This study surveyed planting areas along streets in Gangwon-do to find out how to improve the planting and use of street trees and herbaceous plants. There were 301,491 trees of 41 species on the streets of Gangwon-do in 2004. The predominant species of street trees were Ginkgo biloba ($40\%$), Prunus spp. (Prunus yedoensis and Prunus sargentii) ($25\%$), Platanus occidentalis ($5\%$), followed by Betula platyphylla var. japonica, Zelkova serrata, Prunus armeniaca var. ansu, Acer palmatum, and Pinus thunbergii. Eighty-four herbaceous plant species were found in the Youngseo district (the southern area of Gangwon-do); the ratio of native species to exotic was 51:33. The predominant species were Cosmos bipinnatus, Petunia hybrida, Tagetes spp., Aster koraiensis, and Fagopyrum esculentum. Eighty-nine herbaceous plant species were found in the Youngdong district (the eastern area of Gangwon-do); the ratio of native species to exotic was 55:33. The predominant herbaceous plants were Aster koraiensis, Tagetes spp., Petunia hybrida, Rudbeckia bicolor, Cosmos bipinnatus, Salvia splendens, Brassica oleraceae var. acephala, Aquilegia buergeriana var. oxysepala, Coreopsis drummondii, Viola tricolor, and Dianthus superbus var. longicalycinus. Appropriate pruning adds to the aesthetic value of trees and prolongs their useful life; it also maintains good health and thereby reduces the need to control insects and diseases. Street trees had not been properly pruned due to the presence of power lines and a shortage of pruning information. The pruning was controlled by Korea Electric Power Company, which has no pruning information. Pruning must be maintained by a professional landscape company in order to maintain good shape, such as that which is done for bonsai. In order to improve the planting, use and maintenance of landscape plants in Gangwon-do, the following recommendations are made: street tree species should be diversified, suitable street trees should be selected for each space, native species should generally be used, trees should be appropriately pruned and properly fertilized, pests and diseases should be controlled, plantings should be done in multiple layers, spatial arrangements should be improved, larger trees should be planted, and drainage and underground electric wires should be considered when planting.

This study was executed to find out how to improve the planting and use of landscaping plants in Chuncheon. The number of street trees was 17,877 in 2003. The major species of street trees were Ginkgo biloba(52.7%), Prunus sargentii(15.3%), Zelkova serrata(8.9%), Platanus occidentalis(7.3%). Salix babylonica and Platanus occidentalis were decreased, while Prunus sargentii and Zelkova serrata were increased. Salix babylonica is a good species for a lakeside city, but its seeds cause allergies to some people. Most of the trees have been removed in Chuncheon. The planting of Salix babylonica(♂) resulted in no problems, and it should be propagated to plant. The soil of several areas was analysed to investigate soil conditions. The outskirts of city had good conditions in pH, organic matter and minerals, but the downtown areas had high alkalic, due to alkali from footpath concrete blocks. Appropriate pruning adds to the aesthetic and prolongs the useful life; it also requires less managing of insects and diseases to maintain good healthy of street trees. Street trees were not properly pruned due to electric lines and shortage of pruning information. The pruning was controlled by Korea Electric Power Co, which has no pruning information. Pruning must be maintained by a professional landscape company to maintain good shape such as with Bonsai. The Shrubs planting zone between street trees and other trees, and preservation plates were established for healthy of street trees. They have to be repaired and maintained well to keep better environmental conditions. The number of tree and flower species of 68 schools in Chuncheon were 12 and 16, respectively. The species that showed high preference were Juniperus chinensis, Pinus koraiensis, Pinus densiflora, Rosa centifolia, Forsythia koreana, and Rhododendron schlippenbachii. The high frequency of the protection trees designated by Chuncheon were Pinus densiflora, Ginko biloba, Zelkova serrata, Quercus species. It was thought that the diversification of street tree species, the selection of street trees suitable to each space, the generalization of use of native species, the appropriate pruning and proper fertilization, the control of pests and diseases, and the opinions of citizens concerning landscape plants were needed to improve the planting, use and maintenance of landscaping plants in Chuncheon.

