The purpose of this study is to identify the needs of the nursery director, teachers, parents, and the general public regarding the use of mandatory CCTV. In other words, we will examine the benefits, problems, and solutions of mandatory CCTV. The subjects of this study included families, private day care centers, private presbytery, kindergartens, teachers, parents and the general public in D metropolitan city. The research tools were modified and supplemented questionnaires appropriately for the study purpose with reference to the previous research. Collected data was analyzed by frequency and F-test using SPSS 21.0 program. The main results of this study are as follows: First, the benefits of mandatory CCTV for daycare centers is that CCTV becomes objective evidence of human rights incidents, identifies violence among children, and can take measures. In addition, mandatory CCTV can also reduce or prevent abuse. Second, major problems concerning the mandatory use of nursery school CCTV include privacy, violation of basic rights, and education. CCTV is a stressful factor that causes teachers to feel embarrassed, uncomfortable, and tense. Third, the main improvement measures for the nursery school CCTV mandate are to prevent unfair staff and complement existing guidelines for CCTV use. Based on the results of the study, we detail the benefits, problems, and solutions for the nursing home CCTV mandatory poli.

This study was conducted with the goal to identify the degree to which elementary school students' knowledge about personal information protection practices impacted their actual behavior with regard to privacy protection. To fulfill this goal, knowledge about personal information protection was set as (1) knowledge about concepts of personal information, (2) knowledge of the rights of information holders, (3) knowledge about the code of conduct for information protection, and (4) awareness of the value of personal information. As for students' behaviors to ensure their personal information protection those were set as their habits to comply with the personal in-formation protection code of conduct and their efforts to respond and recover from any personal information violation. This study was conducted targeting 510 elementary students. The degree of the students' knowledge and their behaviors was measured by first distributing a self-report survey to the students and then analyzing their responses. The results of the analysis revealed the following: First, it was found that there are no differences among the four factors of knowledge and behavior according to the status of their education. Second, the two factors that primarily affected their personal information protection behavior were found to be their awareness of the information protection code of conduct and awareness of the value of personal information. This study holds significance in that it makes suggestions as to how personal protection practices should be taught to public school students.

In a wide range of ML applications, the training data contains privacy-sensitive information that should be kept secure. Training the ML systems by privacy-sensitive data makes the ML model inherent to the data. As the structure of the model has been fine-tuned by training data, the model can be abused for accessing the data by the estimation in a reverse process called model inversion attack (MIA). Although, MIA has been applied to shallow neural network models of recognizers in literature and its threat in privacy violation has been approved, in the case of a deep learning (DL) model, its efficiency was under question. It was due to the complexity of a DL model structure, big number of DL model parameters, the huge size of training data, big number of registered users to a DL model and thereof big number of class labels. This research work first analyses the possibility of MIA on a deep learning model of a recognition system, namely a face recognizer. Second, despite the conventional MIA under the white box scenario of having partial access to the users' non-sensitive information in addition to the model structure, the MIA is implemented on a deep face recognition system by just having the model structure and parameters but not any user information. In this aspect, it is under a semi-white box scenario or in other words a gray-box scenario. The experimental results in targeting five registered users of a CNN-based face recognition system approve the possibility of regeneration of users' face images even for a deep model by MIA under a gray box scenario. Although, for some images the evaluation recognition score is low and the generated images are not easily recognizable, but for some other images the score is high and facial features of the targeted identities are observable. The objective and subjective evaluations demonstrate that privacy cyber-attack by MIA on a deep recognition system not only is feasible but also is a serious threat with increasing alert state in the future as there is considerable potential for integration more advanced ML techniques to MIA.

