량 강화 프로그램의 효과: 자기 및 관찰 평가의 활용
배준수,임태희,양윤경 한국체육학회 2024 한국체육학회지 Vol.63 No.3
이 연구는 스포츠 라이프스킬 리더 역량 강화 프로그램 적용에 따른 (a) 리더의 자기 및 관찰평가 점수 변화를 살펴보고(b) 집단별 학생선수의 라이프스킬 변화를 확인하는 데 목적이 있었다. 연구 참여자는 프로그램 리더 4명(남자 2명, 여자2명), 프로그램에 참여하는 학생선수 41명(남자 19명, 여자 22명), 관찰평가자 2명(남자 1명, 여자 1명)이었다. 이때 프로그램 리더와 학생선수는 각각 6개 집단에 소속되었다. 프로그램은 90분씩 총 8회기 진행되었다. 자료는 PQA 자기평가 및 관찰평가 도구와 스포츠 라이프스킬 검사지를 이용해 수집했다. 자기평가는 매회기 종료 시점에 리더가 직접 작성하였고 관찰평가는 녹화된 영상을 통해 관찰자가 평가하여 총 세 시점의 자료로 취합했다. 학생선수는 프로그램 참여 전과 후에 자기보고식으로 평가하였다. 수집된 자료 중 리더에 대한 자기평가 및 관찰평가 자료는 평균점수를 산출하여 비교하였다. 학생선수들의 자료는 대응 t-test를 실시하고 효과 크기를 검토하였다. 그 결과, 리더의 자기 및 관찰평가 점수는 시점에 따라변화가 있었고 대부분 상승하였다. 학생선수의 라이프스킬은 6개 집단 중 5개 집단에서 유의한 변화가 나타났다. 스포츠라이프스킬 리더를 위한 역량 강화 프로그램은 그들의 라이프스킬 코칭 역량을 개선하는 데 도움을 주고, 이들과 함께 프로그램에 참여한 학생선수들의 라이프스킬 개발에도 보탬이 된다. This study aimed to examine the changes in (a) leaders' self- and observational-assessment scores and (b) life skills of student-athletes across different groups following the implementation of a capacity building program to life skill leaders. The study participants consisted of four program leaders (2 males, 2 females), 41 student-athletes (19 males, 22 females) participating in the program, and two observers (one male, one female). The program was conducted over a total of 8 sessions, with each session lasting approximately 90 minutes. Leaders and student-athletes were assigned to six groups each. Data were collected using the PQA (program quality assessment) self and observational assessment tools, along with the life skills scale for sport. Self-assessment was conducted by the leaders at the end of each session, and observational-assessment data were compiled from recorded video footage, resulting in three data points. Student-athletes completed a self-report assessment before and after program participation. Self and observational assessment data for leaders were compared by calculating mean scores. Student athlete data were analyzed using paired t-tests, and effect sizes were examined. AS a results, Self and observational assessment scores of leaders showed changes over time, with mostly increasing trends. Additionally, life skills of student-athletes showed significant changes in five out of six groups. A capacity building program for sports life skills leaders helps improve their coaching abilities in life skills and also supports the development of life skills among student-athletes who participate in the program.
