Objective : Low back pain (LBP) is a global health problem that affects the productivity of the patients. Several factors such as individual, occupational, and psychosocial factors increase the risk of LBP. However, only a few studies investigated those factors, especially in middle adulthood in Indonesia. Indonesia is a country with a young population that has been rapidly developing in recent years. This study was conducted to find out the factors associated with LBP in middle adulthood. Methods : This study is a cross-sectional observational analytic study using a convenience sampling method with a total sample of 3005 respondents. Data were collected using a questionnaire which was then analyzed using the chi-square test, Kolmogorov-smirnov, Spearman's Rank, and logistic regression test. Results : From the result of this study, it was found that the 12-month prevalence of LBP in middle-aged adults was 44,29%. Female (odds ratio [OR], 1.3; 95% confidence interval [Cl], 1.098-1.545; p=0.002), lack of physical exercises (OR, 0.87; 95% Cl, 0.794-0.959; p=0.005), high body mass index (OR, 1.09; 95% Cl, 1.009-1.187; p=0.002), stress level (OR, 1.26; 95% Cl, 1.088-1.458; p=0.002), and years of work experience (OR, 1.1; 95% Cl, 1.001-1.225; p=0.047) were determined as risk factors that significantly associated with LBP. Conclusion : LBP is quite common among middle-aged adults in Indonesia. Female gender, higher body mass index, lack of physical activity, stress level, and years of work experience were all potential risk factors for LBP in middle-aged adults. Middle-aged adults in Indonesia should be aware of LBP and avoid disabilities by identifying risk factors that may worsen LBP in the future.

Objective: The purpose of this study was to investigate the influence of experiences in close relationships with teachers for young children on their depression and to see whether there would be a mediating effect of their self-compassion. Methods: The subjects were 206 teachers recruited from Seoul and five different provinces who currently worked at the kindergarten and child care centers and agreed to participate in the survey. The data were analyzed by means of frequency, percentages, Cronbach's reliability coefficient and Pearson's correlation using SPSS 25.0 and model 4 provided in The PROCESS macro for SPSS 3.4 version. Results: The findings were as followed. First, the teachers' degrees of anxiety and avoidance for their close relationships were below the median scores. In contrast their degree of self-compassion was above the median score. In addition, their level of depression was relatively low. Second, both of the teachers' anxiety and avoidance for their close relationships had a positive impact on their depression and their self-compassion, and there were the partial mediating effect in both cases. Conclusion/Implications: These results imply that the early attachment experience connecting the experience in close relationships in the adulthood is important and that it is necessary to develop a program to enhance teachers' self-compassion to protect their psychological well-being.

The copy numbers of the CTG repeats are known to relate to the severity of clinical symptoms for myotonic dystrophy. The positive correlation between clinical manifestations and CTG repeat size has been demonstrated previously. A genetically confirmed myotonic dystrophy patient with 90 CTG repeat number had more severe clinical manifestation than brother with 120 CTG repeats, in adulthood.

The mutational falsetto is failure to change from the higher pitched voice of preadolescence to the lower pitched voice of adolescence and adulthood. The one of characteristic findings is contraction of suprahyoid muscles. The large majority of young men with inappropriately high voice have excellent voice therapy prognosis. We have experienced one case of mutational falsetto treated with botulinum toxin injection on suprahyoid muscles. His suprahyoid muscles are contracted markedly simultaneously with each phonation. fundamental frequency$(F_0)$ of his vowel phonation was 332Hz. Extensive voice therapy including manual compression of thyroid notch was ineffective. Forty units of Botox$^{\circledR}$ was injected under the EMG-guidance(20U bilaterally). At seven days post-injection, his voice changed lower than before and at 40 days after procedure, his $F_0$ was 126Hz.

The incidence of small for gestational age (SGA) births is frequent, accounting for 2.3% to 8% of all live births. Several childhood and adult diseases are related to early postnatal growth and birth size, and 10% of children born SGA may have a short stature throughout postnatal life. Additionally, they may have abnormal growth hormone (GH)-insulin like growth factor axis, HPA axis, and gonadal function. Permanent changes are detrimental in an environment of nutritional abundance, and predispose SGA children to an array of diseases in adolescence and adulthood. Such changes may also cause premature pubarche, adrenarche, and precocious puberty. The varying results from clinical studies necessitate more prospective case control studies. Reproductive tract abnormalities and reproductive dysfunction are related to SGA births. GH treatment is required for SGA infants who do not experience catch-up growth.

The normal aging process on speech production and these changes are perceived by listeners. This study examined whether age perception changed under various conditions of prosodic manipulations in normal listeners, comparing the prosodic changes according to age and sex in adulthood. The older and younger voices were resynthesized by manipulation of the speaking rate and pitch to shift the perceived age of the groups toward each other. Two-way repeated ANOVA were conducted to determine if the prosodic type of resynthesized cue resulted in a significant shift in perceived age of young and old voices. The manipulation of the speaking rate resulted in a significant shift in perceived age for the older and younger groups. A significant shift in age estimates was not observed for the younger male group when pitch was manipulated. There were significant gender-by-age group interactions for prosodic manipulation type. Age-related changes in the prosodic properties of speech may ultimately influence speech perception.

Ecological aspects of Cryptocercus kyebangensis life history were investigated via laboratory rearing and field observations. The number of antennal segments and head width were used to classify the first four instars. The results, which combine both the field collection and the laboratory rearing, indicate that eleven instars occur in C. kyebangensis. It supports the proposal on the number of instars of Park and Choe (2003c) based on field collections. A total of 388 nymps from 13 colonies were collected prior to winter to investigate overwintering stages. Of them,4％ (n = 17) were the second instars, 57％ (n = 220) were the third instars, and 39％ (n = 151) were the fourth instars, respectively. Thus, most of them overwinter in the third or fourth instars. The results indicate that young nymphs of C. kyebangensis have to reach at least 3rd or 4th instar to survive low temperature environment of winter. According to seasonal dynamics of populations, C. kyebangensis reaches adulthood in the summer of the fourth or fifth year (4-5 yr span) after their birth.

Twenty-one adoptive parents participated in this study on adoption-related conflicts perceived by adoptive parents in open adoption. Q-methodology, which provides understanding of individual attitudes and experiences, identified three types of conflict. Type 1 experienced a great deal of conflict and concern prior to the adoption decision; they also faced difficulties stemming from lack of information about parenting an adopted child and institutional inertia. For type 2, the major factors of conflict were discord among siblings, negative bias against adoption in the community, and insufficient national assistance. Type 3 reported that they feel concerned for their adopted-child's developmental and psychological wellbeing they worried that adoption status might lead to behavioral and attitudinal problems in their adopted-child during youth and young adulthood.

Ichneumonidae are well-known parasitoids that attack the larvae or pupae of other insects. This study analyzed whether the abdominal DNA of two ichneumonid wasps, Pimpla disparis and Theronia atalantae gestator, showed the signature of the host species, Ivela auripes. Observations confirmed that these two ichneumonids were the representative parasitoid species growing in the larvae of I. auripes. In addition, sequence analysis showed that the mitochondrial cytochrome oxidase I gene of the host was amplified completely from the DNA extracted from the gut tissues of the ichneumonids. Even after 96 h of adulthood, the host's DNA traces did not disappear and were amplified in many individuals. These results suggest a constructive first step for establishing of a host information bank for ichneumonids in the future.
