Background Although the conventional direct brow lift operation provides a simple means of managing lateral brow ptosis, the scars produced have been unacceptable. However, using the modifications proposed here, scarring showed remarkable improvement. This article reviews our experiences with the presented technique, mainly with respect to postoperative scarring. Methods Measured amounts of supra-eyebrow skin and subcutaneous fat were excised en bloc in the conventional manner under 'hyper-hydrated' local infiltration anesthesia. The lower flap and the edge of the upper flap were undermined above the muscular plane, and the orbicularis oculi muscle was directly suture-plicated and suspended upward to the distal frontalis muscle. Skin closure was performed in a basic plastic surgical manner. Results From April 2007 to April 2012, a consecutive series of 60 patients underwent surgery using the above method. The average width of the excised skin was 8 mm (range, 5-15 mm) at the apex of the eyebrow. Preoperative complaints were resolved without occurrence of significant complications. The surgical scars showed remarkable improvement and were negligible in the majority of the cases. Conclusions The direct brow lift operation combined with plication/suspension of the superior and lateral portion of the orbicularis oculi muscle provides a simple, safe, and predictable means of correcting lateral brow ptosis. The scars were acceptable to all of the patients. For proper management of the frontalis tone, upper blepharoplasty and/or repair of eyelid levator function must be considered in addition to brow lift procedures.

Background The forehead, which occupies about one third of the face, is one of the major determinants of a feminine or masculine look. Various methods have been used for the augmentation of the forehead using autologous fat grafts or alloplastic materials. Methylmethacrylate (MMA) is the most appropriate material for augmentation of the forehead, and we have used an injection-molding technique with MMA to achieve satisfactory results. Methods Under local anesthesia with intravenous (IV) sedation, an incision was made on the scalp and a meticulous and delicate subperiosteal dissection was then performed. MMA monomers and polymers were mixed, the dough was injected into the space created, and manual molding was performed along with direct inspection. This surgery was indicated for patients who wanted to correct an unattractive appearance by forehead augmentation. Every patient in this study visited our clinics 3 months after surgery to evaluate the results. We judged the postoperative results in terms of re-operation rates caused by the dissatisfaction of the patients and complications. Results During a 13-year period, 516 patients underwent forehead augmentation with MMA. With the injection-molding technique, the inner surface of the MMA implant is positioned close to the underlying frontal bone, which minimizes the gap between the implant and bone. The borders of the implant should be tapered sufficiently until no longer palpable or visible. Only 28 patients (5.4%) underwent a re-operation due to an undesirable postoperative appearance. Conclusions The injection-molding technique using MMA is a simple, safe, and ideal method for the augmentation of the forehead.

Treatment of esophageal perforation when diagnosed late remains controversial. Ten consecutive patients since 1990 were treated late(later than 24 hours) for esophageal perforation with primary repair. Four perforations were iatrogenic, 3 were spontaneous, 2 were foreign body aspiraton and 1 was trauma. The interval from perforation to operation was 116 hours in mean and 48 hours in median value. The principles of repair included (1) a local esophagomyotomy proximal and distal to the tear to expose the mucosal defect and intact mucosa beyond, (2) debridement of the mucosal defect and closure, (3) reapproximation of the muscle, and (4) adequate drainage. The repair was buttressed with parietal pleura or pericardial fat in 9 patients. Associated distal obstruction was treated with dilation and esophagomyotomy intraoperatively. There was one mortality and cause of death was massive gastric bleeding due to gastric ulcer on 33rd day after operation. Five patients had leak at the site of repair and these cases were treated completely with conservative treatment except a mortality case. In conclusion, in the absence of malignant or irreversible distal obstruction, meticulous repair of perforated esophagus and adequate drainage are preferred approach, regardless of the duration from the injury to the operation.

Mediastinal lipoblastoma is a rare benign tumor originating from embryonic lipid cells and it almost always occurs during infanthood or early childhood. It is a tumor with a good prognosis despite its potential for local invasion and rapid growth. We report here on a three years old girl who was treated for a benign lipoblastoma in the anterior mediastinum. CT scanning showed a fat containing mass without internal calcification or fluid component, and the mass showed a compressive effect on the adjacent structures. The mass was located between the pericardium and right mediastinal pleura and it was removed completely without complication. Pathologic examination revealed a benign lipoblastoma. The patient showed no evidence of recurrence at the time of the report.