Objectives: The purpose of this study was to evaluate the reliability and validity of the instrument on pattern identification for insomnia (PIT-Insomnia) and verify the correlation between PIT-Insomnia and psychological tests. Methods: Two evaluators examined the pattern identification of the participants who met insomnia disorder diagnostic criteria of the Diagnostic and Statistical Manual of Mental Disorder, Fifth Edition (DSM-5) and took the Insomnia Severity Index (ISI) score over 15 once manually and twice using the PIT-Insomnia to measure the inter-rater and test-retest reliability. We also conducted the following surveys: the Pittsburgh Sleep Quality Index (PSQI), the Korean version of Beck’s depression inventory (K-BDI), the Korean version of the State-Trait Anxiety Inventory (STAI-K), the Korean Symptom checklist- 95 (KSCL-95), and the EuroQol-5 dimension (EQ-5D), to measure concurrent validity and correlation between the PTI-Insomnia and psychological tests. Results: 1. The test-retest reliability analysis of the pattern identification results showed moderate agreement, and test-retest reliability analysis of each pattern identification score showed agreements from poor to moderate. 2. The inter-rater reliability analysis of the pattern identification results via manual showed slight agreement, when analysis was performed with calibration, the inter-rater reliability analysis of the pattern identification results via manual showed fair agreement. 3. The concordance analysis between results via manual and the PIT-Insomnia showed poor agreement, when the analysis was performed with calibration, concordance analysis showed fair agreement. 4. The concordance analysis between the PIT-Insomnia and the PSQI showed positive linear correlation. 5. The concordance analysis between the PIT-Insomnia and the PSQI, K-BDI, STAI-K, KSCL-95, and EQ-5D showed that non-interaction between the heart and kidney have positive linear correlation with the K-BDI, anxiety item of KSCL-95, dual deficiency of the heart-spleen have positive linear correlation with somatization item of KSCL-95, paranoia item of KSCL-95, heart deficiency with timidity have positive linear correlation with stress vulnerability item of KSCL-95, parania item of KSCL-95, phlegm-fire harassing the heart have positive linear correlation with K-BDI, paranoia item of KSCL-95, depressed liver qi transforming into fire have positive linear correlation with the anxiety item of KSCL-95, parania item of KSCL-95, all pattern identification have negative linear correlation with EQ-5D. Conclusions: The PIT-Insomnia has moderate agreement of reliability and reflects the severity of insomnia since it has some concurrent validity with the PSQI. There are some correlations between the PTI-Insomnia with specific psychological tests, so we could suggest it can be used appropriately in the clinical situation.

Objectives: This case report intended to examine how herbal medicine treatment for breathing-related sleep disorders applied with polysomnography affected the structure of sleep. Methods: From January to November 2019, we retrospectively reviewed the progress records and polysomnography reports of patients who visited Korean medical hospitals in Daejeon and Cheonan. Results: In case 1, the patient complained of daytime sleepiness and snoring and was diagnosed with obstructive sleep apnea disorder and treated with Ukgan-san-gami. There were significant changes in the polysomnographic parameters, such as sleep efficiency, waking after sleep onset, sleep latency, the total arousal index, and the apnea-hypopnea index after herbal treatment. In case 2, the patient complained of frequent waking after sleep onset, daytime sleepiness, and snoring, and was diagnosed with obstructive sleep apnea disorder and treated with Yeoldahanso-tang-gami. There were significant changes in the polysomnographic parameters, such as the total arousal index and the apnea-hypopnea index after herbal treatment. In case 3, the patient complained of daytime sleepiness and was diagnosed with obstructive sleep apnea disorder and treated with Bangpungtongsung-san. There was no significant change in the polysomnographic parameters after herbal treatment. Conclusions: It is meaningful to note that objectively identifying the outcome of treatment for breathing- related sleep disorders is necessary in the clinical practice of Korean medicine.

