  • The experiment was carried out to examine the effects of planting date on the growth and marketable yield of bitter gourd grown in rain-shield plastic houses. Bitter gourd cv 'Dragon' seedlings were separately transplanted during the months of June, July and August, 2015. The training method of all plants was made with four lateral vines and pinching the main vine. Lateral length of plants exhibited no significant difference between each planting date. However, bitter gourd planted in June had significantly higher main stem diameter than those treatments planted on August. The application of planting date was found effective in increasing marketable yield and number of fruits. June, as a planting date, had the highest marketable yield (6,439kg/10a), whereas bitter gourd planted in August had the lowest yield (870kg/10a) which were also consistent in terms of the number of fruits. Fruit length and diameter had no significant differences as affected by treatments. Therefore, planting date of bitter gourd in June was effective in increasing yield of fruit in rain-shield plastic house conditions.

  • This study investigated the process of change of 32 urban parks designated during the period of Japanese colonial rule according to growth and development of the city in Busan. Particularly, researching included analyizing books, notification, data, and documents relevant to the history of urban planning published by Busan city. As a result, Daejeong Park, Gokwan Park, and Yongdusan Park had been utilized by Japanese residents under the Japanese colonial rule before planning of urban parks, and 32 parks legally specified in 1944 were planned by considering the prevention against disasters. After emancipation, there were an unauthorized building, housing construction, business district, public office, and school facility in the sites of the parks due to the influence of the Korean War and reorganization of urban planning. The majority of parkways and small parks downtown were eliminated. However, unexecuted parks that the government had designed on the edge of town during the Japanese colonial period have become major parks downtown through the city's growth. Yeonji Park, Yangjeong Park, and Danggok Park have been being building as a business of parks for a comfortable city, forming downtown along with the Green-Busan Policy. Thus, 32 parks designated under the Japanese colonial rule have made or got out of use reflecting on the phases of the times of modern Korean society. It turns out that these parks need an investigation about condition for land possession and purchase of the site of the parks in order for social common capital.

  • ln this study we isolated 27 isolates of Campylobacter jejuni from stool samples of 882 diarrheal patients. The seasonal distribution of patients was highest at July (11.7%). All the isolates of C. jejuni hydrolyzing sodium hippurate were serotyped on basis of heat-stable antigens, and identified with the use of passive hemagglutination assay. A total of 59.3% among 27 C. jejuni isolates were identified into 6 different serotypes, which serotype HS2, HSl/44, and HS2l were dominant. Antibiotics resistant rates of C. jejuni isolates were shown to be 100%, 63.0%, 51.9%, 37.0%, 33.3%, 25.9% and 7.4% to cephalothin, trimethoprim- sulfamethoxazole, tetracycline, ciprofloxacin, ampicillin, gentamycin and clindamycin, respectively. All isolates were sensitive to the erythromycin and imipenem.

  • We measured salinity and $^{222}Rn$ concentration to explore submarine spring along the coastal areas (Mundongri, Icheon-ri, Jukseong-ri, Daebyeon-ri, Yeonhwa-ri, and Dadae-po) including Ilkwang Bay of Busan Metropolitan City in 2009 and 2010. Before field observation, we selected the potential and possible locations of submarine spring based on the lineament distribution and rose diagram analysis. Salinity and radon concentration were measured within the 1~2 km from the coastal lines. Radon activity decreased gradually from onshore to offshore. Vertical profiles of salinity at some stations showed lateral transport of water mass characterized by low salinity. Vertical profiles of salinity in the Ilkwang Bay, which is a unique bay in the south-eastern coastal area of Busan Metropolitan City, also showed the occurrence of low salinity in the bottom seawater. Our results suggest the possible occurrence of submarine discharge of fresh groundwater in the coastal areas around Busan Metropolitan City. In the future, intensive research should be conducted for the exploration methods of submarine spring as well for the possible utility of submarine groundwater as alternative water resources.

  • This study was performed to survey the distribution of Listeria spp. in fresh agricultural products in the Busan area, the Republic of Korea, from January to November 2022. We investigated the pathogenicity and epidemiological relationships by tracing isolated strains using polymerase chain reaction and pulsed-field gel electro-phoresis (PFGE) methods. Forty cases of Listeria spp. were detected in the 210 samples of fresh agricultural products analyzed. Four species, Listeria rocourtiae, L. innocua, L. grayi, and L. monocytogenes were detected only in green vegetables (lettuce, perilla leaps) and the others (L. innocua, L. monocytogenes, and L. grayi) were detected in enoki and oyster mushrooms. L. innocua was detected in 22 samples and L. grayi in six samples. L. monocytogenes, which causes foodborne diseases, was only detected in enoki mushrooms and the strains that were isolated had genes responsible for the pathogenicity of listeriosis (iap, prfA, inlA, inlC, inlJ, and hly). To investigate the genetic similarity and contamination route of L. monocytogenes, serotyping and PFGE were conducted for 12 strains isolated from fresh agricultural (10 strains) and poultry (2 strains) products distributed at a market in the Busan area. Two serotypes (1/2a, 1/2b) were detected in strains isolated from the agricultural and poultry products, but serotype 1/2b was only detected in strains isolated from agricultural products. PFGE analysis showed index of similarity values of 45.7 to 100% and the same patterns were represented in isolates from some enoki mushrooms. These isolates had the same serotypes and showed significant epidemiological relationships.

  • Choryang Waekwan was the biggest Japanese settlment to house the Japanese diplomatic mission and traders in Korea. Waekwan means Japanese Pavilion literally, but the reality of this Waekwan exceeded much the scale of single architecture. Since Choryang Waekwan was closed in the second half of the nineteenth century, the site of this settlement grew rapidly as the downtown of Busan, which was the first port open to foreign countries in modern Korea. The formation of modern port owes much to the presence of Japanese settlment in Lee Dynasty as long as Choryang was officially designated as the trading port toward Japan and vice versa. Busan is the nearest city to Japan, in fact. Within a day ships could reach Tsushima Island, the island region north of Fukuoka, which played an intermediary role between Seoul and Edo. No architectural remain could be seen on the actual site of Choryang Waekwan. The site has become one of the busiest centers in Busan with quantify of office buildings and shops. The former Busan City Hall was located in this area. The field survey of the site as well as the analysis of historical documents, which were newly found both in Korea and in Japan, enabled to reconstruct the architecture and cityscape of Waekwan by way of computer graphics.
