하늘소류 기생천적으로 알려진 개미침벌의 발육, 산란과 우화, 성비를 조사하기 위해 기주곤충인 솔수염하늘소, 북방수염하늘소, 울도하늘소의 노숙유충과 번데기를 먹이로 제공하였다. 개미침벌 암컷의 발육은 솔수염하늘소 유충과 번데기에서 $29.2{\pm}0.93$일, $25.1{\pm}0.47$일, 북방수염하늘소 유충과 번데기에서는 $27.1{\pm}0.41$일, $26.0{\pm}0.69$일, 울도하늘소 유충과 번데기에서는 $26.3{\pm}0.38$일, $31.2{\pm}0.24$일이 각각 소요되었다. 개미침벌 성충은 솔수염하늘소 번데기를 기주로 하였을 때, 용화된 이후 암컷은 $12.9{\pm}0.2$일, 수컷은 $11.9{\pm}0.2$일 후 우화하였고, 수컷의 발육기간은 암컷보다 1일 정도 더 빨랐다. 기주곤충에 대한 산란율은 다른 기주곤충에 비해 북방수염하늘소 유충과 번데기에서 98.6%와 97.5%로 제일 높았으며, 우화율도 북방수염하늘소의 유충과 번데기에서 90.1%와 87.3%로 제일 높았다. 우화한 개미침벌의 성비는 대략 10:1의 비로 암컷이 우세하였고, 기주곤충에 대한 첫 산란은 북방수염하늘소 번데기에서 가장 짧아 우화한지 $4.6{\pm}0.1$일에 산란하였다. 기주곤충의 유충에 개미침벌 암컷 성충을 3마리 접종하였을 때 산란수도 북방수염하늘에서 암컷 1마리당 $62.7{\pm}2.5$개로 가장 많았다. This study was performed to investigate the immature development period, fecundity, emergence rate and sex ratio of Sclerodermus harmandi against different host insects, Monochamus alternatus, M. saltuarius and Psacothea hilaris. Full grown larvae and pupae of host insects were provided with foods. The mean larval period of S. harmandi female was $29.2{\pm}0.93\;and\;25.1{\pm}0.47$ days in larvae and pupae of M. alternatus, $27.1{\pm}0.41\;and\;26.0{\pm}0.69$ days in M. saltuarius, and $26.3{\pm}0.38\;and\;31.2{\pm}0.24$ days in P. hilaris, respectively. S. hilaris adults were emerged at $12.9{\pm}0.2$ days in female and $11.9{\pm}0.2$ days in male after pupation when hosted M. alternatus pupa. Development period in male showed shorter one day than in female. Success rate of oviposition against different hosts was higher as 98.6 and 97.5% on full grown larva and pupa of M saltuarius. Emergence rate was higher as 90.1 and 87.3% on M. saltuarius larvae and pupae. Sex ratio of emerged S. harmandi adults was approximately 10:1 (Female : Male), females showed higher emergence rate than males. The period until first oviposition after emergence in S. harmandi female was the shortest in $4.6{\pm}0.1$ days on M. saltuarius pupa. When three females of S. harmandi were inoculated on M. saltuarius larva, the number of laid eggs was the highest $62.7{\pm}2.5$ per female.

Objectives:The purpose of this study was to describe the status of mental activity participation in community-dwelling elderly and to evaluate the association between mental activity and cognitive function after adjustment for depression and anxiety. Methods:This study was based on the Suwon Project, which was a cohort comprising of nonrandom convenience samples of ethnic Koreans aged 60 years and above. All the subjects completed the study questionnaire including their demographic characteristics, current and past illnesses history, drug history, Korean version-Mini Mental State Examination (K-MMSE), Korean version of Short Form Geriatric Depression Scale (SGDS-K), Beck Anxiety Inventory (BAI). We checked how many hours per day are used for each items of 11 mental activities through the checklist. Results:Total time spent in 11 mental activities was 237.4±152.4 minutes per day. On multiple regression analysis, total time spent in 11 mental activities (MA-total), and time spent by watching television and reading book/newspaper showed statistically significant association with K-MMSE score after adjustment with age, sex, education, chronic medical illness, depression and anxiety. Conclusion:Our result suggested that mental activity may be associated with cognitive function in the elderly without cognitive impairment in the community after adjusting age, sex, education, chronic medical illness, depression and anxiety.

