In this study, an automatic system for improving the working environment and increasing production efficiency of a laver aquaculture industry in Korea was developed by combining a hydraulic control system and a load cell in a current landing work of the laver. The improved gathering laver system allowed the automatic gathering process of the laver in the sea with the hydraulic control system connected to a cutting machine of the laver on the operating ship, which has been used for gathering the laver semi-automatically in a form of the traditional farming method. The transporting process of the laver from an operating ship to the land was improved as follows. A frame installed on the operating ship and the bag nets were designed and made to hold about 1,000 kg of the laver inside. The bag nets contain the laver on the improved operating ship were tied in knots and hooked on a crane using a load cell. The weight is measured immediately by lifting the bag nets through the load cell system. Weight information is communicated to the fishermen and successful bidders through the application. The advantages of the improved system can help fishermen to fish by improving their working environment and increasing production efficiency. The field survey to improve the landing operation of the laver aquaculture was conducted in Gangjin, Goheung, Shinan, Wando, Jindo, and Haenam in South Jeonnam Province. A total of 10 sites including Gunsan in Jeonbuk Province, Daebu Island in Ansan City, Jebu Island in Hwaseong City in Gyeonggi Province, and Seocheon in Chungnam Province were searched to collect data. Prototypes of the system were tested at the auction house of laver located in Goheung, where laver collection using hydraulic control and landing using road cell could be improved.

Although the majority of elderly are residentially stable, many western studies have recently reported that there has been a gradual growth of retirement migration. However, little is known about that in Korea. Therefore, this study intended to examine the trend and nature of elderly migration. For this purpose, inter- and intra-province migration among the aged 65 and over were analyzed, using the migration data of the Korea National Statistical Office, compiled from the 2000 and 2006 resident registration records. The results were as follows. First, there was an increase of elderly migrants to 531 thousand persons in 2006 from 383 thousand persons in 2000. Secondly, the migration rate of elderly has steadily grown with a 11.7% in 2000 and 12% in 2006. Also, the move of female among old population was active but this trend tended to decrease in 2006. Thirdly, the number of provinces which showed a positive net inter-province migration of old population increased from 7 provinces in 2000 to 8 provinces in 2006. Fourthly, we found that the destinations of elderly migrants were mostly neighboring province except the Chungnam, Jeonbuk, and Jeju. These results suggested that elderly migration would be expected to increase gradually and be important in the future of Korea.

In order to figure out the characteristics of radionuclides concentrations of nine provinces, we analyzed uranium and radon in 681 samples of groundwater. Most of uranium concentrations in each province were less than $10{\mu}g/L$, and Gyeongnam, Jeonnam, Jeju provinces did not have groundwaters exceeding the US EPA drinking water MCL ($30{\mu}g/L$) of uranium. The ratio of radon values exceeding US EPA drinking water AMCL (4,000 pCi/L) was 22.6% (154/681) and Gyeongnam and Jeju provinces had no groundwaters exceeding the AMCL (alternative maximum contaminant level). Uranium and radon concentrations in groundwaters of Gyeonggi, Chungbuk, Jeonbuk, Chungnam mainly composed of the Mesozoic granite and the Precambrian gneiss were relatively high, but the concentrations of Gyeongnam and Jeju widely comprised of the sedimentary rock and the volcanic rock were relatively low. A week correlation between uranium and radon values showed in Gangwon, Chungbuk, Gyeonggi provinces.

Apple scar skin viroid (ASSVd) has been one of the most destructive diseases in Korean apple orchards. Symptoms of the scar skin viroid disease were detected in various apple cultivars, namely, Sansa, Fuji, Chukwang, Miki-Life, Hongro, and Songbongeum cultivated in the southern part of Korea. The RNA molecules were extracted from the apples bearing dapple apple symptoms with the application of CF-11 RNA extraction method. The purified RNAs were used for the synthesis of cDNA with RT-PCR. The PCR products were cloned and sequenced. The viroid RNA molecules from the six different cultivars bearing the dapple symptos showed the same nucleotide sequences as that of the Korean strain of ASSVd（ASSVd-K). ASSVd-K was detected from apple orchards in Kunwi, Sangju, Uiseong, Yeong-yang, Andong, and Youngduk in Gyeongbuk Province in 2001, and in Muju in Jeonbuk Province in 2002. As the viroid disease could be propagated vegetatively, it can be widely transmitted gradually in Korea.

Agricultural water for crops are faced with the need to improve the use efficiency due to the impact of climate change. Water productivity (WP) is known as a good indicator for assessing resources efficiency. This study was conducted to assess WP of rice and potential water consumption (PWC) as new indicator for water use efficiency assessment. The average of WP was 0.7 kg/㎥, and Jeonbuk had the highest WP as 0.83 kg/㎥. Kangwon and Kyungbuk had the lowest WP as 0.59 kg/㎥. PWC showed the same trend because of rice consumption per capita, but Total PWC considering population living in each province showed the different trend with PWC. Every year, the changing patterns of WP was increasing little by little, and the patterns of PWC was decreasing greatly than WP. These results mean that WP has been slowly improved through breed development and irrigation techniques, and PWC was affected by reduced rice consumption and WP increasing. PWC could also be useful as an indicator to compare the water use efficiency between provinces or nations.

Leaf blight of kudzu ( Pueraria lobata ) was found in Jeonbuk province in 2002. The main symptoms appeared as leaf blight and showed yellowing and wilting. The causal pathogen of the leaf blight was isolated from symptomed kudzu leaf and produced white to cream, usually floccose mycelium. It readily formed reddish orange mycelium on PDA. It produced typical microconidia and macroconidia. The microconidia were the reniform. The macroconidia were wide, slightly curved, usually 3 to 4 septate and size was 45 ∼ 85 ${\times}$ 5 ∼ l0$\mu\textrm{m}$. The pathogen produced chlamydospore singly on short hyphal branches within 2 to 3 weeks, which was hyaline, globose, and smooth walled. The pathogen was, therefore, identified as Fusarium solani based on cultural and morphological characters. This is the first report on the leaf blight of kudzu caused by Fusarium solani in Korea.
