  • Purpose: This study was conducted for analysis of menu pattern and food diversity of snack menus of child care centers in order to provide preliminary data for establishment of related guidelines for snack menus for child care centers. Methods: Data from 630 snack menus (350 for morning snacks and 280 for afternoon snacks) of March, 2013 from 14 Child Care Information Centers in Seoul provided for child care centers were analyzed. In addition, the menu pattern and food diversity of morning snack menus were compared with those of afternoon snack menus. Results: Differences in menu pattern and food diversity were observed between morning and afternoon snack menus. The majority of snack menus (66.8%) included two menu items and the numbers of menu items of afternoon snack menus were significantly larger than those of morning snack menus. The percentages of "Grains (G)" and "Grains (G) + Milk (D)" patterns were higher in snack menu (G: 18.9%, G+D: 17.1%). Approximately one third of snack menus were composed of only one food group. In addition, 45.6 % of all snack menus comprised milk and only 23.0% included fruits. Conclusion: These results demonstrated the need for improvement in food composition and diversity of snack menus provided by Child Care Information Centers for child care centers. Therefore, to ensure children's intake of nutritionally balanced snacks, it will be necessary to establish more detailed guidelines for the menu pattern and food composition in snack menus for child care centers.

  • The red algal genus Chondrus have long been used as raw materials for carrageenan and dietary fiber in health foods. Despite the importance of genetic information in safeguarding natural seaweed resources, knowledge of the population genetics of Chondrus in the northwest Pacific is limited. In this study, genetic diversity and phylogeographic structure of 45 populations (777 specimens) of Chondrus from Korea, China, and Japan were evaluated based on mitochondrial COI-5P gene sequences, and phylogenetic relationships were confirmed based on plastid rbcL gene sequences. Molecular analyses assigned the specimens in this study to three Chondrus species: C. nipponicus, C. ocellatus, and C. giganteus; phenotype-based species classification was impossible owing to their high morphological plasticity. We found moderate intraspecific genetic diversity and a shallow phylogeographic structure in both for C. nipponicus and C. ocellatus, and low intraspecific genetic diversity in C. giganteus. Each of the three species exhibited high-level intraspecific gene flow among regions based on the most common haplotypes (CN1 for C. nipponicus, CO1 for C. ocellatus, and CG1 for C. giganteus). Our comprehensive genetic information provides insights into the phylogeographic patterns and intraspecific diversity of the economically important Chondrus species. It also highlights the need to conserve existing natural Chondrus resources through continuous monitoring of genetic diversity and phylogeographic pattern.

  • This study comparatively analyzed the instrumentation and the voicing structure, which were shown in the film music titled "Star Wars-Main Title" by John Williams(1932~), with analytical technique that the writer mapped out, and aimed to discover the progression principle in orchestration based on the results. Also, it applied a functional part-division method that was classified and distributed into 3 functional parts according to auditory cognitive level as for each of functional elements such as the musical element. And, it made it pattern for the vertical structure and the voicing structure in musical instruments, which were distributed to each functional part based on this, and comparatively analyzed the standard point in a change which were shown according to progression of music, namely, the operating technique. As for the results of this study, first, each theme has specific instrumentation pattern. Unity was emphasized by consistently organizing those things in exposition, reprise, and recapitulation of each theme. To reinforce diversity, an attempt was made such as adding and reducing auxiliary instruments in the middle part and the rear part. Second, even in a change of instrumentation pattern by passage in accordance with a change in theme amid each part, the same instrumental group was organized in the middle part, thereby having maintained unity. Third, to strengthen diversity by clause, which is forming each theme, a continuous change in voicing pattern was created by adding or omitting a part. Fourth, the voicing concentration was maintained the structure of "thinness-thickness" in the whole musical piece. However, in part 2 that is repeated theme 3, diversity was pursued with a unique change of "thickness-thickness." Fifth, in part 4 that is indicated theme 4, the other diversity was intensified with the inverted range in the front part and the middle part. Accordingly, based on the conclusions that were indicated in this work, it is desired to be conducive to understanding the horizontal consideration and the progression principle of orchestration.