2007년에 잣나무림에서 하늘소과, 바구미과, 나무좀아과에 속하는 천공성 딱정벌레 군집을 말레이즈 트랩을 활용하여 조사하였다. 하늘소류 15종 184 개체, 바구미류 17종 185개체, 6종 1,246개체의 총 1,615개체 천공성 딱정벌레가 채집되었고 우점종은 왕녹나무좀이었다. 개체수에 따라 순위를 매겼을 때, 잣나무림에서 천공성 해충과 나무좀류 군집은 나무좀아과의 한 종에 의해 우점되어 생물다양성이 낮은 것으로 나타났다. 잣나무림에서 간벌은 나무좀과 암브로시아좀류의 풍부도에 영향을 미쳐 특정 임분에서의 개체군들은 간벌 1년 후 밀도가 증가했으나 그 후 감소하였다. The community of xylophagous beetles belonging to Cerambycidae, Curculionidae and Scolytinae in Korean white pine, Pinus koraiensis Siebold & Zuccarini, forests was surveyed using Malaise traps in 2007. A total of 1,615 xylophagous beetles were collected, including 184 cerambycids from 15 species, 185 curculionids from 17 species, and 1,246 scolytid beetles from 6 species, of which the dominant species was the ambrosia beetle Xyleborus mutilatus Blandford. Ranked by order of population size, the wood-boring and bark beetle community in Korean white pine showed high dominance by one species of Scolytinae, suggesting the community had low biological diversity. Thinning in Korean white pine forests influenced on the abundance of bark and ambrosia beetles, whose populations in particular stands increased 1 year after thinning, and then decreased the following year.

Objectives The aim of this study was to examine the association between the sleep pattern, chronotype (midpoint of sleep on free days) and the depressive symptoms in adults aged 19 years and over in Korea. This study also investigated the mediating effect of perceived usual stress (PUS) and self-rated health (SRH) on the association between chronotype and depressive symptoms. Methods Among the subjects of the 7th Korea National Health and Nutrition Examination Survey (KNHANES) 2016 and 2018, 16142 adults aged 19 or over responded to the survey and finally 8604 were analyzed according to the exclusion conditions. Logistic regression analysis was conducted to see the risk of depressive symptoms, suicidal ideation over sleep pattern, chronotype. Finally, mediation analysis was performed in order to clarify how PUS and SRH are associated to chronoytpe and depression. Results After controlling for potential covariates, weekly sleep duration < 5 hours, ≥ 10 hours was associated with depressive symptoms. And late bed time sleeping after am 1:00 and later midpoints of sleep was associated with a higher level of depressive symptoms. Additionally, the PUS and SRH between chronotype and depressive symptoms showed a serial multiple mediation effect. Conclusions Short or long sleep duration, late bed time and later midpoints of sleep on free days are associated with depressive symptoms. Furthermore, the mechanism between chronotype and depressive symptoms needs to be further clarified by identifying the serial multiple mediation effects of PUS and SRH.

Objectives:Among non-pharmaceutical measures for preventing cognitive impairment, involving in social activities is known to be very effective. We tried to examine the correlation between social activity and cognitive function. Methods:This study was based on the Suwon Project, a cohort comprising of non-random convenience samples of ethnic Koreans aged 60 years and above. All the subjects completed the study questionnaire which included demographic characteristics, current and past history of illnesses, drug history, Korean version of Mini Mental State Examination (K-MMSE), Korean version of Short Form Geriatric Depression Scale, and Beck Anxiety Inventory. We checked the time consumed in each 9 social activities through the checklist. Results:On multiple logistic regression analysis, the total time spent in social activities wasinversely associated with the K-MMSE score after adjusting confounding variables like age, sex, education level, depression, anxiety and vascular risk factor (β= -0.041, p=0.024). On the other hand, correlation was found between K-MMSE score and time spent in participating in religious party (β=0.053, p=0.003) as well as time spent in elder’s university (β=0.040, p=0.025) after adjustingage, sex, education, depression, anxiety and vascular risk factor. Conclusion:Our results suggest that involving in quality social activities might be more effective in improving cognitive function than spending longer total time in any social activity.

