Background and Objectives : This study aimed to determine the clinical effect of $Artecoll^{(R)}$ injection laryngoplasty for patients with vocal atrophy and mild sulcus vocalis. Materials and Method : Forty-one patients with vocal atrophy and/or mild sulcus vocalis received transcutaneous $Artecoll^{(R)}$ injection into the vocal folds under local anesthesia. Subjective evaluations including voice handicap index (VHI) and perceptual grading with Grade, Roughness, Breathiness, Asthenia, Strain (GRBAS) scales and objective evaluations including jitter, shimmer, noise-to-harmonic ratio (NHR), speaking fundamental frequency (SFF) and maximum phonation time (MPT) were evaluated before and 3 months after the injection. Results : VHI and Grade, Breathiness and Strain scales in GRBAS showed significant improvement 3 months after injection. SFF and MPT also significantly improved after the injection ; MPT increased and SFF in male patients decreased. Conclusion : Injection laryngoplasty with $Artecoll^{(R)}$ is an effective method for correcting the glottal insufficiency and improving voice quality in patients with vocal atrophy and/or mild sulcus.

Acoustic analysis study was performed on 20 normal subjects by speaking nonsense syllables composed of Korean bilabial stops(/p, $p^{*}$/, ph/) and their Preceding and/or following vowel /a/(that is, [pa, $p^{*}a$, pha, apa, $ap^{*}a$, apha]) with an ultraminiature pressure sensor in their mouths. Speech materials were phonated twice, once with a moderate voice, another time with a loud voice. The acoustic signal and intraoral pressure were recorded simultaneously on computer. By these procedures, we were to measure the intraoral pressure, closure duration and VOT of Korean bilabial stops, and to compare the values one another according to the intensity of phonation and the position of the target consonants. Intraoral pressure was measured by the peak intraoral pressure value of its wave; closure duration by the time interval between the onset of intraoral pressure build-up and the burst meaning the release of closure; Voice onset time(VOT) by the time interval between the burst and the onset of glottal vibration. Heavily aspirated bilabial stop consonant /ph/ showed the highest intraoral pressure value, unaspirated /p$^{*}$/, the second, slightly aspirated /p/, the lowest. The syllable initial bilabial stops showed higher intraoral pressure than word initial stops, and the value of loudly phonated consonants were higher than moderate consonants. The longest closure duration period was that of /$p^{*}$/ and the shortest, /p/, and the duration was longer in word initial position and in the moderate voice. In VOT, the order of the longest to shortest was /ph/, /p/, /$p^{*}$/, and the value was shorter when the consonant was in intervocalic position and when it was phonated with a loud voice.

By evaluating the health status by Cornell Medical Index in conjunction with their academic grade, we attempted to find out whether any health condition may affect on their academic carrier. CMI health questionnaire was filled out by student and matched with one's own academic score if the previous year. Academic score was classified into 5 grades: excellent, very good, good, fair and poor. Difference in number of questions between sections was corrected by standard score method with means of 50 and standard deviation of 10. Differences in number of 'yes' answers between sections and between groups of students in each grade were statistically tested by two-way variance analysis method. On the other hand, influence of neuropsychiatric factors (section M-R) on the academic carrier was analyzed by $X^2-test$ with Fukamachi's classification. The following were the results obtained in this study: 1) Number of 'yes' answers in sections related to mood and feeling patterns (sections M-R) were appeared to be influential to academic carrier in male students, but not in female students. 2) Generally speaking, in groups of higher academic grade, number of 'yes' answers in each section was on an averege 50 or less, and in groups of lower academic grade, the number was 50 or more depending on sections. 3) Number of 'yes' answers between sections and between groups in each academic grade were significantly different both in male and female college students. 4) It was noteworthy that data obtained from CMI questionnaire might be variable subjectively by examinees with some factors at the time of administration.

This work is a part of our project to establish a Website which provides a list of magnetic clouds (MCs) identified by WIND and ACE spacecraft. MCs are characterized by their magnetic fields that are well described by magnetic flux rope structures, whereas interplanetary coronal mass ejections (ICMEs) are interplanetary manifestations of coronal mass ejections (CMEs), usually identified by differences of plasma and magnetic field characteristics from those in the background solar wind. It is widely accepted that, while MCs are generally identified within ICMEs, the number of MCs are significantly lower than the number of ICMEs. In our effort to identify MCs, however, we have found that there was a big problem in identification method of MCs in previous works. Generally speaking, most of the previous surveys failed in identifying MCs which encounter the spacecraft at large distances from the MC axis, or near the surface of MC structures. In our survey, MCs are identified as the region of which magnetic fields are well described by appropriate flux rope models. Thus, we could selected over 45 MCs, in 1999 solar wind data for instance, while 33 ICMEs are listed in the Website of the ACE Science Center reported by Richardson and Cane.

