Apple blotch-like symptoms (ABLS) were observed on 'Fuji' apple leaves in Cheongsong, Gunwi and Yeongcheon apple orchards located in Gyeongbuk Province during 2010-2014. Characteristics of ABLS were yellowing, brown spots on leaves, and defoliation, similar to apple blotch diseased (ABD) leaves, which are infected with Marssonina coronaria. It is difficult to differentiate by eye between ABLS and ABD, which has led to misdiagnosis and overuse of fungicides. The present study was conducted to investigate the cause of ABLS using stereomicroscopy, culture isolation, cross-sectional analysis of leaves, and PCR. No acervuli were found on the surface of ABLS leaves and no growth was observed on potato dextrose agar (PDA) plates in culture. Furthermore, cross-sectional analysis revealed similar results, and mycelia were absent in ABLS leaves. By contrast, all these characteristics were present in ABD leaves. Furthermore, no fungi or viruses were detected in ABLS leaves by PCR, suggesting that the disease is not caused by these agents. These findings suggest that ABLS might be a physiological disorder in plants that is distinct from ABD.

This survey was carried out to investigate the seroprevalence of Neospora caninum in Korean indigenous cattle that was raised in the southern area of Gyenongbuk and Ulleung-gun. A total of 3,162 cattle from 984 farms were tested for the presence of antibodies against N. caninum using a commercial ELISA (IDEXX Switzerland AG, Liebefeld-bern) test kit. The Seropositive ratio of cattle was 1.38% (40/2,901), 0.77% (2/261) in the southern area of Gyeongbuk and Ulleung-gun, respectively. Regional seropositive rates of farms were 5.31% (11/207), 3.45% (4/116), 1.48% (2/135), 2.13% (2/94), 2.78% (3/108), 3.91% (95/128), 4.17% (4/96), 4.35% (3/69), 6.45% (2/31) at Gumi, Yeongcheon, Gyeongsan, Gunwi, Chengdo, Goryeong, Senogju, Chilgor and Ulleung-gun, respectively. A herd of cattle under 4 years old was 1.4% (28 heads), and above the age of 5 years was 1.1% (14 heads). and in seroprevalenec cattles by herd size farms raising under 100 heads were 39 heads.

The cultivation methods of Acanthopanax in Korea need to be optimized. Hence, this study investigated the effect of different fertilizer ratios and planting dates on the growth and acanthoside D content of two (2) Acanthopanax species. The current recommended fertilizer rate of 10.5-8.5-8.5 $kg/ha^-$ ($N-P_2O_5-K_2O$, respectively) produced the best plant growth of Acanthopanax. For the first year, the acanthoside D content resulting from the 2P (2x phosphate) rate was higher than that from the other fertilizer ratios, yet there were no significant differences resulting from the various treatments for either Acanthopanax divaricatus or Acanthopanax koreanum. Similarly, for the second year, there were no significant differences in the acanthoside D content resulting from the various fertilizer ratios, although for both species the acanthoside D content resulting from the 2P rate was slightly higher than that from the other treatments. Therefore, the results indicated that doubling the amount of phosphate increased the acanthoside D content. Plus, the optimum planting date with respect to growth and productivity for Acanthopanax divaricatus was identified as April 15.

Purpose: The present study was to investigate effects of scapular position and pain on a trunk stabilization exercise with gym ball for patients with arthroscopic rotator cuff repair. Methods: Subjects were patients after 2 weeks of rotator cuff repairs. Subjects were randomly assigned to conservative treatment group (CTG, n=10) or trunk stabilization with gym ball group (SBG, n=10), and participated one of those groups for 2 weeks. Measurements about pain and scapular position were assessed in before and after treatment programs. Results: Pain reduced in both rest and night in SBG compared to CTG. In the case of scapular position, decreased scapular retraction (increased protraction) was found in CTG and vice versa in SBG. Reduced scapular anterior tilting was also found on SBG. Conclusion: The present study showed that early performed trunk stabilization with gym ball could bring a scapular alignment that increases subacromial space and reduces pain. This suggests early trunk stabilization with gym ball programs to restore shoulder functions for patients with rotator cuff repair.

A human Echinostoma hortense infection was diagnosed by gastroduodenoscopy. An 81-year-old Korean male, living in Yeongcheon-shi, Gyeongsangbuk-do and with epigastric discomfort of several days duration, was subjected to upper gastrointestinal endoscopy. He was in the habit of eating fresh water fish. Two live worms were found in the duodenal bulb area and were removed using an endoscopic forcep. Based on their morphological characteristics, the worms were identified as E. hortense. The patient was treated with praziquantel 10 mg/kg as a single dose. The source of the infection in this case remains unclear, but the fresh water fish consumed, including the loach, may have been the source. This is the second case of E. hortense infection diagnosed by endoscopy in Korea.

This study deals with rural village development project of Gasangri, Yeongcheon city area, based on the use of the cultural factors and strengthening them in study area. Unlike other cases of today's Korean rural village development projects, this plan keenly concerns not only for tourists but also for the village people. Since culture means the quality of life also, this project especially deals with 'community', 'well-being', and 'convenience' for the inhabitants. On the other hand, it attempts to connect with "Cyan Museum", which is the first grade art gallery remodelled from closed school, to make village of culturally abundant atmosphere. In result, seven sub-projects of the expansion of basic living foundation, and two improvement of landscape in area have planned. Among stereotype of rural development projects and similar programs of tourism, the project makes difference on targeting for the meaning and resource of place culture.

This study investigated the characteristics of outdoor advertising in downtown streets where the local governments improved and maintained. The purpose of this study was to examine how they met outdoor advertising guidelines in the basic landscape plan and how they contributed to the improvement of urban landscape. The outdoor advertising improvement project of local governments has contributed to the formation of downtown street landscape. However, as outdoor advertising is increasingly occupied in the landscape, it becomes a factor that hinders the landscape. Moreover, as outdoor advertising aims at advertisement, unique outdoor advertising has appeared, which is not matched with the surroundings. Therefore, it is necessary to take complementary measures. This study is a basic study to investigate the characteristics of outdoor advertising improvement which is a key element of urban landscape formation. Therefore, further study should be conducted on how an improved street image is evaluated.