Objectives:The aim of this study was to describe subjective physical and mental health assessed by the single item self-rated physical health (SRPH), and self-rated mental health (SRMH) had influence on the cognitive decline in community-dwelling elderly. Methods:This study was based on the Suwon Project, a cohort comprising of non-random convenience samples of ethnic Koreans aged 60 years and above. 1,356 individuals were assessed at 2 time points 2 years apart for questionnaire which included demographic characteristics, medical history, Korean Mini-Mental State Examination (K-MMSE), Korean version of Geriatric Depression Scale (SGDS-K), SRPH, and SRMH. Multiple logistic regression was used to assess K-MMSE score change from the SRPH, and SRMH. Results:At baseline, both SRPH (β=0.18, p<0.01) and SRMH (β=0.19, p<0.01) score positively associated with the K-MMSE score. At follow-up, subjects with baseline lower SRMH score had significantly greater decline in K-MMSE score (β=0.09, p=0.007). However, baseline SRPH score showed no effect to follow up K-MMSE score before and after adjusting age, sex, education, number of chronic disease, SGDS-K, and baseline K-MMSE score (p=0.89). Conclusion:Brief and easily collected subjective mental health may predict the risk of cognitive decline, but subjective physical health may not.

정신건강복지법 개정 전후 응급입원 환자의 특성, 입원유지율 및형태, 재입원율 비교

신수진(Sujin Shin),고상현(Sang Hyun Koh) 대한사회정신의학회 2020 사회정신의학 Vol.25 No.2

목 적 : 2017년 개정된 ‘정신건강증진 및 정신질환자 복지서비스 지원에 관한 법률’ 시행 전후 응급입원 환자군의 특성, 입원유지비율, 입원 형태, 재입원율의 변화를 알아보고자 연구를 수행하였다. 방 법 : 2016년, 2018년 각 6개월 동안 서울특별시 은평병원에 응급입원한 환자를 대상으로 445건의 의무기록을 후향적으로 검토하였으며, 2016년에 입원한 224명과 2018년에 입원한 221명의 특성, 입원유지율 및 형태, 재입원율을 통계적으로 비교하였다. 결 과 : 정신건강복지법 개정 전후 두 군간 사회인구학적, 임상적 변인은 차이가 없었다. 응급입원에 이어 입원이 유지된 비율에는 두 군간 차이가 없었으나, 물질 사용 장애군을 제외 시 입원유지율이 감소하였다. 입원이 유지된 군에서 자의 입원의 비율은 증가하였다. 또한 응급입원 후 퇴원한 환자 중 1개월 및 3개월 이내의 재입원율은 증가하였다. 결 론 : 응급입원에 이어 입원을 지속하는 환자 중 자발적 입원의 비율이 늘었으며, 이는 정신건강복지법의 개정 목적에 부합하는 변화라고 할 수 있겠다. 하지만 일부 환자 집단에서는 입원을 지속적으로 유지하는 것이 어려워졌으며, 응급입원 퇴원 후 단시일 내의 재입 원율이 증가는 변화도 관찰되었다. 이러한 사항을 고려하여 정신건강복지법의 보완과 개선이 고려되어야 할 것이다. Objectives : The research was conducted to compare the characteristics, rate and types of admission continuation, and rate of readmission in psychiatric emergency hospitalization patients before and after the revision of Mental Health Promotion and Welfare Act. Methods : The medical records of the 445 patients who underwent psychiatric emergency hospitalization at Seoul Metropolitan City Eunpyeong Hospital in 2016 and 2018 were reviewed retrospectively. The clinical and sociodemograhpic characteristics, rate and types of admission continuation, and rate of readmission were compared between 224 patients who admitted in 2016 and 221 patients who admitted in 2018. To compare the characteristics of the two groups, t-test and chi-square test were performed. Results : There is no difference in clinical and sociodemographic characteristics between 2016 and 2018 group. There was no difference in the rate of admission continuation before and after the revision of act, while the rate significantly decreased from 61.9% to 50.0% when patients with substance use disorder were excluded from overall group. Among those who maintained hospitalization, the proportion of voluntary admission increased from 5.5% to 13.1%. The rate of readmission after discharge from the emergency hospitalization within 1 and 3 month period increased after the revision of the act. Conclusion : This study showed that the proportion of voluntary admission increased in admission continuation, and this change is in accordance with the purpose of the revision of the Mental Health Promotion and Welfare Act. On the other hand, the rate of admission continuation decreased in a subgroup of patients, and the readmission rate after discharge from the emergency hospitalization increased. Current findings suggest that the Mental Health Promotion and Welfare Act needs further complementation and improvement.
