The distributed species and the kinds of variable microorganism in Pharynx were monitored to the elementary school child. Our purpose was to investigate the distribution of bacteria in Pharynx of child except for adults. Analysis performed the collected sample from 15 students in Chungnam area for 2 days from July 30 to July 31 in 2012. The isolated bacteria were identified by Gram stain and biochemical test using VITEKⅡsystems. The experiment on microorganism concentration of contact parts carried out and the average of total microorganism was measured. The elementary child's Pharynx were isolated and identified. The isolation rates were major distributied to Gram positive cocci, another Gram negative bacilli and Gram positive bacilli. respectively. The frequently isolated bacteria were G. adiacens. The Granulicatella adiacens is one of the fastidious Gram positive cocci previously described as nutritionally variant streptococci due to their requirement of L-cysteine, pyridoxal, or thiol compounds for growth. These bacteria have been identified as significant causative agents of endocarditis, opthalmic infections, and meningitis. Further systematic studies are necessary with an emphasis on species identification. Key Words : Microorganism, Elementary child, Pharynx and Larynx

Objectives: The purpose of this study was to clarify and elaborate the concept of implicit self-esteem by identifying parenting domains that are related to implicit self-esteem as well as by comparing the correlation between parenting behaviors and children’s explicit and implicit self-esteem (ESE & ISE). Furthermore, based on previous studies’ emphasis on the functions of self-esteem discrepancies, 4 groups of self-esteem types were included in the analysis: secure self-esteem, defensive self-esteem, damaged self-esteem and congruent low self-esteem. Methods: Participants were 279 Korean middle school students (114 boys and 165 girls). Children’s ESE and ISE were measured using the Rosenberg Self-Esteem Scale (RSES) and the Name-Letter Task (NLT), respectively, and the parenting behavior measure consisted of 8 domains: monitoring, reasoning, inconsistency, over-involvement, over-expectation, neglect, physical abuse, and affection. Considering the effect of gender on the parent-child relationship, analysis was conducted according to gender. Results: Comparison between the correlations revealed that among 32 factors, differences in ESE and ISE were significant in 13 factors and not significant in 19 factors. Further, most of the parenting domains were significantly related to both daughters’ and sons’ ESE, while only a few of father and mother’s parenting domains were related to ISE. Boys’ ISE was negatively related to fathers’ over-involvement and mothers’ reasoning, while girls’ ISE was positively related to both parents’ monitoring and negatively related to neglect. Additionally, the group with secure self-esteem (characterized by high ESE and high ISE) mostly reported high levels of positive parenting behaviors and low levels of negative parenting behaviors, while the group with congruent low self-esteem (characterized by low ESE and low ISE) mostly reported low levels of positive parenting behaviors and high levels of negative parenting behaviors. Conclusion: This study contributes significant findings to the understanding of ISE. Based on the current study’s results, it is plausible to conclude that ISE performs a similar function to ESE, yet weaker. Moreover, the importance of measuring mothers’ and fathers’ parenting behaviors separately could be more emphasized. Further discussions are suggested regarding areas of contention over the formation and the concept of ISE.

In this study, Korean Hallabong produced in Jeju Island and coffee were grafted to prepare coffee containing Hallabong extract and the nutritional components were analyzed. As the amount of Hallabong extract increased, the water content and total polyphenol content increased. However, the crude flour, crude protein, and total flavonoid content decreased significantly. The selenium content per 100 g was 91.28 mg in the 1% Hallabong group, and the iron content was 6.84 mg in the 3% Hallabong group. As the content of Hallabong extract in coffee increased, the L-value (brightness) and b-value (yellowness) increased, but the a-value (redness) showed a tendency to decrease. In the case of DPPH(2,2-Diphenyl-1-picrylhydrazyl) radical scavenging activity, the group containing 9% of Hallabong extract showed the highest value at 47.20 μmol/g of TEAC. In particular, the ABTS(2,2’-Azino-bis(3-ethylbenzothiazoline- 6-sulfonate)) and DPPH radical scavenging activity were significantly increased from coffee powder containing 6% or more of Hallabong extract(p<0.05). The caffeine content decreased as the amount of Hallabong extract added to coffee increased. Therefore, when making powder coffee with Hallabong extract added, it is recommended to set the content of Hallabong extract to 6%.