현재 분재재배의 큰 문제점은 높은 노동력에 비해 생산성이 매우 낮은 것이다 본 연구는 관수시스템과 관리방법의 개발로 고품질의 분재를 대량생산하기 위해 실시되었다. FRP분상에서 재배된 분재는 직수관수나 스프링클러 관수에 비해 저변관수시스템에서 생육이 매우 좋았다. 또한 저면관수시스템은 노동력을 크게 줄일 수 있었고 짧은 기간에 대량생산을 할 수 있었다. 또한 비닐하우스내(內)에서 저면관수 시스템의 이용은 조기생산은 물론 고품질의 분재를 생산할 수 있었으며 내한성이 약한 수종들도 겨울재배가 가능하였다. 본 연구는 세계시장을 위한 국가경쟁력에 크게 기여하였을 뿐만 아니라 농가 수익에도 큰 도움을 줄 수 있었다. There have been some problems of high labor. low productivity in the existing systems of bonsai cultivation. This study was conducted to cultivate a large quantity of hig-quality bonsai through the development of bottom irrigation system and management method. Bonsai placed on the FRP bed were grown very well by bottom irrigation system compared with direct watering and sprinkler system. It was concluded that bottom irrigation system was possible to reduce considerable manual labor and produce mass production of high-quality bonsai within shorter periods. This research was finally found that the growth was significantly better and earlier production was certain in the vinyl house, had another advantage which could cultivate less cold-resistant species and therefore broadened a range of species selection for market supply. Cultivation techniques by the use of vinyl house and bottom irrigation system developed was quite effective for early production of bonsai as well as for high productive and value added. This project developed a new practical techniques and systems which can make mass and early production of bonsai with high quality through input of less labor. Interest in bonsai is now expanding in landscape horticulture and other fields concerned, and bonsai export of our country is also increasing. Results from this research will make a great contribution to enhancing of bonsai cultivator's competitive position in world markets and to improving of their annual income.

In this paper, we propose a system for extracting features from a large number of data collected in seconds on a moving vehicle and analyzing big data. The system proposed in this paper consists of a system that stores CSV data in a database and a system that accumulates preprocessed data based on the data stored in the database. In order to increase the efficiency of this system, multiprocessing is used. The proposed systems are designed and developed to find meaningful service models as an infrastructure system for developing business services for connected vehicles where data is collected in real time. Due to the nature of the collected data, time information is very important, and OpenTSDB, a NoSQL time series database, is used in consideration of effective analysis through graphs.

본 연구는 시중에 유통중인 한우 사골의 과학적인 거래기준을 제시하고자 성숙도 2(수소), 성숙도 2(거세), 성숙도 3-9(암소)의 한우 반도체 각 4두에서 사골(상완골, 전완골, 대퇴골, 하퇴골)을 구입하여 총 4회 추출한 사골 용출액의 탁도와 색도(명도), 콜라겐과 단백질 함량, 칼로리 및 콘드로이친 황산 함량을 분석하였다. 성숙도 2에 해당하는 한우 수소와 거세우 사골 용출액의 탁도와 명도가 성숙도 3부터 9에 해당하는 한우 암소 사골용출액 보다 유의적으로 높게 나타났다(p<0.05). 추출횟수에 따른 탁도와 명도의 변화는 전체 성숙도에서 2차 추출까지 증가하다가 이후 유의적으로 감소하였다(p<0.05). 성숙도 2에 해당하는 한우 수소와 거세우 사골 용출액의 콜라겐과 단백질 함량이 가장 높게 나타났다(p<0.05). 성숙도 2에 해당하는 한우 수소와 거세우 사골 용출액의 칼로리와 콘드로이친 황산 함량이 성숙도 3부터 9에 해당하는 한우 암소 사골용출액 보다 유의적으로 높게 나타났다(p<0.05). 또한 추출횟수에 따른 콘드로이친 황산 함량 변화는 전체 성숙도에서 추출횟수가 증가 할수록 유의적으로 감소하였다(p<0.05). 이상의 결과를 종합하면, 전체 실험항목에서 성숙도 2(수소와 거세우) 사골용출액과 성숙도 3-9(암소) 사골용출액 간에는 차이가 있었으나, 전체 성숙도에서의 차이는 뚜렷하게 나타나지 않아 성숙도가 사골거래기준으로 적합한지는 보완적인 연구가 추가적으로 수행되어야 할 것으로 사료된다. This study was conducted to investigate the effect of maturity scores [2 (bull), 2 (steer), 3-9 (cow)] and the number of extractions (up to 4 times) on the chemical properties of water extract from Hanwoo shank bones (arm, fore shank, round and hind shank). The turbidity, meat color (CIE L value), collagen, protein, caloric and chondroitin sulfate contents of samples were observed. The turbidity and lightness were higher for water extract of Hanwoo shank bones with a maturity score of 2 (bull and steer) than maturity scores of 3-9 (cow) (p<0.05). The turbidity and lightness of water extract from shank bones of all Hanwoo maturity scores significantly increased with the 1st and 2nd extractions, but significantly decreased with 3rd and 4th extractions (p<0.05). The collagen and protein contents were highest for water extract from Hanwoo shank bones of maturity score 2 (bull and steer) (p<0.05). The caloric and chondroitin sulfate contents were higher for water extract from Hanwoo shank bones of maturity score 2 (bull and steer) than maturity scores of 3-9 (cow) (p<0.05). As the number of extractions increased, the chondroitin sulfate content significantly decreased (p<0.05). Based on these results, differences correlating with maturity scores were found only with collagen and protein contents. Therefore, further studies should be considered to address whether different maturity scores affect the price of shank bones in the meat industry.

