  • The objective of this study was to investigate the effects of vegetarian (lacto-ovo vegetarian) and non-vegetarian diets on dietary habits, nutrient intake, and health status. The vegan subjects were 22 children. Among them, 54.5% of the subjects had a specific religion, 36.4% had been vegetarian since weaning, and 9.1% had become vegetarian to prevent obesity or atopy. The percentages of excessive eating by the vegetarian children were lower compared to the non-vegetarian children. The rates of intake of vegetables (42.2%) and fruits and fruit juice (55.9%) by the vegetarian children were higher compared to non-vegetarian subjects. Non-vegetarian children consumed more milk, dairy products, as well as meat, fish, eggs, soybean, and tofu than the vegetarian subjects. Vegetarian children ate more bread, potato, and fruits as snacks than non-vegetarian children. Furthermore, non-vegetarian children consumed more carbonated beverages and ice cream than the vegetarian subjects (p<0.05). Generally, the subjects' energy intake was lower than standard values, and vegetarian children's calcium intake was deficient. Non-vegetarian children's fiber intake was deficient, and they consumed fat, vitamin $B_2$, calcium, and cholesterol excessively (p<0.05). Nutrition tablet intake was higher among non-vegetarian children; however, the rate of fatigue among subjects was higher among vegetarian subjects than non-vegetarian subjects. Among the vegetarian subjects, 19.6% reported that they had a cold. Consequently, for the purpose of attaining balanced physical development and growth among children, an education program that emphasizes complete diets should be prepared.

  • Dodok (Codonopsis lanceolata Bench. et Hook) root contains abundant pharmaceutical substances and is widely used as a food and a medicinal herb. To identify the major components, fermented Codonopsis lanceolata was analyzed for its chemical compositions prior to their pharmaceutical substances, which were used as the fundamental data. The contents of carbohydrate, crude protein, crude lipid and ash are 79.3%, 13.0%, 2.40% and 5.3%, respectively. The calories of fermented Codonopsis lanceolata was 390.5 kcal. Total dietary fiber was 47.4% of total carbohydrates. The protein was composed of 18 different amino acids. The contents of essential and non-essential amino acids were 8,118.18 mg and 10,913.42 mg. The K was the largest mineral followed by P, Ca and Mg, which means fermented Codonopsis lanceolata is alkali material. The contents of saturated fatty acids, monounsaturated fatty acids and polyunsaturated fatty acids were 37.76%, 3.84%, and 35.64%, respectively. Therefore, the amount of the total unsaturated fatty acid was higher than that of any other plant. The content of crude saponin in fermented Codonopsis lanceolata was 60.1 mg/g. It is expected that a follow up study on fermented Codonopsis lanceolata through development and evaluation of processed foods for their functional properties would provide useful information as a source of medicinal foods.

  • To synthesize ${\omega}$-3 and ${\omega}$-6 balanced polyunsaturated fatty acid (PUFA) oil mixture, flaxseed oil and sesame oil were mixed and their anti-oxidative and sensory characteristics analyzed. For the fatty acid composition analysis results, the ${\omega}$-3 and ${\omega}$-6 PUFA ratios of the F20S80 oil mixture (flaxseed oil 20% and sesame oil 80% oil mixture) and F10S90 (flaxseed oil 10% and sesame oil 90% oil mixture) were represented as 1 to 10 and 1 to 5 ratio for ${\omega}$-3 and ${\omega}$-6 PUFA content from 4.4% to 42.1% and 8.9% to 39.7%, respectively. Since these were within 1:4~1:10 for healthy functional ${\omega}$-3 and ${\omega}$-6 balanced PUFA oil mixtures, these oil mixtures were healthy functional oil mixtures. To analyze anti-oxidative effects, acid values were analyzed. Samples were stored at room temperature, 70% relative humidity (RH) and $45^{\circ}C$, and 70% RH for 16 weeks. The acid value between F10S90 and S100 stored at $45^{\circ}C$ and 70% RH for 16 weeks were not statistically significant. The sensory characteristics such as oxidative odor and sesame odor and taste were not statistically significant among F20S80, F10S90, and sesame S100. Sensory characteristics between F10S90 and S100 stored at $45^{\circ}C$ and 70% RH for 16 weeks were not statistically significant. In conclusion, the sensory and oxidative characteristics of F10S90 were similar to those of S100. Therefore, F10S90 oil mixture should be used as a ${\omega}$-3 and ${\omega}$-6 balanced PUFA healthy functional oil mixture with high anti-oxidative effects.

