The purpose of this study was to investigate the effects of smoking on adult periodontitis after non-surgical periodontal therapy. The study population consisted of 40 patients with moderate to advanced periodontitis. Smokers(n=20) were defined as individuals smoking at least twenty cigarettes per day at the time of the initial examination. The non-smoking group(n=20) consisted of individuals who were not smoking at the initial examination. The average age was 42.4 years for the smoking and non-smoking group. Examination regarding plaque index, gingival index, pocket depth and contrast phase microscope were performed. Evaluation were made at the first, the second and the fourth weeks after periodontal non-surgical therapy. The results were as follows: 1. Clinical indices including plaque index, gingival index, and pocket depth were decreased in both smoking and non-smoking group at the first, the second, and the fourth weeks. Especially, clinical indices of non-smokers were more significantly decreased than those of smokers. 2. Non-motile rods were increased and motile rods were reduced at the fourth week. spirochetes were reduced significantly in the non-smoking group at the fourth week. These results suggest that smoking play a minor role in adult periodontitis after non-surgical periodontal therapy.

Purpose: The purpose of this study was to explore the resilience of adult children of alcoholics (ACOA) who are college students, and examine factors contributing to their resilience. Methods: A total of 459 college students from a university in Incheon, participated in this study. Data were collected between April 6 to 30, 2010 using the Korean version of the Children of Alcoholics Screening Test (CAST-K), CAGE, Social Support, Self-Esteem, Family Adaptability and Cohesion, and Resilience measurements. Data were analyzed using the SPSS/WIN 18.0 program. Results: Overall, ACOA group showed lower scores of resilience, social support, self-esteem and family adaptability and cohesion compared to non-ACOA group. Resilience among the ACOA group showed significant relationships with self-esteem (r=.53, p<.001), social support (r=.43, p<.001), and family adaptability and cohesion (r=.25, p<.013). Multiple regression analysis showed that 45% of the variance for resilience in the ACOA group was accounted for by age, gender, social support, self-esteem, and religion. Conclusion: The results of the study show that self-esteem and social support are important determinants of resilience in ACOA, thus it is recommend that further resilience training programs for ACOA be developed to enhance their social support and self-esteem, and ultimately to increase their resilience.

The purpose of this study was to analyse craniofacial shape by 3D scanner for Korean adult head shape by age group. The heads of 836 adults were measured by 3D scanner, and the 25 obtained measurements were analyzed by statifical methods. The results can be summarized as follows. 1. From the basic statistical data analysis, the vertex-tagion and the length between the pupils were the longest in the subjects in their twenties, and decreased in elderly groups. 2. According to the analysis of the craniofacial proportion, the typical adult Korea head type was short-headed. 3. Statistically noticeable differences were found in the ectocanthion- opistcranion by the measurement of the left and the right sides of face in the age groups of the 20s, 30s, 40s, and 50s. 4. The order of factor analysis was as follows: the horizontal length, the perpendicular length and the width from the highest in the age group of the 20s, 30s, 40s, and 50s.

Purpose: The goal of this study was to investigate the causative factors related to the stress of temporomandibular disorders (TMDs) by evaluating salivary cortisol concentration in young adult TMD patients and control groups. Methods: Saliva was obtained from 32 young adult TMDs patients and 34 control patients without a history of TMDs who visited Chosun University Dental Hospital between June 1 and August 31, 2021. Enzyme-linked immunosorbent assay was conducted to measure the salivary cortisol concentration. Results: The salivary cortisol concentration in the TMD patient group and the control group differed significant significantly (p<0.05). The salivary cortisol concentration according to the duration of the clinical symptom of TMD differed significantly difference between the two groups in the male. The salivary cortisol concentration according to perceived stress level differed significantly in the mild and moderate groups (p<0.05). There was no significant difference in salivary cortisol concentration between the two groups related to bruxism or clenching (p>0.05). Conclusions: The salivary cortisol concentration in the TMD patient group and the control group showed statistical relevance, indicating that stress was a causative factor.

