Ⅱn this study, the Highway zones that have a passing lane or a concession lane out of annexed lanes to bi-directional two lane Highway were investigated. Characteristics of the highways according to geometrical structure were analyzed and LOS analysis was performed for each zone. The results are as follows; 1. The correction index for existing heavy vehicles should be considered in field limit speed because of the enhancement of the vehicle speed. 2. When analyzing traffic flow, it is more desirable to establish concession zones rather than to have more passing lanes, which are easily influenced by opposite side traffic flow. As this study investigated annexed lanes of highways only, those of local roads should be studied further.

Before 1970, mandibular overgrowth was known as main cause of skeletal Class Ⅲ malocclusion in growing children; however, recent study reports that many skeletal Class Ⅲ malocclusion patients also show maxillary deficiency. Since 1972, when Delaire re-accommodated Protraction Head Gear (P.H.G). many researchers have reported that skeletal Class Ⅲ discrepancies could be corrected through use of P.H.G., which induces anterior movement of maxilla and change in mandibular growth pattern into infero-posterior direction ; nevertheless, it is very difficult to predict resultant changes of orofacial region. The purpose of this study was to find out what treatment effect P.H.G., has on different study samples. Author divided 51 skeletal Class Ⅲ malocclusion patients with maxillary deficiency who were treated with P.H.G. into different study groups depending on sex, treatment beginning age, intraoral appliance, and facial growth pattern. By doing so, following results were obtained. 1. Treatment beginning age and Sex Four age groups (5.8 to 8 year-old, 8 to 10 year-old, 10 to 12 year-old, 12 year-old, 12 to 14 year-old) were compared, and no significant difference was observed. (p<0.05) There was no significant difference between the sex groups, either. (p<0.05) 2. Intraoral appliance Treatment effects of study groups that used R.P.E(mean age of 10.2) and Labio- Lingual appliance(mean age of 8.9) were compared. There was no significant difference depending on the type of intraoral appliance that was used. (p<0.05) 3. Facial growth pattern 1) Amounts of SNB and ANB corrections were smaller in clockwise growth pattern group than those in normal or counterclockwise growth pattern group. (p<0.05) 2) Amounts of increase in wits appraisal and mandibular plane angle were greater in counterclockwise growth pattern group than those in normal or clockwise growth pattern group. (p<0.05) 3) Amounts of increase in articular angle were greater in counter clockwise growth pattern group than those in clockwise growth pattern group. (p<0.05).

This paper attempts to apply input-output(I-O) analysis to investigate the economic impacts of the advertising industry in the national economy for the year 2003, with specific application to Korea. A static I-O framework is employed, focusing on three topics in its application. First, the impacts of the production or investment in advertising industry on the production, valueadded, and employment of other sectors are explored by using demand-driven model. Second, the impacts of the supply shortage in advertising industry on other sectors are looked into by using supply-driven model. Third, the impacts of the rise in advertising rate on prices of other products are discussed by using Leontief price model. This paper pays particular attention to the advertising industry by taking the industry as exogenous and then investigating its economic impacts. In addition, inter-industry linkage analysis is performed to obtain information on the forward and backward linkage effects to quantify the strength of causation among industries. It can be summarized that the advertising industry has a high production-inducing effect, a high supply shortage effect, a low pervasive effect of price change, a low forward linkage effect, and a high backward linkage effect.

Objective : Achyranthes bidentata radix (Usul) has been used as anti-arthritic, antiallergic, antidiuretic and so on Recently extracts of Achyranthes bidentata radix have shown anti-inflammatory and cancer preventive effects in vitro and in vivo. Methods : We therefore evaluated the inhibitory potential of ehtanol extracts of Achyranthes bidentata radix on cytochrome P450(CYP) isoforms-catalyzecd reactions, which relate to causes of cancer and inflammation, including CYP1A2, CYP2C9, CYP2C19, CYP2E1, CYP2D6, CYP2C8, and CYP3A4, using human liver microsomal preparations. Results : The extracts showed weak or negligible inhibitory effects on CYP2C9-catalyzed (S)-warfarin 7-hydroxylation, CYP2C19-catalyzed S-mephenytoin 4-hydroxylation, and CYP2D6-catalyzed dextromethorphan O-demethylation with each IC50 over 1750 g/㎖, respectively. However, it showed relatively significant inhibitory effect on CYP1A2-catalyzed phenacetin O-deethylation and CYP2E1-catalyzed chloizoxazone 6-hydroxylation with IC50s of 970.5 g/㎖ and 821.4 g/㎖, respectively. Conclusions : These results suggest that extracts of Achyranthes bidentata radix have inhibitory effects on CYP-catalyzed reactions, expeciallyCYP1A2 and CYP2E1, in human liver microsomes. These effects appear to relate to anti-inflammatory and cancer prevention following decrease of reactive oxygen species formed by CYP, especially CYP1A2 and CYP2E1, by Achyranthes bidentata radix. However, further evaluation is necessary to demonstrate and to confirm its effects in human.