Erdheim chester disease (ECD)은 골격계 및 다발성 장기에 발생하는 매우 드문 비 랑거한스세포 조직구증(Langerhans cell histiocytosis,LCH)으로 구분되는 질환으로 진행성이며 때론 치명적인 결과를 야기한다. 하지만 이는 LCH 혹은 다발성 골 전이로 오인되기 쉬우며 진단 또한 극히 어렵다. 국내에서는 1999년에 10예가 처음으로 보고되었을 뿐이며 특히 정형외과적으로 접근 및 보고는 문헌상 영어권에서 극히 소수의 문헌만이 존재하며 국내에는 보고된 예가 없다. 저자들은 슬관절 및 하지통은 주소로 본과에 협진된 환자에 대해 골 조직검사 시행하였으며 이에 대한 진단적 경험을 문헌 고찰과 함께 보고하고자 한다.

This study aims to understand the Process of Communality formation among the Families of Communal Childcare Cooperative. Ethnographic, in-depth interview and participant observation at field are used as method. The families of communal childcare cooperative form their communality through investment and harmony, making relationship, and struggles and overcoming the struggles. Each family is willing to put in their money and time for an unfamiliar group to organize and manage a community. They head for the same direction accepting the diversity of expectation and thought based on the diversity of environment of each family. They have interactions upon the basis of equality among the families. Sharing their unique cloture such as communal place(teojeon), common issues, same generation, unique terms, specific modes of speaking informally or nicknaming, they accept the diversities and head for the sameness to have a harmony. In the reset of forming relationship, these families transfer successfully from the field of I and my family to that of group. They escape from a sense of priority that concerns their own family first and then others. They come to be able to consider the group first. Besides, they come to assimilate themselves to the group by identification with the group. They come to form their identity and sense of membership of the group recognizing power of group they belong in their families and local society. The process of forming community among the families of cooperative has inescapable struggles. Each family becomes a real host of the cooperative in the process of overcoming the struggles and experiences a growth of individual and group in the process of looking for the ways of overcoming the struggles. In the end, the families cooperates and reestablish their community.

Nausea, vomiting and retching are universal symptoms that affect individuals' state of health and self-care activities of individuals. Accurate measurements of individual symptoms are required to gather more definitive data, and enhance understanding, planning, and implementation of self-care actions. Recently the Rhodes Index of Nausea, Vomiting, and Retching(INVR), a new format of the INV-2(the Rhodes Index of Nausea and Vomiting), was developed to measure the symptoms of nausea, vomiting and retching in an English speaking population. To determine the reliability and validity of the INVR, and the possibility of using the instrument in Korea, the Korean translation of the INVR and the INV-2 were administered to a convenient sample of 105 patients at two University Hospitals in Kwangju, Korea. The Cronbach's alpha to estimate the internal consistency of reliability for INVR was 0.844. Equivalent measures of reliability were conducted to determine the percentage of agreement and the Spearman rank correlation coefficients for responses on the two instruments. The percent agreement was 83% and the correlation coefficient was 0.906 over all. A significant differences between the INVR scores of the patients with and without nausea, vomiting, or retching were seen, which indicated a construct validity. The INVR was found to be more user friendly for the patient and the healthcare providers. As a result, it is suggested that the INVR can provide a scientific base for measuring the symptoms of nausea, vomiting, and retching for nurses to improve patients' care and quality of life.

Purpose: The purpose of this study was to identify the predictors of acculturative stress among Chinese students in Korea. Methods: Between October and December 2009, two hundred one Chinese students from three universities located in Cungnam province, were included in the current study using a questionnaire survey. Data analysis was done using SPSS/WIN 17.0 program. Results: The average score of acculturative stress was $38.50{\pm}6.97$. There were significant differences in acculturative stress according to educational level, economic status, type of residence, speaking skill in Korean, listening skill in Korean, grade point average, satisfaction for studying abroad, and perceived health status. The acculturative stress was significantly correlated with depression, resilience and social support. The strongest predictor of acculturative stress among Chinese students was depression. Conclusions: The findings suggest that developing programs to improve psychological health may provide a buffer against acculturative stress experienced by migrating Chinese students. Furthermore, more studies are needed to explore variables that influence on the international students' acculturation in Korea.