  • The objective of this study was to investigate the effects of the subjective perception to the nutrient intake and mental health of Korean adolescents by the residual method. This study was based on data from the 5th and 6th Korea National Health and Nutrition Examination Survey (2010-2014) of the 2,961 total subjects(male 1,548, female 1,413, aged 12 to 19 years). The nutrient intake was collected by using the 24 hr recall method and mental health and BMI were collected by the health interview survey and physical examination research. An analysis of the relationship between the subjective perception and BMI showed that the proportion of those with a distorted perception of their body type was the highest among adolescents with normal weight(p for trend, <.001). Especially, regarding the subjective body type, the proportion of adolescents who perceived themselves overweight was significantly higher among females as compared to that among males (p for trend, <.001). An analysis of nutrient intake status against the subjective perception showed that the group of adolescents who perceived themselves overweight had the lowest scores on the index of nutritional quality (INQ), nutritional adequacy ratio (NAR) and mean adequacy ratio (MAR) (p for trend, <.001). With respect to the daily intake of major nutrients, adolescents who perceived themselves overweight consumed the lowest amounts of total energy (p for trend, <.01) and carbohydrate (p for trend,<.001). An analysis of the mental health status of the adolescents showed that those who perceived themselves overweight had the highest levels of stress recognition and depression (p<0.01). In conclusion, the adolescents' subjective perception is associated with their nutrient intake and mental health. Therefore, some educational programs are desirable to help the adolescents to have their desirable subjective perception and to increase their satisfaction with their body type.

  • Partial oxidation, $CO_2$ reforming and the oxidative $CO_2$ reforming of $CH_4$ to produce synthesis gas over supported Ni hydrotalcite-type ($Ni_{0.5}Ca_{2.5}Al$ catalyst) catalysts were carried out and the effects of metal supports (i.e.; Mg and Ca) on the formation of a stable double-layer structure on the catalysts were evaluated. The $CH_4$ reforming stability was determined to be affected by the differences in the interaction strength between the active Ni ions and support metal ions. Only a Ni-Mg-Al composition produced a highly stable hydrotalcite-type double-layered structure; while the Ni-Ca-Al-type composition did not. Such structure provides excellent stability for the catalyst (-80% efficiency) as confirmed by the long-term $CO_2$ reforming test (-100 h), while the Ni-Ca-Al catalyst exhibited deactivation phases starting at the beginning of the reaction. The interaction strength between the active metal (Ni) and the supporting components (Mg and Al) was determined by temperature-programed reduction (TPR) analyses. The affinity was also confirmed by the TPR temperature because the Ni-Mg-Al catalyst required a higher temperature to reduce the Ni relative to the Ni-Ca-Al catalyst. The highest initial activity for synthesis gas production was observed for the $Ni_{0.5}Ca_{2.5}Al$ catalyst; however, this activity decreased quickly due to coke formation. The $Ni_{0.5}Ca_{2.5}Al$ catalyst exhibited a high reactivity and was more stable than the other catalysts because it had a higher resistance to coke formation.

  • The objective of this study was to optimize processing conditions for the production of an instant puffed rice product using response surface methodology (RSM) and contour analysis. Sensory and texture qualities, and physical properties of the puffed rice were analyzed with various processing conditions related to drying and puffing temperature, and moisture content. Preference, color intensity, cohesiveness, rehydration ratio, density and lightness of the puffed rice product significantly varied depending on the processing conditions. The responses showed high $R^2$ values (0.623, 0.852, 0.735, 0.688, and 0.790) and lack-of-fit. Rehydration ratio was found to have a negative correlation with density in the condition of drying and puffing temperature. Lightness and preference scores of the puffed rice increased as the moisture content increased. According to RSM, the preference scores were very highly related to the moisture content, and the optimum processing conditions of the puffed rice product were at $40^{\circ}C$ of drying temperature, with 11.0% of moisture content, and at $232.7^{\circ}C$ of puffing temperature.

