Traumatic flank hernia (TFH) is rare and prone to recurrence, which makes appropriate treatment challenging. No current guidelines define the optimal timing and method of repair. Meanwhile, recent advances in laparoscopic techniques are reshaping the options for the treatment of TFH. A dual approach that utilizes both laparoscopic and open methods has not previously been reported. Herein, we present the successful treatment of TFH after blunt trauma. A 46-year-old male patient underwent elective herniorrhaphy on hospital day 3, in which laparoscopic implantation of a sublay mesh and extracorporeal implantation of an onlay mesh were performed. Such techniques may be appropriate and result in feasible outcomes in hemodynamically stable patients with large TFH who are strongly suspected of having bowel herniation or concomitant intraperitoneal injuries. Larger studies are needed to assess the long-term results.

Scalar multiplication is the back-bone operation in the elliptic curve cryptosystem. Quad-and-add algorithm replaced the traditional double-and-add algorithm to compute the scalar multiplication. In this paper, we introduce the method of utilizing the point quadruple scalar operation in the elliptic curve cryptosystem. Induced expressions were applied to real cryptosystem and proven at C language level. Point quadruple operation can be utilized to fast and efficient computation in the elliptic curve cryptosystem.

Atmospheric particulate matter (A. P. M.) was collected and size-fractionated by an Andersen high-volume air sampler over 15 month period from Jan. 1985 to Feb. 1986 in Seoul. The concentration of chloride, nitrate and sulfate were extracted in an ultrasonic bath and were analyzed by ion chromatography. The annual arithmetical mean of A. P. M. was 128.54 $\mug/m^3$. The concentration of anions were 2.88 $\mug/m^3$ for chloride, 3.86$\mug/m^3$ for nitrate, and 25.44$\mug/m^3$ for sulfate. The content of A. P. M. was lowest in the particle size range 1.1 $\sim 3.3\mum$ and increased as the particle size increased or decreased. And the anions exhibited a seasonal variation in the isize distribution. The contents of anions were higher in winter than summer. Ther ratio of fine particles to the total particles defined by F/T for chloride, nitrate and sulfate. The F\ulcornerT of these anion generally decrease with increasing air temperature. This tendency was prevalent in the chloride and nitrate.

관계추출은 문장 내 두 개체 간의 의미적 관계를 추론하는 자연어분석 태스크이다. 딥러닝의 발전과 더불어 관계추출은 BERT 계열의 이해형 언어모델을 이용하였다. 그러나, ChatGPT의 혁신적인 등장과 함께, GPT계열의 생성형 언어모델에 대한 연구가 활발해졌다. 본 논문에서는 소규모의 생성형 언어모델(Kebyt5)을 이용하여 관계추출 성능개선을 위한 프롬프트 구성 및 생각의 사슬(CoT) 학습 방법을 제안한다. 실험결과 Kebyt5-large 모델에서 CoT 학습을 수행하였을 경우, Klue-RoBERTa-base 모델보다 3.05%의 성능개선이 있었다.

The purpose of this study is proving the effects of the internal customer satisfaction management on worker's job satisfaction at general hospital. In the relationship between the management and the satisfaction, the study also finds the moderating effect of the organizational support awareness and the organizational justice. For this study, it was surveyed targeting 270 employees who work in seven general hospitals in Busan. As the result, 246 questionnaires returned. All of these questionnaires were used in the final analysis. The method of analysis is descriptive statistics using SPSS VER. 18.0, correlation analysis, regression analysis, factor analysis and reliability analysis. The main results of empirical analysis were as follows: First, in the effect of the internal customer satisfaction management to worker's job satisfaction, it has positive effect to internal communication and the commission of authority and it has positive effect to worker's job satisfaction. Second, the organizational support awareness & the organizational justice have moderating effect on the relationship between the internal customer satisfaction management and worker's job satisfaction. Third, the study proves that supporting management hierarchy shows positive effects for all socio-demographic characteristics in the organizational support awareness and the organizational justice.

Objectives : This study explored ways to improve the quality of life related to oral health and the oral health of senior citizens by identifying the relevance of oral health-related quality of life issues, and satisfaction with dentures in elderly 65 years of age or older. Methods : This study surveyed 220 senior citizens who are currently using dentures and 65 years of age or older living in Busan. As a result, 200 questionnaires were returned. All of these questionnaires were used in the final analysis. The method of analysis was descriptive statistics using SPSS VER. 19.0, t-test, ANOVA, Pearson correlation coefficients, and regression analysis. Results : First, when verifying the difference in the quality of the health-related life of the oral cavity in accordance with the general characteristics, only average monthly income showed a significant difference. Second, the results of the analysis for factors that affect the quality of the health -related life of the oral cavity, fixation satisfaction, and mastication satisfaction, in that order, affected the general satisfaction of the elderly. Conclusions : Dentures satisfaction and the quality of the health-related life of the oral cavity show a high correlation and causality.

The purposes of this study are the analysis by content of satisfaction level of participants in the event for the systematic, efficient event tourism program. For this analysis, it was researched if there was any difference in satisfaction level of participants in event by demographic characteristics, participation level and content of program. The results of this analysis are as follows: There was a difference in satisfaction level by participants characteristics in the event tourism. There was the more recognition, the higher participation level. There was higher participation and satisfaction level in participational and special program than exhibitory program. This study has a limit that can"ft grasp the foreign visitors"f recognition for the event tourism in Gangnueng district. But, it is very important to analyze the voluntary participation and interest of local residents and it may be the fruit of this study to of a new program and suggestion point through the analysis of satisfaction level for the Heo-kyun & Heo_Nan_Sul_Hun Cultural Festival.

컴퓨팅 디바이스의 존재를 의식 하지 않고 원하는 서비스를 제공 받을 수 있는 유비쿼터스 환경하에서는 최소한의 HCI 또는 배제된 HCI 가 요구된다. 이러한 요구를 충족시키기 위해 효율적인 서비스를 제공하는 시스템들은 추론을 통해 사용자의 의도 파악 및 그에 따른 서비스를 제공 할 수 있으나 그것에 대한 정확한 판단은 실질적으로 달성하기 어렵다. 또 다른 접근 방법으로는 Event-Condition-Action (ECA) Rule 형태 기반으로써 명확한 Event Trigger 와 Event 발생시의 상황 조건을 기반으로 이미 기술된 서비스를 제공하는 것이다. ECA에 의한 서비스의 제공은 확률 기반의 추론을 통한 서비스 제공보다 더욱 명확한 서비스 제공의 판단이 가능하나 복잡한 환경에서 방대한 양의 발생 가능한 모든 Rule에 대한 기술은 많은 노력이 필요하거나 심지어는 그것이 불가능하다는 단점을 갖고 있다. 이에 본 논문은 이러한 문제를 해결하고자 효과적인 서비스 제공을 위한 ECA Rule 자동 생성 기법을 소개하고자 한다. 본 논고에서 제안하는 시스템은 사용자의 행동과 상황을 추적 및 저장하여 그 정보를 바탕으로XML 형태의 ECA Rule을 자동 생성하여 그를 바탕으로 동일한 조건 및 상황 발생시 이미 기술된 서비스를 제공한다. 이러한 과정은 ECA Rule 기반의 서비스 제공 운용에 있어 가장 취약점인 ECA Rule 작성에 대한 사용자의 노력을 Rule의 양에 상관없이 손쉽게 해결 할 뿐만 아니라 각 사용자 별 Rule을 생성함으로써 유비쿼터스 환경하에서의 개인화된 서비스를 효율적으로 제공할 것이다.
