This study was intended to develop and investigate reliability and validity of a scale that can measure linkage capability of community resources of counselors. This study prepared a preliminary question consisting of a total of 42 questions in 5 areas. Then, the content validity and facial validity were verified by the counseling experts with a first-degree qualification as a counselor in Korean Counselling Psychological Association, and a total of 20 final questions of 4 areas. The final questions were conducted on psychological counselors(N=306) to investigate reliability and validity. As a result of conducting an exploratory factor analysis, validity of the two-factor structure have been verified. And In the confirmatory factor analysis, two factors were shown to be appropriate. The two-factors were named 'The collection and utilization of information' and 'Association with the Organization of Information'. Also, the scale of final selection of questions were found to have a good degree of concurrent validity, interitem consistency and test-retest reliability. The implications of the present study is significant in that it is a measure of community resources linkage capability scale of counselors. In addition, this scale is expected to be useful in Wee Class, Wee Center, Youth Counseling Welfare Center, and other counseling sites.

Tropospheric aerosols are highly variant in time and space due to non-uniform source distribution and strong influence of meteorological conditions. Backscatter lidar measurement is useful to understand vertical distribution of aerosol. However, the backscatter lidar equation is undetermined due to its dependence on the two unknowns, extinction and backscattering coefficient. This dependence necessitates the exact value of the ratio between two parameters, that is, the lidar ratio. Also, Iidar ratio itself is useful optical parameter to understand properties of aerosols. Tropospheric aerosols were observed to understand variance of lidar ratio at Anmyeon island ($36.32^{/circ}N$, $126.19^{/circ}E$), Korea using a multi-wavelength raman lidar system developed by the Advanced Environmental Monitoring Research Center (ADEMRC), Gwangju Institute Science and Technology (GIST), Korea during measurement periods; March 15$\sim$April $16^{th}$, 2004 and May 24$\sim$ $8^{th}$ 2005. Extinction coefficient, backscattering coefficient, and lidar ratio were measured at 355 and 532 nm by the Raman method. Different types of aerosol layers were distinguished by the differences in the optical properties such as Angstrom exponent, and lidar ratio. The average value of lidar ratio during two observation periods was found to be $50.85\pm4.88$ sr at 355 nm and $52.43\pm15.15$ sr at 532 nm at 2004 and $57.94\pm10.29$ sr at 355 nm and $82.24\pm15.90$ sr at 532 nm at 2005. We conduct hysplit back-trajectory to know the pathway of airmass during the observation periods. We also calculate lidar ratio of different type of aerosol, urban, maritime, dust, continental aerosols using OPAC (Optical Properties of Aerosols and Clouds), Remote sensing of atmospheric aerosol using a multi-wavelengh lidar system with Raman channels is quite and powerful tool to characterize the optical propertises of troposheric aerosols.

The aim of this study was to investigate the physicochemical characteristics of native Korean Allium wakegi Araki samples, which were grown from seven local seed bulbs(Yesan, Muan, Anmyon-do, Deokjeok-do, Jeju-do, Yecheon, and China) to produce high quality native Korean Allium wakegi Araki. For the proximate composition of samples, moisture contents were in the range of 90.69~92.43%. The crude protein content of the Jeju-do sample was highest compared to the other samples. However, there were no significant differences in total sugar contents between samples. The seed bulb origin did not affect the hardness of the stem part, but was high for the leaves of the Yesan sample compared to the other samples. The results for anti-oxidative activity were as follows: Yesan(2.30 mg/mL) > China(2.51 mg/mL) > Muan (2.56 mg/mL) > Yecheon(2.74 mg/mL) > Jeju-do(2.85 mg/mL) > Anmyon-do(2.87 mg/mL) > Deokjeok-do(3.18 mg/mL). In terms of mineral and amino acid contents, the Yesan sample showed the highest levels, respectively, compared with the other samples. Food values such as contents of total phenolics and pyruvic acid were highest in the Jeju-do sample. These results show that the physicochemical characteristics of Allium wakegi Araki were significantly different according to different seed bulb origins.

Temporomandibular disorders (TMD) is a collective term embrassing a number of clinical problems that involve the masticatory musculature, the Temporomandibular joint and associated structures, or both. The prevalence of signs and symptoms associated with TMD can be best appreciated by examining epidemiologic studies. But domestic epidemiologic studies about sex, history, chief complaint, diagnosis were not sufficient comparing with foreign countries. The results obtained as follow. 1. The number of visiting patients were 6500 and mean age was 34.06 year (Male's mean age was 33.15, Female's 34.62). In the age of patients, there was no significant difference between sex. 2. There are most patients who were referred by dentist (80.07%). Most diagnostic group was arthrogenous TMD group and followed by myogenous TMD, soft tissue disease. 3. There was strong interaction between diagnostic groups and chief complaint. 4. There was little pain difference between right and left sides. Male mainly had pain onset under 6 month, but female had pain onset more than 6 month. 5. The number of patients who had joint sound history were 3445 (53.15%). There was no significant difference of pain onset between sex. Clicking sound was most among joint sounds which happened to patients. 6. In analyzing the parafunctional habit, male mainly had bruxism, but female had clenching habit.