  • This study attempted to estimate the dietary quality and the food diversity by analyzing the military foodservice menu. To evaluate the dietary quality, an analysis of NAR(Nutrient Adequacy Ratio) and MAR(Mean Adequacy Ratio) were carried out. DDS(Dietary Diversity Score), DVS(Dietary Variety Score) and DMGFV(Dairy Product, Meat, Grain, Fruit, Vegetable group) were used for assessment of food diversity. A Can-pro 3.0 and an excel were used for dietary data analysis and SPSS 12.0 program was used for statistical analysis. The results were as follows. The NAR of the 9 nutrients was above the RDAs and MAR was $1.71{\pm}0.19$. For 19 days(61.3%), DDS was 5 and for 12 days(38.7%), DDS was 4. The average of DDS was $4.6{\pm}0.25$. The Fruit & vegetable groups were not often served compared to other groups and especially fresh fruit were not given enough. The average of DVS and DVSS were $22.48{\pm}0.61$ and $29.26{\pm}0.66$ each. The most frequent food pattern was 'DMGFV=11111' which was served for 19 days(61.3%) and second frequent pattern 'DMGFV=11101' was served for 12 days(38.7%). DDS was significantly associated with Vit. C intake and DVS and DVSS was significantly related to Vit. $B_1$ and Vit. $B_2$ intakes. The MAR was significantly correlated with only DVSS. It could be interpreted that DVSS is a useful parameter for evaluating nutrient intakes as previous studies verified. Based on these findings, it can be said that military foodservice was provided with adequate nutrition and diversity. Menu was well composed of various foods which met the nutrition standards, but should provide more fresh fruits for adequate provision of vitamins and minerals.

  • Pine (Pinus densiflora) forests of 315 sites were classified by applying the phytosociological method, TWINSPAN and DCA (detrended correspondence analysis). The floristic composition and diversity patterns of the vegetation types analyzed and documented. The vegetation types were classified 8 groups including 4 groups of Quercus mongolica type and 4 groups of Quercus serrata-Smilax china type. Taxonomically, Compositae was the most diverse family (21 genus, 45 species) and followed in order of Liliaceae (18 genus, 34 species), Rosaceae (17 genus, 34 species), and Leguminosae (15 genus, 25 species). The patterns of species richness, diveristy and evenness were significantly different among the vegetation types. In altitudinal pattern of species diversity, species richness monotonically decreased but species evenness increased with increasing altitude.

  • In this paper, we fabricated dual polarization microstrip array antenna to analyze the performance of polarization diversity of each antennas beamwidth and recommend suitable polarizations diversity antenna under indoor environments. The proposed antennas which have directional beam patterns are small, light and thin. Also they are $1\times4$ array and $4\times4$ array antenna with $70^{\circ}$, $20^{\circ}$ beamwidth, respectively. The center frequency is 1890 MHz, IMT-2000's frequency. We also measured the antennas characteristics of each beamwidth in various waveguide structured corridor and compared then with the case of space diversity using the dipole antenna. The measurement shows that the polarization diversity using directional dual polarization microstrip array antennas has more 1~7 dB diversity gain than the space diversity using the dipole antenna. Therefore, the proposed antennas are expected to be efficiently used for the design of optimal directional beam pattern antenna and diversity system for indoor environments.

  • Generally, the training set of maximum $m{\times}L(m+f)$ patterns in the pattern recognition method is required for the real-time bus reconfiguration strategy when a main transformer fault occurs in the distribution substation. Accordingly, to make the application of pattern recognition method possible, the size of the training set must be reduced as efficient level. This Paper proposes a methodology which obtains the minimized training set by applying the pattern clustering method to load patterns of the main transformers and feeders during selected period and to obtain bus reconfiguration strategy based on it. The MaxMin distance clustering algorithm is adopted as the pattern clustering method. The proposed method reduces greatly the number of load patterns to be trained and obtain the satisfactory pattern matching success rate because that it generates the typical pattern clusters by appling the pattern clustering method to load patterns of the main transformers and feeders during selected period. The proposed strategy is designed and implemented in Visual C++ MFC. Finally, availability and accuracy of the proposed methodology and the design is verified from diversity simulation reviews for typical distribution substation.

