The prognosis for pancreatic cancer patient is very poor. Patients with locally advanced disease have a median survival time of 8 to 12 months, and patients with distant metastases have significantly worse outcomes, with a median survival time of only 3 to 6 months. Approximately 30% of patients with pancreatic cancer present with locally advanced disease defined as unresectable pancreatic cancer without evidence of distant metastatic disease. Primary treatment options in locally advanced pancreatic cancer include chemotherapy and radiotherapy. Here, we reported a patient with locally advanced pancreatic cancer who does not want further chemotherapy because of chemotherapy induced nausea and vomiting. Irreversible electroporation was performed. Irreversible electroporation was well tolerated in this case, and may be a therapeutic modality for selected patients with locally advanced pancreatic cancer.

겨울철에 동남아로 여행을 떠나다니 추위를 피할 수 있어 다행으로 생각하며 부러워하는 사람이 있었으나 사실은 그렇지 않았다. 속내의와 두툼한 외투를 입고 지내다가 평균 30$\circ$C가 넘고 습도가 높은 곳에서 지내기란 고역이었으나 세탁소 종업원들의 이상한 생각을 불러 일으켜가며 챙겨간 여름옷도 하루만 입고나가면 땀으로 흠뻑젖어 한 지역에 가면 첫날에만 입고 나가며 가장 즐겨 입은 웃옷은 간편하고 빨기좋은 나이론 남방이었으나 이런 온도차에 의한 고역은 지독하여 다시 한번 격게 되어 며칠간은 심한 몸살을 하게되었다. 1978년 새해들어 채 설 기분도 가시지 않은 1월 12일에 출국하여 제일먼저 들른곳은 홍콩대학교 의과대학 예방의학교실(Community medicine)이었다. 주임교수는 WHO의 Malaria Program과 싱가폴 대학에 있던 Dr. M.J. Colbourne으로 그날따라 토요일인 때라 그 다음 날에는 Hawaii에서 열리는 암의 역학적인 면에 관하여 회의가 있어 떠난다고 하며 무척 바쁜 눈치였다. 그곳에서 주로 하는일은 의과대학생들에 대하여 강의하며 1년에 몇명씩 대학원생도 받으나 올해는 한명도 없다고 한다. 물로 대학원생의 입학자격은 의사에 한한다. 두번째 들린 곳은 태국 방콕으로 시간을 많이 보낸곳은 Mahidol대학교 보건대학(Faculty of Public Health)이었다. 12개과에 139명의 교수진과 435명의 학생을 가진 큰 학교 이다.

This thesis is to analyse the correlations between superior's behavior and subordi nate's personal character. In order to do this study first, I set up a hypothesis. Second, I surveyed the result from the questionnaire to verify it on the basis of the data on the 442 employees who work at Ban-Wol Complex in Ansan City Third, I used the SPSS program. Based on the result of the research, the hypothesis is proved as follows: The result from superior's autonomy shows high subordinate's Self-esteem and Self-regulation, but result from strong superior's regulation shows low Self-esteem and Self-regulation.

멀티모달 감정인식을 통해 사람의 감정을 정확하게 분류하고, 사람의 감정에 어울리는 음악을 매칭하는 시스템을 설계한다. 멀티모달 감정 인식 방법으로는 IEMOCAP(Interactive Emotional Dyadic Motion Capture) 데이터셋을 활용해 감정을 분류하고, 분류된 감정의 분위기에 맞는 음악을 매칭시키는 시스템을 구축하고자 한다. 유니모달 대비 멀티모달 감정인식의 정확도를 개선한 시스템을 통해 텍스트, 음성, 표정을 포함하고 있는 동영상의 감성 분위기에 적합한 음악 매칭 시스템을 연구한다.

Pancreatic cancer has a very poor prognosis. Complete surgical resection remains the only current curative treatment. Locally advanced pancreatic cancer (LAPC) is considered as unresectable because of involvement of celiac and/or mesenteric vessels. The treatment of LAPC is a challenge. Current guidelines suggest systemic therapy. However, the majority of patients will never experience conversion to surgical resection. Thus, in these patients, ablation is an alternative therapy for local control, which causes local destruction while ideally avoiding injury to surrounding healthy tissue. Irreversible electroporation (IRE) is an energy delivery system, effective in ablating tumors by inducing irreversible membrane destruction of cells. IRE demonstrated to be safe in previous studies. However, it is not free from complications, even serious. Here, we reported two cases of the IRE in LAPC patients.

