Abstract- In a plasma source ion implantation, the target is successively biased by negative voltage pulses with an intrinsic finite rise time, resulting in the time-dependent sheath formation around the target. Measurement of time-dependent sheath during the pulse rise show the ion matrix sheath development which is in proportion to square root of time and pulse rise rate over plasma density but independent of the ion mass.

낭종성 부갑상선 선종과 심한 골병변을 동반한 부갑상선 기능항진증은 매우 드문 질환으로서, 저자들은 양측 고관절의 통증을 초기 주소로 내원한 환자에서 고칼슘혈증과 부갑상선 호르몬 증가, 골병변의 방사선적 소견을 통해 부갑상선 기능항진증을 진단하고, 경부 초음파와 컴퓨터 단층 촬영, 부갑상선 스캔검사 및 수술중 부갑상선 낭종액 검사 등을 통해 기능성 부갑상선 낭종의 한 종류인 낭종성 부갑상선 선종을 진단하고 수술적 제거를 통하여 정상화된 1예를 경험하였다. A cystic parathyroid adenoma is rare. A case of primary hyperparathyroidism, with the cystic formation of a parathyroid adenoma and a severe bony lesion, is reported. A 52-year-old male was admitted due to pain in both hips and for evaluation of hypercalcemia. The plasma level of the intact parathyroid hormone (iPTH) was elevated to 1424 pg/mL. Ultrasonography and the computed tomography revealed a parathyroid cyst on the left thyroid lower pole. Parathyroid scintigraphy detected a parathyroid adenoma. A radiograph showed a subperiosteal bone resorption on the phalanges, and a brown tumor (osteitis fibrosa cystica) on the femur shaft was noted. A surgical excision of the parathyroid adenoma was performed. The PTH level in the cystic fluid was increased. A histological examination confirmed a cystic parathyroid adenoma. The PTH level was normalized after the operation (J Kor SOC Endocrinol 18:214-220, 2003).

Background and Objectives: The colorectal cancer rates 4th in the total cancer prevalence in Korea. The clinical patient demographics were considered with the incidence rate of the colon and rectal cancer. The clinicopathological factors were analyzed for the 5 year survival rate. Materials Methods: Of the 282 patients who were operated from Jan. 1, 1992 to Dec. 31, 2001 and diagnosed by pathological biopsy as colo-rectal cancer, 234 patients were followed up. The age, sex, location of the cancer, TNM stage, operation method, histopathological classification, metastatic region, complications after operation and the survival rate were investigated. Results: Of the 234 patients, male and female consisted of 120 cases (51.3%) and 114 cases (46.7%), with an average age of 61.6 years. The average follow up period was 52.3 months and the peri operative mortality was 5.6%. The site of the cancer was most frequent at the rectum with 127 cases (54.3%). The patients were classified according to the TNM stages with 38 cases of stage 1 (16.2%), 98 cases of II (41.9%), 72 cases of III (30.8%) and 26 cases of IV (11.1%). The 5 year survival rate in the age group older than 50 was 63.3 % and 73.5% in the group younger than 50. In regard to the operation type, the 5 year survival rate was 65.4% for elective operation and 65.8% for emergency operation. The 5 year survival rate for well differentiated, moderately differentiated, poorly differentiated cancer, and mucinous adenocarcinoma was 73.7%, 60.2%, 58.3%, and 92.6%, respectively. The 5 year survival rate of each of the TNM stage is 81.1%, 74.8%, 57.0%, and 11.5% for Classes I, II, III, and IV, respectively. Conclusion: The clinical factors were analyzed for the 5 year survival rate with no statistical significance for the age, sex, and location of the cancer. The TNM stage and histopathological differentiation were statistically significant. The colon cancer showed better prognosis compared to the rectal cancer.

There has not been particular attention focused on the comparative benefits and risks of propofol anesthesia with inhalation anesthesia in the operations of long duration. This study was assessed the anesthetic efficacy and the speed of recovery from propofol or enflurane anesthesia in patients undergoing the long term operations. The propofol group (n=25) receiver 2.0 - 2.5mg/kg propofol intravenously for the induction of anesthesia and followed by propofol infusion(6 - 12mg/kg/h). The enflurane group (n=25) was induced as the propofol group and followed by enflurane(1-2 MAC) addministration. All patients received nitrous oxide (50%) in oxygen immediately after tracheal intubation. All anesthetic agents were stopped at the time of last stitch. The hemodynamic changes were recorded and the recovery was assessed with the time from discontinuation of all anesthetics to extubation and the indices of consciousness at early recovery(recall name, eye opening on command, raise hand on request and coughing on request). The recovery tests showed no differences between the groups. Systolic pressure after intubation in propofol group was significantly increased (p<0.05), compared with enflurane group. In propofol group, seven patients received fentanyl because of light anesthetic depth. The frequency of nausea and vomiting was similar between the groups. In conclusion, the long propofol anesthesia was not associated with faster recovery than enflurane anesthesia and propofol as an agent of anesthetic maintenance was unfavorable.

