Since humans live while feeling rich in their five senses, care must be taken not to damage their hearing in order to lead a happy life. Hearing damage suffered in a living environment is common in a partial band where a specific frequency band is first damaged. However, since the initial pain of hearing damage does not appear much, it is difficult to determine the symptoms in the early stages. In this paper, we proposed a high-speed measurement method that can easily and quickly self-measure hearing damage through a simple app. In this method, 9 pure tones compensated for gain for each voice soub-band are alternately heard in both ears, so that one's own hearing damage can be detected at high speed. When 18 tone pulses were heard for 30 seconds per person, 1 out of 12 subjects was identified as suspected of partial hearing damage. And when the test subjects were informed of the hearing determination method for the number of hearings, the participants themselves immediately determined whether their hearing was damaged. This measurement method simply judges the hearing of both ears within 30 seconds with a smart phone, so that hearing measurements that took more than 10 minutes in hospitals are relatively accurate, and it was found that hearing health can be maintained while reducing time and costs.
The academic circle of the Qing Dynasty has seen a new trend, mostly based on Han-Hak through the event of the publication of "Sagojeyo" and sought a new change in the sector of Spring Autumn-Hak as well. This study is focused on understanding and evaluation of the developmental process of especially the traditional Spring Autumn-Hak view, among some views of "Sagojeyo" by the book. "Sagojeyo" does a critical analysis of Gongyang-Hak and Gokryang-Hak and the interpretation of "Spring Autumn" made by Song-Hak scholars, and which seems a kind of preparatory step to build up a new research methodology for Spring Autumn-Hak. "Sagojeyo" emphasizes the importance of "Jwacijeon" and also points out its weaknesses and strongly demands the acceptance of strengths "Gongyangjeon" and "Gokryangjeon" have in order to compensate such demerits. Even further, it tries to evaluate Spring Autumn-Hak of the Song Dynasty objectively and reasonably as possible with no prejudice. Such analysis attitude made it possible for Spring Autumn-Hak to get a new turning point starting from the publication of "Sagojeyo". The new research methodology that comprehensively judges historical research and fidelity discourse could be one of important achievements discovered in the Han-Hak-centered academic circle in the early Qing Dynasty.
The moral corruption or the reality of absence of humanity derived from the development of science and society is very serious. Especially the moral education which should provide new breakthroughs facing such issue will be the initial concern in the educational world and the key point that judges our future. This study, as a part of efforts made for such demands of the times, is an attempt to approach the field of the present elementary education specifically by deducing the abundant meaning that the Confucianism's Chungseojidoh(忠恕之道: the principle of "Faithfulness" and "Benevolence") stands for. To build an ethical social community also means to draw voluntary moral practices into this society and this is possible with our (the moral subject) struggling the problems within but not remaining in the limitations of physical norms. Chungseojidoh as universal ethics contains a virtue ethical meaning as Jenlogy, a meaning of identity recognition and self-esteem inspiration, a meaning of social community ethics as ethics of good offices, etc. Such meanings, in particular, can be discussed more profoundly in terms of educational prevention from violence or cliquish issues in school that are largely related to education of humanity if 'applying schemes for elementary education' is seen as the center of the issue. And furthermore, they will be able to open a discussion over problems of the situation which the Korean society is in - especially the insistence, egoism or conflicts between social communities - can be answered in actuality.

The voltages mainly used in ships are 450 [V], 6.6 [kV], and 11 [kV], and an earthed system is applied to ensure the stability of the power distribution system. In general, low-voltage ships using 450 [V] apply an unearthed system, while high-voltage ships using 6.6 [kV] or 11 [kV] use a high-resistance earthed system. When an earth fault occurs in a ship's power distribution system, the voltage of the healthy phase increases to the line-to-line voltage or higher, which causes an excessive impact on the insulation of the cable. Thus, analyzing this behavior is very important. In this paper, we investigate the characteristics of the line-to-earth voltage variation according to earth faults and a recognition procedure of a faulty phase using the symmetrical coordinate method for a high-resistance earthed system and unearthed system. A mathematical model of the line-to-earth voltage was derived through the symmetric coordinate method, and the ship voltage for simulations was selected as 6.6 [kV] and 450 [V]. A MATLAB simulation proved that this method can determine the highest increase of the line-to-earth voltage, which leads by 120° on the faulty phase, and it accurately judges the faulty phase in both earthed systems.

The Moon Jae-in administration insisted on reforming the prosecution for the reform of power institutions, and also tried to control the power of the prosecution through the establishment of a high-ranking public officials criminal investigation office. Then, what is the direction of the legal prosecution reform? Above all, it is a logic to drastically reduce the power of the prosecution. How to shrink it? First, it is necessary to control or check the power of prosecution and investigation that the prosecution has. Second, the key to the reform of the prosecution is perhaps to separate personnel rights from power. In order to exclude external pressure from the prosecution's personnel rights, there must be no instruction or intervention from the attorney general. To do this, the prosecutor general must go through various personnel evaluations, such as multi-faceted evaluation. Third, the essence of the High-ranking Officials Criminal Investigations Act is to deal with crimes of prosecutors, judges, police, and members of the National Assembly. It is also the core of the institutional mechanism to cover the corruption of one's family members while holding all the right to investigate, prosecution, and warrant claims, and to check the omnipresent prosecutors who have abused their right to investigate for political purposes. Then, what is necessary for the success of the high-ranking officials criminal investigation office? Above all, We think political neutrality is very necessary. The Ministry of Airborne has a very high authority of the Director. This paper intends to examine the functions and roles of the prosecution and high-ranking officials criminal investigation offices to prevent corruption. We analyzed the contents of the prosecution and the public officials criminal investigation office, and examined the limitations and problems, and the measures to control corruption in public offices.