Objectives: The purpose of this study was to identify the doctor-patient relationship perceived by doctors in clinical settings and the effect of doctor-patient relationships on treatment schemes. A qualitative case study was conducted for this purpose. Methods: In-depth interviews were conducted with five oriental medicine doctors and doctors working in clinical settings using a semi-structured questionnaire. Transcription and coding were performed to analyze the data. By analyzing each case individually through within-case analysis, we attempted to find themes that emerged from the research subjects' experiences with establishing relationships with patients. Afterward, a cross-case analysis was conducted to identify the meaning of the experiences through commonalities and differences. Results: Within-case analysis confirmed the thoughts and emotions of the research participants in recognizing, defining, and participating in doctor-patient relationships while delivering treatments. Case-to-case analysis derived two themes, seven categories, and 20 meaningful units for doctor-patient relationships. Conclusions: The study found that a doctor-patient relationship regarding patient treatment could be established based on the doctor's 'professional qualifications' and 'human qualities'. In the future, it is necessary to present an educational model for relationship-based intervention techniques and personality maturity. Follow-up research should be conducted to enable the establishment of therapeutic relationships between doctors and patients.

A-49-year-old male patient with no specific medical history was admitted to the clinic because of persistent epigastric pain radiating to back for 4 months. He had multiple parenchymal tumors in body and tail of pancreas, para-spinal muscle, and mediastinum on abdomen CT image. Cytologic examination of the pancreas which was done by endoscopic ultrasound guided fine needle aspiration (EUS-FNA) showed adenocarcinoma, whereas histological examination of the para-spinal mass showed undifferentiated sarcoma. Histologic examination of the pancreatic mass was made through endoscopic ultrasound guided fine needle biopsy (EUS-FNB) for accurate diagnosis, and the histologic examination of both the pancreas and posterior mediastinal mass showed the same undifferentiated sarcoma. Therefore, we reviewed the cytopathic tissue obtained from the pancreas for the first time, and it was confirmed to be similar to histologic findings in the mediastinal mass.

Purposes: In this study, we examined the factors which silenced the organizing members and how the factors affects deprivation of employment about the organization culture, the organizational silence, and the turnover intention. Methodology: In order to research, we carry out a survey on 400 employees of small and medium hospitals. Among them, 321 questionnaires were used for actual analysis, excluding insincere respondents, non-responders or duplicate respondents. In order to verify the hypotheses in this study, we conduct the covariance Structural Equation Model(SEM). Finding: We obtained results using following hypotheses. First, ''The organization culture has an effect on the turnover intention.'' Second, ''The organization culture has an effect on the organizational silence'' Third, ''The organizational silence has a influence on the turnover intention.'' Finally, ''When the organization culture mediates the organizational silence, the adaptation relationship of the ornization effectiveness is different.'', as the key hypothesis, showed that the agreement culture, rational culture, and hierarchical culture of the organization culture type were statistically significant. The organizational silence as a parameter has the partial mediating effects(-) because it has direct and indirect effects. Practical Implications: The results of this study showed that the reason for the organizational silence of the organizing members is that the organization culture by a grade of rank is the largest and these the organizational silence affects the turnover intention.

자율 주행 로봇에서 장애물 회피 기능은 핵심적인 것이다. 포텐셜 필드는 이 분야에 가장 많이 사용되어온 방법이다. 이것은 장애물의 최근접 점을 실시간으로 계산해야 하는데 이를 위해 거리 센서 데이터 프로파일로 부터 안정적으로 장애물 영역을 분할해야 하는 어려움이 있다. 본 논문에서는 분할 없이 각 장애물의 최근접 점을 실시간으로 구할 수 있는 Active Min-Depth Filter를 제안한다. 다양한 센서 노이즈 환경에 대한 시뮬레이션을 통해 Active Min-Depth Filter의 강인성을 확인할 수 있었고 실제 이동 로봇 적용하여 성공적인 결과를 얻었다.
