Purpose: In the orbital floor fracture, sensory impairment due to the damage of the infraorbital nerve is one of the most common symptom and complication. In this report, we have the assumption that tailoring of $medpor^{(R)}$ for decompression may have correlations to the damage and regeneration of the nerve. Methods: Among patients who had open reduction for pure orbital floor fracture in our hospital from March 2005 to March 2008, we selected 80 cases. In 40 cases, we inserted tailored $medpor^{(R)}$, and in other 40 cases, non-tailored $medpor^{(R)}$ was inserted. Patient's reports were obtained and analyzed, and the pin-prick test and the 2-point discrimination test on the infraorbital nerve regions were done for testing the sensory impairments. Results: The results show that the patients who adopted sculpture of $medpor^{(R)}$ showed higher tendency of recovery of sensory impairments in the patient's subjective report, static touch sensation, static two point discrimination using. And in postoperative 3 months, there are statistically significant recovery of sensory symptoms, signs and the result of sensory tests. Conclusion: From these results, tailored $medpor^{(R)}$ in reconstruction of orbital wall fracture may improve recovery of sensory impairments for decreasing of compression of infraorbital nerve.

The goal of this study is to segment building points effectively utilizing scan-line characteristics of airborne laser scanner. Points are classified as to their altitude similarity and adjacency with other classified points, and point searching range for the classification is restricted within some number of scan-lines, preventing classification speed from lowering as the process goes on. Besides, we detected wrong discrimination of one object into more than two classes, then integrated them into a single class. Consequently we could discriminate points of each building from others, its annexes and none building points simultaneously.

This paper serves to analyze discourses on concubine at the beginning of the modernization era or during the enlightenment period of Korea. For this analysis, the estimated time frame of the enlightenment period will be from 1860 through the time when Korea was annexed into Japan, which was in 1910. The discourses appeared in newspapers and Shinsoseol which are the text of this study have been analyzed with the qualitative research technique. The major conclusions that are derived from the study are as follows: First, intellectuals during enlightenment period of Korea, criticizing concubinage, tired to establish the monogamous relationship and they argued that it should be the prior condition for Korea to enter into the civilized society. Second, the concubinage was criticized in the point of the newly established view. The criticism was on double sex ethics, applying different ethical standards to men and women and the prohibition of wifes jealousy of concubine. Third, intellectuals during enlightenment period of Korea were tried to do away with concubinage by enforcing the discrimination between wife and concubine. But the efforts resulted in making concubinage personal problems. Also consciousness based confucian ethics including female virtues was forced to be followed in ordinary affairs while concubinage was criticized in the point of the view of western ethics based consciousness. The huge differences between two ethics consciousness resulted in serious conflicts in family.

Purpose : To assess the clinical results of second toe-to-finger transfer in traumatic amputated index finger. Materials and Methods : For the clinical evaluation, we have analyzed 12 patients with ROM of finger joints, pinch power, static two point discrimination, life functional assessment, and patient's satisfaction. Results : In genral ROM was $54.4^{\circ}$ at MP joint, $17^{\circ}$ at PIP joint and $6.7^{\circ}$ at DIP joint. Pinch power was good in 3 cases, fair in 7 cases, and poor in 2 cases. Daily life activity and patient's acceptance were satisfactory. Conclusion : Although transfered toe function may be poorer than normal finger, the hand was restored to a useful, sensate and versatile functional unit.

We studied the results of the immediate microsurgical reconstruction of the distal digit injury with short vascular pedicled partial toe transfer. Thirteen patients with amputation or crush injury of the distal digit who underwent partial toe transfer at the authors' institute over 8-year period were reviewed. Delay between initial injury and reconstruction ranged from 1 to 9 days. All flaps were harvested on a short vascular pedicle, with anastomoses performed at a proximal interphalangeal joint level on the fingers and metacarpophalangeal joint level on the thumbs. Good to excellent cosmetic and functional results were obtained in all cases, with nearly normal-looking fingertip. The mean static two point discrimination was 10 mm. Immediate reconstruction with short vascular pedicled partial toe transfer is an excellent option for the reconstruction of the compostie defect of the distal digit.

Reverse digital artery flaps were performed successfully to resurface the fingertip defect in 13 patients as noninnervated pattern and in 12 patients as innervated pattern from March 1993 to February 1996. No loss of flap in this series was noted. Refinements in flap design and surgical technique resulted in favourable functional and ethetic results. The average two-point discrimination of the reconstructed fingertip was 7.2mm and 4.5mm in the noninnervated and innervated flaps, respectively. This flap is an one of the ideal and reliable option for reconstruction of fingertip defects.

