  • The purpose of this study is to find out the changes in geomorphic characteristics of a small watershed when a golf course is constructed. The research site is a set of seven small watersheds including an 18-hole golf course that were randomly selected. The size, shape, and drainage network of watersheds were measured by using planimeter, watershed eccentricity, and stream order, respectively. In addition, a 25m$\times$25m mesh was used on topographic maps and grading plans in order to obtain the slope, elevation, and aspect of the watersheds. The major results of this research, while investigating of the changes in geomorphic characteristics of watersheds when a golf course is constructed, are as follows: 1. The size of watersheds is increased in accordance to the difference in elevation between the golf course site and the small watershed. 2. The watershed eccentricities are in general similar except for a few low-valued cases. 3. The changes in the average altitude and the gradient are more drastic with their bigger original values. 4. The aspects are changed more with decreasing elevation. 5. The stream order decreases in the case of a low watershed eccentricity. 6. The surface modification has a closer relationship to the slope rather than the size of effective use area. 7. With a steeper gradient and an excessively low gradient, the height of cutting/filling is increased.

  • Background: Central lymph node metastasis(CLNM) is common in papillary thyroid microcarcinoma (PTMC). The aim of this study was to define the pathohistologic risk grading based on surgical outcomes. Materials and Methods: Statistical analysis was performed to figure out the optimal cut-off values of size in preoperative ultrasound images for defining the risk of CLNM in papillary thyroid microcarcinoma. Receiver operating characteristic curves (ROC) studies were carried out to determine the cutoff value(s) for the predictor(s). All the patients were divided into two groups according to the above size and the clinic-pathological and immunohistochemical parameters were compared to determine the significance of findings. Results: The optimal cut-off value of tumor size to predict the risk of CLNM in papillary thyroid microcarcinoma was 0.575 cm (area under the curve 0.721) according to the ROC curves. Significant differences were observed on the multifocality, extrathyroidal extension and central lymph node metastasis between two groups which were divided according to the tumor size by the cutoff values. Patients in two groups showed different positive rate and intensity of Ki67. Conclusions: The size of PTMC in ultrasound images are helpful to predict the aggressiveness of the tumors, it could be an easy predictor for PTMC prognosis and assist us to choose treatment.

  • The aim of this study was to assess whether size-rank at the juvenile stage is associated with growth performance and sex ratio in olive flounder (Paralichthys olivaceus). Juveniles (mean body weight, $8.8{\pm}0.9\;g$) were selected from two age groups, with the high size-rank group (HSRG) fish in the upper 19.3-67.3% of 104 days post-hatching (dph) age group and the low size-rank group (LSRG) fish in the lower 9.0-55.7% of 116 dph age group. Triplicate groups of 100 fish were reared over 32 weeks. A heavier final body weight was observed in the HSRG ($360{\pm}12\;g$) compared to the LSRG ($315{\pm}9\;g$, P<0.05), whereas no differences in feed intake, feeding efficiency, and mortality were seen between the experimental groups. The percentage of females was significantly higher in the HSRG (51.7%) than in the LSRG (30.8%, P<0.05). In addition, a remarkable increase in growth was recorded in females, indicating that the relative frequency of females increased with a body weight increase. The results suggest that high size-rank juvenile olive flounder have better growth performance and a higher percentage of females, because females start growing faster than males before size grading occurs.

  • 조립재료의 요소시험에서 장비에 허용되는 조립재료의 입자크기가 실제 현장에서 사용되는 입자크기에 비해 작은 경우가 종종 발생하기 때문에, 이러한 경우에는 시험에 사용되는 재료의 최대입경을 시험장치의 가용 크기까지 축소시켜 시험을 수행하게 된다. 본 연구에서는 이처럼 최대입경 크기를 축소시켜 입도를 조정했을 때, 저변형률에서의 탄성계수에 미치는 영향을 평가하기 위해 대형반복삼축압축시험을 수행하였다. 본 연구 대상재료의 시험 결과, 입도 조정된 시편들은 원입도 시편의 탄성계수를 과소평가하는 경향이 있었으며, 그 차이는 저변형률에서 더 크게 발생되었다.

