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.

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.

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.

This study analyzes chinese cabbage kimchi‘s consumption changes with questionnaire survey of 700 household consumers‘ panel data from 2009 to 2014. Moreover, we analyze factors of preference of salted chinese cabbage using logit model. This study results were as fellow. First of all, Kimjang kimchi is steadily increasing proportion that makes it youself due to focusing on quality and safety of the source material and making kimchi that is palatable to their family. Secondly, the result of the survey has shown that resistance of the consumers has been reduced by little while import of chinese kimchi is steadily increasing. However, consumers still have greater preference for domestic kimchi. Thirdly, preference of the salted chinese cabbage is rapidly increasing because of the cumbersome of salted process and time-saving. Finally, the results of logit model and marginal effect show that a household who is more cumbersome to trim source material and has the higher income and lives in an apartment is preferred salted chinese cabbage more. This means that the convenience of consumption of food is also reflected chinese cabbage consumption in the kimchi-making season.

This study analyzes the price efficiency and causality between wholesale prices and retail prices of chinese cabbage in the five areas` consumer markets using time series analysis methods. The wholesale prices of chinese cabbage in five areas` consumer markets aim for price stability in the long-term and converge on the equilibrium price at a rapid speed although those deviate from the equilibrium price in the short-term. The retail prices of chinese cabbage in the five areas` consumer markets are about the same like the wholesale prices. But, the convergent speed of retail prices is slower than that of the wholesale prices. In addition, I find that there is the causal relationship between wholesale prices and retail prices in the vertical level of consumer market and that wholesale prices have a great effect on the retail prices. Therefore, the wholesale prices and retail prices of chinese cabbage in the five areas` consumer markets are effectively determined in a horizontal, vertical distribution structure.