The purpose of this research is to go beyond the policy support of the traditional sixth industry and to build a business model of the farmers' business by establishing the business model of the establishment of the sixth industry utilizing agricultural products of individual farmers. First, we defined the business model of the 6th agricultural industry, and secondly set up two models via FGI based on the 9 block model of BMC (Business Model Canvas), and applied feasibility, cost appropriate, differentiation point Through the establishment of hard-working business, sales consolidation, consumer-centric model set. Third, using the Delphi method in each area of 9 Block, the final 21 components were set. Through this BMC model, it was shown that discrimination and accessibility are important factors in the 6th agricultural field foundation business model.

Introduction: This study evaluated nerve recovery through retrospective study of patients with lingual nerve damage. Patients and Methods: The patients who visited Seoul National University Dental Hospital for an injury to the lingual nerve from April 1988 to August 2009 were enrolled in this study (n=41). The relevance of various factors including the causes of damage, age, etc. was analyzed by the subjective improvement based upon questionnaires and the clinical records. The evaluation variants were a subjective assessment and neurosensory examination composed of the direction, contact threshold, two-point discrimination, pin prick, thermal discrimination and current perception threshold. Results: The causes of lingual nerve damage were an extraction of the lower third molar (75.6%), local anesthesia (9.7%), incision and drainage (4.88%), trauma (2.44%). The evaluation of subjective prognosis exhibited no difference in sensory improvement depending on the cause, age and gender. Based upon the subjective evaluation, 44.7% of patients showed sensory improvement. The first hospital visit from injury was shorter in the group showing subjective improvement (3.41 months) than those showing no improvement (5.24 months) (P=0.301). Thirty six out of 41 patients were treated with only conservative therapy and 5 patients were treated by surgical intervention. Neurosensory examinations revealed improvement, although not statistically significant, and the degree was higher in the subjectively improved group. The contact threshold discrimination showed the highest correlation with subjective improvement (P=0.069). Most of the sensory recovery was gained within 12 months and the degree of improvement at the tip of the tongue was higher than that of the dorsum (P<0.001). Conclusion: The damaged lingual nerve improved at a rate of 44.7% and mostly within 12 months after the incident. There was no difference between the subjective prognosis and neurosensory examination depending on the cause of damage, age and gender, whereas the contact threshold discrimination was the best variant that reflected the subjective prognosis statistically.

In 1980 Morrison and O'Brien reported their experiences about the reconstruction of amputated thumb using wrap-around neurovascular free flap from the great toe with a nonvascularized iliac bone graft. From then it has been considered to be a good reconstructive procedure for the amputated thumb, but it's indication has been limited distal to the metacarpophalangeal(MP) joint. We have performed 37 cases of wrap-around free flap from the great toe for the reconstruction of thumb amputated at distal or proximal to the MP joint and investigated their functional results according to the level of amputation. Level of amputation was distal to the MP joint in 25 cases and proximal to it in 12 cases. Pinching and grasping power, two point discrimination and the amount of opposition to the other fingers were compared to the uninjured hand. Pinching and grasping power were not significantly different according to the level of amputation but the amount of two point discrimination was significantly high in the cases amputated proximal to the MP joint. The opposition of reconstructed thumb to the other fingers was completely possible in all cases amputated distal to the MP joint. In 12 cases amputated proximal to the MP joint of the thumb, opposition was completely possible in 6 cases in which the iliac bone block was fixated in the position of $30^{\circ}$ flexion and $45^{\circ}$ internal rotation but in 6 cases in the fixation of $30^{\circ}$ flexion and $30^{\circ}$ internal rotation, the opposition of reconstructed thumb to the ring and little fingers were impossible in 5 cases and only to the little finger in 1 case. In this study, we concluded that even if amputation proximal to the MP joint, it is no more contraindication of the wrap-around free flap procedure for thumb reconstruction, however in these cases we recommend iliac bone block fixation in the position of $30^{\circ}$ flexion and $45^{\circ}$ infernal rotation for the better functional outcome.

Objective : This study aimed to establish an analytic methodology that can objectively evaluate the proverb comprehension levels that vary based on the aging process. Method : This study recruited 70 normal elderly aged ≥ 65 years and performed proverb comprehension tasks using an explanation method. A scoring estimation method was designed on 3 and 5-point scales. The difficulty and discrimination levels were calculated based on the two scales, thereby selecting the final questions and evaluation scale. Results : First, the item discrimination index on the 5-point scale was relatively higher than that on the 3-point scale, and 10 items were finally selected. Second, in terms of proverb comprehension ability, the elderly group aged 70 ~ 84 years showed significantly lower performance than those aged 65 ~ 69 years. Additionally, subjects with ≥ 10 years of education showed significantly higher performance than those with 9 ≤ years of education. Third, the performance of the proverbs comprehension task negatively correlated with the reaction time of the executive function task. Conclusion : Proverb comprehension is a task that can distinctively show a deterioration of brain functions in line with the aging process even among the normal elderly group and therefore, can estimate the difference more effectively with an increase in the score of the evaluation scale.