The effects of acidic aerosols have been reported to be more severe, so the recent studies were focused on identifying the characteristics of acidic aerosols, and their formation mechanisms. Therefore in this study the cyclon/annular deluder/filter pack sampling system was sued to collect and evaluate acidic aerosols in Pusan area in order to investigate the variation characteristics of the secondary inorganic pollutants(SO₄,NO₃). Forty-eight 12-hr average samples, equally divided into day/night intervals, were collected at Kwangan-dong sampling site where continuous air monitoring system was operated, from June, 1995 to November, 1995. The important conclusions obtained in this study were as followings ; The highest and lowest values of monthly averaged concentration occurred in July(12.47±3.15㎍/㎥) and september (4.00±3.15㎍/㎥) for SO₄, and in July(4.10±4.76㎍/㎥), and September(0.41±0.39㎍/㎥) for NO₃. These concentration levels were in the same range as observations in other urban areas. In order to examine the relationships between the concentrations of sulfate and nitrate, and their influencing factors, the correlation analysis was conducted. From the results of correlation analysis, the following results were obtained : 1) the value of correlation coefficient between SO₄, and SO₂showed higher in daytime(r=0.46) than in nighttime (r=0.38), and in summer season(r=0.61) than in autumn season(r=0.15) and in condition of relative humidity less than 70%(r=0.50) than in condition of relative humidity more than 70%(r=0.35). 2) Especially the SO₄concentration has the highest correlationships (r=0.94) to SO₂concentration for the data of daytime in summer. 3) The value of correlation coefficient between NO₃ and NO₂ showed higher in daytime(r=0.41) than in nighttime(r=0.74), especially showed highest value(r=0.74) for the data of nighttime in summer. 4) The NO₃concentration has the reverse correlationships to temperature, and the highest value of correlation was calculated as -0.69 for the data of daytime of autumn. From the above results about concentration characteristics and correlationships for SO₄and NO₃, the following comprehensive conclusions were obtained : 1) There were similar trends of concentration variation between SO₄and NO₃. 2) The concentration of SO₄was closely related with relative humidity but that of NO₃ was related with atmospheric temperature. 3) The formation mechanism by photochemical action and NH₄NO₃dissociation reaction were considered to have influence on the concentration variation of SO₄and NO₄.

Industrial growth and urban gravitation of the population etc. have seriously deteriorated the air quality which has adverse effect on human health and property, and the situation is more serious in industrial complex as well. Therefore, it is necessary to examine the pollutants emissions inventory to establish proper and comprehensive strategies for the reduction of pollutant levels. This study is aimed at investigating the characteristics of the pollutant emissions in the vicinity of Sinpyeung·Jangrim industrial complex in Pusan. The emission quantities of air pollutants were estimated by the grid(1㎞x1㎞), the source classification, and the time on the basis of the type and the amount per month of the fuel. The important results from this study were as followings: The average emission quantity(rate) of SO₂, TSP, NOx, CO and HC showed 1926.74 ton/yr(61.09 g/sec), 367.83 ton/yr(11.66 g/sec), 1440.64 ton/yr(45.68 g/sec), 4698.33 ton/yr(148.98 g/sec) and 447.15 ton/yr(14.18 g/sec), respectively. In case of SO₂and TSP, the emission quantities were majorly contributed by stationary source(point source and area source) whose contribution percentages were calculated as 65.8%, 30.6%. On the other hand, emission quantities of NOx, CO and HC were highly contributed by mobil source(line source) whose contribution percentages were calculated as 59.3%, 84.2% and 88.6%.

Discrete subaortic stenosis is a rare cardiac disorder especially in Orientals which occupies eight to ten percent of aortic stenosis, It occurs mainly before age of eighteen and accompanies with aortic valve abnormalities such as aortic stenosis, supravalvrlar stenosis, bicuspid valve and muscular hypertrophic subaortic stenosis, and other cardiac abnormalities such as ventricular septal defect, pulmonary stenosis and coarctation of aorta. There is no report of discrete subaortic stenosis accompanied with mitral valve prolapse. The major complications of discrete subaortic stenosis are aortic insufficiency, and subacute bacterial endocarditis. We report a case of asymptomatic nineteen-year-old male of discrete subaotic stenosis with bicuspid aortic valve and mitral valve prolapse, which is comfirmed by two-dimensional and Doppler echocardiography including transesophaigeal echocardiography.
