The patellofemoral pint is formed by the articulation of the patella and femoral condyles in the trochlear groove. The complexity of the patellofemoral pint is magnified by the fact that the tibiofemoral pint works in conjunction with the patellofemoral pint. Additionally, other pints such as the subtalar pint., hip and sacroiliac pints indirectly contribute to the function of the patellofemoral pint. This pint has little bony stability, Soft tissue surrounds the pint to increase stability. The patellofemoral pint increases the mechanical advantage of the quadriceps muscles and resists mechanical loading. In patellofemoral dysfunction, patellofemoral contact pattern is disrupted. leading to excessive compression at the pint. When you treat the patellofemoral dysfunction, you should evaluate anatomic and biomechanic components and find factors of patellofemoral dysfunction. Hamstring tightness. weakness of VMO and tightness of lateral retinaculum lead to flexed knee and abnormal patella tracking and patellofemoral pint reaction force and patellofemoral dysfunction. A through understanding of the anatomy and biomechanics may assist the clinician in the recognition and treatment of patients with patellofemoral pain. Therefore physical therapists should apply modality as well as therapeutic exercise, stretching and strengthening. In this paper, I will discuss the germane anatomical structures and biomechanics of the patellofemoral pint.

To observe the anatomical structures which cause a cervicogenic headache it reports, from viewpoint of physical therapist in treatment multiple to observe method which approaches, the reporter it does. With the manipulation the vertebral manipulation effected an affirmative effect to cervicogenic headache(Niels Nilsson et al,1997). The manipulation, soft the tissue massage, postural education/advice, muscular elongation, the traction, and postural exercises initially came to be used with that technique which the upper cervical vertebra(0-C3) passive accessory intervertebral movement comes to be used with a cervicogenic headache treatment technique(Grant T & Niere K., 2000). Also, it relates with the diagnosis standard about a cervicogenic headache when the body function over of the cervical vertebra is discovered, the Muscle energy technique was proposed in the treatment which is safety and effect(Bogduk N,2001). The TENS and the Mange gave a reduction effect of pain often.

Since organized living cooperative associations sold their environment-friendly agricultural products directly to independent consumers in the past, the general distribution channels such as wholesalers had difficulty in handling these products. However, the ratio of distribution via wholesale channel has been gradually increased as consumption of environment-friendly agricultural products has expanded. This study is to address vitalization of wholesale distribution for environment-friendly agricultural products by gathering previous statistical data and analysis. In addition, statistical analysis are conducted by utilizing surveys on forwarders, consumers for environment-friendly agricultural products. As a result, the products producers ship are distributed through dealers at producers sites, producers cooperatives, or food process companies, food companies, internet shopping malls, large-scale distribution companies, consumer groups such as living cooperative associations, direct outlets at consumers sites, or exports. Among the channels, the large-scale distribution companies and franchised special shops account for 47%, the general supermarkets 15.7%, and living cooperative associations 14.6% respectively. By utilizing the research results on producers and consumers, and the distribution weight by channels for environment-friendly agricultural products, the distribution channels for living cooperative associations, wholesale markets, and large scale distribution companies are compared and evaluated. As a result, the level of producers' and consumers' satisfaction for them is the lowest since the low selling price for producers and high distribution margins.

This study aims to identify the impact on chinese cabbage import and the area of local chinese cabbage cultivation when chinese cabbage prices fluctuate due to unstable supplies from unusual weather patterns. For this purpose, the study analyzes monthly data of chinese cabbage cultivation areas, chinese cabbage prices, and chinese cabbage import amount by using a SVAR model, which is useful to describe co-relations of variables— regardless of endogenous or exogenous variables. The analysis result shows that an increase in kimchi import from China decreases chinese cabbage prices and cultivation areas. Notably, the decrease in cultivation areas continues for more than ten months. Besides, our research finds that a sharp rise in local chinese cabbage prices from unusual summer weather conditions increases kimchi import and, as a result, shrinks local chinese cabbage prices and cultivation areas. The reduced local cabbage market causes a rise in chinese cabbage prices when unusual weather patterns occur, forming a vicious cycle. Therefore, instead of passive policies, such as production stabilization and stockpiling, the government should shift to proactive measures by expanding new cultivation areas, especially from August to October to secure stable kimchi supply.

이 연구는 한·중 FTA 체결에 따른 오미자의 시장 파급영향을 계측·분석하여,2014-2018년 동안의 중장기 수급의 변화를 검토한 내용을 담고 있다.오미자에 대한 한·중 FTA체결의 구체적인 내용을 알 수 없는 상황에서,실현가능한 오미 자 시장개방 상황을 시나리오로 구성하여 수급모형에 도입하고,현재 중국산 오미자의 수입상황을 반영하여 분석하였다.오 미자에 대한 중장기 수급 및 가격 전망을 위해 오미자 개별 품목에 대한 별도의 부분균형모형을 구축하였고,모형내 각 방정 식들은 계량경제학 방법을 이용하여 추정하였다.분석결과,관세율이 현행 8%에서 2014년부터 2018년까지 단계적으로 철폐 될 경우,재배면적은 2018년 3,370ha으로 다소 감소하고,소비량은 2018년 12,040.8톤으로 증가하는 것으로 전망되고,생산액 이 5년간(2014-2018)누적으로 약 98억원 수준 감소하는 것으로 추정되었다. This study analyze the impact of omija(maximowiczia chinensis) market by Korea-China FTA and review the change of mid and long term supply-demand from 2014 to 2018. A scenario is also imported to simulate and measure the impacts of the Korea-China FTA. The scenario is that tariff rates for Chinese product(omija) will be zero after 5 years from 2014. A partial equilibrium model of Omija is specified to forecast mid and long term supply-demand and prices. Equations in the model were estimated by using econometric techniques. The results based on scenario are compared with the results by the baseline case(maintenance of current situation). Our study show that when the tariff rates for Chinese product(Omija) will be zero after 5 years from 2014, the cultivated area of Omija is forecasted to decline until 3,370ha in 2018, and the consumption is forecasted to increase up to 12,040.8MT in 2018, and also total revenue of about 9.8 billion korean won will be decreased during 5 years(2014-2018).

The purpose of this study is to analyze the questions in pedagogy for the certification examination of secondary education teachers between 2002 and 2010, in order to discuss the implications for the operation of the teacher`s training course. With such an objective, such things as the trend of setting questions in pedagogy for the certification examination of secondary education teachers, the frequency of certain questions according to the `basic subjects and fields` proposed by the Korea Institute of Curriculum & Evaluation, and the frequency of questions related to the contents of each field of evaluation have been analyzed. The results of the study can be summarized as follows. Firstly, after analyzing the suggested forms of questions in pedagogy and the contents requiring answers, it seems that the suggested forms of questions have become complicated enough to suggest illustrations or examples, instead of simply suggesting forms. Also, the contents requiring answers have suggested the complicated knowledge or the form of understanding, instead of showing the simple knowledge or the form of memory. In particular, the number of questions has been reduced from 50 to 40. Since 2009 when the multiple-choice questions with four examples were changed to those with five examples, such a trend of change has been clearly identified. Secondly, after analyzing the frequency of questions for the six basic subjects and fields, it seems that the questions are based on certain fields of evaluation for most basic subjects and fields. Thirdly, after analyzing the frequency of questions for the contents from each field of evaluation, it has been found that more than 50% of the entire questions are repeatedly chosen. Since it is possible to become teachers only through the certification examination, the forms and frequency of questions greatly influence the operation of the teacher`s training course. The implications suggested by the results of the study on the teacher`s training course have been discussed in various aspects.
