현행 형사소송법상 체포제도에 대한 검토

양문상(Mun-Sang Yang),박광섭(Kwang-Sub Park) 충남대학교 법학연구소 2009 法學硏究 Vol.20 No.2

Though an arrest is one of the most efficient tools in search for the substantial truth, it also deprives suspects of their liberty to go where they please. Therefore, balancing the conflicting principles of the investigation of crime and protection of human rights would be a rational and practical solution. Criminal Procedure Act, valid from January 1st, 2008, proclaims the principle of a Non-Arrest. In addition, the renewed legislation has improved the problem of arrest-related provisions. Even so, as far as arresting practices are concerned, criminal investigators still prefer Urgent Arrest, which is permitted in exceptional cases, to Ordinary Arrest executed by a judge-issued Arrest Warrant. Also, there has not been a proper control by judges of the period between the time of Urgent Arrest or Immediate On-sight Arrest and the time when Warrants are issued by the Court. In brief, there still remain various problems with regard to the principle of an Arrest Warrant. One of the primary characteristic of Criminal Procedural Act is not to give the rights to seek an Arrest Warrant by police investigators. Furthermore, the power to check and control potential human rights infringements by police detectives is conferred upon Prosecutors, who have the same status of criminal investigators as police investigators. Additionally, Urgent Arrest and Immediate On-sight Arrest are also permitted as an exception along with an Ordinary Arrest by Warrant. These weak points result not only in the inefficiency of investigation, but also in the vulnerability to encroachment of suspects’ human rights. To better the situations, the right to have an independent right to decide whether to arrest a suspectneeds to be guaranteed to police investigators. In checking and controlling this legal power, the Court, not a criminal investigation institution like Prosecutor’s Office, must have the right to intervene immediately in police misbehaviors. Further, in terms of Urgent Arrest and Immediate On-sight Arrest, systematic improvements are necessary, like having more specific criteria and strengthening court’s control in arresting suspects.

Objectives: The purpose of this study was to determine the effects of dental hygienists’ grit, job satisfaction, and job commitment on dental hygiene job performance and the mediating effects of job satisfaction and job commitment on the relationship between grit. Methods: From May 25 to June 13, 2022, the researcher collected and analyzed data from 213 dental hygienists working at dental hospitals and clinics. For the data analysis, SPSS Statistics 21.0 was applied to conduct a t-test, one-way ANOVA, Pearson’s correlation analysis, and hierarchical regression analysis. Results: Grit was in charge of preventive work (scaling) (3.38±0.56, p<0.05), and the lower the stress (3.39±0.57, p<0.05), the higher the grit. Dental hygiene job performance was higher when they worked in Gwangju, Jeolla-do (3.88±0.50, p<0.01), and dental clinics (3.85±0.53, p<0.01). Job satisfaction (3.45±0.49, p<0.05) and job commitment (3.28±0.56, p<0.05) were high, as they had at least a bachelor’s degree. Less job stress was associated with higher job satisfaction (3.71±0.42, p<0.001) and job commitment (3.52±0.65, p<0.001). Job satisfaction and commitment had partial mediating effects on the relationship between dental hygienists’ grit and job performance. Conclusions: It is necessary to develop a program that helps improve grit in dental hygienists to strengthen their psychological resources, job satisfaction, and job commitment.

The ground around the portal of a tunnel is the most typical part showing the 3-dimensional mechanical behavior in the tunnel. The portal slope is constructed at the weathered soft rock-mass, and remains as a potential sliding mass. The slope failure around the tunnel portal may happen drastically and induce the great disaster; hence, for the permanent stability several special techniques are required. To solve this problem, the ground around the tunnel portal may be excavated in the arch shape to develop the arching effect in horizontal direction. With the arch-type portal slope, one can reduce considerably the excavation mass and the damage of environments. This approach has not been attempted yet due to the lack of understanding and the well-defined analyzing method, so the retaining wall type portal is more universal. The 3-dimensional finite element analyses were carried out to prove that the arch type is more advantageous in safety and cost than the right angle type. The influence of the tunnel construction sequence and the strength of the rock-mass on the slope stability was investigated by focusing on the maximum shear strain in the slope, and the yield zone at the tunnel face. 터널의 갱구부는 터널에서 3차원 거동을 가장 뚜렷하게 보이는 부분이며 대체로 풍화가 진행되어 거의 토사화되어 있는 취약한 암반에 시공됨에 따라 비탈면은 잠재적인 활동체가 되게 된다. 터널 갱구부 비탈면에서 안정에 위해되는 요인이 발생했을 경우 파괴가 급속히 진행되어 대형사고로 이어질수 있으므로 특별한 안정화 대책이 필요하여 경제적으로 큰 부담이 된다. 이를 해결하기 위한 방안으로 갱구부 비탈면을 수평 아치형으로 굴착하게 되면 굴착량이 줄어서 경제적이고 자연훼손이 줄어들며 보다 안전하고 아름다운 형상을 기대할 수 있다. 그러나 인식부족으로 인하여 이와 같은 시도는 거의 이루어지지 않고 있어서 면벽식 갱구부가 보편화 되어 있는 실정이다. 본 연구에서는 아치형 갱구부 비탈면의 이점을 알아보기 위하여 3차원 수치해석을 ㄷ형과 아치형 비탈면에 대하여 각각 수행하여 그 결과를 서로 비교하였으며 터널 굴진과 암반강성에 따른 갱구부 비탈면의 안정성은 비탈면에서 발생되는 최대전단변형율과 막장면에서 터널굴진에 따른 소성접근도를 분석하여 검토하였다.

