모바일 게임의 매크로(자동사냥)는 PC 온라인 게임의 게임봇과 같이 정해놓은 규칙에 의해 화면을 터치하는 프로그램으로서 안드로이드 애플리케이션과 Windows 응용프로그램 등 다양한 형태로 만들어져 사용된다. 이는 정직한 사용자에게 박탈감을 주고 흥미를 잃게 하여 게임을 떠나게 만들고 게임 수명을 단축시킨다. 비록 PC 온라인 게임에서 이러한 부정행위를 막기 위해 다양한 연구가 진행되었으나 모바일 게임은 네트워크 사용이 제한적이고 디바이스의 성능이 PC와 다르기 때문에 동일한 방법을 적용시키기 무리가 있다. 본 논문에서는 터치 이벤트 정보를 이용한 매크로 탐지 프레임워크를 제안한다. 모바일 게임에서 터치 이벤트는 게임을 진행하기 위한 필수적인 제어 명령이다. 매크로는 동일한 패턴으로 화면을 터치하기 때문에 정상적인 사용자들의 패턴과 차이가 있다. 캐쥬얼 게임이 대부분인 모바일 게임에서 터치이벤트는 짧은 시간 동안 매크로와 정상적인 사용자를 구별할 수 있는 가장 좋은 특징이다. 제안한 프레임워크를 활용하여 실제 모바일 게임에서 사용되는 매크로들을 탐지한 결과 100%의 정확도와 0%의 오탐률을 보였다.

Instroduction: The purpose of this study was to investigate safety education-related backgrounds and safety behaviors of elementary school children at a local area in Jeonbuk province. Methods: Study subjects were 308 5th and 6th graders from 6 schools located in J City and the data were collected from June 16-27, 2003. Research instrument to test safety behaviors was 4-points summated scale (Cronbach${\alpha}$= .94) composed of 54-items with three sub-categories school life safety (${\alpha}$= .88), traffic safety (${\alpha}$= .86), and daily life safety (${\alpha}$= .84), The data was analyzed by percentage, x2-test, t-test, ANOVA and Duncan test using SPSS/PC 10.0. Results: 1. Safety Education-related Characteristics: Safety education was mostly conducted during extracurricular hour as picnic (37%) and regular class (37.2%); and the instructors of safety education were school nurse (33.2%), classroom teacher (30.9%), and parents (23.4%) in order. About two third (71.0%) of the subjects have had many kinds of school event program such as essay writing, poster drawing, oratorical contest in the course of safety education According to gender, girl students was more favorable about school events as a effective safety education measure (x2=9.188, p= .010); and according to school location, nural school taught more at moming & closing session (x2=7.383, p= .025), by school nurse or classroom teacher (x2=36.574, p= .001), and had more frequent (x2=63.337, p= .001) safety education class. 2. Practice of safety behaviors: Mean scores of safety behaviors was $106.9{\pm}24.92$ out of 162 points. According gender, the scores of girl students (t=-3.296, p= .001) were significant higher than boy students. But there was not any significant difference according to school area According to safety education-related characteristics, the scores of safety behaviors was significantly higher in the group who thought that school event program was more effective on safety education (F=4.024, p= .019), and who were more interested in current safety education class (F= 10.203, p= .001) Conclusions: From the above findings, the authors concluded that school-based safety education was mainly conducted at extra-curricular and regular class, and by school nurse or classroom teacher in elementary school. Even though the mean scores of safety behaviors of elementary school children was in medium level, those. were significant higher in girl students and in rural school children. And extra-curricular activities and school event programs were suggested as more effective strategies for school-based safety education Based on the above findings, safety education class can be recommended in regular curricular basis; and various extracurricular activities and school event programs need to be developed for more effective school-based safety education. In addition, further study on gender-specific factors on safety behaviors and nationwide survey on school-based safety education should be needed.

본 연구는 관측된 단일 강우-유출사상으로부터 최적화 모형과 추계학적 기법을 결합하여 침투율 공식의 최적매개변수와 단위도를 결정하였다. 수문계측유역에서의 최적 단위도와 침투율을 결정하기 위하여 관측 유출수문곡선과 계산치의 절대오차누계를 최소화하는 모형과 절대최대오차를 최소화하는 선형계획모형을 정립하였다. 손실율의 매개변수를 섭동하기 위하여 추계학적 최적화방법 중의 하나인 Multistart 알고리즘을 채택하였다. Multistart는 분석가능영역을 효과적으로 탐사하여 Kostiakov, Philip, Horton 공식의 최적매개변수를 결정하였다. 유역평균침투능 $\Phi$지표를 적용하면 유일한 단위도의 종거가 결정되지만, Kostiakov, Philip, Horton 및 Green-Ampt공식은 매개변수의 값에 따라 단위도의 종거와 침투율은 달라진다. Green-Ampt공식의 매개변수는 시산법을 적용하여 결정하였다. 제안한 방법의 적용성을 검정하기 위하여 강우-유출 관측자료를 보유한 유역에 관하여 침투식의 매개변수와 단위도를 결정하였으며, 이전 연구자들의 결과보다는 나은 해를 구하였다.