Water quality data from water treatment plants in Korea during 1994-1998 were investigated to find out the characteristics of their non compliance. The number of plants surveyed were approximately 600 and the number of samples were over 30,000. Ten parameters of water quality selected in this study and their non compliance % (inside parenthesis) were as follows: Heterotrophic plate count (0.14%), Total coliforms (0.08%), $NH_3$-N (0.29%), $NO_3$-N (0.14%), THMs (0.02%), Turbidity (0.11%), Residual chlorine (5.5%), $KMnO_4$ consumption (0.04%), Hardness (0.03%), pH (0.07%). These levels of non compliance were compared to those obtained from WIDB (Water Industry Database, 1996) of American Water Works Association. This study strongly supported that small water plants (<10,000 tons/day) were more vulnerable in meeting the regulation criteria of many water quality parameters such as Heterotrophic plate count. Total coliforms, $NO_3$-N, THMs, Turbidity, Residual chlorine, $KMnO_1$ consumption, Hardness and pH. The $NH_3$-N concentration was especially high in winter and its violation was frequently found in the specific areas such as the downstream of major rivers. The average THMs concentration was surprisingly low, indicating $13{\mu}g/L$ which is 43% of US. Accordingly, these characteristics must be reflected in establishing the effective management of water quality policy of drinking water in Korea.

In November 2007, the Korean Constiutional Court held that a joint penal provision in which the individual employer is punished when his or her employee is determined to have committed a crime was unconstitutional, because the joint penal provision had no contents for the culpability of an individual employer and thus violated the constitutionally protected principle of culpability. After the Korean Constitutional Court's judgment, since December 2008 the Ministry of Justice began to change the old joint penal provision into the new revised joint penal provision. On January 2010, the old joint penal provisions of 110 laws were revised. The new revised joint penal provision adds only an additional sentence: "If a juristic person, an entity or an individual perform due care and supervision over its employee for the prevention of such a crime, it will be exempted from the punishment". But an presumption of negligence clause that is added in the new revised joint penal provision is still vacuum in concerned with supervision responsibility. Probably the new form of penal provision, that is understood to be a kind of the presumption of negligence, could let the burden of proof be changed from the public prosecutor to the accused, in other words employer-side. Especially, when joint penal provision is applied to hospital as administrative punishment, according to the hospital is a (juridical) foundation or not, the application of the joint penal provision is different and unfaithful. In my opinion, therefore, a corporation liability could be considered according to various liability of employee's business and the crime its employee committed because of an organizational failure of the corporation.

Objective : Iliac screw fixation has been used to prevent premature loosening of sacral fixation and to provide more rigid fixation of the sacropelvic unit. We describe our technique for iliac screw placement and review our experience with this technique. Methods : Thirteen consecutive patients who underwent spinopelvic fixation using iliac screws were enrolled. The indications for spinopelvic fixation included long segment fusions for spinal deformity and post-operative flat-back syndrome, symptomatic pseudoarthrosis of previous lumbosacral fusions, high-grade lumbosacral spondylolisthesis, lumbosacral tumors, and sacral fractures. Radiographic outcomes were assessed using plain radiographs, and computed tomographic scans. Clinical outcomes were assessed using the Oswestry Disability Index (ODI) and questionnaire about buttock pain. Results : The median follow-up period was 33 months (range, 13-54 months). Radiographic fusion across the lumbosacral junction was obtained in all 13 patients. The average pre- and post-operative ODI scores were 40.0 and 17.5, respectively. The questionnaire for buttock pain revealed the following : 9 patients (69%) perceived improvement; 3 patients (23%) reported no change; and 1 patient (7.6%) had aggravation of pain. Two patients complained of prominence of the iliac hardware. The complications included one violation of the greater sciatic notch and one deep wound infection. Conclusion : Iliac screw fixation is a safe and valuable technique that provides added structural support to S1 screws in long-segment spinal fusions. Iliac screw fixation is an extensive surgical procedure with potential complications, but high success rates can be achieved when it is performed systematically and in appropriately selected patients.