This study was conducted to find out how young black-tailed gulls (Larus crassirostris) recognize adult voice signals after hatching. For the experiment, adult voice recorded in the natural environment was played back at controlled intervals and intensity (dB) to 15 young gulls that were artificially hatched in the laboratory. The chirirah call frequency of young gulls increased as the intensity of the mew call increased. The chirirah response of the control group was highest to the mew call at intervals of 1.8s. The adult long ca11 and alarm call also showed similar results to the mew call when the interval and intensity were manipulated similar to the mew call. Based on the results of this experiment, it is assumed that the young black-tailed gulls recognize adult voice signals based on the simple structure of adult voice signals, that is, the interval and intensity of the voice.

Background and objectives: Chromosomal abnormalities play an important role in genesis of acute lymphoblastic leukemia (ALL) and have prognostic implications. Five major risk stratifying fusion genes in ALL are BCR-ABL, MLL-AF4, ETV6-RUNX11, E2A-PBX1 and SIL-TAL1. This work aimed to detect common chromosomal translocations and associated fusion oncogenes in adult ALL patients and study their relationship with clinical features and treatment outcome. Methods: We studied fusion oncogenes in 104 adult ALL patients using RT-PCR and interphase-FISH at diagnosis and their association with clinical characteristics and treatment outcome. Results: Five most common fusion genes i.e. BCR-ABL (t 9; 22), TCF3-PBX1 (t 1; 19), ETV6-RUNX1 (t 12; 21), MLL-AF4 (t 4; 11) and SIL-TAL1 (Del 1p32) were found in 82/104 (79%) patients. TCF3-PBX1 fusion gene was associated with lymphadenopathy, SIL-TAL1 positive patients had frequent organomegaly and usually presented with a platelets count of less than $50{\times}10^9/l$. Survival of patients with fusion gene ETV6-RUNX1 was better when compared to patients harboring other genes. MLL-AF4 and BCR-ABL positivity characterized a subset of adult ALL patients with aggressive clinical behaviour and a poor outcome. Conclusions: This is the first study from Pakistan which investigated the frequency of5 fusion oncogenes in adult ALL patients, and their association with clinical features, treatment response and outcome. Frequencies of some of the oncogenes were different from those reported elsewhere and they appear to be associated with distinct clinical characteristics and treatment outcome. This information will help in the prognostic stratification and risk adapted management of adult ALL patients.

To compare response of feeding concentrate mixtere and wheat straw (Group I) with either urea molasses liquid diet (UMLD) as sole ration (group II) or UMLD (similar to protein equivalent of concentrate mixture) plus wheat straw (group III) on intake and utilisation of nutrients and overall performance, twelve crossbred adult male cattle (Holstein Friesian ${\times}$ Hariana) aged about 2.5 years and weighing 342 kg were randomly allotted into three equal groups following completely randomised design and fed respective diets for a period of 60 days. Thereafter, a metabolism trial of seven days duration was conducted to assess nutrient utilisation and nitrogen balance. Animals fed UMLD as sole ration consumed significantly (p < 0.01) less amount of most of the nutrients as compared to other two groups, except crude protein, intake of which was higher in this group but it was comparable between II and III and III and I. On the other hand, digestibilities of nutrients were higher (p < 0.01) in group II, though it was comparable between other two groups, except ADF, the digestibility of which was lower in group II. Inspite of positive nitrogen balance in all the three groups, being significantly (p < 0.01) higher in group I, animals of group II and III lost their body weight especially to the utmost extent in group II, although the amount of energy (TDN) intake were similar statistically. Results indicate that during a scarcity period and economic compulsions, feeding of UMLD can be practised to replace only concentrate mixture from the maintenance ration of adult crossbred cattle for shorter duration as roughage part seems to be essential for the normal functioning of the rumen microbes and overall performance of the animals.