South Korea established the 2050 Carbon Neutral Plan in response to the climate crisis, and to achieve this policy, it is very important to monitor domestic carbon emissions and atmospheric carbon concentration. Both CO₂ and CO are emitted from fossil fuel combustion processes, but the relative ratios depend on the combustion efficiency and the strength of local emission regulations. In this study, the relationship between CO₂ and CO was analyzed using ground observation data for the period of 2018~2020 at Anmyeon-do site and the CO/CO₂ ratio according to regional origin during high CO₂ cases was investigated based on the footprint simulated from Stochastic Time-Inverted Lagrangian Transport (STILT) model. CO₂ and CO showed a positive correlation with correlation coefficient of 0.66 (p < 0.01), and averaged footprints during high CO₂ cases confirmed that air particles mainly originated from eastern and north-eastern China, and inland of Korean Peninsula. In addition, it was revealed that among the cases of high CO₂ concentration, when the CO/CO₂ ratio is high, the industrial area of eastern China is greatly affected, and when the ratio is low, the contribution of the domestic region is relatively high. The ratio of CO₂ and CO in this study is significant in that it can be used as a useful factor in determining the possibility of domestic and foreign origins of climate pollutants.

A tattoo is a cultural form that has been handed down to mankind for a long time. Traditional tattoo customs that have been handed down and developed in the various cultures of mankind have the important value of academic research in various fields such as history, art, society, etc. The Derung people, one of the minorities living in Yunnan Province and nearby areas in the southwest of China, have 'facial tattoo' customs. The traditional culture of the Derung people, which had maintained the form of primitive society until 1949 when the People's Republic of China was established, was passed down through oral tradition, so there are no preserved materials about their tattoo culture, showing the need for research on the culture. Therefore, it was conducted in two ways: a research on modern and contemporary literature and a field trip to Yunnan Province. The exact reason and time of facial tattoo customs are unknown, but the customs disappeared after being banned in 1966 due to the Chinese Cultural Revolution. The symbols and functions of facial tattoos can be largely divided into four categories, including religious worship, coming-of-age ceremonies, aesthetic decorations, and ethnic and social history, through an on-site survey and research by modern and contemporary scholars. And, it is known that women of the Derung People get tattoos from the age of 7 to 8. The design of facial tattoos became more complicated for upper-class women and simpler for lower-class women depending on the area they live. Tattoos are mainly performed by relatives, and mainly bamboo skewers and lixivium extracted from the bottom of the pot are used as the materials. Currently, there are fewer than 25 women of the Derung people with facial tattoos, and most of them are elderly. Therefore, they seem to disappear altogether within a few decades. Therefore, it is urgent to have documentation on the unique facial tattoo culture of the Derung people.

Precipitation samples were collected at Anmyeon (1997 - 2004), Uljin, and Gosan (1998 ~ 2004), the background area of the Korean Peninsula. These samples were analyzed for the concentration of 9 major ionic components ($F^{-}$,$Cl^{-}$, $NO_{3}^{-}$, $SO_{4}^{2-}$, $Na^{+}$, $NH_{4}^{+}$, $K^{+}$, $Mg^{2+}$, $Ca^{2+}$) with including a pH and an electric conductivity. Data quality for these samples was verified by ion balance and conductivity balance which are based on GAW manual for precipitation chemistry and the number of valid data at Anmyeon, Uljin, and Gosan is 249, 173, and 188, respectively. During the study period, the precipitation-weighted average pH at Anmyeon, Uljin, and Gosan was found to be 4.81, 4.87 and 4.89, respectively and each annual average pH was showed below pH 5.6 for every site. From the frequency survey on the precipitation acidity, the occurrence rate of acid rain below pH 5.6 is greater than $80\%$ for every site. Particularly, the highest occurrence rate for strong acid rain below pH 4.5 was found at Anmyeon, $32.1\%$, compared with other sites ($10.4\%$ at Uljin, $15.4\%$ at Gosan). That's because acidifying species (nss-$SO_{4}^{2-}$, $NO_{3}^{-}$) are remarkably high concentration at Anmyeon.