The 61st Korean Academy of Pediatric Dentistry congress was hosted online for the first time in 2020 due to coronavirus disease-19. The congress was operated using the ZOOM platform. The aim of this paper is to analyze and evaluate the overall satisfaction and feedbacks from congress participants via anonymous Google Forms online survey. A test meeting was previously organized before the actual congress to facilitate the smooth process and the participants overall showed high satisfaction. Members who participated in test meeting compared to those who did not, found it significantly helpful, which contributed overall higher satisfaction with the online congress. Abstracts were accepted from the current pediatric dentistry residents and the oral presentations were also held online for the first time. The presenters and the judges were overall very satisfied. In an unguaranteed situation of termination of coronavirus disease-19, the decision to conduct an online congress was a favorable option.

Recently, as the number of voice recording files submitted as court evidence increases, the number of cases claiming forgery is also increasing. If the audio recording file structure and metadata, which are objective grounds, are completely forged, it is actually impossible to detect forgery of the sophisticated audio recording file. It is extremely rare for the court to reject the file structure and metadata analysis performed with the forged audio recording file. The purpose of this study is to prove that forgery of voice recording file structure and metadata is easily possible. To this end, in this study, it was introduced that forgery detection is impossible when the 'mixed paste' function, which enables sophisticated editing based on the typification of the editing method of voice recording files, is applied. Moreover, it has been proven through experiments that forgery of file structure and metadata is possible. Therefore, a stricter standard for judging the admissibility of evidence is required when the audio recording file is adopted as digital evidence. This study will not only contribute to the standard of integrity in the adoption of digital evidence by judges, but will also contribute to the method of constructing a dataset for artificial intelligence in detecting forgery of recorded files that is expected to be developed in the future.
This study examined characteristics and judges' judgments regarding sexual violence cases against individuals with intellectual disabilities by analyzing total 716 cases of court decision. Of 716 cases, 6.0% sentenced not guilty, 53.5% imprisonment, 36.7% suspended sentence. More than half of the victims had experienced sexual assault more than one time with the tendency of repeating being higher when the accused were relatives or acquaintances to the victims. In half of the total cases, the victims were not able to specify the time of incidents. Only in 20% of the cases, there was actual compulsion but in the remaining cases, there was no clear coercion used during the crimes. There are three issues regarding court's decision of sexual assault case against individuals with intellectually disabilities; (1) credibility of victims' statement, (2) inability of resist during the crimes, and (3) whether the accused were aware of the victims's disabilities. In the judgment of credibility of statement, consistency of statement was the criterion that was used most frequently, being followed by specificity of statement, motivation for false accusation, cognitive capacity of victim, and reports of statement validity analysis in the order. The most frequently used criterion of inability to resist was the victim's statement and attitude, followed by the statement and attitude of the accused, the victim's knowledge and understanding of sexuality in the order. Regarding to the awareness of disabilities on the part of the accused, the statement and attitude of the accused was most frequently used, the victims' communicative abilities, duration of relationship, and daily life competence in the order. There were no differences in the rulings and issues according to levels of disabilities and gender. When victims were under 13 credibility of statement became more argues but the awareness of disabilities less frequently than the cases of victims who were 13 or older.

In this study, a plastic bottle recycling bin system that utilizes an infrared sensor was implemented. The proposed system consists of a recognition unit, a control unit, an alarm unit, and a driving unit. The recognition unit detects the plastic bottle, measures the distance between the plastic bottle and the infrared sensor, extracts the value of the bottle, compares the extracted value with a standard range, and then transmits the control value to the control unit if the extracted value of the bottle is outside the standard range. In this case, the result of the presence or absence of a brand label or bottle cap is transmitted to the controller. The control unit opens the entrance of the recycling bin or alerts the alarm unit according to the result value transmitted from the sensor unit. In order to implement the proposed system, the recognition unit was implemented with an infrared sensor, and the control unit was made with an Arduino IDE controller, based on the C programming language. Additionally, the recognition unit and the control unit are able to communicate using analog signals. The proposed system accurately judges the presence or absence of a brand label and bottle cap of plastic bottles according to a predetermined algorithm. It then blocks the entrance of the recycling bin when a brand label or bottle cap is still attached. As the amount of waste discharged per person is relatively high and the majority of such waste is incinerated rather than recycled, the system proposed in this study is expected to increase the recycling rate of plastic bottles.

The public survey performance review conducted by the Spatial Information Quality Management Institute is conducted at the screening rate in accordance with the regulations, and the examiner directly judges the overall trend of the submitted performance based on the extracted sample. However, the evaluation of the Ministry of Land, Infrastructure and Transport, the evaluation trustee shall be specified by random extraction (Random Collection) is specified by the sample. In this study, it analyzed the details of the actual site and analyzed through securing actual performance review data. In addition, we analyzed considerations according to various field conditions and studied ways to apply the public survey performance review sampling algorithm. Therefore, detailed sampling criteria analysis by performance reviewers is necessary. A relative comparison was made feasible by comparing the data for which the real performance evaluation was performed with the outcomes of the Python automation program. This automation program is expected to be employed as a foundation program for the automated application of public survey performance evaluation sampling in the future.
