  • The survey was conducted for the period from 25 th to 29 th July, 1990. The survey area were selected the mountain area in Kang Won Province. Intake of foods and nutrients of all members in the households surveyed by means of questionnaire was computed based on number of meals a day. On the other hand, daily intake of nutrients by an individual was calculated by sex, age and type of work based on the conversion rate of RDA (Korean Recommended Dietary Allowances for Adult). 1. Status of food intake. The average food intake per person per day in surveyed area was 1103.49 g. The total intake of food was consisted of 44.17% grains, 23.31% vegetables, 10.66% fruits, respectively. These findings led us to the conclusion that people in the surveyed area depended heavily on plant foods. 2. Status of nutrient intake, 1) The average intake of Calorie was 2567.54 Cal Per day, which was slightly higher than 2500 Cal of RDA. 2) The average Intake of protein was 82.92g per day, which was higher than 70g of RDA. Though the quantity was above the RDA, it was largely from plant foods 3) The average intake of calcium was 383.93 mg per day, which was much lower than 500 mg of RDA. 4) The average intake of iron was 11.88 me per day, which was nearly the same quantity as 10 mg of RDA. 5) Intake of vitamin group were high among the inhabitants than recommended by RDA 3. The Kinds of food intake The kinds of food intake in surveyed area were totally 66 different kinds. 4. Economic status. As for the education level, almost of the food handlers finished the primary school and the average monthly income was 364,600 in surveyed area. Households used gas(100%) for fuel.

  • In this study, the pesticide residues in 106 commercial cereal grains were monitored from February to July 2021. For the investigation, 40 domestic and 66 imported products from large, small-to-medium sized offline and online distribution channels, were collected and analyzed by using the multiresidue method for 341 pesticides on GC/ECD, GC/NPD, GC/MSMS, UPLC/PDA, HPLC/FLD, LC/MSMS. Pesticides were detected in total of 8 samples (7.5%), of which one was from big box retailers, two from small and medium-sized distribution stores, and five from online shopping mall. Five (4.7%) samples were found to have pesticide residues greater than the maximum residue limits (MRLs). The detected pesticides in kidney beans (1 case), mung beans (6 cases), and sorghum (1 case), were MGK-264, chlorpyrifos, thiamethoxam, malathion, piperonyl butoxide, and pirimiphos-methyl. Specifically, an excessive amount of thiamethoxam was found from the imported mung bean (5 cases).

  • This study investigated the residual characteristics of bifenthrin and chlorothalonil in crown daisy and suggested pre-harvest residue limits (PHRLs) based on their dissipation patterns and biological half-lives. The samples for residue analysis were harvested at 0 (3 hr), 1, 3, 5, 7, 9, 11, 13, 15, 18, 22 and 26 days after treatment, and analyzed by $GC/{\mu}-ECD$ and TOF/MS. The limit of quantitation (LOQs) of bifenthrin and chlorothalonil were 0.0046 mg/kg and 0.0007 mg/kg, respectively. Recoveries ranged from $88.67{\pm}7.97%$ and $99.90{\pm}16.03%$, showing that this method is appropriate for the analysis of the pesticide residues in crown daisy. Being well within first order kinetics, the biological half-lives of the pesticide residues in crown daisy were 9.63 days for bifenthrin and 6.54 days for chlorothalonil. The PHRLs of bifenthrin and chlorothalonil were recommended as 11.70 mg/kg and 24.10 mg/kg for 26 days before harvest, respectively.

  • In order to confirm the impact of the Positive List System (PLS) being applied to all agricultural products from January 1, 2019, we analyzed 28,693 points of inspection-related data on agricultural products distributed in Gyeonggi-do from 2018 to 2020. The ratio of cases exceeding the standard for the total inspection performance was 1.0% in 2018, 1.2% in 2019, and 1.2% in 2020. Out of the 114 cases exceeding the standard in 2019, 55 were applied on a Maximum Residue Limit (MRL) of 0.01 mg/kg, and out of the 115 cases exceeding the standard in 2020, 66 were applied on a MRL of 0.01 mg/kg. To improve this, it seems necessary to manage unintentional pollution, conventional use for unregistered crops, and illegal pesticides. Fluquinconazole detection resulted from unintentional contamination, and diazinon, chlorothalonil, and methabenzthiazuron detection resulted from conventional use in unregistered crops. Chinomethionat is a pesticide component that was discarded in the past and its current use has been attributed to the smuggling of pesticides. This study and future monitoring data can be used as reference data for system supplementation and on-site management reinforcement.

