This study investigated the use and understanding of food and nutrition labels in 498 female adolescents (middle school students: MS 248, high school students: HS 250) in Gyeonggi-do. Fifty percent of the MS and 47.2% of the HS read food labels, and the most common reasons for reading labels were to find a product's expiration date and price. The food label information considered most important by the subjects was the name of the manufacturing company and expiration date. Over 80% of the subjects read nutrition labels. The MS read nutrition labels to find nutrients and their amounts in foods, while the HS read labels mostly in an effort to control body weight. These subjects gave more attention to calories and fat, the nutrients related to body weight, than to other nutrients. The subjects were highly aware of the necessity and positive effects of nutrition labels, because they believed labels could make it easier for them to choose healthy foods. However, scores for understanding nutrition labels showed the subjects failed to understand label information accurately. Generally, the MS showed better dietary behaviors than HS. But the HS had significantly higher scores than MS for the item "know relative weight with height." Those that read food labels had significantly better BMIs, dietary behaviors, and awareness and understanding of nutrition labels. There were significant positive relationships among awareness & understanding of nutrition labels and subjects' dietary behaviors. The study findings can be utilized to better plan nutrition education programs aiming to improve use and awareness of food and nutrition labels among adolescents.

There is a growing consumer preference for self-medication, which has resulted in the growth of the Korean functional food market to \1.5 trillion in 2014. Functional foods that can modulate immune responses and enhance liver health are in the top 2 product-specific health functional food categories. The aim of this project was to develop and commercialize new health functional foods incorporated with Cordyceps militaris. Cordyceps genus includes about 400 species, many of which have been used as traditional medicines for many years in Asian countries. C. militaris belongs to the class Ascomycetes and has been used extensively as a crude drug and tonic food in East Asia. Owing to the various physiological activities of its main active constituent, cordyceptin, C. militaris is currently being used for multiple medicinal purposes. Recently, many studies have tried to elucidate the pharmacological mechanisms underlying the activities of Cordyceps spp., which include immune activation, anti-inflammatory, anticancer, and antiviral effects. After continuous attempts and research toward industrialization, C. militaris cultivated using brown rice was developed into a product by a standardized process and mass-cultivating system. It was successfully introduced into the market and was approved as a functional food ingredient for the first time in Korea. Based on this information, C. militaris containing functional food product for strengthening the immune system was released in August 2014 under the brand name "Dongchoong Ilgi." Dongchoong Ilgi is potentially beneficial for improving immune and liver functions and may enhance both the convenience and effectiveness of health functional foods taken by healthy people and patients with minor illness. In addition, the results of our study may be applicable for the development of health functional foods that could lower the risk of diseases such as the common cold and cancer.

The objective of this research is to identify and examine the punk hair styles which, with their various, rather vague names, help to describe the twentieth century subordinate culture or subculture and also their place today as one of the mainstream male hair trends. The scope of this research will stretch to include also: North-east and around that areas native Americans'hair styles which, are thought to have strong links with the Punk hair tend. The focus of this research will remain with the so-called Mohican or Mohawk hair styles(collectively referred to as Punk styles), which have originated mainly from native American warrions residing in North-east and South-east region of the United States. This study clarified a few questions in doubt concerning the origin of cockcomb hairstyle. Firstly, the cockcomb hairstyle known to represent punk hairstyle was influenced the American Indian's Roach style. Secondly, since Roach style is referred as Mohawk tribe's hairstyle in some refernces, the view of seeing cockcomb hairstyle as a Mohawk style is considered more persuasive. Thirdly, although Roach style was a usual hairstyle through North-east and South-east region of the United States, the people in South-east region did Roach hair style because of the North-east's influences. Lastly alike the Punkers had several kinds of cockcomb hairstyle. American Indians'Roach style also differed in shape concerning of their regions and their kindred. In addition, the reason why the most common term to refer punk hairstyle became Mohican is considered as that the film 'Last Mohican' has influenced on it. That film can appeal their history and play a good role of mediator to let the public know better about themselves, 'Mohican' naturally became the name of the specific hair style.

Model updating method is known to the area to correct finite element models by the results of the experimental modal analysis. Most common methods in model updating depend on a parametric model of the structure. In this case, the number of parameters is normally smaller than that of modal data obtained from an experiment. In order to overcome this limitation, many researchers are trying to get modal data as many as possible to date. 1 want to name this method multiple modified-system generation method. These Methods consist of direct system modification method and feedback controller method. The direct system modification Is to add a mass or stiffness on the original structure or perturb the boundary conditions. The feedback controller method is to make the closed food system with sensor and actuator so as to get the closed loop modal data. In this paper, we need to focus on the feedback controller method because of its simplicity. Several methods related the feedback controller methods are virtual passive controller (VPC) sensitivity enhancement controller (SEC) and mode decoupling controller (MDC). Among them, we will apply MDC to the model updating problem. MDC has various advantages compared with other controllers, such as VPC and SEC. To begin with, only the target mode can be changed without changing modal property of non-target modes. In addition, it is possible to fix any modes if the number of sensors is equal to that of the system modes. Finally, the required control power to achieve desired change of target mode is always lower than those of other methods such as VPC. However, MDC can make the closed loop system unstable when using incomplete modal data. So we need to take action to avoid undesirable instability from incomplete modal data. In this paper, we address the method to design the unique and robust MDD obtained from incomplete modal data. The associated simulation will be Incorporated to demonstrate the usefulness of this method.