  • Purpose: The purpose of this study was to evaluate the pain recovery pattern according to the integrity and to analyze the factors affecting the progress and level of pain postoperatively. Materials and Methods: We examined 153 patients, who were treated with arthroscopic rotator cuff repair. 101 rotator cuff tears were full-thickness tear and 52 were partial tear. The mean follow up duration was 20 months (12~30 months). We evaluated the visual analogue scale, range of motion, ASES (American Shoulder and Elbow Surgeons), and UCLA (University of California at Los Angeles) scores preoperatively and postoperatively. We analyzed the pain recovery pattern between partial and full thickness tear using Student T-test and the factors affecting the progress and level of postoperative pain using multiple regression analysis. Results: The change patterns of visual analogue scale after arthroscpoic repair were similar regardless of the tear integrity. The VAS showed a continuous decreasing pattern, but increased at first 3 weeks postoperatively and at 7 weeks postoperatively, and then, decreased thereafter. The average VAS was ${\leqq}2$ points by postoperative 3 months. The factor affecting the pain score at 3 months was related to the preoperative limitation in forward flexion ($r^2=0.377$, p=0.021). Conclusion: There was no differences of the pain recovery pattern according to the integrity, and the factor affecting the progress of postoperative pain was preoperative angle of forward elevation. So, the appropriate preoperative rehabilitation protocol that can improve motions of the shoulder joint would help to improve the level of postoperative pain and functional recovery.

  • The relationship between dietary intake and vitamin/mineral supplement usage was examined in 706 adolescent girls who were high school students. 43.8% of subjects used vitamin/mineral supplements during one year. The higher the family income and parents education level, the higher percentage of vitamin/mineral supplement usage was. But there was no significant difference between grades and scores. And vitamin/mineral supplement usage was higher int he thin and obese groups than the average weight groups. Nutrition knowledge and food habit did not affect vitamin/mineral supplement usage. Calorie intakes of vitamin/mineral supplement users and nonusers were similar. However, independent of the supplements, the diets of supplement nonusers contained significantly more dietary protein, vitamin A, vitamin $B_2$, niacin, vitamin C, and calcium than the diets of the users. A considerable portion of both the users and nonusers had dietary intakes of less than 2/3 of the Recommended Dietary Allowances for vitamin $B_1$, vitamin $B_2$, niacin, calcium, and iron. Vitamin/mineral supplement nonusers generally consumed a more vitamin, mineral from diet. Reasons for taking supplements were to take energy, advice and illness.