  • This study was aimed to investigate pesticides residue levels in nuts and seeds distributed in Gyeonggi-do. We investigated nuts and seeds in 131 products, which is pumpkin seeds (n=17), sunflower (n=12), sesame (n=23), perilla (n=11), peanut (n=18), almond (n=8), chestnut (n=6), walnut (n=14), pine nut (n=3), pecan (n=4), macadamia (n=3), brazil nut (n=5), cashew nut (n=4) and ginkgo nut (n=3). As a result of evaluating 339 pesticide residues, eight out of 131 samples were detected at the range of 0.01-0.07 mg/kg. Additionally, 7 out of 8 detected samples exceeded MRLs (Maximum Residue Limits) and 85% of them were imported. Pyraclostrobin applied on the positive list system (PLS) was detected in five Chinese pumpkin seeds samples, and the range was 0.02-0.04 mg/kg. In Indian and Korean sesame seeds, pendimethalin, boscalid, and bifenthrin were detected at 0.04, 0.05, and 0.06 mg/kg, respectively. The ratio of estimated daily intake (EDI) to acceptable daily intake (ADI) was 0.002-0.372%, indicating that the risk level was safe.

  • In 2004, in order to create core competences and major growth drivers for endogenous regional developments, the Korean government adopted the policies for establishing regional innovation systems, The main organization for the policies is the regional innovation council which is composed of diverse groups of scholars, professionals, and government officials. The regional innovation council of Kang-won Province consists of a couple of sub-divisions such as Operation Committee, Administration Office, Planning and Moderation Department, Strategic Industry Department, Culture and Tourism Industry Department, Regional Industry Department, and Regional Human Resource Development Department. The primary roles and jobs are planning, reviewing, evaluating and finalizing regional innovation policies. However, because of conflicts with local government, insufficient budget problems, organization structure problems, and decision making process problems, the regional innovation councils could not perform their original roles and functions. They could not adopt radical or non-traditional strategies. Although it's failure, a lot of people recognize the importance of regional innovation councils' roles and functions, I believe there would be another regional innovation councils coming continuously which would be take more important roles and have more power over budgeting problems. The purpose of this article is to identify the primary sources of strategies and organization structure problems of the previous regional innovation councils and to provide a couple of answers. In this paper, the author primarily analyze the problems of the Kang-won innovation council. A couple of answers to the desirable organization structures and the desirable roles of regional innovation councils will be presented for discussion.

  • To help idntify the potential sources of volatile organic sulfur compounds within the continental environment, we have conducted preliminary measurements of dimethylsulfide(DMS) during field campains held from three reference sites. These sampling sites were located within a waste reclamation facility in Won Ju City, Kang Won Province. The results of our measurements showed that DMS levels spanned over 1 to 55 pptv with a mean and 1 standard deviation(1SD) of 12 and 18 pptv(N=13). In a comparison of the data derived from the strongest sources, i.e., oceanic environment, the DMS levels in thre reclamation facility were jpronouncingly low with high day-to-night concentration ratios. It was noted that a significant difference in DMS levels between daytime and nighttime periods was mainly driven by a few exceptional data measured during daytime. Despite limitations of our measurement data in deriving meaningful interpretations of spatiotemporal distributions of DMS in inland facilities, the existence of extraordinary trends, i.e., especially "lower-than-expectedL" DMS values, can be explained in terms of mixed effects of several factors. Most importantly, we can infer that the rates of DMS production and of its destruction in the study site are at or near steady-state condition. Another possibility is that DMS is not adequate enough to explain the generally malordorous environment of reclamation sites, of particular in Won Ju area.n Ju area.

  • In KOREA, the history of weaving is so long even in prinitive, there are the traces of fabric emmision using Spindle already in the Neolithic age. And coming up to the period of Three States, becoming active of cultivation of fibers, it can be known the variety of kinds and the production of fine products by improvement of new method of weaving using weaving machine. In the period of shilla state, there is a record of making the fine fabrics with 28 bracts. But wearing of silks fabrics was limitted for only the nobility and common people were wearing native thick hemp clothes. Also in the period of Korea state, they were wearing the hemp clothes by cultivation of hemp. The good quality products were worn by the King or the nobility and women in KOREA made their best with whole efforts to pay to the authorities with woven products of hemp clothes, so in the 14th year of King Chung- Ryul, King prohibited the presentation of fine hemp clothes by his order. By the end of KOREA state, before the production, common people was mainly wearing the hemp clothes. Coming up to the Kingdom of Chosun the sericulture was promoted by establishment of the sericulture encouraging low. Therefore the working hours of women were highly increased. The products of Song-do, Chin-ju for cotton clothes, those of Han-san-the same now as in old times-for ramie clothes, those of Han-Kyung province and An-dong for hemp fabrics were estimated as the best qualities. And the hemp clothes of Kang-won province is not so fine but is very useful and famous for mourning clothes and summer clothes for the farmer. It is true that our history of weaving was begun with hemp as a continous and precious friend of common people during all the historical periods-even though for a while it went backward because of chinese silks.