A new Gomchwi cultivar 'Sammany' was developed by a cross between Gomchwi (Ligularia fischeri (Ledeb.) Turcz.) and Handaeri-gomchwi (Ligularia fischeri var. spiciformis Nakai). Gomchwi is a common Korean name referring wild edible plant species within Ligularia genus. 'Sammany' has purple colored petiole ears and petiole trichome is absent. It has 2nd degree leaf vein density. Plant height, leaf length, leaf width and petiole length were 46.2, 19.1, 19.5 and 32.1 cm, respectively. Plant height was higher than 'Gondalbi'. Bolting occurred in mid. July and it flowered from late August to early September. 'Gondalbi' bolted and flowered 26 days earlier than 'Sammany', and consequently has earlier flowering time more than 26 day. Leaf number of 'Sammany' was 156 per plant but 'Gondalbi' had 130. 'Sammany' had thicker leaves (0.61 mm) compared to 'Gondalbi' (0.46 mm). As a result, yield was higher in 'Sammany (1,077 g/plant)' than 'Gondalbi (798 g/plant)' and leaf hardness was lower in 'Sammany ($20.8kg/cm^2$)' compared to 'Gondalbi ($23.0kg/cm^2$)'. In addition, 'Sammany' was found to be moderately resistant to powdery mildew. With enhanced agronomic and pathology traits, 'Sammany' was newly registered as a new Gomchwi cultivar (variety protection no. 131 on May 2017).

A new isolate of rod-shaped virus was identified from grafted cactus, Gymnocalycium mihanovichii grafted onto Hylocereus trigonus, in Korea. The virus proved to be a new Tobamovirus and called previously as Tobamovirus-Ca for which we suggest the name Cactus mild mottle virus(CMMoV), because it produced systemic mild mosaic symptoms on its original host. CMMoV is distantly related to known species of the genus Tobamovirus on the basis of host range, serological and sequence analyses. Western blot analysis showed that CMMoV is serologically unrelated to Summons' Opuntia virus which is the only known species of the genus found in cactus plants. The 3'-terminal 2,910 nucleotides have been sequenced for the virus. The coat protein (CP) and movement protein (MP) genes encode 161 and 306 amino acids residues, respectively. The nucleotide and amino acid sequences of the CP were 39.6 ％ to 49.2 ％ and 26.4 ％ to 40.3 ％ identical to other tobamoviruses, respectively. The MP and 3' noncoding region shared 16.3 ％ to 23.3 ％ and 44.6 ％ to 63.4 ％ identities, respectively, with the members of the genus. Phylogenetic tree analysis of the CP gene revealed that CMMoV clusters with members of subgroup I of Tobamovirus. CMMoV particles contained genomic RNA along with two subgenomic RNAs, and this characteristics is common in the members of the subgroup II. This is the first information of sequence and comparative analysis of a Tobamovirus that infects cactus.

Nano and micro capsulation (NM capsulation) involve the incorporation for nanofood materials, enzymes, cells or other materials in small capsules. Since Kim D. M. (2001) showed that a new type of food called firstly the name of nanofood, which means nanotechnology for food, and the encapsulated materials can be protected from moisture, heat or other extreme conditions, thus enhancing their stability and maintaining viability applications for this nanofood technique have increased in the food. NM capsules for nanofood is also utilized to mask odours or tastes. Various techniques are employed to form the capsules, including spray drying, spray chilling or spray cooling, extrusion coating, fluidized bed coating, liposome entrapment, coacervation, inclusion complexation, centrifugal extrusion and rotational suspension separation. Each of these techniques is discussed in this review. A wide variety of nanofood is NM capsulated - flavouring agents, acids, bases, artificial sweeteners, colourants, preservatives, leavening agents, antioxidants, agents with undesirable flavours, odours and nutrients, among others. The use of NM capsulation for sweeteners such as aspartame and flavors in chewing gum is well known. Fats, starches, dextrins, alginates, protein and lipid materials can be employed as encapsulating materials. Various methods exist to release the ingredients from the capsules. Release can be site-specific, stage-specific or signaled by changes in pH, temperature, irradiation or osmotic shock. NM capsulation for the nanofood, the most common method is by solvent-activated release. The addition of water to dry beverages or cake mixes is an example. Liposomes have been applied in cheese-making, and its use in the preparation of nanofood emulsions such as spreads, margarine and mayonnaise is a developing area. Most recent developments include the NM capsulation for nanofood in the areas of controlled release, carrier materials, preparation methods and sweetener immobilization. New markets are being developed and current research is underway to reduce the high production costs and lack of food-grade materials.
