The modern pentathlon is an exercise in which people and people compete, as well as exercise without equipment, exercise using equipment, and exercise with animals, and it is an exercise that includes static and dynamic exercise. The ethical issues of modern pentathlon athletes are also related to the poor environment and economic reasons, and the athlete's ethical awareness, attitude, and spirit have a great influence on the athlete's mental environment. In this study, the direction of improvement of ethical problems, which are different as important issues in modern sports, was examined, and qualitative research methods were applied to explore the sports spirit and ethics of the modern pentathlon. Correct sports should not deviate from the intended purpose of the exercise or cause or force the athlete to suffer physical or mental pain. In sports, compensatoryism can be a direct cause of improved performance or record-breaking, but sometimes it can also cause distorted athletes. Air doping has ethical issues that can cause controversy over the health or fairness of athletes, mental and physical damage to athletes, and harm. Responsibilities and ethical issues of athletes who take prohibited substances or leaders or supervisors who neglect or encourage them should be treated as very important matters. In the sports field, the reward system that is subordinate to the athlete's or leader's performance is related to the athlete's or leader's livelihood. For a fair and just game progression, it is necessary to break away from the development of athletes who are only focused on performance. The problem of Unethical issues must be overcome by emphasizing the restoration of ethics that are reasonably recognized in ideology and logic.

This study was carried out in order to investigate the distribution and species composition of benthic polychaetous community in northern Kyeonggi Bay in September 1995. Mean density of benthic animals was 557 indiv./$m^2$. Benthic polychaetes were the most dominant faunal group, comprising 60 species with a mean density of 488 indiv./$m^2$. Benthic polychaetes were most abundant in Yumha Channel centering on Incheon Harbor, whereas relatively poor in the intertidal zones fringing Yongjong Island and Songdo area, and in the offshore main channel. The most dominant polychaete was Heteromastus filiformis (47.3% of polychaetous community), followed by Nephtys palybranchia, Tharyx sp., Sternaspis scutata and so on. Kyeonggi Bay could be divided into 4 regions from cluster analysis based on the dominant species composition: offsea/channel region, Incheon Harbor, intertidal zone of Yongjong Island, and intertidal zone of Songdo area. Highest species number and diversity index (H') were recorded at offsea/channel region, whereas highest faunal density at Incheon Harbor. Incheon Harbor was characterized by high abundance of H. filiformis. Compared with the previous studies carried out in Kyeonggi Bay, faunal density and species number have little changed for the recent 10 years. Dominant species was different between each study, but has been among opportunistic species of small-sized polychaetes belonging to capitellids, cirratulids or spionids. These results indicate that Kyeonggi Bay has been organically polluted steadily; specifically, this study reveals that Incheon Harbor has been the center of pollution and that the benthic community in the outer sea off Sihwa dike has become unstable.

In this study, 27 inorganic sunscreens and 23 sunscreens for children were collected to investigate the use and incorporation of 17 types of sunscreen agents, 13 types of preservatives, and 5 types of heavy metals. As a result, sunscreen agents were detected in the order of titanium dioxide (41 cases), zinc oxide (29 cases), bis-ethylhexyloxyphenyltriazine (10 cases), ethylhexyl salicylate (8 cases), and ethylhexylmethoxynamate (8 cases), and preservatives were detected in order of phenoxyethanol (6 cases), benzoic acid (1 case), and dihydroacetic acid(1 case). All of the identified sunscreen agents were suitable for labeling, but phenoxyethanol, a preservative component other than labeling, was detected at a concentration of 0.1%. Heavy metals such as lead, cadmium, arsenic, antimony, and nickel were not detected or were detected at various concentrations of less than 3.6 ㎍/g. All the detected UV filters, preservatives, and heavy metals were less than the allowed maximum amount stipulated by the Regulations on Cosmetic Safety Standards in Korea.

This study intended to develop the Performance Evaluation system for the modern pentathlon such as an Olympic sporting event. The performance evaluation index system for the modern pentathlon was developed by Microsoft Excel 2016 with Visual Basic for Application that it is able to be understandable for the practical field in sport. Consequently, the system for the performance evaluation index is able to be developed within the concept of performance analysis of sport such as a notational analysis of sport. And the performance indicators for the performance evaluation index were selected by the skills to make successful outcomes. Finally, the simulation with big data gathering by the developed system would be requested that systematic reviews on successful outcomes in other sporting events would be necessary.

What sports have in common is that they must use their bodies to play and lead to victory. The use of the body differs in many ways depending on the event, which part should be used as the focus. The commonality of all sports is that sports can achieve the best results by using and using parts of the body in harmony. The use of strength or muscles varies depending on the type of sport or the type of sport, so the use of the body or the results of athletic events also varies. Sports are premised on the organic use of the body, but the implications of sports can be found in that the degree of organic use does not apply equally to all sports. Sports demand organic balance and flexibility. Depending on the type of sport, you can explore which organic harmony produces more effective effects and find out which events are more beneficial to the human body. This study aimed to find out whether the organic harmony of the body actively contributes to the development of sports and a healthy mental culture. In this study, we proposed the hypothesis that the modern Pentathlon will induce the most desirable organic harmony as a global Olympic sport, and tried to verify that the hypothesis is valid and verifiable. In order to do this study, I tried to find out the organic viewpoints centered on the Miletos school, re-examine the meaning of the modern Pentathlon of games as an Olympic event, and conduct organic harmony and exploration of the modern Pentathlon of games in terms of sports.

This study aimed to investigate pesticide residues in 160 stalk and stem vegetables marketed in Northern Gyeonggi-do. The QuEChERS method using GC-MS/MS and LC-MS/MS was employed to analyze the residues of 341 pesticides in the samples. The maximum or lower than the residue limit was recorded in 75 samples (46.9%), while 4 samples (2.5%) exceeded the maximum residue limit (MRL). Thirty-nine kinds of residual pesticides were detected including fungicides (14), insecticides (22), herbicides (2), and plant growth regulator (1). Carbendazim and pendimethalin were the most frequelntly detected pesticides. Fenitrothion, procymidone, and diazinon exceeded MRL in garlic chives, and Welsh onion. This indicated that these vegetables along with water celery should be constantly monitored.

Twelve chlorophenols (CPs) were extracted by liquid phase microextraction (LPME) from the industrial waste-water and analyzed by GC/MS. To establish the optimal conditions, species of extraction solvent, sample amount, pH of sample, salting out effect, a number of sampling and plunger movement speed were investigated. As a result, the linearities of calibaration curves ranged from 0.9913 to 0.9999, while LODs and LOQs were from 0.05 to 10.0 ng/mL except 2,3,4,5-tetrachlorophenol and pentachlorophenol. Using this method, 4-chloro-3-methylphenol confirmed from waste water at the concentration of 784 ng/mL. The method can be applicable to detect chlorophenols from industrial waste-water.
