  • The interpretation of MRI of partial-thickness rotator cuff tears can be challenging. This review describes the anatomic considerations for diagnosing partial-thickness tears, especially supraspinatus and infraspinatus tendon and summarizes the classification of partial-thickness rotator cuff tears, as well as provides an overview on partial-thickness tears with delamination.

  • Purpose: To evaluate the ultrasonographic (US) findings in both shoulders of asymptomatic high school baseball players and compare with healthy control. Materials and Methods: 42 individuals (age: $7.6{\pm}1.2$ years) participated in this study. We recruited two groups of high school male baseball players, 14 pitchers and 18 fielders without shoulder pain for recent 6 months as well as one control group of 10 untrained healthy high school students who were age-matched. Ultrasound measurements of thickness of the biceps and supraspinatus tendon and acromio-humral distance (AHD) at $0^{\circ}$ abduction were taken in dominant and nondominant shoulders. Results: On US examination, subacromial bursa effusion was observed in 7 of the dominant shoulders and in 2 of the nondominant shoulder of 32 baseball players and in none of the asymptomatic controls. The thickness of the biceps and supraspinatus tendons and AHD in both shoulders were significantly greater in the baseball players than in the controls (p<0.05). We also found that the biceps and supraspinatus tendon thickness and AHD of the dominant shoulder were significantly greater than the non-dominant shoulder in baseball players (p<0.05), but there were no differences between pitchers and fielders and between healthy controls. Conclusion: Subacromial effusion could be found even in the asymptomatic stage and the thickness of the biceps and supraspinatus tendons and AHD were significantly greater in the baseball players than in the healthy controls. Our data is useful reference guide for the ultrasonographic diagnosis of shoulder pathologies occurring in high school baseball players.

  • Purpose: To evaluate the ultrasonographic (US) findings in both shoulders of asymptomatic high school overhead athletes and compare with healthy control. Materials and Methods: 33 individuals (age: $17.5{\pm}1.4$ years) participated in this study. We recruited two groups of high school male athletes, 13 baseball and 10 volleyball players without shoulder pain for recent 6 months as well as one control group of 10 untrained healthy high school students who were age-matched. Ultrasound measurements of thickness of biceps and supraspinatus tendon and acromio-humral distance (AHD) at 0o abduction were taken in dominant and nondominant shoulders. Results: On US examination, subacromial bursa effusion was observed in 5 of the dominant shoulders and in 1 of the nondominant shoulder of 23 overhead athletes and in none of the asymptomatic controls. The thickness of the biceps and supraspinatus tendons and AHD in both shoulders were significantly greater in the athletes than in the controls (P<0.05). We also found that the thickness of the biceps and supraspinatus tendon and AHD of the dominant shoulder were significantly greater than the non-dominant shoulder in overhead athletes (P<0.05), but there were no differences between baseball and volleyball players. Conclusion: Subacromial effusion could be found even in the asymptomatic stage overhead athlete and the thickness of the biceps and supraspinatus tendons and AHD were significantly greater in the overhead athletes than in the healthy controls. Our data is useful reference guide for the ultrasonographic diagnosis of shoulder pathologies occurring in overhead athletes.

  • Many ecological studies regarding forest succession, which is the process of arriving at climax forest through ecological changes, have suggested that Carpinus laxiflora is the leading tree type of the climax forest of temperate zone in South Korea. However, most of these studies on C. laxiflora forest have focused on vegetation structure and succession process in specific areas or regional physiognomical forest communities, and thus some may question whether it is rational to consider C. laxiflora forest as the climax forest in South Korea's temperate forest zone. The purpose of this study was to analyze the vegetation classification, species composition, and stratum structure and to investigate the succession tendency with the vegetation data collected from C. laxiflora forests in 75 quadrates in 17 mountains between 2014 and 2017. We used the phytosociological method to analyze the vegetation structure and the importance value to analyze the stratum structure. The results showed the floristic composition of 6 vegetation units and 9 species groups. The hierarchy of the C. laxiflora community group was represented by the Ulmus laciniata community, Corylus heterophylla community (subdivided Quercus aliena group and Corylus heterophylla typical group), and Rhododendron schlippenbachii community (subdivided Fraxinus chiisanensis group, Carpinus tschonoskii group, and Rhododendron schlippenbachii typical group). Successional tendency of C. laxiflora forest based on the importance of each layer is predicted to be the total of three types such as to maintain the stand (vegetation units 2, 3, and 6), to success the Carpinus cordata forest (vegetation units 1 and 4), and to success Quercus acuta forest (vegetation unit 5).

  • The aim of this study was to investigate the quality changes in Supraspinatus muscle of Hanwoo with different packaging methods, such as wrapped packaging (C), vacuum packaging (V) and modified atmosphere packaging (MA). These samples were stored for 25 days under $5^{\circ}C$. Each sample was evaluated for pH, volatile basic mitrogen (VBN) value, purge loss, hardness, meat color and microbial counts. From the results obtained, no significant differences were observed among treatments at the pH. The VBN values of MA were significantly lower than those of C. Also, MA was enhanced stability of meat color compared with other packaging methods during storage days. The purge loss was the most in the V samples, followed by the C and the MA was the lowest. Total bacteria counts of MA sample were significantly lower than those from C. Therefore, it has been concluded that MA could be used as an effective packaging since it extends the shelf life and improve the quality of Hanwoo supraspinatus m.

  • In this paper, we propose the new hardware architecture which implements the stereo matching algorithm using the dynamprogrammethod. The proposed MOEPE(Merged Odd-Even PE) architecture operates in the systolic manner and finds the disparities form the intensities of the pixels on the epipolar line. The number of PEs used in the MOEPE architecture is the same number of the range constraint, which reduced the nuMber of the necessary PEs draMatically compared to the traditional method which uses the PEs with the same number of pixels on the epipolar line. For the normal sized images, the numof the MOEPE architecture is less than that of the PEs in the traditional method by 25${\times}$The proposed architecture is modeled with the VHDL code and simulated by the SYNOPSYS tool.
