Long-term variations of PM_{10} and the characteristics of local meteorology related to its concentration changes were analyzed at 4 air quality sites (Ido-dong, Yeon-dong, Donghong-dong, and Gosan) in Jeju during two different periods, such as PI (2001-2006) and PII (2007-2013), over a 13-year period. Overall, the long-term trend of PM_{10} was very slightly downward during the whole study period, while the high PM_{10} concentrations in PII were observed more frequently than those in PI. The concentration variations of PM_{10} during the study period was clarified in correlation between PM_{10} and meteorological variables, e.g. the low (high) PM_{10} concentration with large (small) precipitation or high (low) radiation and in part high PM_{10} concentrations (especially, Donghong-dong and Gosan) with strong wind speed and the westerly/northwesterly winds. This was likely to be caused by the transport effect (from the polluted regions of China) rather than the contribution of local emission sources. The PM_{10} concentrations in “Asian dust” and “Haze” weather types were higher, whereas those in “Precipitation”, “Fog”, and “Thunder and Lighting” weather types were lower. The contribution of long-range transport to the observed PM_{10} levels in the urban center (Ido-dong, Yeon-dong, and Donghong-dong), if estimated by comparison to the data of the background site (Gosan), was found to explain about 80% (on average) of its input.

This study was performed by questionnaire to investigate the recognition, preference and intake of calcium and related food behaviors of high school and college students (males 200, females 200) in the Daegu area. The daily intake was determined by a 24-hr dietary recall method. The results were summarized as follows: The recognition score of calcium of the subjects was male 10.46, female 11.54, respectively. Also the preference score of calcium source foods of the subjects was male 3.40, female 3.51. The students preferred yoghurt, ice cream, sweet potatoes and milk, in the order, but they disliked beans boiled in soysauce, sesame seeds and cheese. The frequency of calcium source foods were remarkably low. Milk products were the most preferred and eated calcium source food. A day's calcium intake was 54.1~61.1% of RDA for Koreans. The meal skipping, diet and nutrition consideration ratio of the subjects were 66.5, 13.3, 20.0% respectively. There was a significant positive correlation between the recognition and preference scores of calcium.

목적: To evaluate the cumulative recurrence rate of endometriomas after a laparoscopic endometriotic cyst enucleation in adolescents and to find the factors associated with recurrence. 방법: A multicenter retrospective cohort study was performed at 3 gynecologic surgery centers between January 2000 and December 2010. Patients surgically treated by laparoscopic enucleation of endometriotic cysts younger than 20 years old were selected. We excluded patients who had reproductive tract anomalies. Endometrioma recurrence was considered when transvaginal or transrectal sonography indicated a cystic mass with a diameter of ≥ 20 mm. 결과: In total, 105 patients were followed up for 47.3 ± 44.3 months (range, 3 - 161 months). Seventeen patients (16.2 %) experienced recurrence after the first-line surgery and 8 patients (7.6 %) underwent a second surgery. The median time to recurrence was 51.1 ± 9.1 months (SEM) (range, 8 - 111 months). The cumulative recurrence rates of endometrioma per patient at 24, 36, 60 and 96 months after the first-line surgery were 6.4 %, 10 %, 19.9 % and 30.9 %, respectively. Surgical characteristics such as the diameter of the cyst, rAFS stage, unilateral or bilateral involvement, co-existence of deep endometriosis were not associated with the recurrence in this age group. 결론: The short-term recurrence rate in adolescent after the first-line surgery is relatively low but is appears to be higher according to the follow- up duration. Long-term and strict follow up is needed who have undergone surgical treatment for endometriosis in adolescent period.
조직학적 진단된 chronic necrotizing pulmonary aspergillosis 2예

CNPA는 기존의 폐질환 및 폐절제술로 인해 국소방어기전에 저하가 있거나 비특이적 전신면역상태저하를 갖고 있는 환자들에게서 주로 발생하는 만성적인 공동성 폐질환이다. 현재까지 우리나라에서는 CNPA의 보고가 없는 상태이고, 저자들은 최근 조직학적으로 진단된 CNPA 2예를 경험하였기에 보고하는 바이다. 저자들이 경험한 CNPA 환자들은 만성알코올 중독 및 기관지확장증과 같은 기저질환과 폐절제술을 받은 병력이 있었다. Aspergillus가 폐실질을 침윤하고 있는 조직소견과 조직배양에서 Aspergillus가 검출되어 조직학적 진단이 가능하였고, amphotericin B의 정주요법 및 경구 itraconazole 투여와 폐절제술 등으로 성공적으로 치료되었다. 아직 많은 임상의들에게는 낯선 질환인 CNPA의 치료성적은 환자의 동반질환 및 CNPA 자체의 중증도, 진단과 치료 시작의 지연 등에 의해 크게 좌우되므로 만성적으로 진행하는 공동성 폐병변을 갖고 있는 환자에게서 CNPA를 감별하는 것이 중요하다. Chronic necrotizing pulmonary aspergillosis (CNPA) is a chronic cavitary form of pulmonary aspergillosis. Dozens of CNPA cases have been reported in patients with systemic immunologic dysfunction or altered local defense mechanism from preexisting pulmonary disease. Review of literatures revealed that no CNPA cases have been reported in Korea yet. We experienced two cases of CNPA proven by lung biopsy. A 53-year-old alcoholic male in poor nutritional state was admitted with generalized weakness and weight loss. Chest CT revealed a cavitary nodule surrounded with ground-glass attenuation. CT-guided fine needle aspiration and biopsy was done. The biopsy specimen demonstrated dichotomously branching septated hyphae consistent with those of Aspergillus sp. Another case was a 39-year-old man with bronchiectasis who was admitted with persistent hemoptysis. He had a past history of pulmonary tuberculosis. A parahilar lesion with intracavitary soft tissue mass was incidentally detected in high-resolution GT. Left lingular segmentectomy was done due to uncontrolled hemoptysis and CNPA was histologically diagnosed. Both patients were successfully treated with intravenous amphotericin B followed by oral itraconazole. Even though CNPA is unfamiliar to most clinicians, it should be included in differential diagnoses of chronic progressive cavitary pulmonary lesion, especially in patients with immunologic dysfunction.

The purpose of this study is to report the clinical application of Hominis Placenta Pharmacopunture for Alopecia areata. Patient was diagnosed as stress-induced Alopecia areata 1 years ago. To reduce symptom, we treated a patient 8 times using Hominis Placenta Pharmacopunture. Hominis Placenta was injected subcutaneously into the lesion of head scalp alopecia. According to photographs, the lesion had been replaced with new terminal hair and the size of the lesion had decreased. This case has shown that stress-induced Alopecia areata patient could be treated by Hominis Placenta Pharmacopunture.
