CYS-Net(Community Youth Safety Net) is a community-based system which is composed of various institutes and facilities in respective area cooperating and delivering various services to youths at risk as soon as possible. In other words, CYS-Net is an useful system to guide and care youths at risk so as that those youths can integrate into the society. Counselors deliver crisis interventions, medical and legal services, various guidance for youth activities, as well as counseling services in CYS-Net. Ever since CYS-Net service has been introduced in 2006, the width of the service is on a continual growth. It is important to grasp the present condition of the youth support centers` counselors in the cities, province(Do) and those in the cities, countries(Gun), and districts(Gu), who give CYS-Net service to youths directly, to understand the youth counseling in Korea. The questions of this study are as follows. how does the CYS-Net evaluation vary in accordance with the counselors who provide CYS-Net service, i.e. the youth support centers` counselors in the cities, province(Do) and those in the cities, countries(Gun), and districts(Gu)? The data, composed of 20 questions, were collected from counselors working at youth counseling centers nationwide. The number of observations is 554. This thesis reports frequencies, t-test, repeated measures of ANOVA. The evaluated differences of counselors between the youth support centers in the cities, province(Do) and in the cities, countries(Gun), and districts(Gu) were statistically significant. In other words, the youth support centers` counselors in the cities, countries(Gun), and districts(Gu) think more negatively than those in the cities, province(Do). The results are compatible with KYCI (2006)`s study that the youth support centers in the cities, countries(Gun), and districts(Gu) should be expanded to provide CYS-Net service properly.

Monolayer transition metal dichalcogenide (1L-TMDs) provides a convenient platform to design light emission from 2 dimensionally confined excitonic systems. Many body effects arising from strong interactions among carriers have been of considerable interest in nanoscience. The exciton-exciton annihilation (EEA) process reduces the generated excitons density and affects the performances of the opto-electronic devices. We studied multiexciton dynamics in chemically treated TMDs like MoS<sub>2</sub>, WS<sub>2</sub> and WSe<sub>2</sub> using non-linear photoluminescence (PL) spectroscopy. We also studied the many body correlations between excitons in pristine and chemically treated 1L-TMDs by excitation power dependence of PL and time resolved PL spectroscopy. We observed the decrease of the EEA rate after the chemical treatment.
