After establishment of Banwol industrial complex in 1987, Ansan city becomes the largest industrial sector development in Gyeonggi-do, Korea. As the population and industrial activity grow over this region, toxic air pollutants, particularly POPs (Persistent Organic Pollutants) from various emission sources have been major public concerns. Air samples for POPs monitoring were collected at the industrial sites ($A_2$), residential sites ($B_1$, $B_2$), commercial site (C), and rural/remote site (D) of the area of Ansan during 2008 with a prolonged industrial sampling site $A_1$ from 2001 to 2008. All samples were analysed for 2,3,7,8 substituted-polychlorinated dibenzo-p-dioxin and dibenzofurans (PCDD/Fs) and dioxin like polychlorinatd diphenyls (dl-PCBs). In site $A_1$, a steady decline of their concentrations from 2003 to 2008 was observed due to the reinforced emission guideline from waste incinerators. The average concentration of the PCDD/Fs and dl-PCBs ranged between 0.118 pg-TEQ/$m^3$ (rural/remote site D) and 0.532 pg-TEQ/$m^3$ (industrial area $A_2$). These level were generally consistent with previous studies in Gyeonggi-do, while higher than other places. Most of PCDD/Fs congener were partitioned into particle phase, whereas dl-PCBs were partitioned into gas phase. The logarithm of gas-particle partition coefficient $K_P$ of dl-PCBs and PCDD/Fs were well correlated with sub-cooled liquid vapor pressure $P_L$. The slope $m_T$ of log $K_P$ versus log $P_L$ for PCDD/Fs (-1.22) and dl-PCBs (-1.02) in industrial area ($A_2$) were high compared to other residential/commercial area. It suggests that this area was likely influenced by the direct emission source of PCDD/Fs and dl-PCBs. To simulate the partition of PCDD/Fs and dl-PCBs between gas and particle phase, Junge-Pankow model ($P_L$-base) and $K_{oa}$ model were applied. It was found that J-P model was more suitable than the $K_{oa}$ model in this study.

This study is aimed to report two cases of chronic kidney disease treated with Korean traditional medicine. We treated the patients with traditional herbal medicine and other treatments including acupuncture. We measured serum creatinine, estimated glomerular filtration rate(eGFR), blood urea nitrogen(BUN), albumin, red blood cell count(RBC), hemoglobin for several times during admission. Case 1 patient was diagnosed with right medulla infarction, bladder stone, chronic kidney disease. The symptoms were quadriplegia, right side dysesthesia, drowsiness and edema. Case 2 patient was diagnosed with acute cerebral infarction, hypertension, chronic kidney disease. The symptoms were right side weakness, delusion, anorexia, low back pain. Case 1 patient was hospitalized for 80 days, and case 2 patient was for 31 days. Korean traditional medicine decreased serum creatinine and BUN level, improved eGFR, increased RBC and hemoglobin. The symptoms of chronic kidney disease such as edema, general body weakness and anorexia were also improved. These cases suggest that Korean traditional medicine can be effective and safe for patients with chronic kidney disease.

Dizziness is one of the most common symptoms in clinical practice. The purpose of this study was to investigate the characteristics of patients with dizziness who visited Korean medicine hospital. This study analyzed 328 patients with dizziness who visited Dunsan Korean Medicine Hospital of Dae-Jeon University from Nov. 1st, 2012 to Oct. 31st, 2014. We gathered the data of the patients based on the medical charts. The patients were divided into 4 gorups ; central dizziness group, peripheral dizziness group, presyncope dizziness group, functional dizziness group, In the distribution according to sex, the number of female patients was higher than the male patients in all the types of dizziness except the presyncope group. The average age of the central group was higher than any other types. The peripheral and central group were most frequently admitted. The average hospitalization period were categorized as follows : central group 37.31, presyncope group 17, functional group 14.21, peripheral group 13.5 days. The following numbers of patients showed the distribution of each syndrome differentiation ; deficiency of qi and blood(氣血兩虛) 58.8%, plegm-dampness syndrome(濕痰中阻) 18.0%, hyperactivity of liver yang(肝陽上亢) 14.3%, deficiency of kidney essence(腎精不足) 8.8%. The distribution of herbal medicine for dizziness were categorized as follows ; Jaeumkeonbi-tang(Ziyinjianpi-tang, 滋陰健脾湯) 50.4%, Banhabaekchulcheonma-tang(Banxiabaishutianma-tang, 半夏白朮天麻湯) 10.2% and Bojungikgi-tang(Buzhongyiqi-tang, 補中益氣湯) 4.1%. The 86.0% of patients with dizziness has improved. The peripheral showed highest rate of improvement(100%). This report would serve as a reference data for further study about patients with dizziness in the clinical field of Korean medicine.