The living lab is a user-participatory innovation space where users can solve problems by themselves. Living Lab members are able to participate in all aspects of product development from technology conception. In this study, to prevent pedestrian accidents, auto-image sensing signal system was developed in Jeonju City, using the Living Lab method. In addition, we measured effectiveness of the auto-image sensing signal system with respect to pedestrian waiting time, pedestrian and driver signal violation, and pedestrian jaywalking. It was also compared the measures before installation, after installation and after applying Living Lab method. As a result, all of the three measures of effectiveness appeared to be more effective after Living Lab than after installation. Overall, this study is very significant in that it is the first case where the living lab is applied in transportation.

Objective: The present study suggested practical measures for successful patent registration based on a review of success and failure cases of patent application filed based on inventions obtained from physical ergonomics research. Background: The protection of intellectual property (IP) contributes to economic growth and competitiveness and facilitates innovation and creativity. IP rights are pursued on research findings for effective technology transfer and commercialization; however, a patent application can be rejected if patentability requirements such as patent eligible subject matter, utility for industrial application, novelty, or non-obviousness are not satisfied. Method: Three successful and three failed cases of patent applications based on physical ergonomics research were reviewed, critical reasons for their successes and failures were examined, and measures were proposed to avoid failures in patent registration. Results: The following measures were identified based on the patent application case review. First, abstract ideas including logical procedures and/or mathematical formulas need to include use of tangible apparatus and methods in idea realization. Second, the provision of grace period inventor disclosure exception needs to be properly followed in case an invention is disclosed before filing of patent application. Lastly, a comprehensive analysis of prior art published or publicly known anywhere in the world and a claim preparation of distinguished, non-trivial features compared to prior art solutions are needed to avoid possible violation of novelty and non-obviousness. Application: The proposed measures can help to prepare a patent application with patent eligibility.

Medical treatment has great potential for conflict. Even the best-trained doctors can commit medical malpractice that result in continuing physical or mental disabilities or even death. Medical conflicts have been increasing over years. The medical conflicts between patient and medical professionals that result from medical professionals' mistakes are often fueled by a violation on the pretext of the injuries form medical malpractice and can lead to litigation. The litigation usually cost a lot of money and time. The extension of the litigation period as well as expensive cost and lack of medical knowledge placing a great burden on patients. Alternative Dispute Resolution(ADR) is more efficient than litigation. In 1988, the medical dispute mediation system has been introduces as the Act on Remedy for Damage from Medical Accident and Medical Dispute Mediation by Korean Medical Association came into effect after 23 years of enactment efforts. Medical Dispute Mediation Act(hereinafter referred to as the "MDMA") has finally entered into force from 8 April 2012. The purpose of the MDMA is to promptly and fairly redress injuries caused by medical malpractice and create a stable environment for medical services of public health or medical professionals by providing for matters regarding the mediation and arbitration of medical disputes(MDMA ${\S}1$). In an effort to secure the fair, speedy and inexpensive resolution of every malpractice case, the Korea Medical Dispute Mediation and Arbitration Agency(hereinafter referred to as the "K-MEDI") was established. Following the MDMA, the K-MEDI shall endeavor to ensure the medical dispute mediation or arbitration proceedings are conducted in a prompt, fair, and efficient manner, and patients and medical professionals shall attend proceedings in good faith with mutual trust and understanding when they participate in medical dispute mediation or arbitration proceedings.

The purpose of this study is to investigate the possibilities of science ethics education with history of science (HOS) and to develop its teaching and learning model for secondary school students. A total of 72 cases about science ethics were extracted from 20 or more HOS books, journal articles, and newspaper articles. These cases were categorized into 8 areas, such as forgery, fabrication, violation of bioethics in testing, plagiarism and stealth, unfair allocation of credit, over slander, conjunction with ideologies, and social responsibility problems. The results of this study are as follows. First, research forgery, occurring in the process of the research, was the most frequent in HOS. Second, we developed eight teaching lesson plans for each area. Third, we proposed a teaching and learning model based on the developed lesson plans as well as related teaching and learning models in the fields of science ethics education, ethics education, and history education. Our model has five steps, 'investigating-suggesting casesclarifying problems-finding alternatives-summarizing'.