경기도농업기술원에서는 2016년도에 고온기 생육 및 개화 특성이 우수한 절화용 스프레이 국화 ‘Perky Star’ 품종을 개발 하였다. 2012년도에 화색이 진한 노란색이면서 좁고 긴 설상화를 가진 ‘Sei-vista’ 품종을 모본(♀)으로, 화형이 좋은 ‘Amisa’ 품종을 부본(♂)으로 인공교배를 하였고 2014년부터 2016년까지 억제재배, 촉성재배, 가을재배 작형에서 생육 및 개화특 성을 검정하였다. 2016년 기호도 조사를 통해 최종적으로 GCS12-81-150계통을 선발하여 ‘Perky Star’로 명명하였고 2017 년에 국립종자원에 품종보호출원(제2017-64호)한 후 2018년에 품종보호권이 등록(제7465호)되었다. ‘Perky Star’ 품종은 노란 색 홑꽃형으로 고온에서 화색발현과 생육이 좋았으며 꽃잎이 두꺼워 여름철 수출품종으로 적합하다고 판단되었다. 가을재 배작형, 억제작형, 촉성작형에서 단일처리 후 개화소요일 수는 각각 49, 49, 53일, 절화장은 88.3, 84.2, 103.3cm, 꽃의 직경은 5.1, 4.8, 4.8cm, 줄기당 착화수는 25.0, 21.5, 38.8개로 고온에서 절화장과 착화수가 증가하는 경향을 보였다. 흰녹병 에 완전한 저항성을 갖지는 못한 품종이며, 자연개화 작형에서 절화수명은 21.3일로 대조품종 20.2일에 비해 조금 길었고, 5점 척도로 기호도를 조사한 결과 4.2점으로 대조품종 4.1과 비슷한 선호도를 보였다. A new spray chrysanthemum (Dendranthema grandiflorum) cultivar ‘Perky Star’ was developed at Gyeonggi-do Agricultural Research and Extension Services, Korea, in 2016. Cultivar ‘Sei-Vista’, which has dark yellow colored flower and narrow and long ray floret, was crossed with ‘Amisa’, which has good flower shape, in 2012. This attempt was conducted to breed well-growing varieties at high temperatures period. The growth and flowering characteristics of the lines were investigated in retarding, shading and natural condition from 2014 to 2016, and a preference investigation was carried out in 2016, resulting in the GCS12-81-150 line being finally selected and named ‘Perky Star’. An application was made for a plant variety protection right for ‘Perky Star’ in 2017 (No. 2017-64), which was granted in 2018 (Korea Seed & Variety Service No. 7165). ‘Perky Star’ has single type flowers with yellow petals. This cultivar is suitable for export in summer season because it has good expression of the flower color and grows well at high temperatures and its petals are thick. In the autumn, spring, and summer cultures, the numbers of days to flowering under short day treatments were 49, 49 and 53 days, the plant heights were 88.3 cm, 84.2 cm, and 103.3 cm, the flower diameters were 5.1 cm, 4.8 cm, and 4.8 cm, and the numbers of flowers per stem were 25.0, 21.5, and 38.8, respectively. The cultivar ‘Perky Star’ was not fully resistant to white rust, showed the vase life of 21.3 days in autumn and got the preference degree of 4.2 in 5 points.

Lim Seung-Bin,Kwon Ho,Kwon Sam-Young,Choi Seung-kil,Baek Soo-Hyun,Lee Ju The Korean Institute of Electrical Engineers 2005 KIEE International Transactions on Electrical Mach Vol.b5 No.2

This paper presents an analysis of the permanent magnet overhang effect for the permanent magnetic actuator. Generally, the overhang is often used to increase the force density in permanent magnet machineries. The overhang is particularly profitable in reducing the volume after increasing the force density per volume when using the overhang effect of the permanent magnet. Therefore, the 3D Equivalent Magnetic Circuit Network Method (3D EMCN) has been used in this paper. According to the plunger position, the flux distribution per overhang length and the holding force are quantitatively compared. Furthermore, an appropriate length of the overhang has been proposed. To confirm the accuracy of the analysis method, the results of 2D FEM and 3D FEM are compared for the basic model.