The purpose of this study is to identify the moderating effect of price fairness perceived by customers on the structural relationship between franchise coffee shops`` brand communication (advertising and promotions) and customer satisfaction and brand loyalty. The subjects were customers of franchise coffee shops located in Daegu and Gyeongbuk. 410 questionnaires were distributed, and final 392 copies among them were used for research analysis. As a result of carrying out frequency analysis, reliability analysis, exploratory factor analysis, and covariance structure analysis (SEM: structural equation model), and χ² difference test analysis, using the SPSS 20.0 program, it was found that first, the brand communication of franchise coffee shops influenced customer satisfaction positively (Hypothesis 1). Second, it was found that customer satisfaction with the brand communication of franchise coffee shops influenced brand loyalty positively (Hypothesis 2). Third, it was found that price fairness perceived by customers had no moderating effect on the influence of franchise coffee shops`` brand communication on customer satisfaction, and thus (Hypothesis 3) was rejected. The differentiation of franchise coffee shops is not easy. However, first, this study verified the long-term management effects of franchise coffee shops`` brand communication on the formation of customers`` brand loyalty as well as its short-term management effects at the level of traditional marketing. Second, this study drew the meaningful research results that the brand communication of franchise coffee shops influences customer satisfaction positively irrespective of price fairness perceived by customers, and verified the importance of brand communication for franchise coffee shops. Therefore, this study suggests that the brand communication is the beginning and end of franchise coffee shops differentiation.

Objectives: This study aimed to verify the relations of COVID-19 infection-related knowledge, dental infection control performance, and psychosocial health of dental hygienists. Methods: From the data was analyzed through the frequency analysis, t-test, one way ANOVA, and pearson’s correlation analysis with a total of 198 dental hygienists using SPSS Statistics 21.0. Results: The correct answer rate for knowledge about COVID-19 was higher with a bachelor’s degree or higher. Thus, when the level of education was higher, the performance was also high (p<0.01). COVID-19 infection control performance was highly shown in case of high age (4.43) (p<0.05) and the married (4.42) (p<0.01). Infection control performance was high when they had an educational experience of COVID-19 infection control (4.46), and when the infection control guidebooks were equipped in their workplaces (p<0.001). Degree of psychosocial health of research subjects was shown in the order of potential stress (60.6%), high-risk stress (23.7%), and healthy (15.7%). Infection control performance was higher, the psychosocial health was healthy. Conclusions: For the response to COVID-19 infectious disease and the preparation for mutated viruses and new infectious diseases in the future, it would be necessary to establish the concrete measures for establishing the strict infection control system for dental clinics and also enhancing the psychosocial health of dental hygienists.

This study is focused on establishing influence zone caused by tunnelling in limestone site. Therefore, the numerical analysis using the FLAC2D was performed considering various locations and magnitudes of cavities. To reduce the stress concentration, the shape of cavities was designed to ellipse. This parametric study reveals that the cavities located at crown part and edge part of tunnel greatly have influenced on stability of tunnel. The effect of distance between tunnel and cavity which is larger than 1-0D (Tunnel diameter) dose not directly related to stability of tunnel, but the nearer a cavity location was, the larger displacement and stress of reinforcement occured within 0.25D. 석회암 지역에서 불규칙하게 발견되고 있는 공동의 규모와 위치를 표준화하여 터널에 미치는 영향을 수치해석적으로 접근하여 영향권을 설정하였다. 공동의 불규칙한 모서리 부분의 응력집중 문제는 해석의 한계때문에 타원형으로 모델링 되었다. 공동의 위치가 터널의 천단부와 하부 모서리에 있는 경우 가장 큰 영향을 나타났다. 굴착되는 터널크기의 공동이 1D (터널직경)정도 이격되어 있으면 안정성에는 큰 영향이 없는 것으로 나타났다. 터널과 공동의 이격거리가 0.25D (터널직경) 이내의 경우에는 변위 및 지보재에 미치는 영향이 큰 것으로 나타났다.