A total of 800 one-day-old chickens (Cobb 500) were obtained from a local hatchery and allocated randomly to five dietary treatments. This study conducted for 42 d. Treatment groups included 1) CON (control), 2) T0.3 (0.3% of thyme extract), 3) T0.6 (0.6% of thyme extract), 4) G0.3 (0.3% of garlic extract) and 5) G0.6 (0.6% of garlic extract). Thyme extract included $90{\mu}g/ml$ Carvacrol and 400 mg/ml thymol while garlic extract included 100 mg/ml elastin. There were no significant effects among the treatments on weight gain, feed intake and feed conversion ratio over the entire trial. Also, no significant differences were observed between CON group and other treatments in plasma parameters (cholesterol, triglyceride and HDL) and hematocrit. Sex of chickens had no effect on blood parameters. Supplementation of herb extracts did not affect carcass characteristics including carcass yield, breast, thigh and abdominal fat. There were no significant differences observed in carcass characteristics between males and females fed with different levels of herb extracts. In conclusion, supplementation of garlic and thyme extracts as feed additives at two levels of 3 and 6% in the present study did not improve performance and carcass traits of broiler chicks.

The principal objective of this study was to determine the importance of obesity management nutrition programs for obese male workers after performing a 10-week nutrition program and to compare changes in the obesity index, health behavior, meal intake, and blood constituents. The study subjects included 44 individuals, all without chronic disease. After the program, the weight, body mass index (BMI), body fat percentage, and waist-hip ratio (WHR) of the subjects dropped. Dietary life behavior scores increased. In particular, more than 30% increases were detected in self-control of surfeit, control of eating speed, temperance, and regular exercise items. Total caloric intake and average drinking intake dropped. Though insignificant, systolic pressure, total cholesterol, LDL-cholesterol, and sGPT all dropped as compared to the levels measured prior to the program. Fasting blood sucrose, triglyceride, $\gamma$-GTP, and atherogenic index dropped significantly. HDL-cholesterol, though insignificant, increased. As the result of examining correlations between the subjects' health life behavior, caloric intake, and improvement in obesity, we noted a significant correlation between self-control of surfeit and temperance in the health life behavior item, along with significant correlations among total calorie intake, surfeit percentage, and daily average drinking intake. These results demonstrated that nutrition program for obese workers performed at the Community Health Center had the effect of reducing obesity, improving health behavior, and improving clinical levels. Thus, it is advisable that obesity management programs be achieved, linking the center of local societies' health promotion projects, community health centers, and workplaces, and various programs should be developed to maintain and continue changes in workers' behaviors, such that the positive effects of improvement in obesity could be maintained, even after the program.

Since obesity has been a crucial issue regarding children's health in Korea, numerous studies have been conducted. However, it is difficult to locate studies that can help researchers and/or medical professionals who want to study behavioral differences between obese and normal weight (non-obese) children. The collected literature about obese childrens behaviors were accumulated by performing 'key word' searches from several web engines: 'obesity' 'children obesity' 'behavior' 'habit' 'eating behavior or habit' 'exercise' 'physical activity' and 'daily behavior'. The information was extracted and the behaviors were reviewed utilizing 30 papers that revealed any differences from normal weight children with at least p .05 level of significance. According to those studies, the obese children tended to skip meals more often as a method of losing weight. They also have an increased appetite, eat larger portions and rarely leave food on their plates. The obese children prefer to eat high fat, high calorie foods and eat faster than their normal weight counterparts. Also, the children usually eat alone and eat at irregular meal times. Beside the behaviors related to the standard three meals a day, obese children have high preferences for snacking. The children reported that with pocket money they usually eat certain types of snacks without parent approval. The children stated that they exercise more on a regular basis. However, when asked about their participation they were not likely to engage actively. Meanwhile, they tend to spend free time doing sedentary activities such as watching TV or playing on the computer. Since these studies used self -reported questionnaires with a small sample, size there may be difficulty in forming a basis about obese children's behaviors. Nevertheless, these findings are in accordance with other studies conducted in local as well as western countries. In conclusion, obese children have different daily behaviors or routines from normal weight children. It is recommended that altering these behavioral patterns to match those of normal weight children should be encouraged.

