This study has been conducted to determine the fatigue symptoms(MFS) and its convergence association with occupational stress(KOSS) among small scale manufacturing male workers. The self-administered questionnaires were given to 428 workers employed in 14 work places under 50 members of manufacturing industries during the period from September 1st to 15th, 2015. As a results, the level of fatigue symptoms(MFS) was positively correlated with occupational stress(KOSS). Hierarchial multiple regression analysis revealed that the factors of influence with explanatory powers of 34.1% on fatigue symptoms(MFS) included sex, BMI, subject health status, smoking, regular exercise, drinking coffee, visiting out-patient department, sense of satisfaction in job life, and occupational stress(KOSS). Above results suggested that the level of occupational stress(KOSS) is so convergence influenced by variable factors as well as sociodemographic characteristics, health related characteristics and job-related characteristics, to a greater extent, by occupational stress(KOSS).

The purpose of this study was to investigate the convergence factors affecting professional identity perceived by the emotional labor of clinical practice and self-esteem in some dental hygiene students. The questionnaire was conducted in 205 dental hygiene students from 3 university in Jeollanam-do area. The data were analyzed using SPSS 12.0. Professional identity correlated positively with self-esteem(r=0.366, p<0.01), negatively with emotional labor of clinical practice(r=-0.213, p<0.01). The convergence factors influencing professional identity were satisfaction level with majors(${\beta}=0.434$), self-esteem(${\beta}=0.236$) and emotional labor of clinical practice(${\beta}=-0.199$). The regression model explained 34.6% of professional identity. Therefore, to enhance professional identity in dental hygiene students, it is required to program development to improve satisfaction level of with majors, self-esteem and management of emotional labor of clinical practice.

In this paper, the development level of information security technology for internet of things(Iot), big data and clo ud services is analyzed, and the detail policy is proposed to be leader in area of patents and ICT standard. The conc ept of ICT convergence is defined frist, market and current state of technology for three convergence services is the n analyzed, and finally main function and security target for each technology are presented. The evaluation criteria a nd IPR are analyzed to diagnose the level of patent and standard for the technology. From the results, even though the domestic competence is inferior compared to other advanced country, the efficient policy should be presented by using our capability for the big data and cloud. Furthermore, the technology development for the IoT and cloud is ne eded in advance considering the market-technology influence effects. In addition to, M2M security framework in IoT, data security in big data and reliable networking in cloud should be developed in advance.

The purpose of this study is to estimate convergence level of digital device and service and analyze group difference of consumption behavior and problem according to digital convergence level. The research method was survey with digital business expert and 343 samples. ANOVA research method was applied. The results of research are as follows. First, the study suggests that with a self-directed consuming attitude associated with both online and offline, there are the possibility to spread social problem which has unclear boundary, the possibility of intrusion into privacy through the network flow, and the matter of the credibility of information in convergence media. Second, since digital devices are important to connect consumers to the network, consumers have anxious dependence on the devices, which causes the fatigue of information to increase rapidly.

In this paper, we propose a hybrid blind equalizer with TEA and SG (stop & Go) algorithm with switching point a 0 dB of MSE value for improvement of convergence performance, where TEA is used initially to open the eye and then SG algorithm as rapid convergence is employed. The switching point is selected at the point of 0 dB MSE level because of settling the coefficients of blind equalier. As a result of computer simulatons for 8-PAM in the non-minimum phase channel, the proposed algorithm has better convergence speed as 3,500 ~ 4,500 iterations and has better MsE about 3 ~ 6 dB than those of original TEA. Also, computational cost of proposed algorithm is reduced as 5 ~ 16% than that of original TEA. and, the proposed algorithm has better convergence than SG algorithm as 8,500 ~ 17,500 iteratins but, the MSE is similar to original SG.

Silicon antimony films are studied as resistors for uncooled microbolometers. We present the fabrication of silicon films and their alloy films using sputtering and plasma-enhanced chemical vapor deposition. The sputtered silicon antimony films show a low 1/f noise level compared to plasma-enhanced chemical vapor deposition (PECVD)-deposited amorphous silicon due to their very fine nanostructure. Material parameter K is controlled using the sputtering conditions to obtain a low 1/f noise. The calculation for specific detectivity assuming similar properties of silicon antimony and PECVD amorphous silicon shows that silicon antimony film demonstrates an outstanding value compared with PECVD Si film.

A $C^*$-convergence algorithm for finite element analysis has been proposed by Bigdeli and Kelly (1997) and elements for the first three levels applied to planar elasticity have been defined. The fourth level element for the new family is described in this paper and the rate of convergence for the $C^*$-convergence algorithm is investigated numerically. The new family adds derivatives of displacements as nodal variables and the number of nodes and elements can therefore be kept constant during refinement. A problem exists on interfaces where the derivatives are required to be discontinuous. This problem is addressed for curved boundaries and a procedure is suggested to resolve the excessive interelement continuity which occurs.

합성곱 신경망(Convolutional Neural Network) 기반 객체 탐지기의 발전으로 돈사에서 돼지 모니터링이 가능하지만, 실제 농가에서 적용하기 위해서는 탐지기의 정확도를 개선해야 하는 문제가 여전히 남아있다. 본 연구에서는 합성곱 신경망 기반 돼지 탐지기의 출력인 박스들의 신뢰도 값을 평가하고 잘못된 박스들의 신뢰도 값을 보정하는 박스 레벨 후처리 방법을 제안한다. 즉, 신뢰도 값이 가짜 돼지인지 진짜 돼지인지 애매한 경우, 박스내 전경 픽셀 정보와 인접 박스의 정보를 이용하여 신뢰도 값을 낮추거나 높이는 보정 작업을 수행한다. 그리고 실제 돈사에서 취득한 11,308장의 영상 데이터로 실험한 결과, 제안 방법은 합성곱 신경망 기반 돼지 탐지기의 에러율을 4.4%에서 1.2%로 개선하는 효과가 있음을 확인하였다.

In this study, we investigated the effects of Cr dopant on the bulk trap level and grain boundary characteristics of $Bi_2O_3$-based ZnO (ZB) using dielectric functions such as $Z^*$, $Y^*$, $M^*$, ${\varepsilon}^*$, and $tan{\delta}$. More than two bulk traps of $Zn_i$ and $V_o$ probably in different ionization states could be identified in ZBCr($ZnO-Bi_2O_3-Cr_2O_3$). The grain boundaries of ZBCr could be electrochemically divided into two types: sensitive to ambient oxygen and thus electrically active one and oxygen-insensitive and thus electrically inactive one.

As the informative society becomes intensified, the rise of the convergence security offers an alternative strategic correspondence to the technology leaks that are becoming more advanced, complex, and intelligent. In order to the convergence security to provide its efficacy, training convergence security specialists is essential. However, research on the subject has yet to be considered sufficient. Thus this research focuses on defense industry security specialists to define the duty and analze critical task as well as drawn and therefore the required academic level of the critical task was examined. These research work contributes to the competence development of convergence security specialists and further enhancement on convergence security training process of academic institutions and job training institutions.