Background and Objectives: Vocal polyps arc one of the most frequent benign laryngeal diseases. They arc usually found at the midpoint of the vocal fold. They are mainly caused by vocal overuse. Vocal polyps arc usually removed surgically. Generally, age-related changes to speech are attributed to change in anatomy and physiology of the speech mechanism. These changes result in increased variability in the acoustic properties of speech with age. Still, not 'all studies of age-related changes in speech have taken differences between the young group and adult group after laryngeal microsurgery into account. The aim of this investigation was to compare improvement of acoustic analysis in young patients and elderly patients with vocal polyps, before and after the laryngeal microsurgery. Materials and Method: One hundred and twenty-eight patients who underwent laryngeal microsurgery for vocal polyps from 2008 through 2011 were reviewed retrospectively. 105 of the 128 patients under age 60 were classified as adult group (AG), and remaining 23 patients as elderly group (EG). The speech of AG and EG were evaluated before and after surgery for identification of differences for age group across measures of fundamental frequency (F0), Jitter, Shimmer and Maximum phonation time (MPT). Results: There were not significant differences between two groups for improvement of F0, Jitter, Shimmer, NHR, and MPT before and after surgery. The findings suggest that elderly group compares quite well with adult group in effectiveness of surgery. However, comparison between elderly group and young group (Age under 40) there was significant difference of improvement in Jitter and Shimmer. Conclusion: In general, the results of the present research showed significant improvement in vocal quality after phonosurgery of vocal polyp in both elderly and adult group. However, comparison of improvement between elderly group and young group, there were significant differences of improvement in jitter and shimmer. Therefore, in treatment planning of elderly group, we should consider age related changes of vocal cord.

1. Objectives The purpose of this study lies on the objectification of the Sasang Constitutional diagnosis. This study was analyzing the constitutional characteristic of adult men voices by PSSC-2004. 2. Methods The study was conducted on the subjects inputted /a/ 2.5-3 sec of 231 adult men voices to PSSC-2004. The statistical analyses are applied to three groups: total group, under 55 year-old group, over 55 year-old group. The group of total 231 was composed with 5 Taeyangins, 32 Soyangins, 102 Taeumins and 92 Soeumins. The under 55 years old group was composed with 4 Taeyangins, 23 Soyangins, 83 Taeumins and 77 Soeumins. The over 55 year-old group was composed with 1 Taeyangin, 9 Soyangins, 19 Taeumins and 15 Soeumins. 3. Results 1) In total group, the Soeumin's mean value of center pitch(4)$(1,000{\sim}2,000Hz)$ was significantly high compared with the others (P=0.034). 2) In total group, the Soeumin's group 3 APQ was significantly low compared with the others (P=0.042). 3) In under 55 year-old group, the Soeumin's center value of center pitch 4$(1,000{\sim}2,000Hz)$ was significantly high compared with the others (P=0.025) 4) In over 55 year-old group, no statistical significance was found between the Taeyangin, Soyangin, Taeumin and Soeumin. 4. Conclusions In under 55 year-old group, Soeumin's voice showed high pitched sound (clearness) at the low frequency (1000-2000Hz). In over 55 year-old group, there is no significant differences. This fits in with that 'Soeumin's voice is 'Yu-tone' born by 'Shang-tone', very short and high.' 'Yu-tone' corresponds to 'Ra' and witch is highest among Gong, Shang, Gao, Chi and Yu. This is related with the appearance that the Soeumin's voice is weak, thin and high tone. Therefore it is supposed that Soeumin adult men's voices are thick, and there are vibrations of the ending. It is accepted one of the Soeumin's characters like as a mild tremor of limbs and deep breath caused by Soeumin's Qi-deficiency. This outcome accords with the theory that Soeumin's Qi is less than the Other constitutions.

We studied blood salvage effect of Cell Saver Apparatus[CSA with adult cardiac patients. This study compares blood salvage in two groups of patients undergoing valve replacement or congenital cardiac operation.Group 1 is composed with 60 patients operated during 1991-1992 using CSA. Group 2 is composed with 60 patients operated during 1990-1991. No special effort was made to salvage blood in Group 2. The average requirements in Group 1 were approximately one-fourth the amount of RBC products by Group 2. The hospital course, blood chemistry level were comparable for the two groups. CSA produced blood was concentrated, well oxygenated blood and the average amount was 830 ml. Any complication was not detected in transfusion of CSA produced blood. This study shows that CSA allows safe and practical blood salvage during adult cardiac operations.