This paper presents analysis and comparison of preprocessing performance for the two techniques, SQI(Self-Quotient Image) and a bilateral filter, which is recently proposed for preprocessing of magnetic flux leakage signals. There are many defects and deformation on underground pipelines because of corrosion and deformation by external forces. The most widely used technique is the method using magnetic flux leakage in order to detect and manage the defects and those history. Magnetic flux leakage signal is gathered by using a PIG(Pipeline Inspection Gauge) which is inserted in pipelines and magnetized the pipeline walls. The variation of the leakage signal is used to determine the level of deterioration of pipelines, but the leakage signal gets also damage because of many known and unknown causes. To efficiently process the noise and detect of defects easily in the following stages various type preprocessing and noise handling techniques is applied. Two preprocessing techniques using SQI and a bilateral filter is proposed recently. This paper tries to analyze the advantage and disadvantage of the two methods by applying the preprocessing of magnetic flux leakage signals. The difference of the two methods are visualized and we performed quantitative analysis. 본 논문에서는 자기누설신호의 전처리 기법 중 가장 최근에 발표된 SQI와 양방향필터의 성능을 비교 분석하였다. 지하에 매설된 배관의 경우 외부의 부식 환경이나 외력에 의해 다양한 종류의 손상이 발생할 수 있다. 이러한 손상을 파악하고 손상 이력을 관리하기 위해 전계계적으로 가장 많이 사용되는 기법이 자기누설신호를 이용하는 방법이다. 자기누설신호를 획득하기 위해서는 배관 내부에 PIG 라 불리는 장치를 삽입하고 영구자석으로 배관을 자화시킨 후 누설자속을 측정한다. 측정된 누설자속의 변화로부터 배관의 손상정도를 파악하는데, 일반적으로 누설자속신호에는 다양한 잡음들에 혼재한다. 이러한 잡음을 효과적으로 처리하고 다음 단계의 결함 검출을 용이하게 하기 위해 다양한 형태의 전처리나 노이즈 처리 기법들이 적용된다. 최근에 전처리 기법으로 SQI를 이용하는 방법과 양방향필터를 이용하는 방법들이 제안되었다. 본 논문에서는 이 두 기법을 실제 누설자속신호에 적용하여 장단점을 분석하고자 하였다. 실험 결과를 통해 그 기법의 차이를 가시화하였으며, 정량적인 분석도 시행하였다.

본 연구에서는 살균 및 비가열압착한 들깨오일(superilla)을 활용하여 영양성분을 확인하고 기능성 식품으로서의 가능성을 알아보기 위해 시판되는 들기름과 비교실험을 수행하였다. 수분 함량과 pH는 CPPO에서 높았고, 구리, 코발트, 칼슘 함량은 SRPO에서 높았다. 총 비타민 E, 토코페롤, 리놀렌산 함량은 LPPO에서 더 높았다. 총 폴리페놀 함량과 ABTS 라디칼 소거활성은 SRPO에서 가장 높은 수치를 보였으며, 아질산염 소거능 측정값은 CPPO에서 가장 높았다. L 및 a 값은 CPPO에서 더 높았고 b값은 LPPO에서 더 높았다. 이상의 결과를 통해 살균 및 비가열압착한 들깨오일(SRPO)의 무기질 함량, 총 폴리페놀 함량, ABTS라디칼 소거활성 및 아질산 소거능이 있음을 확인하였다. 또한 시간이 경과할수록 SRPO는 과산화물가가 낮았고, LPPO는 산가가 유의하게 증가하였다. 따라서 본 연구를 종합해 볼 때, 살균 및 비가열압착한 들기름의 경우 기존의 방식으로 생산된 들기름과 영양소 성분이 유사하였다. 이는 새로운 들기름 제조방법을 제공하는 계기가 되었으며, 이를 통해 들기름의 상품화의 기초가 마련되었다고 판단된다. In this study, the nutritional properties of sterilized and non-heat-pressed raw perilla oil (SRPO) were studied and its potential as a functional food was evaluated. The copper, cobalt, and calcium levels were high in sterilized and SRPO. The total polyphenol content and ABTS radical scavenging activity were the highest in SRPO, whereas nitrite scavenging activity was the highest in 45℃ cold pressed perilla oil (CPPO). The above results confirmed that sterilized and non-heat-pressed perilla oil had high mineral and total polyphenol contents, as well as ABTS radical scavenging activity and nitrite scavenging ability. The peroxide value of SRPO decreased as the storage period increased, and the acid value of low-temperature pressed perilla oil over 65℃ (LPPO) significantly increased. This work also provided an opportunity to develop a new method for manufacturing perilla oil, and it is hoped that these experiments will form a basis for the commercialization of perilla oil.
