신진섭,전계석 慶熙大學校 1991 論文集 Vol.20 No.-

In this paper, an acoustic technique for inhomogeneous residual stress in externally loaded solid with the flaw has been studied. The relative frequency change, Δf/f, of the two signal reflected from the front surface and back of specimen has been obtained by measuring transit time. The residual stress has been determined by relative frequency change. In experiment, aluminum tensile specimen with the flaw has been made and loaded by Instrone. A spherical typed acoustic transducer of center frequency 5㎒ has been used for sending a longitudinal acoustic wave into a stressed specimen. It has been shown in experimental results that the transit time has largely changed around the flaw that residual stress has been largely distributed. It has been verified that the neck of specimen has been formed around the flaw when the specimen has been continuously loaded.

연구목적: 본 연구는 공황장애 환자들을 대상으로 성격요인과 방어기제 검사를 실시하였으며 우울 및 사회기능 정도를 측정하여 상관관계를 알아보았다. 방 법: 1997년 9월부터 1998년 8월까지 환자들중 공황장애로 진단된 35명을 대상으로 성격요인검사(Sixteen Personality Questionnaire 한국판) 및 방어기제검사(이화방어기제검사)를 시행하여 스텐점수(1-10)화 하였고, 우울증척도(Beck Depressive Inventory 한국판) 및 사회기능장애척도(Sheehan Disability 한국판)를 시행하였다. 결 과: 1) 개별항목 (1) 성격요인과 방어기제의 척도별 평균점수에서 정상보다 높거나(8점이상) 낮은(3점이하) 척도는 없었다. (2) 성격요인중 불안감이 높았고 자아강도, 신중성, 사변성은 낮은 점수를 보였다. (3) 방어기제중 신체화, 행동화의 점수가 높았고 유우머, 억제, 이타주의, 회피, 합리화는 낮은 점수를 보였다. (4) BDI의 평균점수는 18.25±9.97이었다. (5) SDS의 평균점수는 업무항목 4.88±3.11. 사회활동/오락활동항목 4.57±2.92였다. 2) 상관관계 (1) 성별간 비교에서 성격요인은 사변성, 죄책감을 방어기제는 허세, 부정, 수동공격, 투사를 남성 이 높게 보였다(p<0.05). (2) 연령증가는 성격요인중 낮은지능과 방어기제는 예견, 해리와 상관을 허세와 역상관을 보였다(p<0.05). (3) BDI 점수는 성격요인중 지능도, 자아강도, 도덕성, 죄책감, 통제력, 불안감등과 방어기 제중 해리, 신체화등과 유의미한 상관관계를 나타냈다(p<0.05). (4) 사회기능장애척도의 업무항목은 성격요인중 죄책감, 진보성, 불안감, 도덕성과 방어기제의 신 체화, 투사등과 유의미한 상관이 있었고, 사회/오락활동항목은 성격요인의 죄책감, 불안감과 방어기제중 허세, 투사 등과 유의미한 상관관계가 있는 것으로 나타났다(p<0.05). 3) BDI와 사회기능장애척도의 업무항목간에는 유의미한 상관관계가 있는 것으로 나타났다(p<0.05). 결 론: 공황장애 환자는 성격요인검사상 불안감이 높고 자아강도, 신중성, 사변성은 낮게 나타 났으며, 신체화 등의 신경증적 방어기제를 주로 사용하는 반면 유우머, 억제, 이타주의, 회피, 합리화의 방어기제는 적게 사용하는 것으로 나타났다. 증상의 강도와 관련이 있는 우울증상은 업무활동에 영향을 미쳐 이와 관련된 중등도의 사회기능의 장애를 초래하고 있는 것으로 보인다. Objectives : The purpose of this study was to evaluate the characteristics of personality factor and defense mechanism and relationship with depression and disability. Methods : Study subjects consisted of 35 panic disorder patients diagnosed with the criteria of DSM-Ⅳ. Data were collected through Sixteen Personality Factor Questionnaire, Ehwa Diagnostic Test of Defense Mechanism, Beck Depression Inventory and Sheehan Disability Scale. Statistics employed for the analyses were Pearson correlation and independent sample t-test. Results : In personality factors and defense mechanisms, there were no definitely abnormal range of scores. But, among personality factors, tension/anxiety factor scored high and unstableness/stableness, shyness/boldness and praxernia/atunia were in low range of score. In defense mechanism, somatization and acting-out scored high and humor, suppression, altruism, avoidance and rationalization scored low. The mean BDI score was 18.25±9.97. The mean score of SDS were 4.88±3.11 in work category and 4.57±2.92 in social/leasure category. Male patients were significantly correlated with guit-proneness and atuia in personality factor and passive-aggressiveness, projection, denial and show-off in defense mechanism, compared with female patients(p<0.05). The patients` age was correlated with low intelligence in persolity factor and dissociation and anticipation in defense mechanism. It was negatively correlated with show-off(p<0.05). The BDI score was correlated with low intelligence, superego, unstableness, self-conflict, high superego and atunia in personality factor and dissociation and somatization in defense mechanism(p<0.05). There was a significant relationship between BDI score and SDS work category(p<0.05). Conclusions: Panic disorder patients show high score of tension/anxiety factor and they frequently use neurotic defense style like somatization. The depressive symptom, which depends on symptom severity, appears to have influence on work category and to cause social disability.