As the hospitalized patients will be facing new stress situation due to change of his environment from home to hospital it will be very important to understand the psychological stress experienced by hospital patients not only for helping patients in the process of recovery from illness but also fulfil1ing the objective of comprehensive nursing care by understanding the needs of the patients. There is no doubt that it would be very helpful for treatment of patients as well as for improvement of nursing care if we know more about psychological needs of patients and give them adequate support to meet these needs. The study to find out the causes and degree of stress events experienced by hospitalized patients, with the objective of instituting improvement of nursing care program based on the needs of patients, was conducted during the month of September 1974 with 60 patients randomly selected from those admitted to medical and surgical wards at Yonsei Medical Center in that period The questionnaire form included 36 questions which are considered to be stress events for hospital patients, and was devide into five areas namely, such events related to 1) disease itself, 2) hospital environment, 3) nursing care and treatment, 4) communication and human relations, and 5) family and economic problems. The results of the study were as follows: 1. It was confirmed that hospitalization considered to be a stress producing factor and most patients perceived the admission to hospital as a stress factor. 2. According to the rating scale, it was found that degree of perceived stress shows a variation according to the source of stress producing event. 3. No significant differences in the mean values were observed statistically with the perceived stress levels according to demographic and other variables of patients related to hospitalization. 4. Among the questions related to disease itself, "Admission for surgery" was perceived most frequently as a stress event (97.14%) by patients. 5. With regard to the questions related to hospital environment, "death of the patient room-mate" was the most serious stress event perceived by patients (90%) and "living with hospital regulations"was considered to be less serious stress event (23.33%). 6. As for the questions related to nursing care and treatment, "limitation of freedom" was perceived as a stress factor most frequently (70.91%) by the patients and "worry for wrong treatment" turned out to be less frequent stress event (50.0%). 7. As for the questions related to communication and human relations, "difficulty to meet doctors when wanted"appeared to be the most frequent stress event by the respondents (75.86%) , followed by "no explanation about treatment or examination"(75.0%) and "no explanation about nursing care procedures"(71.66%). 8. With regard 111 tile questions related to family and economic problems, "inadequate finances for family living due to hospitalization"and "high cost of hospitalization" were the most frequent cause of stress mentioned by the patients. (80.0%). 9. As a result of application of the stepwise regression analysis, it was found that about 89% was explained by those events associated with disease itself, hospital environment and family and economic problems. By adding those events related to "nursing care and treatment" and "communication and human relation", 100% of stress associated with hospitalization was explained.

J2ME 모바일 프로그램은 모바일 기기가 보편화되면서 그 사용이 증가하고 있다. J2ME 프로그램은 자원이 제한된 모바일 환경에서 실행되므로 자원의 효율적인 사용이 매우 중요하다. J2ME 프로그램은 대부분 이벤트-구동 프로그램이여 효과적인 이벤트 관리가 자원 최적화에 않은 영향을 미치며 이벤트 관련 디버깅은 매우 어려운 부분이다. 본 연구에서는 실행 중에 실시간으로 이벤트 발생 및 처리 정보를 보여줄 수 있는 시스템을 설계 개발하였다. 이 시스템은 사용자 옵션에 따라 사용자가 관심 있는 이벤트만을 실행 중에 추적하거나 실행 후에 이벤트 관련 프로파일 정보를 제공한다.

In this paper we present compiler-based active rule system to efficiently maintain spatial integrity constraints in a heterogeneous, distributed environment. Specially, the prototype active rule system presented has been developed as a component of a whole middleware system called SDBC(Spatile DataBase Connectivity). Due to this reason, our active rule system is provided for heterogeneous ODBMSs in a distributed environment and used to define spatial integrity constraints using the active rules in E-C-A(Event-Condition-Action) type. Using this active rule system, an application programmer can free himself from a heavier burden on the integrity maintenance of application objects. In the compiler-based approach, active rules applicable to events raised by a database program are directly inserted into the program in a function type by the preprocessor, and then they are compiled with the application program source codes. One advantage of this approach is that there is no run-time overhead accompanied by monitoring all the database transitions when preprocessed program is executed. This active rule system also provides facilities to manage changed rules and dynamically interpret those rules at run-tuime.