  • The purpose of this study was to find a system and a progression principle in orchestral piece based on the outcome after comparatively analyzing the orchestral operation technique in "Battle for The Glory" out of the background music in the animation "Dragon Quest IV" by Koichi Sugiyama(1931~), who is a leading runner of Japan's animation music, based on functional parts daccord & Instrumentation Pattern, Rhythm Pattern, Voicing Pattern, and harmonic ratio by progression section devised by the writer. As a result, first, five themes in this music have specific instrumentation pattern, respectively. In a passage that is shown exposition, reprise, and representation in theme, the unity was emphasized by maintaining the same instrumentation pattern. On the contrary to this, a passage of being suggested new theme is being used the exchange method and addition & subtraction in musical instrument in order to strengthen diversity. Second, the voicing pattern is forming the vertical contrasting relationship of "thinness-thickness" on the whole. However, the diversity is being intensified that is changed into the structure of "thickness-thinness" in the third theme and of "thinness-thickness" that has two melodies in the fourth theme. Third, the rhythm pattern is forming the vertical contrasting relationship of "big-small" on the whole. However, the fifth theme is being given diversity with being changed into the structure of "small-big." Fourth, the harmony by progression section from the horizontal perspective is shown to be high in the proportion of unity in the section of being repeated and represented the theme and to be high in the proportion of diversity in the section of being suggested new theme. In this study, the balanced orchestral operation technique through the operation technique, which was used in this work, is what extracts the relationship of diverse proportions in the horizontal progression section based on the technique of vertical perspective. In this aspect, this analytical study is desired to be positioned as a new paradigm in establishing a theoretical system and an educational method in orchestration.

  • Classifying the diverse and complex clothing category of nationality subcultures in China is not a simple task. However, summing up, it can be largely classified that clothing of the northern area is long trousers and short skirt. Among the clothing of Nationality in China, especially, Pao(robe: 袍) has its diversity and colorfulness. whose elements forming its each characteristic feature has enough value to be investigated fully in the historical point of view. The conclusions of this study reveals that Pao in nationality subculture in China can possibly be divided into the four types as Qipao(旗袍) in Dongpei area, Mongopao(蒙古袍) in Inner Mongolia, Qiapan in Xinjiang area, and Zangpao in Tibet area. The modes of Qipao and Mongopao are mainly similar in that they have diagonally on the right, stand collar in composition, but Qipao shows its diversity in collar and slashes, and Mongopao also shows diversity in its colare and waistband. Since western culture flowed into China along with its open door and reform policy, the splendid color and distinctive pattern, decoration, diversified method of compositions and clothing categories of Nationality cultures are disappearing in its their originality and nationality.

  • This paper proposes a new multicarrier code division multiple access (CDMA) system. The proposed multicarrier CDMA system provides the advantages that the transmission bandwidth is more efficiently utilized by using divided spreading sequence, time and frequency diversity is achieved in frequency selective nultipath (acting channel, and inter-carrier interference (ICI) can be minimized by using specific data and code pattern. In this system, transmitted data bits are serial-to-parallel converted to some parallel branches. On each branch each bit is direct-sequence spread-spectrum modulated by divided spreading sequences and transmitted using orthogonal carriers. The receiver providers a Rake for each carrier, and the outputs of Rakes are combined to get time and frequency diversity. This multicarrier CDMA system allows additional flexibility in the choice of system parameters. Upon varying system parameters, bit error rate (BER) performance is examined for the proposed multicarrier CDMA system. Simulation results show that the proposed multicarrier CDMA scheme can achieve better performance than the other types of conventional multicarrier CDMA systems.