Atmospheric concentrations of polychlorinated dibezo-p-dioxins and furans (PCDD/Fs) were investigated at urban-residential (Group I: Suwon, Guri and Goyang), industrial (Group II: Ansan, Siheung and Bucheon), urban-rural mixed (Group III: Yangju, Pocheon and Dongducheon) and rural regions (Group IV: Yangpyeong) in Gyeonggi-do from February 2012 to November 2012 quarterly. The concentrations of PCDD/Fs ranged from 0.018 to $0.109pgTEQm^{-3}$ in Group I (mean value: $0.061pgTEQm^{-3}$), 0.059 to $0.367pgTEQm^{-3}$ in Group II (mean value: $0.179pgTEQm^{-3}$), 0.072 to $0.836pgTEQm^{-3}$ in Group III (mean value: $0.334pgTEQm^{-3}$) and 0.014 to $0.066pgTEQm^{-3}$ in Group IV (mean value: $0.034pgTEQm^{-3}$), respectively. In spite of the less PCDD/F emission sources than Group II (industrial regions), the level of PCDD/Fs in urban-rural mixed area showed the highest values with high fluctuation. It's likely that the Group III was affected by fugitive emissions such like biomass burning and unregulated open burning. The mean contribution of particle phase to total PCDD/F concentration was above 83% because most of PCDD/F congeners were partitioned into particle phase. We evaluated their gas-to-particles equilibriums with the regression between the particle-gas partition coefficient, $K_P(m^3{\mu}g^{-1})$ and corresponding subcooled liquid vapor pressure ($P_L$). The logarithm-$K_P$ of PCDD/Fs was poorly correlated with $P_L$ at low ambient temperature (below $10^{\circ}C$) and the slope (m) values for log-log plots of the $K_P$ vs. $P_L$ was steeper in the Group 2 and Group 3 than residential area. It implies that the slope values were likely influenced by both the direct emission source of PCDD/Fs and ambient temperature.

In this study, succession aspects of direction structure and dancing were reviewed in Moondoong drum dance succeeded by Yong Bae Cho of Goseong Ogwangdae. Sung Rak Hong who succeeded to Moondoong drum dance before Yong Bae Cho directed only 'drum dance' mainly with Goodguri rhythm. While Sung Rak Hong succeeded, the drum of Moondoong Gwangdae became smaller, which was changed from drum before 1965, to semi-drum in 1966 and tabor in 1967 and thereafter. Yong Bae Cho succeeded to Moondoong drum dance since 1970, adding 'Moondoong dance' directing tabor at the floor together with 'drum dance' before August 1972 and directing Dutbaegi rhythm. From the first succession of Goseong Ogwangdae since the winter in 1974, obscene movements were disappeared, and the setting with Yangban and contents to sublimate resentment were added in Moondoong drum dance. These changes seemed to be affected by succession format of Tongyoung Ogwangdae Moondoong drum dance and Ok Jin Gong's idiot dance. There are succession patterns when reviewing Moondoong drum dance directed by Yong Bae Cho. In case of 'Moondoong' dance, repeated forms were succeeded including 'fixed dance'->'impromptu dance'->'jump' in center of three fixed dances. In case of 'drum dance,' repeated forms were succeeded including 'fixed dance'->'rolling tabor'->'concluding' -> 'impromptu dance'->'jump' in center of four fixed dances. In 'drum dance' by Yong Bae Cho, many parts of succeeded dance by Sung Rak Hong who was a prior successor were remained. After Yong Bae Cho's death, Jong Bok Heo summarized the dance with more completed order focusing on the structure of Moondoong drum dance succeeded by Yong Bae Cho. Since then, multiple scenes were added continuously including hobbled appearance by Jong Won Heo, happy scene eating barley and scene to catch tabor stick difficultly, by Chang Ryol Heo. Yong Bae Cho added 'Moondoong dance' to the prior works only with 'drum dance' and started adding the story with resentment. The direction structure summarized by Yong Bae Cho became the basic framework in which the following directors added the scenes very easily. Like this, Yong Bae Cho was an excellent director of Goseong Ogwangdae who inherited Moondoong drum dance from the previous generation to establish and develop to hand over the next generations.
