This survey was carried out to investigate the seroprevalence of antibodies to Neospora caninum in Korean native cattle (KNC) raised in Kangwon province in Korea. A total of 867 sera collected from KNC were tested for N. caninum antibodies using an indirect immunofluorescent antibody test (IFAT). One hundred and fifty five (17.9%) KNC were positive by IFAT. Seroprevalence of cows was 19.6% (44/224) and seroprevalence of boars was 17.3% (111/643). Among the seroprevalences of cattle according to the raised areas, five counties or cities, Hwacheon was 33.3% (1/3), Wonju was 30.8% (4/13), Chuncheon was 25.8% (24/93), Hongcheon 18.3% (22/120) and Wheongsung was 16.6%(104/628). It was proved that KNC raised in Kangwon provinces exposed extensively and seriously to N. caninum.

Mites in the family Veigaiidae, order Mesostigmata, subclass Acari are widely distributed in subsoil habitats. They are mostly free-living and predaceous on small arthropod eggs and larvae, and prefer habitats with rich organic matters including litter and humus layers of forest soil. The genus Veigaia Oudemans, 1905 of the family Veigaiidae (Acari: Mesostigmata) is one of the ubiquitous genera from the Holarctic Region. Until now, only two genera and five species of the family were recorded from Korea. Here we provide a report of the species Veigaia tibbetsi Farrier, 1957 with detailed redescription. Even though V. tibbetsi had appeared in some ecological literature, this is the first record of this species in Republic of Korea. This species was mostly found from pine forest(Pinus densiflora) of northeastern mountainous parts of the Korean Peninsula, in Gangwon and Gyeongbuk Provinces. We provided some ecological characteristics of the family Veigaiidae, which will help to further exploration of acarine biodiversity.

This study was conducted to investigate the labor requirements and transportation cost of paddy for the different harvest and transportation systems for obtaining a basic reference to the improvement of present harvest-transportation systems. One hundred and eighty five farm households with sack type combine harvester and thirty farm households with bulk type combine harvester were surveyed for thirty counties from eight provinces except jeju and also eleven Rice Processing Complex were covered for this survey. This survey was carried from 8th. October 1997 to 5th. November 1997. For the labor requirements, bulk trailer system require 6.8th/ha, 10.3/ha for sack harvest-tractor trailer, and 8.8h/ha for bulk harvest-container bag. The machinery utilization cost for the different paddy harvest-transportation systems, combine sack harvest-tractor trailer system is 282 thousand won/ha, and most economical compared with other systems. Combine bulk harvest with tractor system was 416 thousands won/ha and combine bulk harvest with container bag system was 446 thousands won/ha. In order to propagate bulk harvest-transportation system, a proper bulk transportation means with considering road condition in the paddy field and paddy size should be developed, and considering cycle time it appeared that the proper capacity of bulk container was 3.5ton at the present.

The impact of investment on economic growth has been studied by many authors around the world with different times and research methods. Therefore, there are conflicting opinions about the impact of investment on economic growth. To contribute empirical evidence, the objective of this study is to assess the impact of investment sources such as public investment, private investment, and foreign direct investment on economic growth in Vietnam in the short-run and long-run. The data used for the study is panel data from 63 Vietnamese provinces between 2000 and 2020. The inquiry method is PMG (Pool Mean Group) regression for economic growth (GDP) after testing the stationarity of the variables that meet the PMG regression condition as suggested by Pesaran et al. (1996) and Hamuda et al. (2013). The results show that: factors such as labor and trade openness have a negative impact on economic growth in the short term. In the long run, public investment has a negative effect on economic growth, while domestic private investment, foreign direct investment, trade openness, and labor have positive effects on economic growth. Labour contributes the most, followed by trade openness, foreign direct investment, and domestic private investment. Finally, the study provides policy implications for the Government of Vietnam.

This study aims to obtain empirical evidence about the cognitive effect of Islamic religiosity and budget control in reducing budgetary slack behavior. This study involved 176 managers as respondents in 10 local companies in Eastern Indonesia. Managers who are respondents in thus study work and are spread across 14 provinces in Indonesia. Probability sampling method has been used for this study from the total population with certain criteria. Data analysis has been done using Warp PLS-SEM technique. The results showed that Islamic religiosity cognitive and budget control had a direct negative effect on budgetary slack behavior. The two variables also fully mediate the relationship between participatory budgeting and budget-based compensation schemes on the behavior of budgetary slack in a negative and significant way. These results mean that the two variables are proven to reduce budgetary slack behavior. This empirical evidence at the same time corrects the agency theory's assumptions about opportunistic human nature and always maximizes every potential economic profit. In addition, the results also show that Islamic religiosity cognitive is stronger in reducing budgetary slack behavior. These results can be used to improve the company's budget control system by incorporating elements that motivate religious goals so that it is more effective in reducing budgetary slack behavior.

Epidemiological and statistical observations were made of fire hazards that occurred during the past 18 years, 1948 to 1965. Injury and mortality rates for all ages were computed chronologically. For the years of 1955, 1961 and 1965, all fire accidents were epidemiologically analysed to draw characteristic patterns in relation to the seasonal and 24 hour distribution, causes and sites of accidents etc.. Fire hazards observed herein are the categorys E 916 of the International Classification of Causes of Death, 1955, and includes all accidents caused by fire and explosion of combustible materials. The following conclusion was made: 1. The average number of annual deaths due to fire was 183 and the number of the in jured due to the same cause was 335. The mortality rate per 100,000 population was 0.8 and the ratio of injuries per death was 1.83. 2. The casually rate including both the dead and injured was 5.0 per 100,000 in Seoul, the highest among the provinces and followed by 3.4 in Cheju -Do, 2.1 in Kangwon-Do, 1.7 in Kyunggi-Do accordingly. The other provinces had a range of 0.6 to 1.2. 3. The monthly distribution of fro accidents showed that the winter months, December through February, had more frequent accidents, while the summer season, June through August had less. The 24 hour distribution of accidents showed more cases from 12:00 to 18:00 and less from 4:00 to 10:00 hours. 4. The per cent distribution of causes of accidents showed; 90.0% for careless, 10.0% for arson. The cause of carelessness was further breakdown into; 15.0% for kitchen fire places, 13.8% for fire playing, 9,4% for electrical heating and wires, 8.3% for fuels, 6.3% for matches, 5.2% for ash dumps and the remaining for others. 5. The accidents as classified by place revealed that 56.8% of the total occurred at the common dwelling houses, 11.3 at various industrial workshops, 9.3% at the street shops and the remaining at the miscellaneous places.
