In this paper, we consider generalized 𝜂-Ricci solitons associated to the general connection on Kenmotsu manifolds. We confirm the existence of such solitons by constructing a non-trivial example, and we obtain some properties of Kenmotsu manifolds that admit the generalized 𝜂-Ricci solitons associated with the general connection.

We have examined the perception and the knowledge of science-gifted students and general students in middle school level about high technology related to the science. The subjects of the investigation were 113 gifted students belonging to the universities' science-gifted education center in Busan or Ulsan, and 159 general students belonging to 2 middle schools in Busan. The survey was conducted with questionnaires on the perceptions concerning the high technology related to the science and the knowledge of a cellular phone without an antenna, and an LED(Light Emission Diode). The results of this survey concluded that the gifted students were more interested and aware of the high technology than the general students, these results are statistically significant. It has been found that there are significant differences between the gifted students and the general students in terms of the areas they want to learn, the source of information and the preferred learning method in advanced science and technology. Also, the gifted students were recognized to be better than general students in understanding an electromagnetic wave related to a cellular phone without an antenna, and a semiconductor connection with an LED.

The purpose of present study is to applied center assess method to Military General's Promotion System. This study aim to examine assessment center method based on core competency model will be applied to Military General's Promotion System and Human Resource Management. This study propose that Military General's core competency model based on job analysis to identify competency of Army, Navy, Air Force's Generals and to identify the consequences and performances of assess center method. This study propose that assess center method applied to Military General's Promotion System have many kinds. Facilitated Simulation methods were Planning and Analysis /Oral Presentation, Presentation management Coaching, customer /Peer lnteraction. Non-facilitated Simulation methods were In-Basket game, Leaderless Group Discussion, role playing. And this study propose that Military General's assessment center method based on core competency model will be effective in Military field.

Purpose: This study investigated the relationship between allergic diseases, general anxiety disorder, and depressive symptoms among Korean adolescents. Methods: A secondary analysis was conducted on the findings of the 18th Korea Youth Risk Behavior Survey (2022). The study included 51,850 adolescents and analyzed the relationships among allergic diseases, general anxiety disorder, and depressive symptoms using complex samples logistic regression analysis. Results: Among the Korean adolescents, 12.7% experienced general anxiety disorder, while 28.7% experienced depressive symptoms. The prevalence of allergic diseases was 5.7% for asthma, 36.3% for allergic rhinitis, and 22.2% for atopic dermatitis. General anxiety disorder was associated with asthma and allergic rhinitis but not atopic dermatitis. Depressive symptoms were associated asthma, allergic rhinitis, and atopic dermatitis. Conclusion: Examining the correlation among allergic diseases, general anxiety disorder, and depressive symptoms in adolescents underscores the need for implementing suitable strategies. Moreover, when addressing general anxiety disorder and depressive symptoms in adolescents, it becomes crucial to consider the presence of allergic diseases.

In this paper, various replacement policies for the general failure model are considered. There are two types of failure in the general failure model. One is Type I failure (minor failure) which can be removed by a minimal repair and the other is Type II failure (catastrophic failure) which can be removed only by a complete repair. In this model, when the unit fails at its age t, Type I failure occurs with probability 1-p(t) and Type II failure occurs with probability p(t), $0{\leq}p(t){\leq}1$. Under the model, optimal replacement policies for the long-run average cost rate and the limiting efficiency are considered. Also taking the cost and the efficiency into consideration at the same time, the properties of the optimal policies under the Cost-Priority-Criterion and the Efficiency-Priority-Criterion are obtained.

The purpose of this study is to provide the ideal forecasting model of cadastral survey work load through the Economeatric Analysis of Time Series, Granger Causality and VAR Model Analysis, it suggested the forecasting reference materials for the total amount of cadastral survey general work load. The main result is that the derive of the environment variables which affect cadastral survey general work load and the outcome of VAR(vector auto regression) analysis materials(impulse response function and forecast error variance decomposition analysis materials), which explain the change of general work load depending on altering the environment variables. And also, For confirming the stability of time series data, we took a unit root test, ADF(Augmented Dickey-Fuller) analysis and the time series model analysis derives the best cadastral forecasting model regarding on general cadastral survey work load. And also, it showed up the various standards that are applied the statistical method of econometric analysis so it enhanced the prior aggregate system of cadastral survey work load forecasting.

In this paper, a new class of general strongly nonlinear variational-like inequalities was introduced and studied. The existence and uniqueness of solutions and a new iterative algorithm for the general strongly nonlinear variational-like inequality are established and suggested, respectively. The convergence criteria of the iterative sequence generated by the iterative algorithm are also given.

This study was conducted in an inclusion class in M Inclusion Day Care Center in Busan. Thirteen sessions of cooperation teaching were applied in the inclusion class. In this sense, the purpose of this study was to identify what kinds of change occurred in the perspectives of teachers' role on both the general education teacher and the special education teacher during cooperation teaching. The data were collected through participation observations, teachers' reflective journals, and interviews. From the results of the study, it could be suggested that various types of teaching strategies need to be introduced to both teachers from the beginning of inclusion so that the general teacher and the special education teacher could understand each others roles and tasks, share opinions and ideas about daily activities, and experience the roles of the other teacher.

Purpose. The purpose of this study was conducted to identify the elders' general quality of life and oral health-related quality of life. Method. Questionnaire survey was conducted on 241 elders' living in Pohang area from August to September 2014. The results were obtained from t-test, one-way ANOVA analysis, pearson correlation coefficients and multiple regression analysis. Results. Oral health status had significant correlations with gender, age, education, income, drink and hypertension. Oral health-related quality of life showed the highest relationships with age; oral health status and general quality of life showed the highest relationships with monthly income; and, age and education period also showed influence on general quality of life. Conclusions. Therefore, it is required to strengthen oral health improvement program and oral health education for improvement of elders' quality of life.