A deep understanding of the dietary patterns and nutrient intake is important for assessment of possilbe nutritional risk and for establishing nutrition improvement strategies. This study was conducted toexamine the dietary characteristics of a nutritionally poor elderly group compared to the middle-and highly-nourished group. Elderly participant was recruited from local elderly centers in Suwon city in 1998. Trained dietitians interviewed 119 elderly(35 males, 84 females) aged 60 years and over for collecting dietary data(24-hour recall) and related variables. Male and female subjects were grouped into high, middle, and low according to the mean nutrient adequancy ratio(MAR) tertiles. An analysisof the percentage of RDA(Recommended Daily Allowances of Korea) for each of the 10 nutrients showed that the male low-MAR group consumed below the RDA in all kinds of nutrients, and the female low-MAR group consumed nutrients below the RDA except vitamin C. An evaluation of nutrient density by Index of Nutritonal Quality(INQ) also showed a similar tendency. Thus, the INQ level of the male low-MAR group was significantly lower than the middle-or high-MAR group, especially in protein, vitamin A, thiamin, riboflavin, and phosphorus(p<0.05). Moreover, INQ level of female low-MAR group was significantly lower than that of the high group(p<0.05) in all nutrients. The female low-MAR group's daily food intake were also lower than those of the high-MARgroup in gains, fish, fruits, oil and beverages. The energy distribution from carbohydrates, fats and proteins showed that the male low-MAR group had significantly higher carbohydrate and lower fat proportions compared to each gender high-MAR group, respectively. The male and female low-MAR group had low scores about eating all side dishes. These findings indicate that a moderate increase of the meat/egg/fishes intake was needed by the male low-MAR group for improving nutrition adequacy, and an overall increase of the food quantity and quality was desired for the female low-MAR group. These data could be used for planning a community elderly nutrition program and establishing strategies for tailored guidelines for the individuals.

This study was conducted to evaluate meat quality traits, proximate composition, fatty acid profile and sensory attributes of pork produced under free-range and semi-intensive pig rearing systems. Longissimus dorsi muscles from pork carcasses were taken just after the slaughtering of finishing pigs reared under semi-intensive and free-range systems to test the meat quality parameters (pH, color, water holding capacity, and cooking loss), proximate composition (moisture, protein, fat, and ash) and fatty acid profile. Furthermore, the organoleptic properties were evaluated using 30 untrained panelists. The results revealed that the system of rearing did not affect (p > 0.05) the proximate composition, water holding capacity, color, pH and cooking loss of pork along with the fatty acid composition except for vaccenic acid (p < 0.05). The monounsaturated fatty acid (MUFA) content was affected (p < 0.05) by the rearing system while no effects were observed on the unsaturated fatty acid: saturated fatty acid ratio and omega-six to omega-three fatty acids ratios (p > 0.05). No difference was observed (p > 0.05) concerning the sensory attributes although pork obtained from the free-range system had the highest scores. In conclusion, the system of rearing did not show a significant effect on the meat quality parameters, composition and sensory attributes of pork obtained from cross-bred pigs.

Ruspolia differens (Serville) (Orthoptera: Tettigoniidae) is a highly valued edible grasshopper species in Africa. However, the effects of plant diets on lipid content and fatty acid composition of R. differens are not well understood. We tested the effects of four diets on the total lipid content and fatty acid composition of R. differens. Sixth instar nymphs of R. differens were reared on one, and mixtures of two, three, and six natural plant inflorescences. Individuals collected from the field constituted a control treatment. We extracted lipids and analyzed the fatty acid methyl esters using gas chromatography-mass spectrometry. We analyzed if the total lipid content, body weight, and fatty acid composition differed among diets and between the sexes using two-way ANOVAs and a PERMANOVA model, respectively. The total lipid content and weight of R. differens did not differ among the diets. The nine common fatty acids were palmitic (mean across treatments, 26%), oleic (22%), palmitoleic (18%), linoleic (13%), stearic (7%), myristic (6%), myristoleic (4%), ${\alpha}$-linolenic (2%) and arachidic acid (1%). The composition of fatty acids and the proportion of essential fatty acids significantly differed among the diets. The proportion of essential fatty acids was highest in the control treatment (21%) but low in less diversified (one to three feed) diets (12-13%). This study demonstrates that the fatty acid composition in R. differens can be influenced through diet. Thus, with dietary manipulations, using local plants in Africa, it is possible to produce R. differens with preferred high quality essential fatty acids for human consumption.