  • The propose of this study is to develop the optimal sizing system of ready-to-wear f3r elementary school girls using a newly invented statistical technique. The body measurements was classified by the method that equalizes the distribution of the subjects using the probability density function, to theoretically systemize a method to determine a size range of ready-to-wear for elementary school girls between 6 to 12 years old. The statistical method were 1) The total of 11 height groups, which size interval from one another is 6 cm that is an average height gap between each age. 2) In order to determine an approximate figure (m ${\times}$ n) to establish the appropriate sizes far each height group that fit to the combinations of bust and hip girth, which based on their means and standard deviations on the probability density curve to produce the standard normal distribution. 3) m and n were aligned by 4cm -the grading increments used for patterns making- and determined the size ranges by confirming the approximate figures of m and n. 4) The representative values were determined by an area ratio calculated by dividing the area determined from the range of bust and hip girth with the representative value. Considering the characteristics of subjects' distribution, the area ratios was used. 5) Weight was calculated by seeking a growth exponent for each age and multiplying it by the number of girls that fit to each size range. As sections that show the highest weight are more likely sought by the consumers, these sections were determined as the optimal size standards. 6) This optimal sizing system consists of sizes determined by the optimal size standards and its sizes are marked with height, bust and hip girth.

  • The purpose of this study is to develop a basic sloper for pants that would be appropriate for young Korean school girls between the ages of 6 to 11 years old. Pants available in the apparel market for children do not properly correspond to the body size of the target consumer group. This research explores the characteristics of the body size of the group and also identifies problems of the conventional pants sloper that would be generally used for the production of children's apparel. Ultimately it presents a basic sloper for a possible use for manufacturing. The basic slopers for pants were collected from three different companies and were the examples used for this study. An experimental pants sloper was developed, reflecting the average body size of a nine year-old girl, which Is thought to be the master size for grading in children's wear Four different cotton prototype pants were made based on the three companies' slopers and the experimental one for evaluation of the fit and overall shape of the pants on subjects. The results revealed that the design, fit, and overall look of the experimental pants was superior to that of the opposing companies' product. After alteration of the experimental sloper, a basic pants sloper was finalized. The finalized pants sloper was determined at W/4+1cm for the front waist and W/4+2cm for the back, H/4+0.5cm for the front hip and H/4+1.5cm for the bark hip, and 73cm for its length with 15.5cm and 18cm for its front and back pants width at the bottom, respectively.

  • This study was conducted comparative analysis of juvenile brassiere and adult brassiere to identify the problems of brassieres on the market. The raw data for this study was processed by SPSS 10.1 version(statistical software) and the results of this study can be summarized as follows. 1) The result of comparative analysis of juvenile brassiere and adult brassiere pattern is that each pattern showed no difference. 2) The results of the comparative analysis of juvenile and adult brassiere pattern in wing's length and angle is that even though there are some difference between juvenile and adult in side line inclination of brassiere. there is no setting difference but size of that brassiere. 3) The result of a comparative analysis pattern and cup size measurement of juvenile brassiere and adult brassiere is that even though the adult cup girth and angle is bigger than the juvenile because adults have more protrusive and bigger volume and well developed breast, some case rather the adult's cup angle is smaller than the juvenile as brand. And as we grow up to be a woman, difference of lower breast girth and breast girth are become big while difference of upper breast girth and breast girth are become small for that reason upper cup must be lower and lower cup must be higher but there is almost no difference between adult and juvenile. 4) The result of a comparative analysis of juvenile brassiere and adult brassiere bust point of the pattern is that adult brassiere's distance between bust points 6.12cm, and juvenile's 5.6cm, there are only 0.52cm difference between two products and just 0.4cm, size grading. These results are explained that even though when grow up to be a woman the distance between two bust points become to be long and breast toward out side but brassiere size don't vary with body characteristic.