조성일,신진섭,전계석 慶熙大學校 1993 論文集 Vol.22 No.-

In this paper, image-processing method has been studied to improve the resolution of the solid-interior image by the Wiener Filtering. Although ultrasonic imaging systems are an effective and powerful tools for nondestructive testing, the c-scan image techniques are limited by blurring and distortions introduced by the resolution limits of the systems. Wiener filter technique has been discussed in this paper to enhance c-scan image in two-dimensional applications. Experimental results of coin samples have shown better ultrasonic images than images without Wiener filter processing.

Jin Seob Shin(신진섭) 한국컴퓨터정보학회 2019 韓國컴퓨터情報學會論文誌 Vol.24 No.10

현재 화재의 58%정도는 전기에 의한 화재이다. 본 연구에서는 전기에 의한 화재의 요인을 분석하여 미연에 화재를 예방이 가능한 시스템에 대하여 연구하였다. 재난재해를 예방하기 위해서는 기본적으로 화재 징후를 알아내기 위한 다양한 전기에 관한 IoT 센서들이 필요하다. 이러한 센서들은 각각 발생하는 많은 상황정보들을 계속적으로 수신하고 메인시스템으로 전송한다. 이렇게 모아진 빅 데이터들은 패턴분석을 통해 재난이 발생할 수 있는 임계치를 벗어나는지 여부를 계속적으로 체크하며 데이터의 비교를 통하여 어느 부분의 문제가 있는지 여부도 체크할 수 있다. 임계치를 벗어나는 상황에는 경보신호를 알려주고 문제 있는 부분에 대한 정보도 전달한다. 이를 통해 과전류, 누설전류 등과 같은 전기적인 문제를 미연에 방지함으로써 화재를 예방할 수 있는 결과를 보여준다. About 58% of fires are electric fires. In this study, we analyzed the factors of fire caused by electricity and studied the system that can prevent fire in advance. In order to prevent disasters, basically, various electrical IoT sensors are needed to detect fire signs. Each of these sensors continuously receives a lot of situation information and sends it to the main system. The collected big data continuously checks whether the disaster is over the threshold that can cause disaster through pattern analysis, and can check whether there is any problem by comparing the data. In the event of a threshold, alarms are signaled and problems are reported. This prevents fire by preventing electrical problems such as overcurrent and leakage current.

Shin, Young Seob,Yoon, Yong sik,Lim, Seok-Byung,Yu, Chang Sik,Kim, Tae Won,Chang, Heung Moon,Park, Jin-hong,Ahn, Seung Do,Lee, Sang-Wook,Choi, Eun Kyung,Kim, Jin Cheon,Kim, Jong Hoon The Korean Society for Radiation Oncology 2016 Radiation Oncology Journal Vol.34 No.3

Purpose: To investigate whether preoperative chemoradiotherapy (PCRT) followed by local excision (LE) is feasible approach in clinical T2N0 rectal cancer patients. Materials and Methods: Patients who received PCRT and LE because of clinical T2 rectal cancer within 7 cm from anal verge between January 2006 and June 2014 were retrospectively analyzed. LE was performed in case of a good clinical response after PCRT. Patients' characteristics, treatment record, tumor recurrence, and treatment-related complications were reviewed at a median follow-up of 49 months. Results: All patients received transanal excision or transanal minimally invasive surgery. Of 34 patients, 19 patients (55.9%) presented pathologic complete response (pCR). The 3-year local recurrence-free survival and disease free-survival were 100.0% and 97.1%, respectively. There was no recurrence among the patients with pCR. Except for 1 case of grade 4 enterovesical fistula, all other late complications were mild and self-limiting. Conclusion: PCRT followed by an LE might be feasible as an alternative to total mesorectal excision in good responders with clinical T2N0 distal rectal cancer.

사람으로부터 나오는 신호는 다양하고 그 데이터의 양도 매우 많다. 이러한 신호는 누구에게나 똑같이 발생하는 것이 아니기 때문에 각각의 사람마다 발생하는 신호를 분석하면 그 사람의 건강을 분석할 수 있는 중요한 자료로서 사용되어질 수 있다. 본 시스템은 인체의 손끝은 장부와 연결되어 손끝의 정보를 활용하면 건강을 진단할 수 있다는 한의학적 진단방법을 활용하여 인체 손끝에서 나오는 맥, 온도, 저항을 반사형 포토센서로 측정하여 이를 분석하고 장부의 허실을 판단하여 건강을 진단하는 시스템이다. The signal data from human body is very various and much. Because the signals can not occur equally to everyone, so when they analyze their signals, these signals can be used to diagnosis each health sign. In this system, human fingertips are connected with the five vital organs and the six viscera, and if we use these oriental medical diagnosis we can measure the pulse, temperature, and resistant from by reflective photosensor and interpret it's true and false.
