The purpose of this study was to investigate the status of clinical nutrition services at various medical centers in Seoul, Korea. A questionnaire was distributed to the departments of nutrition at 44 hospitals in Seoul on July 2009. Nutritional screening carried out at a rate of 59.1% at the medical centers, and a significant difference was found according to the type of center, from 100% in tertiary hospitals to 18.8% in normal hospitals. On annual average, the numbers of inpatients, inpatients for malnutritional screening, inpatients with malnutrition, and inpatients for malnutrition management were 15,169.5, 10,870.9, 2,224.8, and 1,546.2, respectively. On average the group nutrition education was done 36.1 times/year for diabetes, 8.2 times/year for cancer, and 1.9 times/year for renal disease, and the numbers of participants 423.1, 95.1, and 31.5, respectively. On average the individual nutrition education of inpatients with diabetes was done 135.4 times/year for ordered-type, and 119.3 times/year for unordered-type, 106.2 times/year for paid-type, and 148.5 times/year for unpaid-type. The mean fee for education and counseling was the highest for peritoneal dialysis (73,090.9 won) but the lowest for heart disease (23,609.1 won). On average the individual nutrition education of outpatients with diabetes was done 234.6 times/year for ordered-type, and 2.5 times/year for unordered-type, 204.4 times/year for paid-type, and 32.7 times/year for unpaid-type. The mean fee for education and counseling was also the highest for peritoneal dialysis (63,500.0 won) but the lowest for heart disease (21,336.4 won). To implement more effective clinical nutrition service, a national medical insurance imbursement policy should be urgently instituted such that diseases left as unpaid are covered by health insurance, including all nutrition-related disease.

The GLEAMS (Groundwater Loading Effects of Agricultural Management System, version 3.0) water quality model was used to predict hydrology and water quality and to evaluate the effects of soil types from a cattle-grazed pasture field of Bermuda-Rye grass rotation with poultry litter application as a fertilizer in North Alabama. The model was applied and evaluated by using four years (1999-2002) of field-measured data to compare the simulated results for the 2.71- ha Summerford watershed. $R^2$ values between observed and simulated runoff, sediment yields, TN, and TP were 0.91, 0.86, 0.95, and 0.69, respectively. EI (Efficiency Index) of these parameters were 0.86, 0.67, 0.70, and 0.48, respectively. The statistical parameters indicated that GLEAMS provided a reasonable estimation of the runoff, sediment yield, and nutrient losses at the studied watershed. The soil infiltration rates were compared with the rainfall events. Only high intensity rainfall events generated runoff from the watershed. The measured and predicted infiltration rates were higher during dry soil conditions than wet soil conditions. The ratio of runoff to precipitation was ranging from 2.2% to 8.8% with average of 4.3%. This shows that the project site had high infiltration and evapotranspiration which generated the low runoff. The ratio of runoff to precipitation according to soil types by the GLEAMS model appeared that Sa (Sequatchie fine sandy loam) soil type was higher and Wc (Waynesboro fine sandy loam, severely eroded rolling phase) soil type relatively lower than the weighted average of the soil types in the watershed. The model under-predicted runoff, sediment yields, TN, and TP in Wb (Waynesboro fine sandy loam, eroded undulating phase) and Wc soil types. General tendency of the predicted data was similar for all soil types. The model predicted the highest runoff in Sa soil type by 105% of the weighted average and the lowest runoff in Wc soil type by 87% of the weighted average

In the anchovy boat seine fishing boat, it is necessary to select other aquatic organisms other than live anchovies, which are the target species of catch. By making a rotating roller sorter using hydraulic pressure, the anchovy sorting amount was compared and the sorting accuracy of the rotary roller sorter, and the discharge speed of butter fish and jerry fish according to the number of roller revolutions were analyzed. The rotating roller sorter increases the weight of the sorted raw anchovy by 54%, 74% and 91.5% compared to the round bar fixed type, so it can reduce the required time by an average of 73.2%. As a result of converting the sorting accuracy to the weight of pure anchovies excluding the catch weight, the round bar fixed type was 89%; however, the average of the rotating roller sorter was 97.7%. Thus, the sorting accuracy of the rotary roller sorter was further improved by about 8.7%. The roller speed moved 7% at 300 rpm, 7.5% at 600 rpm, and 16% at 900 rpm, so butter fish were discharged overboard 10% faster than jelly fish on average. In addition, the average feed speed of butter fish and jelly fish is 1,400 mm/s when the roller rotation speed is 300 rpm, 1,480 mm/s at 600 rpm, and 1,850 mm/s at 900 rpm. A Φ58 mm roller rotates once it moved about 1.23 mm. In the future, a follow-up study of quantitative evaluation is needed targeting more non-target fish species of anchovy boat seine.

The acromioclavicular joint is commonly affected by traumatic and degenerative conditions. Most injuries are due to direct trauma, such as a fall on the shoulder. Although there is general agreement on treatment of type I, Ⅱ, Ⅳ, V and VI acromioclavicular injuries, the treatment of type Ⅲ injuries remains controversial. Sixty patients, ranging in age from 19 to 57 years(average, 32), were evaluated an average of 57.5 (range, 13 to 96) months after surgical reconstruction for Rockwood type Ⅲ Ⅳ, V acromioclavicular dislocation. Phemister method (47 cases), Bosworth (3 cases), Weaver and Dunn method (10 cases) were used to correct displacement. An increase of the coracoclavicular distance of the injured shoulder over the normal shoulder was average 7.1㎜ at initial, average l㎜ on postoperatively, and average 2㎜ at follow-up. Overall, 54 of 60(90%) patients achieved satisfactory results. Degree of increase of the coracoclavicular distance has no inliluence to clinical results.