Eight subprimal cuts purchased from the branded Hanwoo beef of 3 quality grades ($1^{++}$, $1^+$, 1) at 13 stores were evaluated the tenderness using Warner-Bratzler shear (WBS). The beef frequency ratio (%) depending on postmortem aging periods were investigated. The 37.5 (quality grade $1^{++}$), 45.8 (quality grade $1^+$), and 36.4% (quality grade $1^{++}$) of branded beef were aged for < 7 d, 26.6 (quality grade $1^{++}$), 47.2 (quality grade $1^+$) and 36.4% (quality grade 1) were aged for $7{\sim}13$ d, and 31.3 (quality grade $1^+$), 4.2 (quality grade $1^+$) and 25.8% (quality grade $1^+$) were aged for 14 to 20 d. The temperature of cold room in stores was ranged average 2.27 to $2.42^{\circ}C$. WBS values for ansimsal (tenderloin), witdngsimsal (ribeye), cheggtsal (shortloin), doganisal (knuckle) and moongchisatae (hind shank) from branded Hanwoo beef of quality grade $1^{++}$ were tender than those from branded Hanwoo beef of quality grade 1 (p<0.05). WBS values for ansimsal (tenderloin) were 2.56 (quality grade $1^{++}$), 2.76 (quality grade $1^+$) and 3.10 kg (quality grade 1), respectively, and those for doganisal (knuckle, quality grade $1^{++}$), hongdukesal (eye of round, quality grade $1^+$) and bosupsal (top sirloin, quality grade 1) were 4.76, 4.96 and 5.66kg, respectively (p<0.05). The frequency ratio (%) of WBS < 3.9 kg in the all subprimal cuts from branded Hanwoo beef of quality grade $1^{++}$ were 100 [ansimsal (tenderloin) and cheggtsal (shortloin)], 87.5 [witdngsimsal (ribeye)] and 62.5% [bosupsal (top sirloin)], whereas that of WBS > 4.6 kg were 50.0% [hongdukesal (eye of round) and doganisal (knuckle)]. The frequency ratio of WBS < 3.9 kg in the an subprimal cuts of quality grade $1^+$ were 100 [ansimsal (tenderloin) and witdngsimsal (ribeye)] and 44.4% [cheggtsal (shortloin) and gurisal (chuck tender)], whereas that of WBS > 4.6 kg were 66.7 [hongdukesal (eye of round)], 55.6 [doganisal (knuckle)] and 44.4% [bosupsal (top sirloin)]. The frequency ratio (%) of WBS < 3.9 kg in the all subprimal cuts of quality grade 1 were 88.9 [ansimsal (tenderloin)], 62.5 [cheggtsal (shortloin)] and 44.4% [witdngsimsal (ribeye)], whereas that of WBS > 4.6 kg were 100.0 [doganisal (knuckle)] 62.7 [hongdukesal (eye of round)], 62.5 [gurisal (chuck tender)] and 55.6% [moongchisatae (hind shank)]. From these results, subprimal cuts from branded Hanwoo beef were marketed with short aging periods and high frequency ratio (%) of WBS > 4.6 kg.