  • The purpose of this study was to analyse the body sizes of $7{\sim}12$ years elementary school girls and also to categorize KS size dimensions by the detailed information of ages and body shapes. For the study, the data of SizeKorea(2004) was analysed. Height, bust, waist, hip, the ratio of waist to height and hip to height were significant between age groups, but the ratio of bust to height was not. Therefore, the increase of bust size was resulted in growth of bust circumference, instead of bust volume. In the same height group, over 11 year girls had smaller waist, while over 12 year girls had bigger hip. For Grouping girls by ages and body shapes, the ages were divided into 2 groups, under 10 years old and 11 to 12 years old. The body shapes classified into 3 groups 'Stout-shape', 'Middle-shape', and 'slim-shape', by the ratios of bust to height and hip to height. 'Stout-shape' was significantly big at the almost sizes, but 'Middle-shape' was significantly big at only circumferences, not lengths. In addition, drop(the difference between bust and hip) and lower-drop(the difference between waist and hip) were in inverse proportion to the ratios of bust to height and hip to height. It meant the increases of bust-ratio and hip-ratio of 'Stout-shape' were resulted in overweight, rather than female matureness. The distribution of sizes over 0.5% were grouped for grading system and the subtotal percentiles of each group were calculated for industrial data. The groups which covered more than 10% of consumers were 2 to 6 and the 1 or 2 groups for 'Stout-shape' were also observed, so that children's ready-to wear companies could use them efficiently for their own consumer target.

  • Background: The prognostic factors for patients with full-thickness rotator cuff tears (RCTs) include tear size, muscle atrophy and fatty infiltration. However, the influence of early coexisting degenerative changes on RCT outcomes is unappreciated. The purpose of this study was to calculate the impact that pre-existing partial glenohumeral cartilaginous changes have on patients undergoing arthroscopic RCT repair. Methods: A study of 54 patients undergoing arthroscopic RCT repair was undertaken. The presence of co-existing patches of glenohumeral degenerative cartilaginous changes and RCT size was recorded at surgery. Pre- and postoperative outcomes were assessed using traditional (Oxford Shoulder Score [OSS], 5-level EuroQol-5D [EQ-5D-5L] questionnaire and EuroQol visual analog scale [EQ-VAS]) and patient-centric re-formatted prisms. Outcomes were assessed as an entire dataset, and sub-group analysis was performed according to the grade of co-existing arthritis and tear size. Results: Significant improvements (p<0.05) in clinical outcomes were recognized when assessed using either the traditional or reformatted prisms (average % improvements in OSS, EQ-5D-5L and EQ-VAS were 47%, 33% and 43%, respectively; average improvements in pain, function, and psychological well-being were 48%, 33% and, 29%, respectively). Positive gain was noted in all sub-groups of arthritic grading and tear size. Conclusions: Good clinical outcomes can be achieved following RCT repair even in the presence of local partial degenerative cartilage changes and advancing tear size. These benefits are patient-centered but require RCT repairability.

  • Introduction: Buthūr Labaniyya (Acne vulgaris) is a multifactorial disorder of the pilosebaceous units characterized by non-inflammatory and inflammatory clinical lesions. Several Unani medications have been used for centuries to treat acne. Objectives: Evaluation of safety and efficacy of Tila-i Muhāsā in patients with acne vulgaris Materials and Methods: This clinical study was conducted in patients with acne vulgaris. Patients applied Tila-i Muhāsā or 5% Benzoyl Peroxide (BPO) once daily for 6 weeks. Assessment of efficacy was carried out by Global Acne Grading System (GAGS) and Patient Global Assessment (PGA) scores. In addition, overall severity of acne was evaluated on a 5-point Cook's acne grading scale using photographic standards. Assessment of safety was performed through adverse drug reactions, local dermal tolerability, vital signs, and routine laboratory investigations. Results: A total of 60 patients (30 in each group) completed 6 weeks of treatment. The mean percentage reduction in GAGS score at 6 weeks from baseline in Unani group (66.97%) and BPO group (59.09%) was statistically significant (P<0.0001). After 6 weeks of therapy, the mean percentage reduction in PGA score compared to baseline in Unani group (57.44%) and BPO group (50.23%) was statistically significant (P<0.0001). No serious adverse events were reported in both groups; however, mild adverse events occurred more frequently in BPO group (30%) compared to Unani group (10%). Conclusion: Tila-i Muhāsā was found to be effective and safe in the treatment of acne vulgaris. However, further clinical studies with larger sample size and longer duration of therapy need to be conducted.