  • Wer wegen eines Wahldelikts zu Geldstrafe von mehr als 1 Million Won verurteilt wird, verliert nach ${\S}$ 18 Abs. 1 Satz 3, ${\S}$ 19 Satz 1, ${\S}$ 266 des Koreanischen Wahlgesetzes $f{\ddot{u}}r$ die Dauer von $f{\ddot{u}}nf$ Jahren die $F{\ddot{a}}higkeit$, ${\ddot{o}}ffentliche$ ${\ddot{A}}mter$ zu bekleiden und Rechte aus ${\ddot{o}}ffentlichen$ Wahlen. Bei Verurteilung zu Freiheitsstrafe wegen eines Wahldelikts ${\ddot{A}}mter$ sich die Dauer des Verlusts der $Amtsf{\ddot{a}}higkeit$ und des aktiven bzw. passiven Walhrechts auf 10 Jahre. Dies erfolgt kraft Gesetzes. Das $hei{\ss}t$, dass die Entscheidung ${\ddot{u}}ber$ das Ob und die Dauer des Verlusts nicht im Ermessen des Gerichts steht. Allerdings sollte $diesbez{\ddot{u}}glich$ nicht verkannt werden, dass ein deratriger Entzug von $Amtsf{\ddot{a}}higkeit$, $W{\ddot{a}}hlbarkeit$ u.s.w., mit dem eine Straftat geahndet werden soll, selber von Natur aus eine Art Strafen darstellt. Der im ${\S}$ 41 des Koreanischen StGB geregelte Strafen-Katalog $enth{\ddot{a}}lt$ $n{\ddot{a}}mlich$ eine zeitlich begrenzte Aberkennung des oben genannten ${\ddot{o}}ffentliche$n Rechtsstatus als eine Art Ehrenstrafen. Nicht einleuchtend ist, warum das Wesen der Sanktion $gem{\ddot{a}}{\ss}$ ${\S}$ 18 Abs. 1 Satz 3, ${\S}$ 19 Satz 1, ${\S}$ 266 des Koreanischen Wahlgesetzes, die den gleichen Zweck und die gleiche Rechtsfolge wie die im ${\S}$ 41 des Koreanischen StGB geregelte Ehrenstrafe hat, nicht als Strafe aufgefasst werden sollte. Handelt es sich bei der oben genannten Sanktion um eine Art Ehrenstrafen, so stellt sich die Anforderung, sie je nach der Eigenart der begangenen Tat bzw. des $T{\ddot{a}}ters$ zu individualisieren. Das Gebot der Individualisierung der Strafen, welches $haupts{\ddot{a}}chlich$ vom materiellen Rechtsstaatsprinzip ableitbar ist, kann im Grunde nur verwirklicht werden, wenn das Gericht dazu befugt ist, unter $Ber{\ddot{u}}cksichtigung$ der konkreten $Umst{\ddot{a}}nde$ jedes Einzelfalls ${\ddot{u}}ber$ eine angemessene Strafe zu befinden. Somit ist der kraft Gesetzes eintretenden Verlust der $Amtsf{\ddot{a}}higkeit$ und der $W{\ddot{a}}hlbarkeit$ nur schwer mit dem Gebot der Individualisierung der Strafen vereinbar. Es $w{\ddot{a}}re$ deshalb $w{\ddot{u}}nschenswert$, wenn der Gesetzgeber eine Reform in Betracht ziehen $w{\ddot{u}}rde$, welche den Ersatz des kraft Gesetzes automatisch eintretenden Entzugs der $Amtsf{\ddot{a}}higkeit$ bzw. des Wahlrechts durch die gerichtliche fakultative Aberkennung von diesen Statusrechten beinhaltet.

  • Cyber Kill Chain is derived from Kill chain of traditional military terms. Kill chain means "a continuous and cyclical process from detection to destruction of military targets requiring destruction, or dividing it into several distinct actions." The kill chain has evolved the existing operational procedures to effectively deal with time-limited emergency targets that require immediate response due to changes in location and increased risk, such as nuclear weapons and missiles. It began with the military concept of incapacitating the attacker's intended purpose by preventing it from functioning at any one stage of the process of reaching it. Thus the basic concept of the cyber kill chain is that the attack performed by a cyber attacker consists of each stage, and the cyber attacker can achieve the attack goal only when each stage is successfully performed, and from a defense point of view, each stage is detailed. It is believed that if a response procedure is prepared and responded, the chain of attacks is broken, and the attack of the attacker can be neutralized or delayed. Also, from the point of view of an attack, if a specific response procedure is prepared at each stage, the chain of attacks can be successful and the target of the attack can be neutralized. The cyber command and control system is a system that is applied to both defense and attack, and should present defensive countermeasures and offensive countermeasures to neutralize the enemy's kill chain during defense, and each step-by-step procedure to neutralize the enemy when attacking. Therefore, thist paper proposed a cyber kill chain model from the perspective of defense and attack of the cyber command and control system, and also researched and presented the threat classification/analysis/prediction framework of the cyber command and control system from the defense aspect
