In this paper, we present the study of a real passenger transportation system. Passenger transportation problem aims to transport passengers from bus stops to their destinations by a fleet of vehicles while satisfying various constraints such as vehicle capacity, maximum allowable riding time in a bus, and time windows at destinations. Our problem also has special issues such as mixed loading, consideration of afternoon problem together with morning problem, and transferring passengers between vehicles. Our solution approach consists of three serial procedures: bus route generation, bus scheduling, and post optimization. Efficient heuristic algorithms were developed and implemented for the procedures. The proposed solution approach has been successfully applied to several real world problem instances and could reduce about 10% to 15% of buses.

Localized mesothelioma is a primary pleural tumor that induces hypoglycemia rarely. We experienced a case of the localized mesothelioma that induced hypoglycemia. The patient was 70 year-old man who was admitted to Severance Hospital because of general weakness and mental confusion in morning before breakfast. He was found to have low level of fasting blood sugar and C-peptide, but had normal serum insulin level. After excision of the tumor, the patient was free from symptoms of hypoglycemia, and fasting blood sugar level was returned to normal range. The most likely speculation of causing hypoglycemia by the mesothelioma was thought to be that the tumor did not secrete insulin itself but the undetectable insulin-like substance and/or antigluconeogenic substances. During the follow up, 5 months after surgical removal of tumor, the patient was in a good condition without symptoms of hypoglycemia.

In order to assess the level of atmospheric pollution and to contribute the health improve ment of residents in Pusan, the authors measured the $CO, SO_2, NO_2, TSP, Noise, Pb, Cd, Cr and V$ level at 3 place by time from Jan. 1988 to Feb. 1988. THe places were Kukje, Daehyeon, Pujeon underground commercial floor. The results were as follows; 1. The range of concentration of air pollutants (1) CO : 0.5 - 3.0 ppm (2) $SO_2$ : 0.012 - 0.360 ppm (3) $NO_2$ : 0.018 - 0.089 ppm (4) TSP : 30 - 330 $\mug/m^3$ (5) Pb : 0.219 - 3.116 $\mug/m^3$ (6) Cd : 0.000 - 0.070 $\mug/m^3$ (7) Cr : 0.378 - 4.098 $\mug/m^3$ (8) V : 0.000 - 1.010 $\mug/m^3$ (9) Noise : 47 - 77 dB(A) 2. The level of all air pollutants were higher in the afternoon or night than in the morning. 3. The mean concentration of $SO_2$ in all places exceede the ambient air quality standard of $SO_2$,.

Carbonyl compounds have been measured in downtown Seoul for September 1998 using 2-series impinger method. Average concentration (ppbv) of carbonyl compounds were 12.66$\pm$5.77 HCHO, 12.05$\pm$4.86 CH3CHO and 7.92$\pm$2.63 CH3CHCH3 These compounds were the most abundant carbonyl,. They showed maximum concentration during the daytime when photochemical activity was very strong minimum concentration were usually showed during the night and early morning. Comparison of diurnal variation of carbonyl compounds with the concentration of O3, NMHC, CO and meteorological data indicated that primary and secondary sources contributed the observed carbonyl compounds. Photochemical Formation Rate(PFR) of carbonyl compounds dur-ing the sampling periods were 61% HCHO, 85% CH3CHO, 85% CH3CHO, 71% CH3COCH3.

Piroxicam is known to be a new nonsteroidal anti-inflammatory drug which has anti-inflammatory, antiedema, antigranuloma and analgesic activities through the mechanism of inhibition of prostaglandin synthetase. Clinical survey for piroxicam was carried cut on 40 cases of rheumatoid arthritis and 30 cases of degenerative arthritis who visited University Hospital from Feb. to June, 1979. Following results could be obtained: 1) In rheumatoid and degenerative arthritis, the effect of piroxicam was significant in decrease of joint pain, shortening of duration of morning stiffness, decrease in number of swollen joints, improvement of joint stiffness, decrease of E.S.R., increase of mean grip strength and decrease of articular index. 2) Side effects, almost all in G-I troubles were encountered in 6 cases in 40 cases of rheumatoid arthritis and 4 cases in 30 cases of degenerative arthritis.

The latitude-independent Pc5 pulsations with a spectral peak at -3 mHz were observed with IMAGE and SAMNET magnetometer away, ranging from -47$^{\circ}$ to -77$^{\circ}$geomagnetic latitudes, in the morning sector (0700-1000 local time) during an interval of 30 minutes on April 29, 2001. The spectral amplitude had a local peak at -67$^{\circ}$, where a sudden phase change of -180$^{\circ}$ is found. A vortical equivalent ionospheric current structure centered at latitude between 67$^{\circ}$ and 71$^{\circ}$ was observed during the Pc5 pulsations and the rotational sense of the current vortex was reversed for one cycle of the pulsation.

This paper describes the optimization of maintenance workforce scheduling at Afam power station in Nigeria. The objective is to determine the optimum schedule to satisfy growing maintenance labour requirements with minimum cost and highest efficiency. Three alternative maintenance workforce schedules are compared. The first alternative is to continue with the traditional five-day workweek schedule currently being practiced by Afam power station maintenance line. The second alternative is to switch to a seven-day workweek schedule for the morning shift only. The third alternative is to use a seven-day workweek schedule for all three work shifts. The third alternative is chosen, as it is expected to save 11% of the maintenance labour cost.

A study on the formation of particulate nitrate$(NO_3^-)$ and gaseous nitrate$(HNO_3)$ in the atmosphere was carried out in Seoul from Oct 8 to 11 1991. To collect $NO_3^-$ and $HNO_3$ in the ambient air, dual filter pack sampler (47mm$\phi$) was used. In the dual filter pack sampler, the first filter was Teflon filter (poresize 1$\mum$) for collection of $NO_3^-$ and the second filter was Nylon filter (poresize 0.45 $\mum$) for $HNO_3$. Particulate nitrate$(NO_3^-)$ and Sulfate ions were analysed by Ion chromatography. $HNO_3$ concentration was higher in the day time $(9.93\mug/m^3)$ than the night time$(3.50\mug/m^3)$, and Particulate nitrate$(NO_3^-)$ concentration was higher in the night time and early morning$(6.21\mug/m^3)$ than the day time$(4.31\mug/m^3)$. The conversion rate of $NO_x$ to total nitrate$(NO_3^-, HNO_3)$ was 7.57%/hr in the day time and 4.79%/hr in the night time, and total average conversion rate was 5.60%/hr.

Fibromyalgia syndrome is defined as a diffuse, aching musculoskeletal pain associated with multiple and discrete predictable tender points along with stiffness. A primary form associated without any disease is uncommon compared to the secondary diffuse fibrositis. We witnessed a case of a primary fibromyalgia syndrome. A 28-year-old woman was suffering from pain on posterior neck, right shoulder, upper back, left hand and arm for two years. She also complained of morning stiffness, fatigue, and headache. We treated her with stellate ganglion block with 0.25% bupivacaine, medication that included amitriptyline, TENS and superlizer. We also recommended aerobic exercise.
